Despite nuclear power’s unmatched ability to produce reliable, carbon-free energy at scale, it is often dismissed by clean energy advocates in favor of renewable resources like wind and solar. Cost arguments and public misconceptions around safety and radioactive waste have kept it out of many mainstream climate strategies. But as Tim Gregory argues in his new book Going Nuclear: How Atomic Energy Will Save the World, this exclusion may be the greatest obstacle to achieving net zero goals. In fact, Gregory says in his book “net zero is impossible without nuclear power.” “Claiming renewables on their own are enough to replace fossil fuels is underestimating the challenge of achieving net zero,” Gregory said as a guest on The POWER Podcast. “Fossil fuels have basically defined the world order for the last couple of centuries, and to think that we can replace them with wind power and solar power, which are fundamentally tied to the whims of the weather, and the rotation of the planet in the case of solar, is really underestimating the scale of the challenge,” he said. “We need power that comes in enormous quantities exactly where we need it and when we need it,” Gregory continued. “I don’t want to live in a world without solar panels or wind turbines, but to think that they can do it on their own, I think, is honestly naive. We need something that’s reliable to compensate for the intermittence of renewables, and nuclear power would be absolutely perfect for that.” Notably, innovative companies and many government leaders around the world are backing nuclear power projects. “Big tech in North America has really cottoned on to these small modular reactors,” said Gregory. “Meta, Google, Microsoft, and Amazon are all going to be using small modular reactors to power their data centers. … This isn’t just a pipe dream—this is actually happening now in real time. … It’s been very, very encouraging watching that unfold.” Public perceptions on nuclear power are also trending in a positive direction, and the movement seems to be bipartisan. “It’s very, very encouraging that more than half of people in the UK either strongly support or tend to support nuclear power. Strong opposition to nuclear power, according to the latest poll, is actually below 10%,” Gregory reported. “As such, the two major political parties in the UK—that’s the Labor Party, which is kind of our left leaning party, and the Conservative Party, which is our right leaning party—they both support the massive expansion of nuclear power, which is really, really nice actually. It’s maybe something that both sides of the political spectrum can agree on.” The same is true in the U.S., where both Democrats and Republicans have gotten behind nuclear power. A case in point is the Accelerating Deployment of Versatile, Advanced Nuclear for Clean Energy (ADVANCE) Act, which was signed into law in July 2024. It passed with overwhelming bipartisan support in the Senate with a vote of 88–2, and in the House of Representatives with a vote of 393–13. “If your politics has you more concerned with environmental stewardship, and climate change, and phasing out fossil fuels, and getting rid of oil from the energy system, then nuclear power is for you. But then at the same time, if your politics has you perhaps more leaning towards economic growth, and the economy, and prosperity, and all that kind of thing, then nuclear power is for you as well, because it provides the energy that enables that economic growth,” Gregory said. “And so, it’s actually very, very encouraging to see that, at least in most countries, nuclear power is not a partisan issue, which is all too rare in the world these days.”

More than 100 of the world’s largest energy companies are betting that artificial intelligence (AI) will revolutionize how electricity gets made, moved, and managed. But they’re not waiting for Silicon Valley to build it for them—they’ve taken matters into their own hands through an EPRI-led consortium. That initiative is the Open Power AI Consortium, which EPRI launched in March 2025 to drive the development and deployment of an open AI model tailored for the power sector. According to its mission statement, the Open Power AI Consortium “aims to evolve the electric sector by leveraging advanced AI technologies to innovate the way electricity is made, moved, and used by customers. By fostering collaboration among industry leaders, researchers, and technology providers, the consortium will drive the development and deployment of cutting-edge AI solutions tailored to enhance operational efficiencies, increase resiliency and reliability, deploy emerging and sustainable technologies, and reduce costs while improving the customer experience.” “We’re really looking at building an ecosystem to accelerate the development and deployment, and recognizing that, while AI is advancing rapidly, the energy industry has its own unique needs, especially around reliability, safety, regulatory compliance, and so forth. So, the consortium provides a collaborative platform to develop and maintain domain-specific AI models—think a ChatGPT tailored to the energy industry—as well as sharing best practices, testing innovative solutions in a secure environment, and long term, we believe this will help modernize the grid, improve customer experiences, and support global safe, affordable, and reliable energy for everyone,” Jeremy Renshaw, executive director for AI and Quantum with EPRI, said as a guest on The POWER Podcast. Among the consortium’s members are some of the largest energy companies in the world, including Constellation, Con Edison, Duke Energy, EDF, Korea Electric Power Corp. (KEPCO), New York Power Authority (NYPA), Pacific Gas and Electric Co. (PG&E), Saudi Electricity Co., Southern Company, Southern California Edison, Taiwan Power Co., and Tennessee Valley Authority (TVA). It also includes entities like Amazon Web Servies (AWS), Burns and McDonnell, GE Vernova, Google, Gulf Cooperation Council (GCC) Interconnection Authority, Korea Hydro and Nuclear Power (KHNP), Khalifa University, Microsoft, Midcontinent Independent System Operator (MISO), PJM, Rolls-Royce SMR, and Westinghouse Electric Co. “For many years, the power industry has been somewhat siloed, and there were not many touch points or communication between global utilities, technology companies, universities, and so forth. So, this consortium aims to facilitate making new connections between these important and impactful organizations to increase collaboration and information sharing that will benefit everyone,” Renshaw explained. EPRI, together with Articul8 and NVIDIA, has already developed the first set of domain-specific generative AI models for electric and power systems aimed at advancing the energy transformation. Although the technology has not been released publicly, it will be made available soon as an NVIDIA NIM microservice for early access. This development sets the foundation for more to come.

In a special edition of The POWER Podcast, released in collaboration with the McCrary Institute’s Cyber Focus podcast, POWER’s executive editor, Aaron Larson, and Frank Cilluffo, director of the McCrary Institute for Cyber and Critical Infrastructure Security and Professor of Practice at Auburn University, discuss the evolving power grid and cybersecurity challenges. Specifically, they highlight the shift taking place from centralized power stations to more distributed energy resources, including solar farms and wind turbines. The conversation touches on the importance of a reliable power grid and the need to protect critical infrastructure. “From a national security standpoint, from an economic standpoint, from a public safety standpoint, if you don’t have power, all these other systems are somewhat irrelevant,” Cilluffo said. “There’s no infrastructure more critical than power.” Cilluffo noted that artificial intelligence (AI) is requiring increasingly more power, which can’t be ignored. “If we want to be AI dominant, we can’t do that if we’re not energy dominant,” said Cilluffo. “The two are in inextricably interwoven—hand in glove. And if you start looking at where the country wants to be technologically, if we want to lead, we really need to continue to double down, triple down, and look at all sorts of sources of energy as well.” While renewables are clearly leading when it comes to new generation being added to the grid today, emerging technologies including small modular reactors, fusion power, deep dry-rock geothermal, and space-based solar power, are on the horizon, promising potentially game-changing energy options. “And not to put a fine point on it, but you mentioned so many different forms of energy, and I’m reminded of the old test, the A, B, C, or D, all of the above. This sounds like it is clearly an all of the above,” Cilluffo proposed. Meanwhile, the enormous energy buildout in China was discussed. China is not just leading, but truly dominating the world in the construction of wind, solar, nuclear, coal, and energy storage projects in 2025, both in terms of capacity and projects under development. This leadership is evident across all five sectors, frequently accounting for the majority, or at least a plurality, of new global construction and installation. “China is a primary focus of a lot of our [Cyber Focus] podcast discussion, but it’s a race we cannot afford to lose, whether it’s around AI, quantum. And, I think you’re spot on; to get there, they recognize the need to really quadruple down on energy,” said Cilluffo. “I still think that we [the U.S.] want to be at the vanguard driving all of this.” And while it’s widely known that cybersecurity is critically important to energy systems, it’s often not prioritized the way it should be. “Everyone needs to be cyber aware, cyber informed,” Cilluffo said. “These are issues that we have to invest in. It can’t be an afterthought. It has to be something that everyone thinks through. And the reality is, don’t think it’s someone else’s problem: a) it’s all of our problems, and b) don’t think that it can be looked at after the balloon goes up—you need to be thinking all of this well in advance.”

The name Mike Richter is well-known among hockey fans. Richter spent 15 years in the National Hockey League as a goalie for the New York Rangers, including in 1994 when he was a fixture in the net during the team’s Stanley Cup winning season. Richter was also recognized as the most valuable player for the U.S.’s 1996 gold medal winning World Cup team, as well as a member of three U.S. Olympic teams, including in 2002 when the team won the silver medal. Richter was inducted into the U.S. Hockey Hall of Fame in 2008. But what is likely lesser known is that Richter is the current president of Brightcore Energy, a leading provider of integrated, end-to-end clean energy solutions to the commercial, institutional, and government markets. The Armonk, New York–headquartered company’s services include high-efficiency geothermal-based heating and cooling systems for both new construction and existing building retrofits, among other things. Brightcore’s turnkey, single-point solution encompasses all project development phases including preliminary modeling, feasibility and design, incentive and policy guidance, construction and implementation, and system performance monitoring. As a guest on The POWER Podcast, Richter noted that heating, ventilation, and air conditioning (HVAC) systems for commercial, industrial, and municipal buildings consume an enormous amount of energy in a place like New York City. Furthermore, the emissions associated with these systems can be significant. “If you can address that, you’re doing something important, and that’s really where our focus has been, particularly the last few years,” he said. Geothermal Heating and Cooling Systems Traditional geothermal often requires significant open space for the geothermal borefield and can have material time implications in project development. Brightcore says its exclusive UrbanGeo solution combines proprietary geothermal drilling technology and techniques that increase the feasibility of geothermal heating and cooling applicability while reducing construction development timelines. “We typically go between 500 and 1,000 feet down,” Richter explained. “The ambient temperature of the ground about four feet down below our feet here in New York is 55 degrees [Fahrenheit] year-round.” The constant and stable underground temperature is the key to geothermal heating and cooling systems. Even when the air above ground is extremely hot or freezing cold, the earth’s steady temperature provides a valuable heating or cooling resource. A geothermal system has pipes buried underground that fluid is circulated through, and a heat pump inside the building. In winter, the fluid in the pipes absorbs warmth from the earth and brings it inside. There, the heat pump “compresses” this heat, raising its temperature so it can warm the building air comfortably—even when it’s icy cold outside. In summer, the system works in reverse. The heat pump pulls heat out of the building’s air, sending it through the same underground pipes. Since the earth is cooler than the hot summer air, it acts like a giant heat sponge, soaking up unwanted heat from the building. This process cools the living space easily and efficiently, using a lot less energy than a regular air conditioner because the ground is always cooler than the hot outdoor air. So, whether it’s heating or cooling, a geothermal system can keep buildings comfortable by moving heat between the building and the earth. “[It’s] pretty straightforward and very, very efficient and effective, particularly—and this is key—at the extremes,” said Richter. “Air source heat pumps are excellent and they continue to get better,” he added.

In the proverbial shadow of the Naughton Power Plant, a station in Kemmerer, Wyoming, that will stop burning coal at the end of this year, TerraPower is constructing what it calls “the only advanced, non-light-water reactor in the Western Hemisphere being built today.” The project represents more than just a new power source—it’s a symbolic passing of the torch from fossil fuels to next-generation nuclear technology. “We call it the Natrium reactor because it is in a class of reactors we call sodium fast reactors,” Eric Williams, Chief Operating Officer for TerraPower, said as a guest on The POWER Podcast. The Natrium design is a Generation IV reactor type, which is the most advanced class of reactors being developed today. “These designs have a greatly increased level of safety, performance, and economics,” Williams explained. Williams said the use of liquid metal coolant enhances safety. “Liquid metals are so excellent at transferring heat away from the reactor, both to exchange that heat into other systems to go generate the electricity or to remove the heat in an emergency situation,” he said. “For the Natrium reactor, we can do that heat removal directly to air if we want to, so that provides a very robust safety case for the reactor.” The design is also safer because it can run at low pressure. “The primary system is at atmospheric pressure; whereas, current pressurized water reactors have to pressurize the system to keep the liquid from boiling—to keep it in a liquid state,” Williams explained. “Liquid metal sodium doesn’t boil until about 800 to 900 degrees Celsius, and the reactor operates down at 500 degrees Celsius, so that can remain a liquid and still be at a very high temperature without having to pressurize it.” The liquid metal coolant also provides performance benefits. “One of those is the ability to store the energy in the form of molten salt heat coming out of the nuclear island,” said Williams. “That is really giving us the ability to provide basically a grid-scale energy storage solution, and it really matches up well with the current needs of the modern electricity grid.” Meanwhile, the energy storage aspect also allows decoupling the electricity generation side of the plant—the energy island—from the reactor side of the plant, that is, the nuclear island. That allows the energy island to be classified as “non-safety-related” in the eyes of the U.S. Nuclear Regulatory Commission (NRC). “That side of the plant has nothing to do with keeping the reactor safe, and that means the NRC oversight doesn’t have to apply to the energy island side of the plant, so all of that equipment can be built to lower cost and different codes and standards,” Williams explained. Notably, this also permits the grid operator to dispatch electricity without changing anything on the nuclear island. “That allows a different kind of integrating with the grid for a nuclear plant that hasn’t been achieved yet in the U.S.,” Williams said. “We’re very excited about that—the safety, the performance, and economics—and it really gives us the ability to have a predictable schedule, and construction will be complete in 2030.” While there is clearly a lot that needs to be done, and first-of-a-kind projects rarely go off without a hitch, Williams seemed pleased with how the project was progressing. “We’re really excited to be working in the state of Wyoming. It is just an outstanding state for developing any kind of energy project, including nuclear energy. The people in the community are really welcoming to us. The state legislators are always looking for ways to remove any obstacles and just explain to us how to get the permits we need and everything. So, the project has been going really well from that standpoint,” he said. In the end, Williams appeared confident that TerraPower would hit its current target for completion in 2030.

The world’s electricity grids are facing unprecedented strain as demand surges from electrification, data centers, and renewable energy integration, while aging infrastructure struggles to keep pace. Traditional approaches to grid expansion—building new transmission lines and substations—face mounting challenges including sometimes decade-long permitting processes, escalating costs that can reach billions per project, and growing public resistance to new infrastructure. This mounting pressure has created an urgent need for innovative solutions that can unlock the hidden capacity already embedded within existing transmission networks. What Are GETs and What Do They Do? Grid enhancing technologies (GETs) represent a transformative approach to this challenge, offering utilities the ability to safely increase power flows on existing transmission lines by up to 40% in some cases without the need for new construction. These advanced technologies—including dynamic line ratings (DLR) that adjust capacity based on real-time weather conditions, high-temperature advanced conductors that can carry significantly more current, and sophisticated power flow controllers that optimize electricity routing—work by maximizing the utilization of current infrastructure. Rather than building around bottlenecks, GETs eliminate them through smarter, more responsive grid management. On an episode of The POWER Podcast, Anna Lafoyiannis, program lead for the integration of renewables and co-lead of the GET SET (Grid Enhancing Technologies for a Smart Energy Transition) initiative with EPRI, explained that GETs can be either hardware or software solutions. “Their purpose is to increase the capacity, efficiency, reliability, or safety of transmission lines. So, think of these as adders to your transmission lines to make them even better,” Lafoyiannis said. “Typically, they reduce congestion costs. They improve the integration of renewables. They increase capacity. They can provide grid service applications. So, they’re really multifaceted—very helpful for the grid,” she said. “At EPRI, we think of them as kind of like a tool in a toolbox.” The economic and environmental implications are profound. Deploying GETs can defer or eliminate the need for costly new transmission projects while accelerating the integration of renewable energy resources that are often stranded due to transmission constraints. As utilities worldwide grapple with the dual pressures of modernizing their grids and meeting ambitious clean energy targets, GETs offer a compelling path forward that leverages innovation over infrastructure expansion to create a more resilient, efficient, and sustainable electricity system.

As the world transitions toward renewable energy sources, geothermal power has emerged as one of the most promising, yet underutilized, options in the clean energy portfolio. Unlike solar and wind, geothermal offers consistent baseload power generation capacity without intermittency challenges, making it an increasingly attractive component in the renewable energy mix. The geothermal sector has shown increasing potential in recent years, with technological innovations expanding its possible applications beyond traditional volcanic regions. These advances are creating opportunities to tap into moderate-temperature resources that were previously considered uneconomical, potentially unlocking gigawatts of clean, renewable power across the globe. It's within this expanding landscape that companies like Gradient Geothermal are pioneering new approaches. As a guest on The POWER Podcast, Ben Burke, CEO of Gradient Geothermal, outlined his company’s innovative approach to geothermal energy extraction that could transform how we think about energy recovery from oil and gas operations. Modular and Mobile Geothermal Solutions Gradient Geothermal differentiates itself in the geothermal marketplace through its focus on modular, portable equipment designed specifically for oil field operations, geothermal operators, and potentially data centers. Unlike traditional geothermal installations that require permanent infrastructure, Gradient’s equipment can be moved every six to 18 months as needed, allowing clients to adjust their thermal capacity by adding or removing units as requirements change. “The advantage of mobility and modularity is really important to oil and gas operators,” Burke said. The company’s solution consists of two main components: an off-the-shelf organic Rankine cycle (ORC) unit and a primary heat exchanger loop. This system can handle various ratios of oil, gas, and water—even “dirty” water containing sand, brines, and minerals—and convert that heat into usable power. One of the most compelling aspects of Gradient’s technology is its ease of installation. “Installation takes one day,” Burke explained. “It’s two pipes and three wires, and it’s able to sit on a gravel pad or sit on trailers.” This quick setup contrasts sharply with traditional geothermal plants that can take years to construct. The units come in three sizes: 75 kW, 150 kW, and 300 kW. The modular nature allows for flexible configurations, with units able to be connected in series or parallel to handle varying water volumes and temperatures.

U.S. President Donald Trump was sworn into office for the second time on Jan. 20, 2025. That means April 30 marks his 100th day back in office. A lot has happened during that relatively short period of time. The Trump administration has implemented sweeping changes to U.S. energy policy, primarily focused on promoting fossil fuels while curtailing renewable energy development. The administration declared a “national energy emergency” to expedite approvals for fossil fuel infrastructure and lifted regulations on coal plants, exempting nearly 70 facilities from toxic pollutant rules. Coal was officially designated a “critical mineral,” with the Department of Justice directed to investigate regulatory bias against the industry. Additionally, the administration ended the Biden-era pause on approvals for new liquefied natural gas (LNG) export facilities, signaling strong support for natural gas expansion. On the environmental front, U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin announced 31 deregulatory actions designed in part to “unleash American energy.” The administration is also challenging the 2009 EPA finding that greenhouse gases endanger public health—a foundational element of climate regulation. President Trump announced the U.S.’s withdrawal from the Paris Climate Agreement, effective in early 2026, and terminated involvement in all climate-related international agreements, effectively eliminating previous emissions reduction commitments. Renewable energy has faced significant obstacles under the new administration. A six-month pause was imposed on offshore wind lease sales and permitting in federal waters, with specific projects targeted for cancellation. The administration issued a temporary freeze on certain Inflation Reduction Act (IRA) and Bipartisan Infrastructure Law (BIL) funds designated for clean energy projects. Policies were implemented to weaken federal clean car standards, potentially eliminate electric vehicle (EV) tax credits, and halt funding for EV charging networks—indirectly affecting power generation by potentially reducing electricity demand from EVs. Yet, the administration’s tariff policy may end up impacting the power industry more than anything else it has done. “One thing in particular that I think would be hard to argue is not the most impactful, and that’s the current status of tariffs and a potential trade war,” Greg Lavigne, a partner with the global law firm Sidley Austin, said as a guest on The POWER Podcast. In April, President Trump declared a national emergency to address trade deficits, imposing a 10% tariff on all countries and higher tariffs on nations with large trade deficits with the U.S. These tariffs particularly affect solar panels and components from China, potentially increasing costs for renewable energy projects and disrupting supply chains. Meanwhile, the offshore wind energy industry has also taken a hard hit under the Trump administration. “My second-biggest impact in the first 100 days would certainly be the proclamations pausing evaluation of permitting of renewable projects, but particularly wind projects, on federal lands,” said Lavigne. “That is having real-world impacts today on the offshore wind market off the eastern seaboard of the United States.” Despite the focus on traditional energy sources, the Trump administration has expressed support for nuclear energy as a tool for energy dominance and global competitiveness against Russian and Chinese nuclear exports. Key appointees, including Energy Secretary Chris Wright, have signaled a favorable stance toward nuclear power development, including small modular reactors. All these actions remain subject to ongoing legal and political developments, with their full impact on the power generation industry yet to unfold.

The power industry supply chain is facing unprecedented strain as utilities race to upgrade aging infrastructure against a backdrop of lengthening lead times and increasing project complexity. This supply chain gridlock arrives precisely when utilities face mounting pressure to modernize systems. As the industry confronts this growing crisis, innovations in procurement, manufacturing, and strategic planning are essential. “Utilities can optimize their supply chain for grid modernization projects by taking a collaborative approach between the services themselves and how they can support the projects, as well as having a partner to be able to leverage their sourcing capabilities and have the relationships with the right manufacturers,” Ian Rice, senior director of Programs and Services for Grid Services at Wesco, explained as a guest on The POWER Podcast. “At the end of the day, it’s how can the logistical needs be accounted for and taken care of by the partnered firm to minimize the overall delays that are going to naturally come and mitigate the risks,” he said. Headquartered in Pittsburgh, Pennsylvania, Wesco is a leading global supply chain solutions provider. Rice explained that through Wesco, utilities gain access to a one-stop solution for program services, project site services, and asset management. The company claims its tailored approach “ensures cost reduction, risk mitigation, and operational efficiencies, allowing utilities to deliver better outcomes for their customers.” “We take a really comprehensive approach to this,” said Rice. “In the utility market, we believe pricing should be very transparent.” To promote a high level of transparency, Wesco builds out special recovery models for its clients. “What this looks like is: we take a complete cradle-to-grave approach on the lifecycle of the said project or program, and typically, it could be up to nine figures—very, very large programs,” Rice explained. “It all starts with building that model and understanding the complexity. What are the inputs, what are the outputs, and what constraints are there in the short term as well as the long term? And, really, what’s the goal of that overall program?” The answers to those questions are accounted for in the construction of the model. “It all starts with demand management, which closely leads to a sourcing and procurement strategy,” Rice said. “From there, we can incorporate inventory control, and set up SOPs [standard operating procedures] of how we want to deal with the contractors and all the other stakeholders within that program or project. And that really ties into what’s going to be the project management approach, as well in setting up all the different processes, or even the returns and reclamation program. We’re really covering everything minute to minute, day to day, the entire duration of that project, and tying that into a singular model.” But that’s not all. Rice said another thing that sets Wesco apart from others in the market is when it takes this program or project approach, depending on the scale of it, the company remains agnostic when it comes to suppliers. “We’re doing procurement on behalf of our customers,” he said. “So, if they have direct relationships, we can facilitate that. If they’re working with other distributors, we can also manage that. The whole idea here is: what’s in the best interest of the customer to provide the most value.”

As the presidential inauguration loomed on the horizon in January this year, the U.S. Department of Energy’s (DOE’s) Loan Programs Office (LPO) published a “year-in-review” article, highlighting accomplishments from 2024 and looking ahead to the future. It noted that the previous four years had been the most productive in the LPO’s history. “Under the Biden-Harris Administration, the Office has announced 53 deals totaling approximately $107.57 billion in committed project investment––approximately $46.95 billion for 28 active conditional commitments and approximately $60.62 billion for 25 closed loans and loan guarantees,” it said. Much of the funding for these investments came through the passing of the Bipartisan Infrastructure Law (BIL) and the Inflation Reduction Act (IRA). The LPO reported that U.S. clean energy investment more than doubled from $111 billion in 2020 to $236 billion in 2023, creating more than 400,000 clean energy jobs. The private sector notably led the way, enabled by U.S. government policy and partnerships. “There were 55 deals that we got across the finish line,” Jigar Shah, director of the LPO from March 2021 to January 2025, said as a guest on The POWER Podcast, while noting there were possibly 200 more projects that were nearly supported. “They needed to do more work on their end to improve their business,” he explained. That might have meant they needed to de-risk their feedstock agreement or their off-take agreement, for example, or get better quality contractors to do the construction of their project. “It was a lot of education work,” Shah said, “but I’m really proud of that work, because I think a lot of those companies, regardless of whether they used our office or not, were better for the interactions that they had with us.” A Framework for Success When asked about doling out funds, Shah viewed the term somewhat negatively. “As somebody who’s been an investor in my career, you don’t dole out money, because that’s how you lose money,” he explained. “What you do is you create a framework. And you tell people, ‘Hey, if you meet this framework, then we’ve got a loan for you, and if you don’t meet this framework, then we don’t have a loan for you.” Shah noted that the vast majority of the 400 to 500 companies that the LPO worked closely with during his tenure didn’t quite meet the framework. Still, most of those that did have progressed smoothly. “Everything that started construction is still under construction, and so, they’re all going to be completed,” said Shah. “I think all in all, the thesis worked. Certainly, there are many people who had a hard time raising equity or had a hard time getting to the finish line and final investment decision, but for those folks who got to final investment decision and started construction, I think they’re doing very well.” Notable Projects When asked which projects he was most excited about, Shah said, “All of them are equally exciting to me. I mean, that’s the beauty of the work I do.” He did, however, go on to mention several that stood out to him. Specifically, he pointed to the Wabash, Montana Renewables, EVgo, and Holtec Palisades projects, which were all supported under the LPO’s Title 17 Clean Energy Financing Program, as particularly noteworthy. Perhaps the most important of the projects Shah mentioned from a power industry perspective, was the Holtec Palisades endeavor. Valued at $1.52 billion, the loan guarantee will allow upgrading and repowering of the Palisades nuclear plant in Covert, Michigan, a first in U.S. history, which has spurred others to bring retired nuclear plants back online. “[It’s] super exciting to see our first nuclear plant being restarted, and as a result, the Constellation folks have decided to restart a nuclear reactor in Pennsylvania, and NextEra has decided to restart a nuclear reactor in Iowa. So, it’s great to have that catalytic impact,” said Shah.

The Tennessee Valley Authority (TVA) has for many years been evaluating emerging nuclear technologies, including small modular reactors, as part of technology innovation efforts aimed at developing the energy system of the future. TVA—the largest public power provider in the U.S., serving more than 10 million people in parts of seven states—currently operates seven reactors at three nuclear power plants: Browns Ferry, Sequoyah, and Watts Bar. Meanwhile, it’s also been investing in the exploration of new nuclear technology by pursuing small modular reactors (SMRs) at the Clinch River Nuclear (CRN) site in Tennessee. “TVA does have a very diverse energy portfolio, including the third-largest nuclear fleet [in the U.S.],” Greg Boerschig, TVA’s vice president for the Clinch River project, said as a guest on The POWER Podcast. “Our nuclear power plants provide about 40% of our electricity generated at TVA. So, this Clinch River project and our new nuclear program is building on a long history of excellence in nuclear at the Tennessee Valley.” TVA completed an extensive site selection process before choosing the CRN site as the preferred location for its first SMR. The CRN site was originally the site of the Clinch River Breeder Reactor project in the early 1980s. Extensive grading and excavation disturbed approximately 240 acres on the project site before the project was terminated. Upon termination of the project, the site was redressed and returned to an environmentally acceptable condition. The CRN property is approximately 1,200 acres of land located on the northern bank of the Clinch River arm of the Watts Bar Reservoir in Oak Ridge, Roane County, Tennessee. The CRN site has a number of significant advantages, which include two existing power lines that cross the site, easy access off of Tennessee State Route 58, and the fact that it is a brownfield site previously disturbed and characterized as a part of the Clinch River Breeder Reactor project. The Oak Ridge area is also noted to have a skilled local workforce, including many people familiar with the complexities of nuclear work. “The community acceptance here is really just phenomenal,” said Boerschig. “The community is very educated and very well informed.” TVA began exploring advanced nuclear technologies in 2010. In 2016, it submitted an application to the Nuclear Regulatory Commission (NRC) for an Early Site Permit for one or more SMRs with a total combined generating capacity not to exceed 800 MW of electricity for the CRN site. In December 2019, TVA became the first utility in the nation to successfully obtain approval for an Early Site Permit from the NRC to potentially construct and operate SMRs at the site. While the decision to potentially build SMRs is an ongoing discussion as part of the asset strategy for TVA’s future generation portfolio, significant investments have been made in the Clinch River project with the goal of moving it forward. OPG has a BWRX-300 project well underway at its Darlington New Nuclear Project site in Clarington, Ontario, with construction expected to be complete by the end of 2028. While OPG is developing its project in parallel with the design process, TVA expects to wait for more design maturity before launching its CRN project. “As far as the standard design is concerned, we’re at the same pace, but overall, their project is about two years in front of ours,” said Boerschig. “And that’s by design—they are the lead plant for this effort.” In the meantime, there are two primary items on TVA’s to-do list. “Right now, the two biggest things that we have on our list are completing the standard design work, and then the construction permit application,” Boerschig said, noting the standard design is “somewhere north of 75% complete” and that TVA’s plan is to submit the construction permit application “sometime around mid-year of this year.”

A virtual power plant (VPP) is a network of decentralized, small- to medium-scale power generating units, flexible power consumers, and storage systems that are aggregated and operated as a single entity through sophisticated software and control systems. Unlike a traditional power plant that exists in a single physical location, a VPP is distributed across multiple locations but functions as a unified resource. VPPs are important to power grid operations because they provide grid flexibility. VPPs help balance supply and demand on the grid by coordinating many smaller assets to respond quickly to fluctuations. This becomes increasingly important as more intermittent renewable energy sources—wind and solar—are added to the grid. “A virtual power plant is essentially an aggregation of lots of different resources or assets from the grid,” Sally Jacquemin, vice president and general manager of Power & Utilities with AspenTech, said as a guest on The POWER Podcast. “As a whole, they have a bigger impact on the grid than any individual asset would have on its own. And so, you aggregate all these distributed energy resources and assets together to create a virtual power plant that can be dispatched to help balance the overall system supply to demand.” VPPs provide a way to effectively integrate and manage distributed energy resources such as rooftop solar, small wind turbines, battery storage systems, electric vehicles, and demand response programs. VPPs can reduce strain on the grid during peak demand periods by strategically reducing consumption or increasing generation from distributed sources, helping to avoid blackouts and reducing the need for expensive peaker plants. Other benefits provided by VPPs include enhancing grid resilience, enabling smaller energy resources to participate in electricity markets that would otherwise be inaccessible to them individually, and reducing infrastructure costs by making better use of existing assets and reducing peak demand. VPPs enable consumers to become “prosumers,” that is, both producers and consumers of energy, giving them more control over their energy use and potentially reducing their costs. “Virtual power plants are becoming important, not only for utilities, but also in the private sector,” Jacquemin explained. “Because of the commercial value of electricity rising and the market system rates, it’s now profitable for these virtual power plants in many markets due to the value of power that they can supply during these periods of low supply.” AspenTech is a leading industrial software partner, with more than 60 locations worldwide. The company’s solutions address complex environments where it is critical to optimize the asset design, operation, and maintenance lifecycle. AspenTech says its Digital Grid Management solutions “enable the resilient, sustainable, and intelligent utility of the future.” “At AspenTech Digital Grid Management, our software is in control rooms of utilities around the world,” said Jacquemin. “All utilities know they need to be investing in their digital solutions and modernizing their control room technology in order to meet the demands of the energy transition. So, utilities need to be focusing more time and more money to ensure that their software and their systems are capable of enabling that utility of the future.”

Net-demand energy forecasts are critical for competitive market participants, such as in the Electric Reliability Council of Texas (ERCOT) and similar markets, for several key reasons. For example, accurate forecasting helps predict when supply-demand imbalances will create price spikes or crashes, allowing traders and generators to optimize their bidding strategies. It’s also important for asset optimization. Power generators need to know when to commit resources to the market and at what price levels. Poor forecasting can lead to missed profit opportunities or operating assets when prices don’t cover costs. Fortunately, artificial intelligence (AI) is now capable of producing highly accurate forecasts from the growing amount of meter and weather data that is available. The complex and robust calculations performed by these machine-learning algorithms is well beyond what human analysts are capable of, making advance forecasting systems essential to utilities. Plus, they are increasingly valuable to independent power producers (IPPs) and other energy traders making decisions about their positions in the wholesale markets. Sean Kelly, co-founder and CEO of Amperon, a company that provides AI-powered forecasting solutions, said using an Excel spreadsheet as a forecasting tool was fine back in 2005 when he got started in the business as a power trader, but that type of system no longer works adequately today. “Now, we’re literally running at Amperon four to six models behind the scenes, with five different weather vendors that are running an ensemble each time,” Kelly said as a guest on The POWER Podcast. “So, as it gets more confusing, we’ve got to stay on top of that, and that’s where machine learning really kicks in.” The consequences of being ill-prepared can be dire. Having early and accurate forecasts can mean the difference between a business surviving or failing. Effects from Winter Storm Uri offer a case in point. Normally, ERCOT wholesale prices fluctuate from about $20/MWh to $50/MWh. During Winter Storm Uri (Feb. 13–17, 2021), ERCOT set the wholesale electricity price at its cap of $9,000/MWh due to extreme demand and widespread generation failures caused by the storm. This price remained in effect for approximately 4.5 days (108 hours). This 180-fold price increase had devastating financial impacts across the Texas electricity market. The financial fallout was severe. Several retail electricity providers went bankrupt, most notably Griddy Energy, which passed the wholesale prices directly to customers, resulting in some receiving bills of more than $10,000 for just a few days of power. “Our clients were very appreciative of the work we had at Amperon,” Kelly recalled. “We probably had a dozen or so clients at that time, and we told them on February 2 that this was coming,” he said. With that early warning, Kelly said Amperon’s clients were able to get out in front of the price swing and buy power at much lower rates. “Our forecasts go out 15 days, ERCOT’s forecasts only go out seven,” Kelly explained. “So, we told everyone, ‘Alert! Alert! This is coming!’ Dr. Mark Shipham, our in-house meteorologist, was screaming it from the rooftops. So, we had a lot of clients who bought $60 power per megawatt. So, think about buying 60s, and then your opportunity is 9,000. So, a lot of traders made money,” he said. “All LSEs—load serving entities—still got hit extremely bad, but they got hit a lot less bad,” Kelly continued. “I remember one client saying: ‘I bought power at 60, then I bought it at 90, then I bought it at 130, then I bought it at 250, because you kept telling me that load was going up and that this was getting bad.’ And they’re like, ‘That is the best expensive power I’ve ever bought. I was able to keep my company as a retail energy provider.’ And, so, those are just some of the ways that these forecasts are extremely helpful.”

When you think of innovative advancements in nuclear power technology, places like the Idaho National Laboratory and the Massachusetts Institute of Technology probably come to mind. But today, some very exciting nuclear power development work is being done in West Texas, specifically, at Abilene Christian University (ACU). That’s where Natura Resources is working to construct a molten salt–cooled, liquid-fueled reactor (MSR). “We are in the process of building, most likely, the country’s first advanced nuclear reactor,” Doug Robison, founder and CEO of Natura Resources, said as a guest on The POWER Podcast. Natura has taken an iterative, milestone-based approach to advanced reactor development and deployment, focused on efficiency and performance. This started in 2020 when the company brought together ACU’s NEXT Lab with Texas A&M University; the University of Texas, Austin; and the Georgia Institute of Technology to form the Natura Resources Research Alliance. In only four years, Natura and its partners developed a unique nuclear power system and successfully licensed the design. The U.S. Nuclear Regulatory Commission (NRC) issued a construction permit for deployment of the system at ACU last September. Called the MSR-1, ACU’s unit will be a 1-MWth molten salt research reactor (MSRR). It is expected to provide valuable operational data to support Natura’s 100-MWe systems. It will also serve as a “world-class research tool” to train advanced reactor operators and educate students, the company said. Natura is not only focused on its ACU project, but it is also moving forward on commercial reactor projects. In February, the company announced the deployment of two advanced nuclear projects, which are also in Texas. These deployments, located in the Permian Basin and at Texas A&M University’s RELLIS Campus, represent significant strides in addressing energy and water needs in the state. “Our first was a deployment of a Natura commercial reactor in the Permian Basin, which is where I spent my career. We’re partnering with a Texas produced-water consortium that was created by the legislature in 2021,” said Robison. One of the things that can be done with the high process heat from an MSR is desalinization. “So, we’re going to be desalinating produced water and providing power—clean power—to the oil and gas industry for their operations in the Permian Basin,” said Robison. Meanwhile, at Texas A&M’s RELLIS Campus, which is located about eight miles northwest of the university’s main campus in College Station, Texas, a Natura MSR-100 reactor will be deployed. The initiative is part of a broader project known as “The Energy Proving Ground,” which involves multiple nuclear reactor companies. The project aims to bring commercial-ready small modular reactors (SMRs) to the site, providing a reliable source of clean energy for the Electric Reliability Council of Texas (ERCOT).

Geothermal energy has been utilized by humans for millennia. While the first-ever use may be a mystery, we do know the Romans tapped into it in the first century for hot baths at Aquae Sulis (modern-day Bath, England). Since then, many other people and cultures have found ways to use the Earth’s underground heat to their benefit. Geothermal resources were used for district heating in France as far back as 1332. In 1904, Larderello, Italy, was home to the world’s first experiment in geothermal electricity generation, when five lightbulbs were lit. By 1913, the first commercial geothermal power plant was built there, which expanded to power the local railway system and nearby villages. However, one perhaps lesser-known geothermal concept revolves around energy storage. “It’s very much like pumped-storage hydropower, where you pump a lake up a mountain, but instead of going up a mountain, we’re putting that lake deep in the earth,” Cindy Taff, CEO of Sage Geosystems, explained as a guest on The POWER Podcast. Sage Geosystems’ technology utilizes knowledge gleaned from the oil and gas industry, where Taff spent more than 35 years as a Shell employee. “What we do is we drill a well. We’re targeting a very low-permeability formation, which is the opposite of what oil and gas is looking for, and quite frankly, it’s the opposite of what most geothermal technologies are looking for. That low permeability then allows you to place a fracture in that formation, and then operate that fracture like a balloon or like your lungs,” Taff explained. “When the demand is low, we use electricity to power an electric pump. We pump water into the fracture. We balloon that fracture open and store the water under pressure until a time of day that power demand peaks. Then, you open a valve at surface. That fracture is naturally going to close. It drives the water to surface. You put it through a Pelton turbine, which looks like a kid’s pinwheel. You spin the turbine, which spins the generator, and you generate electricity.” Unlike more traditional geothermal power generation systems that use hot water or steam extracted from underground geothermal reservoirs, Sage’s design uses what’s known as hot dry rock technology. To reach hot dry rock, drillers may have to go deeper to find desired formations, but these formations are much more common and less difficult to identify, which greatly reduces exploration risks. Taff said traditional geothermal energy developers face difficulties because they need to find three things underground: heat, water, and high-permeability formations. “The challenge is the exploration risk, or in other words, finding the resource where you’ve got the heat, the large body of water deep in the earth, as well as the permeability,” she said. “In hot dry rock geothermal, which is what we’re targeting, you’re looking only for that heat. We want a low-permeability formation, but again, that’s very prevalent.” Sage is now in the process of commissioning its first commercial energy storage project in Texas. “We’re testing the piping, and we’re function testing the generator and the Pelton turbine, so we’ll be operating that facility here in the next few weeks,” Taff said. Meanwhile, the company has also signed an agreement with the California Resources Corporation to establish a collaborative framework for pursuing commercial projects and joint funding opportunities related to subsurface energy storage and geothermal power generation in California. It also has ongoing district heating projects in Lithuania and Romania, and Taff said the U.S. Department of Defense has shown a lot of interest in the company’s geothermal technology. Additionally, Meta signed a contract for a 150-MW geothermal power generation system to supply one of its data centers.

Imagine a field of solar panels floating silently in the endless day of Earth’s orbit. Unlike their terrestrial cousins, this space-based solar array never faces nighttime, clouds, or atmospheric interference. Instead, they bathe in constant, intense sunlight, converting this endless stream of energy into electricity with remarkable efficiency. But the true innovation lies in how this power is transmitted to power grids on Earth. The electricity generated in space is converted into invisible beams of microwaves or laser light that pierce through the atmosphere with minimal losses. These beams are precisely aimed at receiving stations on Earth—collections of antennas or receivers known as “rectennas” that capture and reconvert the energy back into electricity that can be supplied to the power grid. This isn’t science fiction—it’s space-based solar power (SBSP), a technology that could revolutionize how clean energy is generated and distributed. While conventional solar panels on Earth can only produce power during daylight hours and are at the mercy of weather conditions, orbital solar arrays could beam massive amounts of clean energy to Earth 24 hours a day, 365 days a year, potentially transforming the global energy landscape.

Power grids operate like an intricate ballet of energy generation and consumption that must remain perfectly balanced at all times. The grid maintains a steady frequency (60 Hz in North America and 50 Hz in many other regions) by matching power generation to demand in real-time. Traditional power plants with large rotating turbines and generators play a crucial role in this balance through their mechanical inertia—the natural tendency of these massive spinning machines to resist changes in their rotational speed. This inertia acts as a natural stabilizer for the grid. When there’s a sudden change in power demand or generation, such as a large factory turning on or a generator failing, the rotational energy stored in these spinning masses automatically helps cushion the impact. The machines momentarily speed up or slow down slightly, giving grid operators precious seconds to respond and adjust other power sources. However, as we transition to renewable energy sources like solar and wind that don’t have this natural mechanical inertia, maintaining grid stability becomes more challenging. This is why grid operators are increasingly focusing on technologies like synthetic inertia from wind turbines, battery storage systems, and advanced control systems to replicate the stabilizing effects traditionally provided by conventional power plants. Alex Boyd, CEO of PSC, a global specialist consulting firm working in the areas of power systems and control systems engineering, believes the importance of inertia will lessen, and probably sooner than most people think. In fact, he suggested stability based on physical inertia will soon be the least-preferred approach. Boyd recognizes that his view, which was expressed while he was a guest on The POWER Podcast, is potentially controversial, but there is a sound basis behind his prediction. Power electronics-based systems utilize inverter-based resources, such as wind, solar, and batteries. These systems can detect and respond to frequency deviations almost instantaneously using fast frequency response mechanisms. This actually allows for much faster stabilization compared to mechanical inertia. Power electronics reduce the need for traditional inertia by enabling precise control of grid parameters like frequency and voltage. While they decrease the available physical inertia, they also decrease the amount of inertia required for stability through advanced control strategies. Virtual synchronous generators and advanced inverters can emulate inertia dynamically, offering tunable responses that adapt to grid conditions. For example, adaptive inertia schemes provide high initial inertia to absorb faults but reduce it over time to prevent oscillations. Power electronic systems address stability issues across a wide range of frequencies and timescales, including harmonic stability and voltage regulation. This is achieved through multi-timescale modeling and control techniques that are not possible with purely mechanical systems. Inverter-based resources allow for distributed coordination of grid services, such as frequency regulation and voltage support, enabling more decentralized grid operation compared to centralized inertia-centric systems. Power electronic systems are essential for grids with a high penetration of renewable energy sources, which lack inherent mechanical inertia. These systems ensure stability while facilitating the transition to low-carbon energy by emulating or replacing traditional generator functions. “I do foresee a time in the not-too-distant future where we’ll be thinking about how do we actually design a system so that we don’t need to be impacted so much by the physical inertia, because it’s preventing us from doing what we want to do,” said Boyd. “I think that time is coming. There will be a lot of challenges to overcome, and there’ll be a lot of learning that needs to be done, but I do think the time is coming.”

The rapid rise of data centers has put many power industry demand forecasters on edge. Some predict the power-hungry nature of the facilities will quickly create problems for utilities and the grid. ICIS, a data analytics provider, calculates that in 2024, demand from data centers in Europe accounted for 96 TWh, or 3.1% of total power demand. “Now, you could say it’s not a lot—3%—it’s just a marginal size, but I’m going to spice it up a bit with two additional layers,” Matteo Mazzoni, director of Energy Analytics at ICIS, said as a guest on The POWER Podcast. “One is: that power demand is very consolidated in just a small subset of countries. So, five countries account of over 60% of that European power demand. And within those five countries, which are the usual suspects in terms of Germany, France, the UK, Ireland, and Netherlands, half of that consumption is located in the FLAP-D market, which sounds like a fancy new coffee, but in reality is just five big cities: Frankfurt, London, Amsterdam, Paris, and Dublin.” Predicting where and how data center demand will grow in the future is challenging, however, especially when looking out more than a few years. “What we’ve tried to do with our research is to divide it into two main time frames,” Mazzoni explained. “The next three to five years, where we see our forecast being relatively accurate because we looked at the development of new data centers, where they are being built, and all the information that are currently available. And, then, what might happen past 2030, which is a little bit more uncertain given how fast technology is developing and all that is happening on the AI [artificial intelligence] front.” Based on its research, ICIS expects European data center power demand to grow 75% by 2030, to 168 TWh. “It’s going to be a lot of the same,” Mazzoni predicted. “So, those big centers—those big cities—are still set to attract most of the additional data center consumption, but we see the emergence of also new interesting markets, like the Nordics and to a certain extent also southern Europe with Iberia [especially Spain] being an interesting market.” Yet, there is still a fair amount of uncertainty around demand projections. Advances in liquid cooling methods will likely reduce data center power usage. That’s because liquid cooling offers more efficient heat dissipation, which translates directly into lower electricity consumption. Additionally, there are opportunities for further improvement in power usage effectiveness (PUE), which is a widely used data center energy efficiency metric. At the global level, the average PUE has decreased from 2.5 in 2007 to a current average of 1.56, according to the ICIS report. However, new facilities consistently achieve a PUE of 1.3 and sometimes much better. Google, which has many state-of-the-art and highly efficient data centers, reported a global average PUE of 1.09 for its facilities over the last year. Said Mazzoni, “An expert in the field told us when we were doing our research, when tech moves out of the equation and you have energy engineers stepping in, you start to see that a lot of efficiency improvements will come, and demand will inevitably fall.” Thus, data center load growth projections should be taken with a grain of salt. “The forecast that we have beyond 2030 will need to be revised,” Mazzoni predicted. “If we look at the history of the past 20 years—all analysts and all forecasts around load growth—they all overshoot what eventually happened. The first time it happened when the internet arrived—there was obviously great expectations—and then EVs, electric vehicles, and then heat pumps. But if we look at, for example, last year—2024—European power demand was up by 1.3%, U.S. power demand was up by 1.8%, and probably weather was the main driver behind that growth.”

District energy systems employ a centralized facility to supply heating, cooling, and sometimes electricity for multiple buildings in an area through a largely underground, mostly unseen network of pipes. When district energy systems are utilized, individual buildings do not need their own boilers, chillers, and cooling towers. This offers a number of benefits to building owners and tenants. Among them are: • Energy Efficiency. Centralized heating/cooling is more efficient than individual building systems, reducing energy use by 30% to 50% in some cases. • Cost Savings. Lower operations and maintenance costs through economies of scale and reduced equipment needs per building. • Reduced Environmental Impacts. Emissions are lessened and renewable energy resources can often be more easily integrated. • Reliability. A more resilient energy supply is often provided, with redundant systems and professional operation. • Space Optimization. Buildings need less mechanical equipment, freeing up valuable space. The concept is far from new. In fact, Birdsill Holly is credited with deploying the U.S.’s first district energy system in Lockport, New York, in 1877, and many other cities incorporated district systems into their infrastructure soon thereafter. While district energy systems are particularly effective in dense urban areas, they’re also widely used at hospitals and at other large campuses around the world. “There’s over 600 operating district energy systems in the U.S., and that’s in cities, also on college and university campuses, healthcare, military bases, airports, pharma, even our sort of newer industries like Meta, Apple, Google, their campuses are utilizing district energy, because, frankly, there’s economies of scale,” Rob Thornton, president and CEO of the International District Energy Association (IDEA), said as a guest on The POWER Podcast. “District energy is actually quite ubiquitous,” said Thornton, noting that systems are common in Canada, throughout Europe, in the Middle East, and many other parts of the world. “But, you know, not that well-known. We’re not visible. Basically, the assets are largely underground, and so we don’t necessarily have the visibility opportunity of like wind turbines or solar panels,” he said. “So, we quietly do our work. But, I would guess that for the listeners of this podcast, if they went to a college or university in North America, I bet, eight out of 10 lived in a dorm that was supplied by a district heating system. So, it’s really a lot more common than people realize,” said Thornton.

Most POWER readers are probably familiar with levelized cost of energy (LCOE) and levelized value of energy (LVOE) as metrics used to help evaluate potential power plant investment options. LCOE measures the average net present cost of electricity generation over a facility’s lifetime. It includes capital costs, fuel costs, operation and maintenance (O&M) costs, financing costs, expected capacity factor, and project lifetime. Meanwhile, LVOE goes beyond LCOE by considering the actual value the power provides to the grid, including time of generation (peak vs. off-peak), location value, grid integration costs and benefits, contributions to system reliability, environmental attributes, and capacity value. Some of the key differences stem from the perspective and market context each provides. LCOE, for example, focuses on pure cost comparison between technologies, while LVOE evaluates actual worth to the power system. Notably, LCOE ignores when and where power is generated; whereas, LVOE accounts for temporal and locational value variations. Concerning system integration, LCOE treats all generation as equally valuable, while LVOE considers grid integration costs and system needs. “Things like levelized cost of energy or capacity factors are probably the wrong measure to use in many of these markets,” Karl Meeusen, director of Markets, Legislative, and Regulatory Policy with Wärtsilä North America, said as a guest on The POWER Podcast. “Instead, I think one of the better metrics to start looking at and using more deeply is what we call the levelized value of energy, and that’s really looking at what the prices at the location where you’re trying to build that resource are going to be.” Wärtsilä is a company headquartered in Finland that provides innovative technologies and lifecycle solutions for the marine and energy markets. Among its main offerings are reciprocating engines that can operate on a variety of fuels for use in electric power generating plants. Wärtsilä has modeled different power systems in almost 200 markets around the world. It says the data consistently shows that a small number of grid-balancing gas engines in a system can provide the balancing and flexibility to enable renewables to flourish—all while maintaining reliable, resilient, and affordable electricity. Meeusen noted that a lot of the models find engines offer greater value than other technologies on the system because of their flexibility, even though they may operate at lower capacity factors. Having the ability to turn on and off allows owners to capture high price intervals, where prices spike because of scarcity or ramp shortages, while avoiding negative prices by turning off as prices start to dip and drop lower. “That levelized value is one of the things that we think is really important going forward,” he said. “I think what a lot of models and planning scenarios miss when they look at something like LCOE—and they’re looking at a single resource added into the system—is how it fits within the system, and what does it do to the value of the rest of their portfolio?” Meeusen explained. “I call this: thinking about the cannibalistic costs. If I look at an LCOE with a capacity factor for a combined cycle resource, and don’t consider how that might impact or increase the curtailment of renewable energy—no cost renewable energy—I don’t really necessarily see the true cost of some of those larger, inflexible generators on the system. And, so, when we think about that, we really want to make sure that what we’re covering and capturing is the true value that a generator has in a portfolio, not just as a standalone resource.”
