Enhancing the transmission and distribution of electricity is a priority to ensure a reliable and resilient power supply, as demand increases and grid challenges mount.

Providing more electricity to meet growing global demand for power has put a spotlight not only on adding more generation to the grid, primarily through construction of new power plants, but on improvements to the grid itself. Enhancements to support power grid reliability include investments for a variety of technologies, such as battery energy storage systems (BESS), advanced transmission lines, smart grid infrastructure, and distributed generation. Upgrades also focus on improved grid monitoring and control systems that allow for better and faster response to fluctuations in demand and disruptions caused by weather, equipment, or other issues.

“Needed enhancements span across condition monitoring, advanced data analytics, fire mitigation, and improved system control mechanisms,” said John Russell, senior director, Solution Consulting at AspenTech, a provider of software and services for the process industries. “Reliability in these systems is crucial not only for preventing downtime but also for ensuring that power is consistently delivered to consumers with minimal disruptions. Specifically, key areas for enhancement include the implementation of condition-based maintenance, improved data collection with smart meters, AI [artificial intelligence]-powered asset management, and advanced control technologies for both transmission and generation systems. By integrating modern technologies, these systems can proactively address failures, optimize performance, and respond to real-time conditions.”

“Reliability is central to the modern power grid, especially as we integrate more renewables and electrify transportation and heating. Much work has been done in generation and distribution, driven by smarter hardware, predictive software, and data analytics,” said Brandon Young, CEO at Payless Power, a Texas-based electricity group. “On the generation side, predictive maintenance technologies become game-changers. IoT [Internet of Things] sensors and AI are monitoring equipment like turbines and transformers in real time to pinpoint potential failures before they occur. That way, downtime is kept to a minimum, and power generation stays efficient.”

Utilities and grid operators are studying a variety of ways to improve the reliability of power generation and delivery, with data at the heart of much of the research.

The company offers technical expertise to solve technical and often complex problems associated with power generation and delivery.

“Reliability enhancements should be approached as a comprehensive, multi-pronged strategy that addresses design concerns and utilizes new and emerging technologies for improved data analytics,” said Michael Bennett, chief transformation officer at Powin, a battery energy storage company. “Up front, suppliers need to design and engineer components with reliability as a core principle. This includes using advanced materials, robust designs, and high-quality manufacturing processes.”

Bennett added, “Ensuring transmission, distribution, and generation assets are equipped with IoT sensors for real-time data collection, monitoring, and reporting capabilities has become a core focus over the past few years as well. These sensors provide operators with actionable insights into system performance and potential issues, allowing them to leverage both cloud and on-premise data to uncover complex insights, correlations, and predictions.”

Thomas L. Keefe, vice chair and U.S. Power, Utilities & Renewables Sector leader for Deloitte, said, “Increasing visibility and control through advanced grid technologies” is a major part of increasing grid reliability. “Sensors embedded throughout the network, including smart meters, automated control systems, and advanced monitoring tools, can provide real-time data on energy flow, equipment health, and grid stability,” said Keefe. “Analyzing sensor data can allow operators to anticipate equipment failures before they happen, preventing outages, enhancing the utilization of existing resources, and ultimately increasing grid reliability.”

Efficiency a Key Part of Upgrades

Upgrades to transmission infrastructure (Figure 1) are just part of the work being done to improve power grids. The need for maintenance, particularly during a period of transition to digitization of energy systems, is evolving as well.

“There are several proactive maintenance solutions to improve grid reliability, such as implementing distributed intelligence [DI] systems for real-time monitoring and diagnostics,” said Matt Smith, who leads the global business and product strategy for the grid management business at Itron, a global group helping utilities develop innovative solutions for their operations. “Additionally, predictive analytics and edge intelligence can identify trouble spots below the substation, enabling utilities to automate fault isolation and repair processes, reducing the need for manual intervention, which leads to faster recovery times and improved grid stability. This integrated approach allows for a more efficient, resilient power grid, especially during times of increased demand or extreme weather events.”

Actalent is a global company specializing in engineering and sciences services, along with talent solutions. Amanda Neuenfeldt, an energy management systems modeling lead engineer with the group, provided POWER with insight into emerging technologies that support the power grid. Learn more in this POWER Interview.

Smith listed what he called “key enhancements” to improve the overall reliability of electricity transmission and distribution, including decentralizing grids.

“Traditional centralized grids are vulnerable to cascading failures during extreme weather events, like major hurricanes and heatwaves, which are becoming more prevalent. Switching to a decentralized model, which includes incorporating distributed generation resources [such as renewables] closer to demand points, improves resilience,” said Smith. The Itron executive also noted the importance of leveraging intelligent grid edge solutions. “Integrating distributed intelligence into utility systems enables grid sectionalization, allowing power to be rerouted automatically. This reduces outages by leveraging real-time data to detect anomalies more efficiently than manual inspections.”

The use of distributed generation is helping provide additional power apart from centralized power plants. Advanced metering infrastructure is helping monitor power usage in real-time, and supporting demand response programs. And then there are efforts to combat the problems associated with keeping the lights out during extreme weather events.

“At the top of the list for transmission and distribution is grid hardening and modernization,” said Young. “Utilities are replacing aging infrastructure with weather-resilient materials, and deploying smart grid technologies such as automated reclosers, which isolate faults and reroute power almost instantly, reducing outages. The growth in smaller energy sources, such as rooftop solar and batteries, has been supported by distributed energy resource management systems [DERMS] that aggregate them to provide stability to the grid in times of peaks or emergencies. Future technologies, like grid-forming inverters, will stabilize grids with high renewable penetration, controlling voltage and frequency independently and acting as virtual power plants.”

Itron’s Smith said, “EV [electric vehicle] charging stations are an increasingly valuable resource that can be quickly repurposed before and during grid failures to provide grid services and backup power, respectively. Additionally, EV batteries within vehicles, specifically within larger vehicles like buses, offer a robust source of energy storage. These batteries can be tapped during outages to enhance grid resilience and maintain power for critical operations, making them an essential component in modernizing grid infrastructure to cope with outages.”

Deloitte’s Keefe said that reinforcing physical infrastructure is another important step. “Strengthening, upgrading, and hardening key components, such as power lines, substations, and transformers, can not only help handle higher loads but also reduce transmission losses and improve resiliency and energy delivery efficiency,” said Keefe. “A few states have signed bills mandating that utilities consider grid-enhancing technologies as a shorter-term solution in their IRPs [integrated resource plans]. Replacing outdated transformers with high-efficiency models can cut energy consumption by up to 12%, further boosting grid efficiency.”

Keefe added, “Deploying grid-enhancing technologies and advanced conductors to add capacity and flexibility to the existing transmission system [improves] transmission reliability. These technologies offer a cost-effective way to expand capacity compared to rebuilding transmission lines. Upgrading to high-efficiency conductors can minimize transmission line losses by 10% to 20%.”

Keefe also noted how model predictive control (MPC) technology can support reliability. “MPC uses a mathematical model to predict future system behavior within a set timeframe. It is popular in power electronics for managing constraints, multiple inputs and outputs, and nonlinearities. Unlike other control methods, MPC explicitly considers system constraints and optimizes control actions over a prediction horizon. This results in better performance, lower energy consumption, and increased reliability in power electronic applications. In renewable energy systems like photovoltaic [PV] and wind energy, MPC can optimize power extraction and facilitate maximum power point tracking [MPPT]. It also coordinates multiple energy sources, storage devices, and loads to ensure optimal performance and reliability.”

Grid Projects

Jersey Central Power & Light (JCP&L), a subsidiary of FirstEnergy Corp., in December began construction on infrastructure upgrades designed to enhance electric reliability for customers in three Morris County communities in New Jersey (Figure 2). The work, scheduled to be completed in October of this year, is part of JCP&L’s New Jersey Reliability Improvement Project, which is an element of the company’s rate review settlement approved by the New Jersey Board of Public Utilities in February 2024. Equipment enhancements will take place along more than five miles of power lines in Chester, Washington, and Roxbury townships.

Doug Mokoid, FirstEnergy’s president for New Jersey, in a statement said: “The upgrades we’re making under the New Jersey Reliability Improvement Project are part of our commitment to providing safe, reliable electric service for all our customers. These improvements, in particular, target areas where customers have experienced some of the most frequent outages in recent years.”

The New Jersey Reliability Improvement Project is a two-phase effort to enhance reliability for customers on high-priority lines selected based on historical outage data. The first phase, which includes at least $95 million in upgrades, is set to be completed over the next three years, according to FirstEnergy. The second phase, which includes longer-duration projects, is expected to be completed by year-end 2028.

The upgrades include replacing existing infrastructure with thicker, stronger wires and poles that can carry more electricity and provide more resiliency in storms. The work also includes upgrading fuses, and installing additional devices and reclosers that allow power to be rerouted to adjacent lines when an outage occurs, minimizing the number of impacted customers.

Several projects are underway or planned to build new high-capacity transmission lines to facilitate power transfer across long distances, often to move renewable energy resources from remote, rural areas to the grid. Advanced conductor materials are being used to reduce transmission losses. Smart grid tech is being deployed for dynamic load management, and battery storage is being installed along the grid (often at substations) to help with grid flexibility and balancing.

The U.S. Department of Energy (DOE) last year awarded $2.2 billion to eight electric transmission and microgrid projects across 18 states, with a goal of adding electricity delivery capacity and strengthening the grid against extreme weather. Jennifer Granholm, the Energy Secretary during the Biden administration, at the time said the money was part of a program to add 1,000 miles of transmission lines and 50,000 MW of electricity to the grid. Granholm at the time said, “and there’s much more to come,” although it’s not known how the Trump administration will approach funding for electricity transmission and distribution (T&D).

The DOE said $700 million would go to the North Plains Connector project, a high-voltage direct-current power line that would create the first large-scale grid connection between the Eastern and Western interconnections, the U.S. grid systems divided by the Rocky Mountains. Minnesota-based Allete Inc. and transmission builder Grid United are developing the project.

The Utah Office of Energy Development was awarded nearly $250 million to install 250 miles of advanced conductor cables, increasing line capacity to support delivery of 500 MW of renewable energy (Figure 3) across six states.

Another grant, for $30 million, was made to the New York Power Authority for its Clean Path New York project. That strategy is designed to deliver 1,300 MW of renewable energy from upstate and western New York to New York City, which the DOE said would help reduce reliance on coal- and natural gas–fired power generation.

Handling Increased Demand for Electricity

Technology innovations to improve power generation, transmission, and distribution have brought more complexity into power networks. That means utilities and grid operators are rethinking some of their earlier practices to adapt to a changing energy landscape.

Jon M. Williams, CEO of Viridi, a battery energy storage company, said, “The energy system is on the brink of a paradigm shift that will profoundly reshape energy transmission and distribution. After decades of relatively stable demand [no load growth], the grid must now manage an enormous demand increase resulting from industrial onshoring, the growth of data centers and AI, and, perhaps most significantly, the electrification of heat and transportation. Complexity has also been added as distributed generation resources, like rooftop solar, complicate system management. These antiquated 19th-century grids are decentralizing, and the transition must be accommodated.”

Williams told POWER: “The solution to this challenge will not be to redesign and rebuild the grid of the 19th century. Instead, we must use new advances that prioritize safety, reliability, and enhancing system level efficiencies while focusing investments on technologies that provide layers of benefit. There is no greater technology to benefit power grids as we electrify everything than intelligently managed distributed energy storage. Distributed storage can enhance the value and operability of on-site generation. With advanced connectivity, it can be leveraged as a ‘virtual power plant [VPP]’ to better enable host facility loads for grid support through constraints and failures in real time.

“Behind-the-meter distributed energy storage has the potential to improve resilience, support decarbonization, shave peaks, enhance value of behind-the-meter generating assets, enable utilities to pursue beneficial ‘non-wires’ alternatives, and avoid the massive costs that a replacement of the old grid would entail,” said Williams.

Utilities have developed programs to support a reliable power supply. The American Public Power Association (APPA) has a Reliable Public Power Provider, or RP3, program “that recognizes utilities that demonstrate high proficiency in reliability, safety, workforce development, and system improvement.” The group’s list includes utilities, both large and small, from across the U.S.

Said Young, “Real-world examples show the benefits: Florida Power & Light’s ‘Storm Secure’ program—undergrounding power lines and deployment of smart grid—has reduced outage durations after a hurricane like Irma. Similarly, Pacific Gas & Electric is now using AI to predict the risks of wildfires by analyzing weather, vegetation, and grid conditions in order to take action before disaster strikes.

“This brings, in short, today’s enhancements in reliability toward the goal of making the grid smarter and more resilient as AI and other power-hungry needs increase the demand for energy. Advanced software, durable hardware, and data-driven systems are revolutionizing how we manage and distribute electricity for future needs,” he said.

“The process of monitoring and setting up a system to proactively maintain assets to extend their lifecycle and prevent malfunctioning is also known as ‘asset lifecycle management (ALM)’,” said Terry Saunders, Worldwide Utilities and Industry leader at IBM. “As organizations continue to look for ways to conduct more efficient, cost-effective, and sustainable operations many are turning to ALM. For energy equipment specifically, ALM practices may include installing sensors and using cameras for immediate eyes on equipment to identify factors affecting performance, and using AI-infused software that recommends specific maintenance directed by the data. By approaching maintenance and operations management from a preventive, data-driven approach companies can ensure that their systems are performing optimally for longer, ultimately maximizing their return on investment.”

Tyler Lancaster, partner at Energize Capital, a group that invests in climate technology, including renewable energy, told POWER: “A big shift in the power sector has been moving away from cycle-based maintenance programs to data-driven, proactive maintenance programs. Some aspects can also be automated to drive further efficiency and reliability. This is true across every form of power infrastructure.

“For example, historically, utility poles were inspected on a cycle once every five to 10 years. Over time, utilities and their service providers have built up a large amount of data and information on common failure modes for utility poles,” said Lancaster. Increasingly, analytical models can be applied to estimate the probability of failure for each pole based on the type of wood, environmental factors like moisture, location, etc., and can tailor maintenance activities to inspect and repair higher risk poles sooner.

Lancaster said it’s difficult to standardize operations to improve reliability. “This is a key challenge for the power sector, as operations tend not to be ‘one-size-fits-all.’ Different grids, with different environmental factors and natural systems, with different power infrastructure configurations—generation mix, T&D system setup, consumption segmentation and load profile, etc.—require tailored operations to ensure reliability. Where operations can be standardized is through the use of modular and adaptable technologies which can be easily configured to the unique needs of a specific power plant or grid operator’s context.”

“Standardization can play an important role in power system reliability as it promotes consistency, predictability, and interoperability,” said Keefe. “It can help reduce human error, and improve communication and coordination—especially during emergencies, with faster response times, etc.”

Combating Failure

Working to eliminate grid failures, or at least mitigate their impacts, is a goal of those working with utilities and grid operators. That can involve gathering data, knowing how to interpret it, and also having systems in place to deal with issues as they arise.

“Reliability at the equipment or component level is driven by two key factors—probability of failure and impact of failure. Enhancements that address one or both these factors are key to improving reliability,” said Steve Morris, a managing director with FTI Consulting’s Construction, Projects & Assets practice. “Whether it’s a power plant or the grid, reducing the probability of failure comes down to maintaining the assets in good operating condition through preventive and condition-based maintenance. Reducing the impact of failure is reliant on having redundancy in the system so that the failure of a single asset or component doesn’t reduce plant or system performance.”

Morris said, “For a power plant or electric substation, this is typically achieved by having spare capacity that can be used if there is a failure. For example, instead of having one power transformer in a substation running at full capacity, you would have two running at 50% or less capacity. If one fails, you can switch the other with no impact on the system. For the transmission grid, in most cases, if a single transmission line fails, there is sufficient capacity to switch to another transmission line, which has spare capacity. For the distribution grid, redundancy is achieved by interconnecting circuits and having auto reclosers, which can automatically restore after a fault is cleared, and sectionalizers that can section off parts of the system to reduce the number of customers impacted by an outage.”

Sally Jacquemin, vice president and general manager, Power and Utilities at AspenTech, told POWER: “Redundancy plays a vital role in maintaining the reliability and stability of both power plants and power grids. As the energy landscape shifts toward greater integration of renewable sources like wind and solar, the variability of these resources increases the importance of backup systems. Redundant infrastructure, including reserve generation and microgrids, ensures that power continues to flow smoothly during both planned and unexpected disruptions, such as outages or system failures, minimizing the risk of blackouts.”

Jacquemin said, “Historically, utilities maintained excessive reserve generation to protect against worst-case scenarios, ensuring power availability in case of failure. Today, however, there is a balance between maintaining enough redundancy to prevent outages and avoiding over-investment in reserve capacity. Modern systems focus on understanding the critical threshold of necessary redundancy, ensuring operational efficiency while still providing reliability in the face of unexpected events like sudden generation loss or extreme weather conditions.”

Jacquemin added, “Microgrids and localized redundancy solutions are increasingly important as they allow certain areas to maintain power even when the larger grid is disrupted. Powered by local generation sources like solar or batteries, microgrids can operate independently, providing resilience during storms or grid failures. The integration of renewable energy further highlights the need for redundancy, as renewables introduce variability that requires additional backup systems, such as storage or traditional generation, to ensure a reliable and stable power supply.”

“Redundancy is most important for the transmission system as North American Electric Reliability Corporation [NERC] requires that the transmission system must be able to handle the failure of a single component without causing a significant outage,” said Morris. “Therefore, transmission lines and substations are designed with redundancy. Redundancy is less important for power plants as typically a single unit of a power plant only produces a small portion of the power on the grid. In addition, power grids are required to have reserve capacity to be able to handle unit unavailability, maintenance, and higher than normal demand. The distribution system is similar to power plants in that most equipment serves a small number of customers, so a failure has little impact on the overall grid. Therefore, there is little redundancy in the system, other than in substations.”

Morris listed several ways to enhance reliability of power generation and the transmission and distribution system. He noted that advanced distribution management systems can automatically detect faults, and also identify the impacts of anomalies. He also noted a distributed energy resource management system “monitors, optimizes, dispatches, and manages all types of distributed energy resources including black start for grid shutdowns. Dynamic line rating calculates real-time transmission capacity of a line to optimize capacity usage to reduce congestion.” Meanwhile, an “asset performance management system monitors real-time equipment condition to identify [any] need for maintenance or indicate increasing risk of failure.” Morris also noted what he called “non-intrusive inspection,” which can help operators “understand power plant equipment condition without taking it apart. [This] includes technologies such as ultrasonic, radiography, eddy current, magnetic particle, acoustic emission, dye penetrant, leak testing, vibration analysis, and thermography.”

Lancaster said there are programs that can be implemented to enable proactive replacement and/or restoration of older equipment—both software and hardware—in power plant and power grid systems. He referenced his earlier comments about power poles, and said, “Another example is for transformers. Transformers are a key piece of equipment for the electric transmission and distribution system. They convert high-voltage electricity down to the lower voltages, eventually to the 120V type that we commonly use in our homes and businesses.

“There are several methods that have emerged to predictively identify transformer failure through sensor technology and data science or machine learning techniques,” said Lancaster. “For example, sensors that measure the accumulation of dissolved gas particles in the oil contained within a transformer can prevent transformer failure before it causes broader damage to other power grid equipment nearby.”

Utilizing Digital Twins and Energy Storage

Ildi Telegrafi, a policy fellow at the Alliance for Innovation and Infrastructure, said digital twins—often used to study power generation equipment—can also be a vital part of understanding electricity transmission and distribution.

Cybersecurity and Grid Reliability

Shankar Somasundaram is CEO at Asimily, a risk management platform that secures Internet of Things (IoT) devices for healthcare, manufacturing, public sector, and other industries that depend on numerous connected devices. Somasundaram talked with POWER about how enhancements to support grid reliability also should address cybersecurity issues (Figure 4), especially with more digitization in power plants and along the transmission and distribution system.

“Cybersecurity has become an increasingly fundamental variable for power system reliability as utilities digitize operations and add more network-connected devices and equipment,” said Somasundaram. “As headlines in this industry continue to show, a more interconnected power infrastructure—particularly its operational technology [OT] systems that directly control physical equipment—means that cyber vulnerabilities can directly impact system reliability.

“In transmission and distribution systems, cybersecurity measures need to protect essential OT components like supervisory control and data acquisition [SCADA] systems, smart meters, and automated switches through authentication, encrypted communications, and continuous network monitoring,” said Somasundaram. “Power plants require additional protection for their digital control systems, including distributed control systems [DCS] and programmable logic controllers [PLCs]. This necessitates network segmentation, regular security patching, and strict access controls to prevent equipment damage or forced outages.”

Somasundaram told POWER, “Supply chain security and the human element are equally crucial for reliability. Utilities must verify the integrity of software updates and new internet-connected equipment while maintaining comprehensive training programs for personnel who operate and maintain OT systems. Building a culture of cybersecurity awareness cannot be glossed over.”

Somasundaram said as more automation enters maintenance programs, more vulnerabilities to cyberattacks are exposed. “From a cybersecurity perspective, every component in a power plant and the grid is potentially vulnerable if it has an access port. Historically, physical protection and maintenance have provided a strong defense. However, as network access and its many benefits are deployed more, this physical security is becoming less effective,” said Somasundaram. “Cybersecurity maintenance for power plants is like the price of democracy—it requires constant vigilance. This vigilance involves always detecting potential and current attacks. This requires processes backed by software that continually look for evidence of such weaknesses and attacks. When evidence is found, it’s important to act quickly to close security gaps or, in the worst-case scenario, terminate a successful attack.”

Somasundaram added, “Fortunately, much of this has been automated by the software industry. Implementing people and processes to leverage this technology effectively and act quickly, however, is not always in place. Ensuring this implementation is key to maintaining automated maintenance and reliability.”

“The clean energy transition is driving the energy industry toward a new dynamic with vast renewable energy resources that can supply a high volume of energy over the year but with high intermittency,” said Telegrafi, who is also an analyst for New York-based utility Con Edison. Telegrafi said the need for bidirectional power flow management, and the inclusion of energy storage onto the grid “to stabilize intermittency and flatten the peak,” means “the tools necessary to manage this continually changing dynamic are digital. Balancing an ever-increasing power dynamic that must satisfy inconsistent load with intermittent generation supported by storage components requires the creating of a digital twin of the grid.” Of course, cybersecurity must also be considered whenever digital technology is added to a system (see sidebar).

Telegrafi said the digital twin “models the components individually and the systemic constraints binding operation via mathematical formulas. These mathematical formulas allow for optimization of the dynamic from the current dynamic to the future clean energy equilibrium that industry establishes. The digital twin can be manipulated freely to add or remove components into the digital emulation of the grid’s dynamics, enabling ‘what if’ scenarios for application toward strategically planning investment and policy.” Telegrafi said Optit S.r.l., an optimization and solutions group, has been working on these projects in the U.S.

Powin’s Bennett also noted the importance of digital twins to “enable continuous monitoring, simulation, and optimization of power plant or grid equipment, providing a real-time view of asset health.” Bennett said having “virtual replicas of physical assets” is just one of “several components of an effective, automated maintenance program to ensure the reliability of power plants and grid.” He cited condition-based maintenance, or CBM, which enables “transitioning from predefined maintenance schedules to dynamic, condition-based programs that rely on real-time monitoring and performance data. SCADA [supervisory control and data acquisition] systems and IoT devices provide the necessary data for this approach.”

Bennett said predictive maintenance also is important. “Using AI and machine learning algorithms to analyze historical and real-time data from sensors, enabling the prediction of failures before they occur… [where] data sources can include environmental conditions, operating history, and current performance metrics,” he said. There is also automation, where “automating data correlation in the cloud allows predictive insights to be seamlessly integrated into control systems or maintenance scheduling tools. This reduces response time and ensures resources are allocated efficiently to address the highest-priority issues.” Inspections of power plant assets, and the power grid, using robotic systems and drones “can automate inspections of hard-to-reach areas, reducing the risk to personnel and minimizing downtime,” said Bennett.

FTI Consulting’s Morris said, “To enable proactive replacement/refurbishment of older equipment requires understanding several elements. First, there is a need to understand the condition of the asset and what the probability of failure of that asset is. Second, there is a need to understand the consequence of failure in terms of its impact. Third, the probability and consequence of failure need to be combined to understand the amount of risk. Once risk is known, it can then be assessed against the cost of replacement/refurbishment to determine the appropriate time for an intervention.” For example, a well-informed user can plan to replace equipment when the risk value exceeds the cost of replacement.

Morris continued, “In order to understand the condition of the asset, there is a need to invest in condition monitoring hardware, which varies based on the application. These are typically wired or wireless devices, which can be placed on equipment to collect different types of data. In addition to the hardware, there is a need for asset performance management software, which takes the data from the monitoring devices and performs analysis to identify the risk of failure. It does this by creating a digital twin of the asset and analyzing the data being provided by sensors and monitors to simulate the impact on the asset’s condition. This software typically can also determine the consequence of failure and calculate the risk value.”

Viridi’s Williams said the use of BESS can address several grid-related issues. “By charging batteries when energy is abundant and lower cost—in many parts of the U.S., this occurs during peak solar production—and discharging when energy is at a higher price or when the grid is operating at a higher carbon intensity, distributed, behind-the-meter storage has the capacity to provide significant benefits to the host site,” said Williams. “These benefits include active management of on-site generation and cost reduction through peak shaving, while also supporting the grid by releasing energy when needed—all for the benefit of the battery owner. However, fulfilling these roles requires that the BESS be absolutely safe, and they must have advanced communications and controls capacity so they can be monitored and managed from anywhere and leverage real-time opportunities to provide forecasted return on investment.”

“A good example of the diverse benefits from distributed storage is the 600-kWh Viridi BESS installation [Figure 5] in occupied space at the Hauptman Woodward Medical Research Institute (HWI) in Buffalo, New York,” said Williams. “HWI had an undersized interconnection to support installation of a new cryogenic electron microscope. This need was satisfied by installation of the Viridi BESS, which charges in moments of lower power draw and discharges when the building is peaking to provide adequate power for this equipment whenever it is needed. However, when not used for this purpose, HWI uses the BESS in an automated fashion to peak shave, setting a kW ‘ceiling’ on operations that results in cost savings and reducing local grid strain. In this way, the BESS fulfills the promise of energy storage, which benefits both the host and the overall electric ecosystem.”

Jumping the shark: New study reviews the breaching behavior of sharks and rays

February 24, 2025

Jeff Prescott

blacktip shark breaching Featured great white shark Science sharks thresher shark why do great white sharks jump why do sharks jump No Comments

One of the most iconic images of shark behavior is a great white shark hitting its prey so hard from below that the whole shark flies out of the water. This behavior, called “breaching,” has been documented in many species, and is useful for a variety of ecological functions, not just hunting. I spoke to authors of a new review paper about this incredible phenomenon.

Figure 1 from Klimley et al. 2024. Caption reads: Breaching behaviors by common thresher (Alopias vulpinus) (a), pelagic thresher shark (Alopias pelagicus) (b), bull shark (Carcharhinus leucas) (c), shortfin mako shark (Isurus oxyrinchus) (d), white shark (Carcharhinus carcharias) (e), salmon shark (Lamna ditropis) (f), blacktip shark (Carcharhinus limbatus) (g), bronze whaler shark (Carcharhinus brachyurus) (h), and basking shark (Cetorhinus maximus) (i). The photographers, email addresses, dates, and locations and dates of the filmed breaches are given in Appendix 1

“Breaching occurs when an aquatic animal propels itself entirely out of the water and into the air, landing forcefully on the surface and causing a significant splash as it displaces the water upon impact,” Dr. Alison Kock, a marine biologist with South African National Parks and a coauthor on the recent study, told me. “The breaching behaviour of sharks has always fascinated me. The first time I saw a great white shark was when it launched itself entirely out of the air, chasing after a Cape fur seal at Seal Island, False Bay, Cape Town. The sight of the massive shark in the air with gaping jaws and the sound of the splash when it landed, is etched in my mind. I knew at that moment that I wanted to spend the rest of my life studying these powerful and incredible predators. Since that moment, more than 26 years ago, I have observed the behaviour 1000s times with great whites.”

Dr. Tobey Curtis, a shark scientist who works for NOAA Fisheries and a coauthor on this study, told me that “the coolest thing about seeing sharks breach is that it’s usually so unpredictable. You can stare at the surface of the water for hours or days and not see anything. And then all of a sudden there’s this big animal hanging above the horizon, and by the time your brain computes what you’re looking at, there’s a thunderous explosion of water. Even for experienced field researchers who have seen lots of cool things on the water, it can be a jaw-dropping event. It’s absolutely spectacular behavior to witness up close.”

Prior to this review paper, breaching in sharks and rays had been noted in the literature, but usually as brief anecdotal natural history observations. The global team of experts wanted to create a one-stop-shop, summarizing and synthesizing everything known about this type of behavior to identify gaps in knowledge that can shape future research directions.

Dr. Kock pointed out that lots of marine animals engage in some kind of breaching behavior, including whales, dolphins, seals, and many species of bony fish. And, like sharks and rays, they do it for many different reasons. “What amazed me was how widespread breaching is among different shark and ray species and the various reasons behind it,” Dr. Kock told me. “We discovered that at least 19 species breach to remove external parasites, 4 to clear their gills, and another 4 to expel faeces or internal parasites. For feeding, 10 species used breaching to chase prey, while 8 did it to concentrate or stun prey. In communication, at least 8 species breached during courtship chases, 6 to attract others, and 1 to repel them. Breaching also appears to be an escape tactic, with 14 species using it to escape predators. Lastly, we recorded at least 4 species breaching and expelling pups during birth! Female manta rays, devil rays, and eagle rays leap out of the water to give birth, with the pressure from landing thought to help release their large pups!” The paper includes a list of links for people to view YouTube and Instagram videos of many of these behaviors.

“The first surprise to me was how many species from widely divergent taxa have been documented to breach,” Dr. Curtis told me, noting that he personally had seen many species breach while on research expeditions. “We all know about white sharks breaching to capture seals, but why would a filter-feeding manta ray expend so much energy to jump out of the water? The second surprise was that after all of the team’s efforts, we still don’t know why most shark and ray species breach. We collated a number of hypotheses, but at the end of the day we’re mostly still just making informed guesses.”

The paper closes with a thoughtful and thorough list of suggestions on how future researchers can test these hypotheses, and hopes that the increasingly widespread availability of high quality cameras among oceangoers means more anecdotal observations will keep pouring in. And by working together, as this team of experts did, we can help to put these puzzle pieces together and learn something about these incredible animals.

10-minute ambulance service blinkit blinkit ambulance blinkit ambulance service News Startups No Comments

Quick commerce startup Blinkit – acquired by Zomato in 2022 – has now debuted a 10-minute ambulance service, allowing users to access it through the app. After groceries, fashion items, printing documents, stationery, and more, Blinkit has announced this new service. Currently being rolled out as a pilot, the service is expected to expand in a phased manner.

Blinkit – which posted a revenue of ₹1,156 crore in Q2 FY25 – has initially launched its new 10-minute ambulance service in Gurugram. For now, the service will be available in the city with five ambulances. Each ambulance under this new service will come with a paramedic, an assistant, and a trained driver.

Additionally, these ambulances will be equipped with essential life-saving equipment, including oxygen cylinders, an Automated External Defibrillator (AED), a stretcher, a monitor, a suction machine, and necessary emergency medicines and injections.

“We are taking our first step towards solving the problem of providing quick and reliable ambulance service in our cities. The first five ambulances will be on the road in Gurugram starting today. As we expand the service to more areas, you will start seeing an option to book a Basic Life Support (BLS) ambulance through the Blinkit app,” Dhinsa wrote in his post.

However, CEO Albinder Dhindsa also mentioned that the service will expand to all major cities within the next two years. In his post, a photo displays a price tag of Rs 2,000. More importantly, the photo also includes a line stating a condition that neonatal or ventilator care is not supported.

Originally founded as a grocery delivery platform, Grofers, back in 2013 – Blinkit now operates in around 44 cities across the country, including tier-II cities like Haridwar, Jodhpur, Mohali, and Rohtak, among others. Speaking about its financials, Blinkit reported impressive growth in the September quarter of the financial year 2024-25 (Q2 FY25), with revenue more than doubling from ₹505 crore to ₹1,156 crore. On a quarter-on-quarter basis, revenue surged by 23%, rising from ₹942 crore.

Going forward, Blinkit plans to expand its network to 1,000 dark stores by the end of the financial year 2024-25, with an aim to double this number by 2026. Notably, Zomato initiated its Qualified Institutional Placement (QIP) issue in November 2024, aiming to raise ₹8,500 crore (~$1 billion). This move becomes even more significant as the funds raised through the QIP will primarily support the company’s quick commerce unit – Blinkit.

This development comes at a time when the Indian quick commerce sector is witnessing intensified competition, with major giants, including Amazon, eyeing entry into the market. This will further raise the bar for Blinkit and its current rivals – Zepto, BigBasket, Swiggy Instamart, and others. Meanwhile, the Indian quick commerce market is valued at $3.34 billion in 2024 and is expected to reach $9.95 billion within the next five years, with a CAGR of over 4.5% during this period.

The Evolving State of Power Plant O&M

February 23, 2025

asset management Business Digital Transformation electrification energy infrastructure Energy Security Full Coverage grid modernization News O&M operations and maintenance Power power grid reliability power plant efficiency predictive maintenance renewable energy O&M Safety Supply Chains Technology Trends Workforce No Comments

As power plants confront aging infrastructure, surging demand, and the sweeping changes of rapid electrification, operations and maintenance (O&M) are being redefined to tackle unprecedented challenges and seize new opportunities.

In December 2025, the North American Electric Reliability Corporation (NERC), the region’s designated electric reliability organization, issued a sobering assessment of the power sector’s outlook for the next decade. More than half of North America may be at risk of electricity shortages, it warned. The scenario is exacerbated by the accelerated retirements of 78 GW of aging, fossil-fueled capacity—with an additional 37 GW announced but not yet confirmed—and sluggish progress on new resource additions. Compounding the challenge, power demand is projected to soar by 15% over the next decade, driven by rapid electrification, industrial growth, and the increasing energy needs of the data-driven economy.

In this context, the region’s existing fleet will play an outsized role, underscoring a role for their sound operations and maintenance (O&M). However, NERC also flagged forced outages as a critical and growing concern for the power sector, noting that unplanned outages caused by equipment failures, insufficient maintenance, and resource shortfalls pose significant reliability risks, most prominently during extreme weather events. Without robust O&M practices, these issues could further undermine the grid’s ability to meet rising demand, particularly as winter peaks begin to outpace summer peaks. That has exposed new vulnerabilities in resource adequacy planning, it said.

But as experts told POWER, the realm of O&M is itself rapidly evolving to address new complexities and expectations introduced by the rapid transformation. As IHI Power Solutions Director of Business Development Doug Machon notes, O&M emerged historically as a straightforward business function managed internally by utilities operating within regulated monopolies. The realm began a shift in the 1990s, as competition, introduced by electricity deregulation, ushered in third-party O&M services that offered basic maintenance, compliance support, and operational oversight. Today’s landscape adds a growing involvement from private equity investors, a decline in long-term power purchase agreements, and the rise of diversified energy portfolios—including renewables, distributed energy resources (DERs), and hybrid configurations.

No longer limited to routine tasks, modern O&M necessitates “a higher level of expertise and innovation in plant operations,” says Machon. The significant shift has catalyzed “the development of comprehensive O&M strategies designed to maximize efficiency, reliability, and profitability in an ever-changing energy landscape.” Providers today are expected to integrate advanced technologies, foster flexible plant cultures, and navigate stringent regulatory landscapes, he notes. Essentially, O&M today functions both as a critical lever for optimizing performance and enabling grid reliability in an increasingly dynamic energy environment, but it must also simultaneously mitigate risks and seize opportunities, he says.

Tackling New O&M Challenges

According to Ricardo Guerrero, general manager for Global O&M at GE Vernova, O&M advancement varies by region. “It’s different in every part of the world, but I would say the main factor that is affecting O&M services at this moment is the penetration of renewables,” he says. Plunging costs for renewables have ushered in new operational demands for traditional thermal power plants, including combined cycle gas turbine (CCGT) power plants, which were historically designed as baseload workhorses. “Cycling is a big issue,” Guerrero acknowledges. “Cycling is associated with how you are going to react, how you are going to accommodate your team, how you are going to accommodate your strategy, your planning—everything associated to O&M services—to be really productive, take care of cost, and be efficient.”

Cost pressures amid inflation and market demand further compound these challenges. Power sector O&M costs typically fall into fixed costs and variable costs. Fixed costs cover consistent expenses like routine maintenance, staff salaries, and long-term equipment contracts, while variable costs fluctuate based on fuel prices, material needs, and unexpected repairs. Over the past five years, cost fluctuations have hinged emphatically on rising material costs for critical resources such as steel, copper, and silicon, with particular implications for aging thermal power plants that require frequent and costly repairs.

Table 1. A December 2023 U.S. Energy Information Administration (EIA) cost and performance survey conducted by Sargent & Lundy summarizes costs for most technologies, including overnight capital cost information, fixed operating and maintenance (O&M) costs, and variable non-fuel O&M costs. Notes: USC = ultrasupercritical; CTs = combustion turbines; CC = combined cycle; SS = single shaft; BFB = bubbling fluidized bed; MWAC = megawatt alternating current; WTG = wind turbine generator; BESS = battery energy storage system. Source: EIA, Capital Cost and Performance Characteristic Estimates for Utility Scale Electric Power Generating Technologies, January 2024.

Renewable O&M costs, while generally lower than those of thermal power plants, have been steadily decreasing due to technological advances, economies of scale, and experience-driven efficiencies. However, they remain sensitive to material price volatility and the growing demand for specialized maintenance services. Offshore wind, in particular, faces higher O&M costs compared to onshore wind, driven by logistical challenges, harsher environmental conditions, and the need for specialized vessels and remote monitoring systems. Meanwhile, costs for advanced technologies such as biomass and small modular reactors remain comparatively high. A cost and performance analysis conducted by engineering firm Sargent & Lundy compared 19 different technologies based on their capital and O&M costs (Table 1). Even as these emerging technologies promise operational efficiencies and decarbonization benefits over time, their high upfront investments and significant ongoing O&M expenses can pose serious feasibility challenges.

Enduring the Vast Realm of Policy and Regulatory Uncertainties

Still, the current power landscape is compelling more companies to adopt new technologies and approaches. A significant factor has been compliance with the evolving patchwork of government mandates, including regulations and incentives increasingly focused on accelerated decarbonization. The U.S. Environmental Protection Agency’s (EPA’s) April 2025–finalized Carbon Pollution Standards mandate carbon capture and sequestration (CCS) for existing coal units and new baseload combustion turbines, adding to rules regulating nitrogen oxides, mercury, effluent, and coal ash. Regional decarbonization differences and overlapping state-level policies are, meanwhile, creating additional complexity, driving operators to adopt tailored strategies to meet diverse compliance requirements.

Beyond emissions, regulations now also emphasize grid stability and reliability, compelling conventional generators to provide ancillary services such as fast frequency response and inertia. The need for resilience has also generally spurred mandates that require plants to bolster infrastructure to withstand extreme heat and cold events, floods, and droughts. Cybersecurity is another growing focus, with federal directives requiring power plants to implement stricter digital protections and incident reporting protocols.

“You must adapt to the market. If you don’t react, if you don’t change, if you don’t adjust yourself to the new conditions, you’re going to disappear,” notes GE Vernova’s Guerrero. GE Vernova’s approach has been to prepare customers for these transitions, including tailored maintenance strategies. “We take into account the specific operational stresses caused by renewables integration, ensuring that even older assets comply with regulatory thresholds while optimizing performance,” he explains.

Siemens Energy, a global provider of power technology, solutions, and services, shares a similar outlook. “Our O&M service is designed to manage and maintain various types of technology infrastructure or equipment. This approach is especially beneficial in diverse and complex operational settings such as carbon capture, where multiple types of technology coexist,” says Andrew Robson, Siemens Energy’s technical expert for O&M Solutions.

Best Practices for Maintenance in the Evolving Power World

While power plant maintenance is a cornerstone of reliable power generation, designing and maintaining an effective program will require careful consideration of modern challenges and strategies. Engineers at infrastructure solutions firm Gannett Fleming offer some pointers.

Understand Your Assets. Develop a detailed asset register to categorize and document critical assets, including electrical, mechanical, and civil infrastructure. Involve multidisciplinary experts to ensure a comprehensive understanding of maintenance needs.

Develop a Maintenance Strategy. Balance reactive, preventive, and predictive maintenance to address immediate needs while minimizing future risks. Document the rationale for each maintenance task based on regulatory requirements, manufacturer guidance, and risk analysis.

Leverage Technology. Invest in a computerized maintenance management system (CMMS) like Maximo or SAP CMMS to streamline scheduling, documentation, and data analysis, ensuring efficient resource allocation.

Stay Agile. Avoid static programs. Continuously assess and adapt maintenance strategies to reflect advancements in technology, changes in asset conditions, and best practices.

Prioritize Tasks. Prevent over-commitment by ranking maintenance activities based on risk to ensure critical tasks are executed effectively.

Address Challenges Holistically. Be wary of knee-jerk reactions to failures and aim for balanced solutions through root cause analysis and measured troubleshooting.

Foster Collaboration. Streamline decision-making by clearly defining roles while incorporating input from stakeholders to maintain agility in program updates.

“In the next decade, Siemens Energy will continue to offer expert O&M services to manage customer reliability risks, enhance efficiency, and centralize skills for consistent and reliable service supported by data-driven digital technologies,” Robson adds. While the need to decarbonize conventional power generation affects all utilities and is not specific to O&M, the company’s services “ensure that these technologies operate reliably and efficiently, contributing directly to meeting decarbonization goals,” he explains. Additionally, he underscores broader sustainability benefits, particularly through the use of a global network of remote operations and control centers. “Especially during COVID, it became clear that it is not always necessary to fly specialists around the world, but that a lot can be done remotely,” he says (see sidebar “Best Practices for Maintenance in the Evolving Power World”).

Solving the Workforce Puzzle

For now, experts agree the most urgent challenge facing the power sector is the shortage of skilled personnel. “O&M is all about people,” says Guerrero. “People tend to believe that in the future, power plants will be operated completely by robots, but we are really far away from that.” A key issue is that the workforce, traditionally the backbone of power plant operations, is aging, and with that comes the loss of decades of invaluable experience. “At the same time, we’re finding it increasingly difficult to attract younger talent, who are often drawn to tech-savvy industries like software and artificial intelligence [AI] rather than traditional fields like ours. It’s a problem we cannot afford to ignore because, without skilled workers, even the most advanced plants won’t function,” he says. To address these challenges, Guerrero explains that GE Vernova has developed structured knowledge-capture systems, including detailed playbooks created during contract mobilizations. “These are comprehensive guides that ensure when experienced team members retire or move on, their expertise doesn’t leave with them,” he says.

At the same time, GE Vernova, driven by its “lean” business philosophy, has already begun transitioning from traditional reliability-based maintenance approaches to more proactive, data-driven design-making enabled by AI and analytics. Guerrero said the company has developed autonomous robot technology capable of conducting inspections and identifying issues that human workers may miss. Demonstrating these technologies carries operational benefits, but a key intent is to transform the perception of O&M, positioning it as innovative, future-focused, and dynamic—attributes that could be attractive to a younger workforce, he says.

Robson echoes Guerrero’s concerns. “Even utilities with extensive experience in power plant operation and maintenance are now seeking our O&M expertise due to the skilled workforce shortage,” he notes. Siemens Energy’s approach has been to double down on technology. “Remote services are key to maintaining reliable operation and efficient maintenance,” says Robson, citing Siemens Energy’s 72-hour unmanned operation of the 300-MW Leipheim Power Plant in Germany (Figure 1). “Our remote monitoring centers handle routine monitoring and data analysis, freeing up experts for tasks that cannot yet be fully automated.”

According to Emily Obenauer, global director of Product Marketing at SiteTracker—a software-as-a-service platform that provides end-to-end asset lifecycle management—emerging tools are also set to play a transformative role in streamlining O&M operations with tangible workforce benefits. “Tools like ours are also shown to increase the satisfaction and increase the effectiveness of those workers out in the field because we’re getting so clear on what needs to be done and validating that that work has been done correctly the first time around,” she said.

Shoring Up Supply Chains

While workforce challenges have long afflicted the sector, more recent global supply disruptions are posing new concerns, prompting companies to reassess the resilience of their O&M operations. Siemens Energy’s Robson notes that, while temporary bottlenecks for parts and consumables remain a concern, “The shortage of people is, so to speak, the biggest bottleneck in the supply chain,” he says. He explains that most original equipment manufacturers (OEMs) proactively approach supply chain challenges to mitigate risks, leveraging global networks for flexibility. “We can access stock that was originally planned for other projects in the longer term. Additionally, close monitoring allows for the identification of required parts at an early stage as part of predictive maintenance,” he says.

2. To bolster its supply chain and prepare for increasing demand for its heavy-duty gas turbines and upgrades globally, GE Vernova moved in November 2025 to acquire Woodward Inc.’s combustion parts business in Greenville, South Carolina. This image shows a 7HA.03 gas turbine at GE Vernova’s own facility in Greenville, where it manufactures and tests gas turbines to provide global engineering support and other activities.

GE Vernova’s strategy is similar, entailing a proactive, collaborative approach with its customers (Figure 2). The company closely monitors its customers’ equipment and provides advance warning of potential failures. In addition, Guerrero says it helps customers pre-position critical spare parts to minimize downtime in the event of an issue. For example, when GE Vernova identified that the generators at a 20-year-old power plant in Taiwan were nearing the end of their life, it advised the customer to purchase a spare stator and rotor in advance. Two years later, the rotor failed, but because the spare part was already on-site, GE Vernova was able to quickly replace the rotor, getting the customer back online in just seven days, he says.

The Rise of Third-Party O&M Services

In another important trend, given modern complexities and evolving risks in the power sector, many utilities and power companies are increasingly turning to value-driven partnerships, often through third-party O&M service contracts. These partnerships encompass project management, robust training programs, detailed plant assessments, and the adoption of tailored best practices to optimize operations. Many are designed to leverage economies of scale and advanced remote operations, providing utilities with cost efficiencies and enhanced reliability in managing diverse energy assets.

“For many plant owners, O&M is no longer a core focus,” Guerrero explains. “Their priority is on generating and selling energy, which opens the door for third-party providers like us to step in with specialized expertise. But it’s not just about taking over operations—it’s about adding value. By leveraging performance-based contracts and advanced technologies, we focus on aligning our services with plant owners’ goals for reliability, efficiency, and profitability.” Guerrero notes that performance-based contracts are increasingly becoming a defining feature of third-party O&M services because they play a pivotal role in aligning incentives with plant reliability, availability, and efficiency. The contracts ensure accountability by incorporating measurable metrics, such as performance guarantees, and often include penalties for underperformance as well as rewards for exceeding targets. “This model ensures that everyone is focused on the same goal: maximizing the plant’s performance,” he says.

Global renewable energy developer Invenergy— a company known for its extensive portfolio of wind, solar, and storage projects—also highlighted the value proposition. The company says it approaches O&M services with an “owner’s mindset,” a philosophy that ensures top-tier maintenance practices and builds trust within their communities. “In addition to prioritizing safety, Invenergy Services’ other O&M pillars deliver benefits to customers through innovation, flexibility, and cost savings,” it says.

O&M’s Future: Tech and Sustainability

According to experts, the future of O&M in the power sector will be shaped by two transformative forces: technological innovation and the global push for sustainability. Already, as power generation grows more complex, modern O&M practices are increasingly integrating cutting-edge technologies like predictive analytics, autonomous systems, and maintenance strategies. “The future of operations and maintenance will heavily depend on integrating AI with digital tools to analyze data in real-time. This allows us to predict issues before they occur, saving costs and improving asset performance across the board,” says Guerrero.

Obenauer echoes this point. “We know that the future lies in digital transformation, and AI is a major focus. By applying AI to fieldwork and O&M processes, we’re already testing how to enhance efficiency and reliability while aligning with the workforce and industry needs.” AI-driven solutions also promise to unlock new opportunities in lifecycle management, she notes. “By centralizing asset data, companies can use AI to optimize resource allocation and focus on long-term asset health while navigating complex operational challenges.”

3. Operational since June 2023, the Kela PV Plant Phase 1, located in Sichuan Province, China, stands as one of the world’s largest hydro-solar hybrid power plants, combining 1 GW of solar capacity with the 3 GW Lianghekou Hydropower Plant. The site exemplifies advanced O&M practices in a challenging environment. Given that it is situated at an altitude of 4,600 meters, the plant endures extreme cold and high winds. Using a smart O&M platform with features like remote monitoring, automated fault detection, and real-time diagnostics, the plant minimizes manual intervention and ensures reliability. Courtesy: Huawei

On the other hand, sustainability will support the general charge toward cleaner energy sources, such as accommodating new technologies and hybrid configurations (Figure 3). Companies are exploring how to integrate emerging solutions such as hydrogen retrofits, thermal energy storage, and batteries into power plants, all while keeping costs low, maintaining reliability, and minimizing environmental impact.

As Guerrero stresses, a key takeaway is that O&M will need to be flexible and responsive rather than rigid. “You can navigate the sea as a cruise ship, or you can be a motorbike on the beach moving quick, and that’s the idea, that’s what we are doing,” he explains. Ultimately, proactivity will be necessary for nimble adaptation to keep pace with the changing landscape, he says.

biodiversity leaders for harris walz Conservation Science No Comments

On Thursday, September 26th, I spoke on a “Biodiversity Leaders for Harris-Walz” zoom call. This is the text of my remarks, including links to learn more.

Good evening. I’m Dr. David Shiffman, an ocean conservation scientist who studies threats to marine life and how we can solve those problems using wise evidence-based policymaking, through equitable processes in which everyone has a seat at the table. You can follow me on social media @ WhySharksMatter, where I’ll be sharing links to learn more about all of the issues I discuss here tonight.

The ocean connects and affects all Americans, but faces many threats, including climate change, habitat loss, pollution, and overfishing. Making the wrong policy choices here can have devastating ripple effects that last for generations, hurting coastal communities, costing countless jobs, and driving beloved species to extinction.

The Biden-Harris administration have been leaders in science-driven evidence-based policy for the ocean and coastal communities. They’ve committed the United States to the global goal of 30×30, fully protecting 30% of the ocean by the year 2030, and with the leadership of our amazing Secretary of the Interior Deb Haaland, have made huge progress accomplishing these important goals. In contrast, Donald Trump is the only US president in history to actually remove protections from a marine protected area, the Northeast Canyons and Seamounts Marine National Monument.

The Biden-Harris administration have also taken other important steps in protecting wildlife and wild places and sustainably managing natural resources, resulting in the first-ever National Nature Assessment, the first ever National Ocean Biodiversity Strategy, the first ever Ocean Acidification Action Plan, and many more documents that will be held up as exemplars of science-based environmental policymaking for years to come. They’ve created new National Marine Sanctuaries, and started the process of protecting nearly 700,000 square miles of ocean, an area 4 times the size of California in the Pacific Remote Island National Marine Monument. They’ve also invested billions in decarbonizing the transportation sector through the clean ports program. The Harris-Walz administration would continue these amazing and important strides.

In contrast, Project 2025, a blueprint for a second Trump administration, would be a disaster for the ocean, marine life, and coastal communities. Among other things, it calls for the total elimination of NOAA, the US government agency that houses the National Weather Service, the National Marine Fisheries Service who makes sure that US fisheries are sustainably managed, and many endangered species biologists who work to protect whales, coral reefs, sea turtles, and more. I have friends and family in Florida and am worried about Hurricane Helene, and cannot imagine if US citizens had to rely on a paid subscription to a private company to get severe weather alerts as Project 2025 calls for! Even the CEO of Accuweather says that’s a terrible idea! Project 2025 would also cripple the EPA, making it easier for wealthy companies to pollute our drinking water and food and air while causing incalculable harm to the marine environment. They’d also destroy progress made on protecting wildlife and wild places, and would eliminate the Antiquities Act, a powerful tool that allows US Presidents to protect new areas.

The choice here could not be more clear. To protect the ocean, coastal communities that depend on a healthy ocean, and beloved marine life, we must make sure that Donald Trump is not elected to a second term, and that Kamala Harris is elected. We are not going back.

Thank you.

Dunzo co-founder to join Walmart-owned Flipkart as startup looks for distress sale

Dunzo, the Indian hyperlocal delivery upstart backed by Google and Reliance, could see its last remaining founder — Kabeer Biswas — exit the company as well, reports MoneyControl. This comes amid reports suggesting Reliance’s potential write-off of its nearly $200Mn investment in the startup. Dunzo was valued at $1.2Bn at its peak, though is now reportedly up for sale in the vicinity of $50-70Mn.

The report suggests Biswas could join Walmart-owned Flipkart’s quick commerce arm, ‘Flipkart Minutes’, as Head of Operations. There is no clarity or confirmation received from Dunzo, Flipkart or Biswas himself. Biswas is likely to work closely with Hemant Badri, senior vice president (SVP) at Flipkart.

Dunzo’s rise and fall is reminiscent of what has happened to several other unicorn startups that India has produced in recent years. The startup, which started as a WhatsApp group, has raised over $400Mn across several funding rounds, from the likes of Google, Reliance, Blume Ventures and others. However, excessive cash burn, ignorance of key business fundamentals are some of the factors that led to the company shrinking in size significantly. Reports of the company delaying employee salaries started coming in from September of 2023, usually the first sign of a company sliding down.

Then further reports emerged in, suggesting Reliance — India’s largest public company by market cap, owned by billionaire Mukesh Ambani, had written off its entire investment in the company. Dunzo is now looking for buyers at a valuation, which is less than 1/20th of what it was valued at, during its fundraising spree.

diversity in science diversity in stem nasa pride Science space No Comments

Last June, a striking image of a pride flag made up of NASA imagery became the most-liked post on the new social media network Bluesky, a post it held for 2 months. I spoke with its creator Rachel Lense about how it was made, and what it’s reception means for inclusion in science.

This image was the most-shared on Bluesky from June to August 2024. Source

What is your role with NASA?

“My official title is Communications Lead for the Geospace Dynamics Constellation mission at NASA’s Goddard Space Flight Center. One of the aspects I love about my job is that I don’t have a “typical” day. Some days, I’m in meetings, listening to mission updates and scientists’ seminars, or collaborating with other comms folks on upcoming campaigns. Other days, I’m reading scientific papers, interviewing scientists about their work, and crafting articles or graphics. On some very special days, I’m fortunate enough to be out in the world, photographing rocket launches, helping with broadcasts, or engaging in public outreach.”

Tell me about the image you created and shared.

“The image I made and shared on social media include images from across NASA’s science divisions (Earth, Astrophysics, Planetary, and Heliophysics) to create a special space-themed version of the Progress Pride Flag designed by Daniel Quasar. My motivations were simply that: 1.) I love rainbows (colors make me ridiculously happy), 2.) I love space (and science in general), 3.) I love showing my own pride as part of the queer community as well as the pride I have working at a place where diversity of all kinds is not only embraced but celebrated. And I knew I wanted to include images from multiple science divisions at NASA to draw attention to the variety of work that’s done, too.”

How did you and your team make this image? Where did the source images come from?

“Open access to space research is one of the core foundations of NASA, and public engagement has been present and highly valued by the agency since its inception in 1958. (The cultural climate in which NASA was created is fascinating. Learn a little about the history here.) Imagery is a powerful tool we’ve successfully used over the decades to inspire generations to look beyond our everyday existence and learn more about our collective home in the universe.

As a NASA-inspired space-lover with a background in graphics, I’ve become familiar with a lot of our imagery over the years. I wanted to include some specific images in this Pride flag collage like Hubble’s staggering view into some of the earliest galaxies or the shot of Neptune Voyager 2 snagged as it flew past in 1989. But I found the rest of the images by searching for colors, learning about the different images from these searches, and deciding which ones would work well together and successfully communicate the breadth of science I wanted to display in the flag.

From there, I brought the selected images into Photoshop, created masks in the shapes of the Pride flag’s color bands, shifted them around a bit, and voila! — NASA Space Pride!

If folks want to learn more about each image used (and download a high-resolution version of the flag!), they can check out the Scientific Visualization Studio page here:”

The image quickly became the most-shared image in the history of BlueSky, so clearly it resonates with people. How did you expect it to be received on social media? How did it feel to have it be the most-shared image in the history of a whole social media platform?

“The main reason I shared the image on Bluesky was because I knew the community enjoys cool science and is queer affirming. And since NASA doesn’t have an official presence there, I decided to post it from my personal account on my own time. But I was certainly not prepared for the kind of attention it garnered.

As I mentioned to you when it was happening, David, I had to turn off notifications from all my social media apps because my phone was buzzing nonstop. I went through a period of intense anxiety (some people sent me threatening messages in different apps), but on the whole, the experience has been overwhelmingly positive.

One person shared photos of their home office with the space Pride flag printed on canvas right next to all their Hubble and James Webb prints. Another person used the image on a banner for their autistic inclusion group in the London Pride Parade. Someone from Brisbane said the city council is using it in dome shows and other public presentations. Daniel Quasar, the Progress Pride flag designer, even contacted me to tell me how much they loved it!

I think the message people all over the world are resonating with is this: Even the universe, in its terrible power and expansive beauty, is a spectrum of existence. We belong here. Everyone belongs here. After all, we’re made of star stuff, aren’t we?”

How can other people view/search NASA images?

“Gosh, I don’t think anyone knows how many images we have. NASA has flown hundreds of missions during its 65+ years of existence. Hubble alone has made over 1.6 million observations since it launched in April 1990. And there are other telescopes we work with that gather terabytes of information on a regular basis.

I will say, though, that the intersection of space data and data transport is fascinating. (It’s one of the big development focuses for AI and machine learning right now.) Recently, NASA tested some new technology using lasers to transfer pet photos and videos to spacecraft. (An ultra-high-definition video of Taters the cat was the first to be beamed across the solar system via laser last December. This made many internet denizens quite happy.)

But if you’re looking for casual NASA image perusing, I would recommend the following sites:

Is there anything else you’d like to say about this?

“Mostly, I want to say thank you.

Never in my life did I imagine something I created would touch literally millions of lives. It’s been heartening to see people respond to this image with such warmth, enthusiasm, and generosity. And even though it’s just a small thing — a colorful space image — I’m grateful it’s brought joy to so many.”
