At a forum hosted in New York by the NYSE Euronext at the New York Stock Exchange, The Green Grid announced new tools and reports to assist business leaders and data center managers globally improve efficiency in their operations.

Representatives from The Green Grid, United States Environmental Protection Agency and United States Department of Energy, along with executives from a variety of industries, shared their challenges with data center energy management and offered practical steps for improvement.

The Green Grid presented the results of a recently completed assessment of a mid-tier data center operated by the EPA, along with recommendations for next steps that EPA can follow to improve efficiency.

"We applaud EPA's leadership in opening up their operations to this level of examination, and we encourage other organizations to work with us to develop standards and explore ways they can improve their own operations," said John Tuccillo, Chairman of the Board of The Green Grid. "If the EPA can deploy techniques that improve efficiency by 20 percent, they can save $15,000 per year in this one data center. IDC estimates that there are 75,000 similar-sized data centers across the United States, and if all of them could achieve that same level of savings, more than $1.1 billion in annual energy costs could be avoided in data centers across the country."

"We want to thank The Green Grid for their commitment to helping improve energy efficiency in data centers across the globe," said Linda Travers, Acting Chief Information Officer and Acting Assistant Administrator, Office of Environmental Information, EPA. "This is an excellent first step in the government's path to operating as efficiently as possible. As October is Energy Awareness Month, this marks an appropriate occasion for others to follow our lead."

The Green Grid continues to assist the Department of Energy in testing and validating the DC Pro tool, an online software tool provided by the U.S. Department of Energy to help industries worldwide identify how energy is being consumed by their data center(s) and identify the best opportunities for savings.

The Green Grid and the U.S. Department of Energy Save Energy Now program are working together to enhance the Department of Energy's DC Pro software tool suite by:

• ensuring common energy metrics between The Green Grid tools, DC Pro and the ENERGY STAR portfolio manager tool;

• developing an IT energy assessment module; and

• creating a complementary Certified Energy Practitioner program where data center energy professionals would perform energy assessments using DC Pro.

The Green Grid also announced new free online tools and maps designed to help data center and facilities managers in Japan and 33 European countries easily determine how much outside air — also known as free cooling — is available for individual data centers.

These new tools provide data center managers in Japan and Europe with real-world data to help lower energy consumption and related costs, potentially extending the life and improving the energy efficiency of data center facilities.

Using country and city names, data center managers in Europe or Japan can input their specific variables — such as local energy costs, IT load, and facility load — to determine the specific potential energy savings for individual facilities. In addition to free cooling from outside air, the tool provides information about savings that could be obtained using water-side economizers. For example:

• A 1 megawatt (1000kW) data center in Paris, France, with power at 13.2 cents per kW hour, could save EUR330,000 per year using free cooling, or EUR180,000 per year using a water-side economizer.

• A 1 megawatt (1000kw) data center in Tokyo, Japan, with power at JPY 24 per kW hour, could save JPY 43,020,000 per year using free cooling, or JPY 27,500,000 per year using a water side economizer.

Tools are now available for the U.S., Japan, and the following European countries: Armenia, Austria, Azerbaijan, Belarus, Belgium, Bulgaria, Czech Republic, Denmark, Estonia, Finland, France, Georgia, Germany, Greece, Hungary, Italy, Ireland, Latvia, Lithuania, Macedonia, Netherlands, Norway, Poland, Portugal, Romania, Russian Federation, Slovakia, Slovenia, Spain, Sweden, Switzerland, Ukraine, and United Kingdom.

The Green Grid also introduced a new free online tool for data center managers to record their Power Usage Effectiveness (PUE) scores that will establish global consistency in reporting the split between energy flowing to IT equipment and facility operations.

"The Green Grid's PUE metric is now widely adopted as the standard for measuring data center efficiency, and we've taken necessary steps to refine it so that it becomes even more impactful," said The Green Grid's Tuccillo. "We expect that the user-driven database will be an invaluable tool for data center managers to determine the relative energy efficiency of their operations by comparing to others across industries, or even inside their own company."

Brenmiller Energy and New York Power Authority Showcase Thermal Storage Success

bGen Thermal Energy Storage stores high-temperature heat in crushed rocks, enabling on-demand steam, hot water, or hot air; integrates renewables, shifts load with off-peak electricity, and decarbonizes campus heating at SUNY Purchase with NYPA.

 

Key Points

A rock-based TES system storing heat to deliver steam, hot water, or hot air using renewables or off-peak power.

✅ Uses crushed rocks to store high-temperature heat

✅ Cuts about 550 metric tons CO2 annually at SUNY Purchase

✅ Integrates renewables and off-peak electricity with NYPA

 

Brenmiller Energy Ltd. (NASDAQ: BNRG), in collaboration with the New York Power Authority (NYPA), a utility pursuing grid software modernization to improve reliability, has successfully deployed its first bGen™ thermal energy storage (TES) system in the United States at the State University of New York (SUNY) Purchase College. This milestone project, valued at $2.5 million, underscores the growing role of TES in advancing sustainable energy solutions.

Innovative TES Technology

The bGen™ system utilizes crushed rocks to store high-temperature heat, which can be harnessed to generate steam, hot air, or hot water on demand. This approach allows for the efficient use of excess renewable energy or off-peak electricity, and parallels microreactor storage advances that broaden thermal options, providing a reliable and cost-effective means of meeting heating needs. At SUNY Purchase College, the bGen™ system is designed to supply nearly 100% of the heating requirements for the Physical Education Building.

Environmental Impact

The implementation of the bGen™ system is expected to eliminate approximately 550 metric tons of greenhouse gas emissions annually. This reduction aligns with New York State's ambitious climate goals, including a 40% reduction in greenhouse gas emissions by 2030, even as transmission constraints can limit cross-border imports. The project also demonstrates the potential of TES to support the state's transition to a cleaner and more resilient energy system.

Collaborative Effort

The successful deployment of the bGen™ system at SUNY Purchase College is the result of a collaborative effort between Brenmiller Energy and NYPA. The project was partially funded by a grant from the Israel-U.S. Binational Industrial Research and Development (BIRD) Foundation. This partnership highlights the importance of international cooperation in advancing innovative energy technologies, as seen in OPG-TVA nuclear collaboration efforts across North America.

Future Prospects

The successful installation and operation of the bGen™ system at SUNY Purchase College serve as a model for broader adoption of TES technology in institutional settings, as OPG's SMR commitment signals parallel low-carbon investment across the region. Brenmiller Energy and NYPA plan to share the project's findings through a webinar hosted by the Renewable Thermal Collaborative on May 19, 2025. This initiative aims to promote the scalability and replicability of TES solutions across New York State and beyond.

As the demand for sustainable energy solutions continues to grow, the successful deployment of the bGen™ system at SUNY Purchase College marks a significant step forward in the integration of TES technology into the U.S. energy landscape, while projects like Pickering B refurbishment underscore parallel clean power investments. The project not only demonstrates the feasibility of TES but also sets a precedent for future initiatives aimed at reducing carbon emissions and enhancing energy efficiency.

Brenmiller Energy's commitment to innovation and sustainability positions the company as a key player in the evolving energy sector. With continued support from partners like NYPA and the BIRD Foundation, and as jurisdictions advance first SMR deployments in North America, Brenmiller Energy is poised to expand the reach of its TES solutions, contributing to a more sustainable and resilient energy future.

Tracking Progress on 100% Clean Energy Targets

100% Clean Energy Targets drive renewable electricity, decarbonization, and cost savings through state policies, CCAs, RECs, and mandates, with timelines and interim goals that boost jobs, resilience, and public health across cities, counties, and utilities.

 

Key Points

Policies for cities and states to reach 100% clean power by set dates, using mandates, RECs, and interim goals.

✅ Define eligible clean vs renewable resources

✅ Mandate vs goal framework with enforcement

✅ Timelines with interim targets and escape clauses

 

“An enormous amount of authority still rests with the states for determining your energy future. So we can build these policies that will become a postcard from the future for the rest of the country,” said David Hochschild, chair of the California Energy Commission, speaking last week at a UCLA summit on state and local progress toward 100 percent clean energy.

According to a new report from the UCLA Luskin Center for Innovation, 13 states, districts and territories, as well as more than 200 cities and counties, with standout clean energy purchases by Southeast cities helping drive momentum, have committed to a 100 percent clean electricity target — and dozens of cities have already hit it.

This means that one of every three Americans, or roughly 111 million U.S. residents representing 34 percent of the population, live in a community that has committed to or has already achieved 100 percent clean electricity, including communities like Frisco, Colorado that have set ambitious targets.

“We’re going to look back on this moment as the moment when local action and state commitments began to push the entire nation toward this goal,” said J.R. DeShazo, director of the UCLA Luskin Center for Innovation.

Not all 100 percent targets are alike, however. The report notes that these targets vary based on 1) what resources are eligible, 2) how binding the 100 percent target is, and 3) how and when the target will be achieved.

These distinctions will carry a lot of weight as the policy discussion shifts from setting goals to actually meeting targets. They also have implications for communities in terms of health benefits, cost savings and employment opportunities.

 

100% targets come in different forms

One key attribute is whether a target is based on "renewable" or "clean" energy resources. Some 100 percent targets, like Hawaii’s and Rhode Island’s 2030 plan, are focused exclusively on renewable energy, or sources that cannot be depleted, such as wind, solar and geothermal. But most jurisdictions use the broader term “clean energy,” which can also include resources like large hydroelectric generation and nuclear power.

States also vary in their treatment of renewable energy certificates, used to track and assign ownership to renewable energy generation and use. Unbundled RECs allow for the environmental attributes of the renewable energy resource to be purchased separately from the physical electricity delivery.

The binding nature of these targets is also noteworthy. Seven states, as well as Puerto Rico and the District of Columbia, have passed 100 percent clean energy transition laws. Of the jurisdictions that have passed 100 percent legislation, all but one specifies that the target is a “mandate,” according to the report. Nevada is the only state to call the target a “goal.”

Governors in four other states have signed executive orders with 100 percent clean energy goals.

Target timelines also vary. Washington, D.C. has set the most ambitious target date, with a mandate to achieve 100 percent renewable electricity by 2032. Other states and cities have set deadline years between 2040 and 2050. All "100 percent" state laws, and some city and county policies, also include interim targets to keep clean energy deployment on track.

In addition, some locations have included some form of escape clause. For instance, Salt Lake City, which last month passed a resolution establishing a goal of powering the county with 100 percent clean electricity by 2030, included “exit strategies” in its policy in order to encourage stakeholder buy-in, said Mayor Jackie Biskupski, speaking last week at the UCLA summit.

“We don’t think they’ll get used, but they’re there,” she said.

Other locales, meanwhile, have decided to go well beyond 100 percent clean electricity. The State of California and 44 cities have set even more challenging targets to also transition their entire transportation, heating and cooling sectors to 100 percent clean energy sources, and proposals like requiring solar panels on new buildings underscore how policy can accelerate progress across sectors.

Businesses are simultaneously electing to adopt more clean and renewable energy. Six utilities across the United States have set their own 100 percent clean or carbon-free electricity targets. UCLA researchers did not include populations served by these utilities in their analysis of locations with state and city 100 percent clean commitments.

 

“We cannot wait”

All state and local policies that require a certain share of electricity to come from renewable energy resources have contributed to more efficient project development and financing mechanisms, which have supported continued technology cost declines and contributed to a near doubling of renewable energy generation since 2008.

Many communities are switching to clean energy in order to save money, now that the cost calculation is increasingly in favor of renewables over fossil fuels, as more jurisdictions get on the road to 100% renewables worldwide. Additional benefits include local job creation, cleaner air and electricity system resilience due to greater reliance on local energy resources.

Another major motivator is climate change. The electricity sector is responsible for 28 percent of U.S. greenhouse gas emissions, second only to transportation. Decarbonizing the grid also helps to clean up the transportation sector as more vehicles move to electricity as their fuel source.

“The now-constant threat of wildfires, droughts, severe storms and habitat loss driven by climate change signals a crisis we can no longer ignore,” said Carla Peterman, senior vice president of regulatory affairs at investor-owned utility Southern California Edison. “We cannot wait and we should not wait when there are viable solutions to pursue now.”

Prior to joining SCE on October 1, Peterman served as a member of the California Public Utilities Commission, which implements and administers renewable portfolio standard (RPS) compliance rules for California’s retail sellers of electricity. California’s target requires 60 percent of the state’s electricity to come from renewable energy resources by 2030, and all the state's electricity to come from carbon-free resources by 2045.  

 

How CCAs are driving renewable energy deployment

One way California communities are working to meet the state’s ambitious targets is through community-choice aggregation, especially after California's near-100% renewable milestone underscored what's possible, via which cities and counties can take control of their energy procurement decisions to suit their preferences. Investor-owned utilities no longer purchase energy for these jurisdictions, but they continue to operate the transmission and distribution grid for all electricity users.                           

A second paper released by the Luskin Center for Innovation in recent days examines how community-choice aggregators are affecting levels of renewable energy deployment in California and contributing to the state’s 100 percent target.

The paper finds that 19 CCAs have launched in California since 2010, growing to include more than 160 towns, cities and counties. Of those communities, 64 have a 100 percent renewable or clean energy policy as their default energy program.

Because of these policies, the UCLA paper finds that “CCAs have had both direct and indirect effects that have led to increases in the clean energy sold in excess of the state’s RPS.”

From 2011 to 2018, CCAs directly procured 24 terawatt-hours of RPS-eligible electricity, 11 TWh of which have been voluntary or in excess of RPS compliance, according to the paper.

The formation of CCAs has also had an indirect effect on investor-owned utilities. As customers have left investor-owned utilities to join CCAs, the utilities have been left holding contracts for more renewable energy than they need to comply with California’s clean energy targets, amid rising solar and wind curtailments that complicate procurement decisions. UCLA researchers estimate that this indirect effect of CCA formation has left IOUs holding 13 terawatt-hours in excess of RPS requirements.

The paper concludes that CCAs have helped to accelerate California’s ability to meet state renewable energy targets over the past decade. However, the future contributions of CCAs to the RPS are more uncertain as communities make new power-purchasing decisions and utilities seek to reduce their excess renewable energy contracts.

“CCAs offer a way for communities to put their desire for clean energy into action. They're growing fast in California, one of only eight states where this kind of mechanism is allowed," said UCLA's Kelly Trumbull, an author of the report. "State and federal policies could be reformed to better enable communities to meet local demand for renewable energy.”

BC Ferries celebrates addition of hybrid ships

BC Ferries Island Class hybrid ferries deliver quiet, battery-electric travel with shore power readiness, lower emissions, and larger capacity on northern routes, protecting marine wildlife while replacing older vessels on Powell River and Texada services.

 

Key Points

Hybrid-electric ferries using batteries and diesel for quiet, low-emission service, ready for shore power upgrades.

✅ Operate 20% electric at launch; future full-electric via shore power

✅ 300 passengers, 47 vehicles; replacing older, smaller vessels

✅ Quieter transits help protect West Coast whales and marine habitat

 

In a champagne celebration, BC Ferries welcomed two new, hybrid-electric ships into its fleet Wednesday. The ships arrived in Victoria last month, and are expected to be in service on northern routes by the summer.

The Island Aurora and Island Discovery have the ability to run on either diesel or electricity.

"The pressure on whales on the West Coast is very intense right now," said BC Ferries CEO Mark Collins. "Quiet operation is very important. These ships will be gliding out of the harbor quietly and electrically with no engines running, that will be really great for marine space."

BC Ferries says the ships will be running on electricity 20 per cent of the time when they enter service, but the company hopes they can run on electricity full-time in the future. That would require the installation of shoreline power, which the company hopes to have in place in the next five to 10 years. Each ship costs around $40-million, a price tag that the federal government partially subsidized through CIB support as part of the electrification push.

When the two ships begin running on the Powell River to Texada, and Port McNeill, Alert Bay, and Sointula routes, two older vessels will be retired.

On Kootenay Lake, an electric-ready ferry is slated to begin operations in 2023, reflecting the province's wider shift.

"They are replacing a 47-car ferry, but on some routes they will be replacing a 25-car ferry, so those routes will see a considerable increase in service," said Collins.

Although the ships will not be servicing Colwood, the municipality's mayor is hoping that one day, they will.

"We can look at an electric ferry when we look at a West Shore ferry that would move Colwood residents to Victoria," said Mayor Rob Martin, noting that across the province electric school buses are hitting the road as well. "Here is a great example of what BC Ferries can do for us."

BC Ferries says it will be adding four more hybrid ships to its fleet by 2022, and is working on adding hybrid ships that could run from Victoria to Tsawwassen, similar to Washington State Ferries' hybrid upgrade underway in the region. 

B.C’s first hybrid-electric ferries arrived in Victoria on Saturday morning ushering in a new era of travel for BC Ferries passengers, as electric seaplane flights are also on the horizon for the region.

“It’s a really exciting day for us,” said Tessa Humphries, spokesperson for BC Ferries.

It took the ferries 60 days to arrive at the Breakwater District at Ogden Point. They came all the way from Constanta, Romania.

“These are battery-equipped ships that are designed for fully electric operation; they are outfitted with hybrid technology that bridges the gap until the EV charging infrastructure and funding is available in British Columbia,” said Humphries.

The two new "Island Class" vessels arrived at about 9 a.m. to a handful of people eagerly wanting to witness history.

Sometime in the next few days, the transport ship that brought the new ferries to B.C. will go out into the harbor and partially submerge to allow them to be offloaded, Humphries said.

The transfer process could happen in four to five days from now. After the final preparations are finished at the Breakwater District, the ships will be re-commissioned in Point Hope Maritime and then BC Ferries will officially take ownership.

“We know a lot of people are interested in this so we will put out advisory once we have more information as to a viewing area to see the whole process,” said Humphries.

Both Island Class ferries can carry 300 passengers and 47 vehicles. They won’t be sailing until later this year, but Humphries tells CTV News they will be named by the end of February.

France hopes to keep Brussels sweet with new electricity pricing scheme

France Electricity Pricing Mechanism aligns with EU rules, leveraging nuclear energy and EDF profits, avoiding Contracts for Difference, redistributing windfalls to industry and households, targeting €70/MWh amid electricity market reform and Brussels oversight.

 

Key Points

A framework to keep power near €70/MWh by reclaiming EDF windfalls and redistributing them under EU market rules.

✅ Targets average price near €70/MWh from 2026

✅ Skims EDF profits above €78-80 and €110/MWh thresholds

✅ Aligns with EU rules; avoids nuclear CfDs and state aid clashes

 

France has unveiled a new electricity pricing mechanism, hoping to defuse months of tension over energy subsidies with Brussels and its neighbors.

The strain has included a Franco-German fight over EU electricity reform with Germany accusing France of wanting to subsidize its industry via artificially low energy prices, while Paris maintained it should have the right to make the most of its relatively cheap nuclear energy. That fight has now been settled.

On Tuesday, the French government presented a new mechanism — complex, and still-to-be-detailed — to bring the average price of electricity closer to €70 per megawatt hour (MWh) as of 2026, amid Europe's electricity market revamp efforts.

"The agreement has been defined to comply with European rules and avoid difficulties with the European Commission," said France's Economy and Finance Minister Bruno Le Maire, noting that France had ruled out other "simpler" options that would have caused tension with Brussels.

For example, France has not yet envisaged the use of state-backed investment schemes called Contracts for Difference (CfD), which were the main source of discord in talks with Germany on the electricity market reform and the EU push for more fixed-price contracts in generation. The compromise agreed by EU ministers last month gives the Commission the power to monitor CfDs in the nuclear sector.

"France wanted to limit as much as possible the European Commission's nuisance power," said Phuc-Vinh Nguyen, an energy expert at the Jacques Delors Institute think tank in Paris.

The announcement came weeks after French President Emmanuel Macron promised that France would "take back control" of its electricity prices to allow its industry to make the most of the country's relatively cheap nuclear energy.

Germany, by contrast, has moved to support energy-intensive industries with an industrial electricity subsidy, underscoring the policy divergence.

“The price of electricity has always been a major competitive advantage for the French nation, and it must remain so,” Le Maire said.

Under the new mechanism, part of a broader deal on electricity prices between the state and EDF, the government will seize EDF profits above certain thresholds and redistribute them directly to industry and households to bring prices closer to the desired level. Specifically, the government will redistribute 50 percent of EDF’s additional profits if prices rise above €78-€80 per MWh, and 90 percent of extra profits if prices rise above €110 per MWh.

The move also marks a new step in the government's power grab at EDF, after the company was fully nationalized earlier this year.

For years, France has been discussing an EDF reform with the Commission in order to address concerns by Brussels regarding disguised state aid to the company. In particular, the Commission wanted assurances that any state aid given to nuclear would be kept separate from those parts of the business subject to competition, such as renewable energy development.

An economy ministry official close to Le Maire argued that the new pricing mechanism would settle matters with Brussels on that front. A Commission spokesperson said Brussels was in contact with France on the file, but declined further comment.

The mechanism will replace the existing EU-mandated energy pricing mechanism, dubbed ARENH, which was set to expire at the end of 2025, and which has forced EDF to sell some of its electricity to competitors at a fixed low price since 2010, and comes amid contested electricity market reforms at EU level.

The new system could benefit EDF because it won't be bound to sell energy at a lower price, but instead will be allowed to auction off its energy to competitors. On the other hand, the redistribution system would deprive the company of some profits when electricity prices are higher. No wonder, then, that negotiations between the government and EDF have been "difficult," as Le Maire put it.

Opinion: UK Natural Gas, Rising Prices and Electricity

European Energy Market Crisis drives record natural gas and electricity prices across the EU, as LNG supply constraints, Russian pipeline dependence, marginal pricing, and renewables integration expose volatility in liberalised power markets.

 

Key Points

A 2021 surge in European gas and electricity prices from supply strains, demand rebounds, and marginal pricing exposure.

✅ Record TTF gas and day-ahead power prices across Europe

✅ LNG constraints and Russian pipeline dependence tightened supply

✅ Debate over marginal pricing vs regulated models intensifies

 

By Ronan Bolton

The year 2021 was a turbulent one for energy markets across Europe, as Europe's energy nightmare deepened across the region. Skyrocketing natural gas prices have created a sense of crisis and will lead to cost-of-living problems for many households, as wholesale costs feed through into retail prices for gas and electricity over the coming months.

This has created immediate challenges for governments, but it should also encourage us to rethink the fundamental design of our energy markets as we seek to transition to net zero, with many viewing it as a wake-up call to ditch fossil fuels across the bloc.

This energy crisis was driven by a combination of factors: the relaxation of Covid-19 lockdowns across Europe created a surge in demand, while cold weather early in the year diminished storage levels and contributed to increasing demand from Asian economies. A number of technical issues and supply-side constraints also combined to limit imports of liquefied natural gas (LNG) into the continent.

Europe’s reliance on pipeline imports from Russia has once again been called into question, as Gazprom has refused to ride to the rescue, only fulfilling its pre-existing contracts. The combination of these, and other, factors resulted in record prices – the European benchmark price (the Dutch TTF Gas Futures Contract) reached almost €180/MWh on 21 December, with average day-ahead electricity prices exceeding €300/MWh across much of the continent in the following days.

Countries which rely heavily on natural gas as a source of electricity generation have been particularly exposed, with governments quickly put under pressure to intervene in the market.

In Spain the government and large energy companies have clashed over a proposed windfall tax on power producers. In Ireland, where wind and gas meet much of the country’s surging electricity demand, the government is proposing a €100 rebate for all domestic energy consumers in early 2022; while the UK government is currently negotiating a sector-wide bailout of the energy supply sector and considering ending the gas-electricity price link to curb bills.

This follows the collapse of a number of suppliers who had based their business models on attracting customers with low prices by buying cheap on the spot market. The rising wholesale prices, combined with the retail price cap previously introduced by the Theresa May government, led to their collapse.

While individual governments have little control over prices in an increasingly globalised and interconnected natural gas market, they can exert influence over electricity prices as these markets remain largely national and strongly influenced by domestic policy and regulation. Arising from this, the intersection of gas and power markets has become a key site of contestation and comment about the role of government in mitigating the impacts on consumers of rising fuel bills, even as several EU states oppose major reforms amid the price spike.

Given that renewables are constituting an ever-greater share of production capacity, many are now questioning why gas prices play such a determining role in electricity markets.

As I outline in my forthcoming book, Making Energy Markets, a particular feature of the ‘European model’ of liberalised electricity trade since the 1990s has been a reliance on spot markets to improve the efficiency of electricity systems. The idea was that high marginal prices – often set by expensive-to-run gas peaking plants – would signal when capacity limits are reached, providing clear incentives to consumers to reduce or delay demand at these peak periods.

This, in theory, would lead to an overall more efficient system, and in the long run, if average prices exceeded the costs of entering the market, new investments would be made, thus pushing the more expensive and inefficient plants off the system.

The free-market model became established during a more stable era when domestically-sourced coal, along with gas purchased on long-term contracts from European sources (the North Sea and the Netherlands), constituted a much greater proportion of electricity generation.

While prices fluctuated, they were within a somewhat predictable range, and provided a stable benchmark for the long-term contracts underpinning investment decisions. This is no longer the case as energy markets become increasingly volatile and disrupted during the energy transition.

The idea that free price formation in a competitive market, with governments standing back, would benefit electricity consumers and lead to more efficient systems was rooted in sound economic theory, and is the basis on which other major commodity markets, such as metals and agricultural crops, have been organised for decades.

The free-market model applied to electricity had clear limitations, however, as the majority of domestic consumers have not been exposed directly to real-time price signals. While this is changing with the roll-out of smart meters in many countries, the extent to which the average consumer will be willing or able to reduce demand in a predicable way during peak periods remains uncertain.

Also, experience shows that governments often come under pressure to intervene in markets if prices rise sharply during periods of scarcity, thus undermining a basic tenet of the market model, with EU gas price cap strategies floated as one option.

Given that gas continues to play a crucial role in balancing supply and demand for electricity, the options available to governments are limited, illustrating why rolling back electricity prices is harder than it appears for policymakers. One approach would be would be to keep faith with the liberalised market model, with limited interventions to help consumers in the short term, while ultimately relying on innovations in demand side technologies and alternatives to gas as a means of balancing systems with high shares of variable renewables.

An alternative scenario may see a return to old style national pricing policies, involving a move away from marginal pricing and spot markets, even as the EU prepares to revamp its electricity market in response. In the past, in particular during the post-WWII decades, and until markets were liberalised in the 1990s, governments have taken such an approach, centrally determining prices based on the costs of delivering long term system plans. The operation of gas plants and fuel procurement would become a much more regulated activity under such a model.

Many argue that this ‘traditional model’ better suits a world in which governments have committed to long-term decarbonisation targets, and zero marginal cost sources, such as wind and solar, play a more dominant role in markets and begin to push down prices.

A crucial question for energy policy makers is how to exploit this deflationary effect of renewables and pass-on cost savings to consumers, whilst ensuring that the lights stay on.

Despite the promise of storage technologies such as grid-scale batteries and hydrogen produced from electrolysis, aside from highly polluting coal, no alternative to internationally sourced natural gas as a means of balancing electricity systems and ensuring our energy security is immediately available.

This fact, above all else, will constrain the ambitions of governments to fundamentally transform energy markets.

Solar PV and wind power in the US continue to grow amid favourable government plans

US Renewable Power Outlook 2030 projects surging capacity, solar PV and wind growth, grid modernization, and favorable tax credits, detailing market trends, CAGR, transmission expansion, and policy drivers shaping clean energy generation and consumption.

 

Key Points

A forecast of US power capacity, generation, and consumption, highlighting solar, wind, tax credits, and grid modernization.

✅ Targets 48.4% renewable capacity share by 2030

✅ Strong growth in solar PV and onshore wind installations

✅ Investment and tax credits drive grid and transmission upgrades

 

GlobalData’s latest report, ‘United States Power Market Outlook to 2030, Update 2021 – Market Trends, Regulations, and Competitive Landscape’ discusses the power market structure of the United States and provides historical and forecast numbers for capacity, generation and consumption up to 2030. Detailed analysis of the country’s power market regulatory structure, competitive landscape and a list of major power plants are provided. The report also gives a snapshot of the power sector in the country on broad parameters of macroeconomics, supply security, generation infrastructure, transmission and distribution infrastructure, about a quarter of U.S. electricity from renewables in recent years, electricity import and export scenario, degree of competition, regulatory scenario, and future potential. An analysis of the deals in the country’s power sector is also included in the report.

Renewable power held a 19% share of the US’s total power capacity in 2020, and in that year renewables became the second-most prevalent source in the U.S. electricity mix by generation; this share is expected to increase significantly to 48.4% by 2030. Favourable policies introduced by the US Government will continue to drive the country’s renewable sector, particularly solar photovoltaics (PV) and wind power, with wind now the most-used renewable source in the U.S. generation mix. Installed renewable capacity* increased from 16.5GW in 2000 to 239.2GW in 2020, growing at a compound annual growth rate (CAGR) of 14.3%. By 2030, the cumulative renewable capacity is expected to rise to 884.6GW, growing at a CAGR of 14% from 2020 to 2030. Despite increase in prices of renewable equipment, such as solar modules, in 2021, the US renewable sector will show strong growth during the 2021 to 2030 period as this increase in equipment prices are short term due to supply chain disruptions caused by the Covid-19 pandemic.

The expansion of renewable power capacity during the 2000 to 2020 period has been possible due to the introduction of federal schemes, such as Production Tax Credits, Investment Tax Credits and Manufacturing Tax Credits. These have massively aided renewable installations by bringing down the cost of renewable power generation and making it at par with power generated from conventional sources. Over the last few years, the cost of solar PV and wind power installations has declined sharply, and by 2023 wind, solar, and batteries made up most of the utility-scale pipeline across the US, highlighting investor confidence. Since 2010, the cost of utility-scale solar PV projects decreased by around 82% while onshore wind installations decreased by around 39%. This has supported the rapid expansion of the renewable market. However, the price of solar equipment has risen due to an increase in raw material prices and supply shortages. This may slightly delay the financing of some solar projects that are already in the pipeline.

The US will continue to add significant renewable capacity additions during the forecast period as industry outlooks point to record solar and storage installations over the coming years, to meet its target of reaching 80% clean energy by 2030. In November 2021, President Biden signed a $1tr Infrastructure Bill, within which $73bn is designated to renewables. This includes not just renewable capacity building, but also strengthening the country’s power grid and laying new high voltage transmission lines, both of which will be key to driving solar and wind power capacity additions as wind power surges in the U.S. electricity mix nationwide.

The US was one of the worst hit countries in the world due to the Covid-19 pandemic in 2020. With respect to the power sector, the electricity consumption in the country declined by 2.5% in 2020 as compared to 2019, even as renewable electricity surpassed coal in 2022 in the generation mix, highlighting continued structural change. Power plants that were under construction faced delays due to unavailability of components due to supply chain disruptions and unavailability of labour due to travel restrictions.

According to the US Energy Information Administration, 61 power projects, having a total capacity of 2.4GWm which were under construction during March and April 2020 were delayed because of the Covid-19 pandemic. Among renewable power technologies, solar PV and wind power projects were the most badly affected due to the pandemic.

In March and April 2020, 53 solar PV projects, having a total capacity of 1.3GW, and wind power projects, having a total capacity of 1.2GW, were delayed due to the Covid-19 pandemic. Moreover, several states suspended renewable energy auctions due to the pandemic.

For instance, New York State Energy Research and Development Authority (NYSERDA) had issued a new offshore wind solicitation for 1GW and up to 2.5GW in April 2020, but this was suspended due to the Covid-19 pandemic. In July 2020, the authority relaunched the tender for 2.5GW of offshore wind capacity, with a submission deadline in October 2020.

To ease the financial burden on consumers during the pandemic, more than 1,000 utilities in the country announced disconnection moratoria and implemented flexible payment plans. Duke Energy, American Electric Power, Dominion Power and Southern California Edison were among the major utilities that voluntarily suspended disconnections.
