The Nuclear Regulatory Commission said that it had rejected a design by Westinghouse for a new reactor because a key component might not withstand events like earthquakes and tornadoes.

The rejection raises the possibility of delays in building 14 planned reactors in the United States, including two twin-reactor projects in Georgia and South Carolina that are leading the pack. Westinghouse, which is owned by Toshiba, promised to conduct tests as quickly as possible to try to satisfy the agency staff that the design was sound.

The new reactor, called the AP1000, is intended to be faster to build and safer to run than previous models. The letters stand for “advanced passive” and the number is the estimated electrical output in megawatts.

Resolving design issues before construction is viewed as a crucial part of the nuclear industryÂ’s plan for a revival without the delays and cost overruns that bedeviled the industry in the 1970s and Â’80s.

The agency staffÂ’s decision, relayed in a letter to Westinghouse, is a glitch in the move toward licensing changes adopted by the commission in the 1990s. The goal was to establish a system through which a library of pre-approved, standardized designs would be available whenever a company set out to build a reactor.

In a conference call with reporters, David Matthews, director of the division of new reactor licensing in the commission’s Office of New Reactors, said staff members were not convinced that a crucial part of the design, a structure called a shield building, would protect the reactor from “external” events like earthquakes, tornadoes and high winds.

The shield consists of 35 inches of concrete sandwiched between two sheets of steel, each of which is half an inch thick. Existing Westinghouse reactors, designed in the 1960s and Â’70s, do not have shield buildings.

In another shift, the new design puts the emergency cooling water on the roof, so that no pumps are needed to deliver it in case of an accident.

Ed Cummins, vice president for regulatory affairs at Westinghouse, said that his company had designed the shield wall to meet a different commission requirement, that the plant be able to withstand the impact of an airliner. But the change had caused the commission staff to question the designÂ’s adequacy to meet natural hazards.

Mr. Cummins said the company was setting up a series of tests, mostly of full-scale models of small parts of the structure, to demonstrate that the shield building could meet the anticipated loads. Utilities in Georgia and South Carolina have begun clearing sites for construction.

Westinghouse did not expect the commission’s concerns to have a “significant impact” on the construction schedule, Mr. Cummins said.

But he added that company officials and the commission staff had not yet determined what kind of work would be needed to demonstrate the structureÂ’s safety.

In a record year for clean energy purchases, Southeast cities stand out

Municipal Renewable Energy Procurement surged as cities contracted 3.7 GW of solar and wind, leveraging green tariffs, community solar, and utility partnerships across the Southeast, led by Houston, RMI, and WRI data.

 

Key Points

The process by which cities contract solar and wind via utilities or green tariffs to meet climate goals.

✅ 3.7 GW procured in 2020, nearly 25% year-over-year growth

✅ Houston runs city ops on 500 MW solar, a record purchase

✅ Southeast cities use green tariffs and community solar

 

Cities around the country bought more renewable energy last year than ever before, reflecting how renewables may soon provide one-fourth of U.S. electricity across the grid, with some of the most remarkable projects in the Southeast, according to new data unveiled Thursday.

Even amid the pandemic, about eight dozen municipalities contracted to buy nearly 3.7 gigawatts of mostly solar and wind energy — enough to power more than 800,000 homes. The figure is almost a quarter higher than the year before.

Half of the cites listed as “most noteworthy” in Thursday’s release —  from research groups Rocky Mountain Institute and World Resources Institute — are in the region that stretches from Texas to Washington, D.C. 

Houston stands out for the sheer enormity of its purchase: In July, it began powering city operations entirely from nearly 500 megawatts of solar power — the largest municipal purchase of renewable energy ever in the United States, as renewable electricity surpassed coal nationwide.

The groups also feature smaller deals in North Carolina and Tennessee, achieved through a utility partnership called a green tariff.

“We wanted to recognize that Nashville and Charlotte were really blazing a new trail,” said Stephen Abbott, principal at the Rocky Mountain Institute.

And the nation’s capital shows how renewable energy can be a source of revenue: It’s leasing out its public transit station rooftops for 10 megawatts of community solar.

All of these strategies will be necessary for scores of U.S. cities to meet their ambitious climate goals, researchers believe. An interactive clean energy targets tracker shows all 95 clean energy procurements from the year in detail.


Tracker 
Even before former President Donald Trump promised to remove the United States from the Paris Climate Accord, a lack of federal action on climate left a void that some cities and counties were beginning to fill, as renewables hit a record 28% in a recent month. In 2015, the first year tracked by researchers at the Rocky Mountain Institute and the World Resources Institute, municipalities contracted to buy more than 1 gigawatt of wind, solar and other forms of clean energy. 

But when Trump officially set in motion the withdrawal from the climate agreement, the ranks of municipalities dedicated to 100% clean energy multiplied. Today there are nearly 200 of them. The growth in activity last year reflects, in part, that surge of new pledges.

“It takes a while to get city staff up to speed and understand the options, and create the roadmap and then start executing,” Abbott said. “There is a bit of a lag, but we’re starting to see the impact.”

Even in Houston — one of the earliest to begin procuring renewable energy — there has been a steep learning curve as market forces change and prices drop, including cheaper solar batteries shaping procurement strategies, said Lara Cottingham, Houston’s chief of staff and chief sustainability officer.

No matter how well resourced and educated their staff, cities have to clear a thicket of structural, political and economic challenges to procure renewable energy. Most don’t own their own sources of power. Nearly all face budget constraints. Few have enough land or government rooftops to meet their goals within city limits.

“Cities face a situation where it’s a square peg in a round hole,” Cottingham said.

The hurdles are especially steep in much of the Southeast, where only publicly regulated utilities can sell electricity to retail customers, even large ones such as major cities. That’s where a green tariff regime comes in: Cities can purchase clean energy from a third party, such as a solar company, using the utility as a go-between.

Early last year, Charlotte became the largest city to use such a program, partnering with Duke Energy and two North Carolina solar developers to build a solar farm 50 miles north in Iredell County. At first, the city will pay a premium for the energy, but in the latter half of the 20-year contract, as gas prices rise, it will save money compared to business as usual.

“Over the course of 20 years, it’s projected we would save about $2 million,” Katie Riddle, sustainability analyst with Charlotte, told the Energy News Network last year.

The growing size of projects, innovative partnerships like green tariff programs, and the improving economics all give Abbott hope that renewable energy investments from cities will only grow — even with the Trump presidency over and the country back in the Paris agreement.

And when cities meet their goals for procuring renewable energy for their own operations, they must then turn to an even bigger task: reducing the carbon footprint of every person in their jurisdiction with broader decarbonization strategies and community engagement.

“The city needs to do its part for sure,” said Houston’s Cottingham. “Then we have this challenge of how do we get everyone else to.”

U.S. offshore wind power about to soar

US Offshore Wind Lease Sales signal soaring renewable energy growth, drawing oil and gas developers, requiring BOEM auctions, seismic surveying, transmission planning, with $70B investment, 8 GW milestones, and substantial job creation in coastal communities.

 

Key Points

BOEM-run auctions granting areas for offshore wind, spurring projects, investment, and jobs in federal waters.

✅ $70B investment needed by 2030 to meet current demand

✅ 8 GW early buildout could create 40,000 US jobs

✅ Requires BOEM auctions, seismic surveying, transmission corridors

 

Recent offshore lease sales demonstrate that not only has offshore wind arrived in the U.S., but it is clearly set to soar, as forecasts point to a $1 trillion global market in the coming decades. The level of participation today, especially from seasoned offshore oil and gas developers, exemplifies that the offshore industry is an advocate for the 'all of the above' energy portfolio.

Offshore wind could generate 160,000 direct, indirect and induced jobs, with 40,000 new U.S. jobs with the first 8 gigawatts of production, while broader forecasts see a quarter-million U.S. wind jobs within four years.

In fact, a recent report from the Special Initiative on Offshore Wind (SIOW), said that offshore wind investment in U.S. waters will require $70 billion by 2030 just based on current demand, and the UK's rapid scale-up offers a relevant benchmark.

Maintaining this tremendous level of interest from offshore wind developers requires a reliable inventory of regularly scheduled offshore wind sales and the ability to develop those resources. Coastal communities and extreme environmental groups opposing seismic surveying and the issuance of incidental harassment authorizations under the Marine Mammal Protection Act may literally take the wind out of these sales. Just as it is for offshore oil and gas development, seismic surveying is vital for offshore wind development, specifically in the siting of wind turbines and transmission corridors.

Unfortunately, a long-term pipeline of wind lease sales does not currently exist. In fact, with the exception of a sale proposed offshore New York offshore wind or potentially California in 2020, there aren't any future lease sales scheduled, leaving nothing upon which developers can plan future investments and prompting questions about when 1 GW will be on the grid nationwide.

NOIA is dedicated to working with the Bureau of Ocean Energy Management and coastal communities, consumers, energy producers and other stakeholders, drawing on U.K. wind lessons where applicable, in working through these challenges to make offshore wind a reality for millions of Americans.

Canada and Manitoba invest in new turbines

Manitoba Clean Electricity Investment will upgrade hydroelectric turbines, expand a 230 kV transmission network, and deliver reliable, affordable low-carbon power, reducing greenhouse gas emissions and strengthening grid reliability across Portage la Prairie and Winnipeg River.

 

Key Points

Joint federal-provincial funding to upgrade hydro turbines and build a 230 kV grid, boosting reliable, low-carbon power.

✅ $314M for new turbines at Pointe du Bois (+52 MW capacity)

✅ $161.6M for 230 kV transmission in Portage la Prairie

✅ Cuts Brandon Generating Station emissions by ~37%

 

The governments of Canada and Manitoba have announced a joint investment of $475.6 million to strengthen Manitoba’s clean electricity grid that can support neighboring provinces with clean power and ensure continued supply of affordable and reliable low-carbon energy.

This federal-provincial investment provides $314 million for eight new hydroelectric turbines at the 75 MW Pointe du Bois Generating Station on the Winnipeg River, as well as $161.6 million to build a new 230 kV transmission network in the Portage la Prairie area, bolstering power sales to SaskPower and regional reliability.

The $314 million joint investment in the Pointe du Bois Renewable Energy Project includes $114.1 million from the Government of Canada and nearly $200 million from the Government of Manitoba. The joint investment will enable Manitoba Hydro to replace eight generating units that are at the end of their lifecycle, amid looming new generation needs for the province. The new, more efficient units will increase the capacity of the Pointe du Bois generating station by 52 MW.

The $161.6 million joint investment in the Portage Area Capacity Enhancement project includes $70.9 million from the Government of Canada and $90.6 million from the Government of Manitoba. The joint investment will support the construction of a new transmission line to enhance reliability for customers across southwest Manitoba and help Manitoba Hydro meet increasing demand, with projections that demand could double over the next two decades. By decreasing Manitoba’s reliance on its last grid-connected fossil-fuel generating station, this investment will reduce greenhouse gas emissions at the Brandon Generating Station by about 37%.

The federal government’s total contribution of $184.9 million is provided through the Green Infrastructure Stream of the Investing in Canada Plan, alongside efforts to improve interprovincial grid integration such as NB Power agreements with Hydro-Quebec that strengthen regional reliability. This federal funding is conditional on meeting Indigenous consultation requirements, as well as environmental assessment obligations. Including today’s announcement, the Green Infrastructure Stream has supported 38 infrastructure projects in Manitoba, for a total federal contribution of more than $766.8 million and a total provincial contribution of over $658.4 million.

“A key part of our economic plan is making Canada a clean electricity superpower. Today’s announcement in Manitoba will deliver clean, reliable, and affordable electricity to people and businesses across the province—and we will continue working to expand our clean electricity grid and create great careers for people from coast to coast to coast,” said Deputy Prime Minister and Finance Minister Chrystia Freeland.

The federal government will continue to invest in making Canada a clean electricity superpower, supporting provincial initiatives like Hydro-Quebec's fossil-free strategy that complement these investments to ensure Canadians from coast to coast to coast have the affordable and reliable clean electricity they need today and for generations to come.

“Manitoba Hydro is extremely pleased to be receiving this federal funding through the Green Infrastructure Stream of the Investing in Canada Infrastructure Program. The investments we are making in both these critical infrastructure projects will help provide Manitobans with energy for life and power our province’s economic growth with clean, reliable, renewable hydroelectricity. These projects build on our legacy of investments in renewable energy over the past 100 years, as we work towards a lower carbon future for all Manitobans,” said Jay Grewal, president and chief executive officer of Manitoba Hydro.

About 97% of Manitoba’s electricity is generated from clean hydro, with most of the remaining 3% coming from wind generation. Manitoba’s abundant clean electricity has resulted in Manitobans paying 9.455 ¢/kWh — the second-lowest electricity rate in Canada, though limits on serving new energy-intensive customers have been flagged recently.

What's at stake if Davis-Besse and other nuclear plants close early?

FirstEnergy Nuclear Plant Closures threaten Ohio and Pennsylvania jobs, tax revenue, and grid stability, as Nuclear Matters and Brattle Group warn of higher carbon emissions and market pressures from PJM and cheap natural gas.

 

Key Points

Planned shutdowns of Davis-Besse, Perry, and Beaver Valley, with regional economic and carbon impacts.

✅ Over 3,000 direct jobs and local tax revenue at risk

✅ Emissions may rise until renewables scale, possibly into 2034

✅ Debate over subsidies, market design, and PJM capacity rules

 

A national nuclear lobby wants to remind people what's at stake for Ohio and Pennsylvania if FirstEnergy Solutions follows through with plans to shut down three nuclear plants over the next three years, including its Davis-Besse nuclear plant east of Toledo.

A report issued Monday by Nuclear Matters largely echoes concerns raised by FES, a subsidiary of FirstEnergy Corp., and other supporters of nuclear power about economic and environmental hardships and brownout risks that will likely result from the planned closures.

Along with Davis-Besse, Perry nuclear plant east of Cleveland and the twin-reactor Beaver Valley nuclear complex west of Pittsburgh are slated to close.

"If these plants close, the livelihoods of thousands of Ohio and Pennsylvania residents will disappear. The over 3,000 highly skilled individuals directly employed by these sites will leave to seek employment at other facilities still operating around the country," Lonnie Stephenson, International Brotherhood of Electrical Workers president, said in a statement distributed by Nuclear Matters. Mr. Stephenson also serves on the Nuclear Matters advocacy council.

This new report and others like it are part of an extensive campaign by nuclear energy advocates to court state and federal legislators one more time for tens of millions of dollars of financial support or at least legislation that better suits the nuclear industry. Critics allege such pleas amount to a request for massive government bailouts, arguing that deregulated electricity markets should not subsidize nuclear.

The latest report was prepared for Nuclear Matters by the Brattle Group, a firm that specializes in analyzing economic, finance, and regulatory issues for corporations, law firms, and governments.

"These announced retirements create a real urgency to learn what would happen if these plants are lost," Dean Murphy, the Brattle report's lead author, said.

More than 3,000 jobs would be lost, as would millions of dollars in tax revenue. It also could take as long as 2034 for the region's climate-altering carbon emissions to be brought back down to existing levels, based on current growth projections for solar- and wind-powered projects, and initiatives such as ending coal by 2032 by some utilities, Mr. Murphy said.

His group's report only takes into account nuclear plant operations, though. Many of those who oppose nuclear power have long pointed out that mining uranium for nuclear plant fuel generates substantial emissions, as does the process of producing steel cladding for fuel bundles and the enrichment-production of that fuel. Still, nuclear has ranked among the better performers in reports that have taken such a broader look at overall emissions.

FES has accused the regional grid operator, PJM Interconnection, of creating market conditions that favor natural gas and, thus, make it almost impossible for nuclear to compete throughout its 13-state region, a debate intensified by proposed electricity pricing changes at the federal level.

PJM has strongly denied those accusations, and has said it anticipates no shortfalls in energy distribution if those nuclear plants close prematurely, even as a recent FERC decision on grid policy drew industry criticism.

FES, citing massive losses, has filed for Chapter 11 bankruptcy. The target dates for closures of the FES properties are May 31, 2020 for Davis-Besse; May 31, 2021 for Perry and Beaver Valley Unit 1, and Oct. 31, 2021 for Beaver Valley Unit 2.

In addition to the three FES sites, the report includes information about the Three Mile Island Unit 1 plant near Harrisburg, Pa., which Chicago-based Exelon Generation Corp. has previously announced will be shut down in 2019. That plant and others are experiencing similar difficulties the FES plants face by competing in a market radically changed by record-low natural gas prices.

Why an energy crisis and $5 gas aren't spurring a green revolution

U.S. Energy Transition Delays stem from grid bottlenecks, permitting red tape, solar tariff uncertainty, supply-chain shocks, and scarce affordable EVs, risking deeper fossil fuel lock-in despite climate targets for renewables, transmission expansion, and decarbonization.

 

Key Points

Delays driven by grid limits, permitting, and supply shocks that slow renewables, transmission, EVs, and decarbonization.

✅ Grid interconnection and transmission backlogs stall renewables

✅ Tariff probes and supply chains disrupt utility-scale solar

✅ Permitting, policy gaps, and EV costs sustain fossil fuel use

 

Big solar projects are facing major delays. Plans to adapt the grid to clean energy are confronting mountains of red tape. Affordable electric vehicles are in short supply.

The United States is struggling to squeeze opportunity out of an energy crisis that should have been a catalyst for cleaner, domestically produced power. After decades of putting the climate on the back burner, the country is finding itself unprepared to seize the moment and at risk of emerging from the crisis even more reliant on fossil fuels.

10 steps you can take to lower your carbon footprint
The problem is not entirely unique to the United States. Across the globe, climate leaders are warning that energy shortages including coal and nuclear disruptions prompted by Russia’s unprovoked invasion of Ukraine and high gas prices driven by inflation threaten to make the energy transition an afterthought — potentially thwarting efforts to keep global temperature rise under 1.5 degrees Celsius.

“The energy crisis exacerbated by the war in Ukraine has seen a perilous doubling down on fossil fuels by the major economies,” U.N. Secretary General António Guterres said at a conference in Vienna on Tuesday, according to prepared remarks. He warned governments and investors that a failure to immediately and more aggressively embrace clean energy could be disastrous for the planet.

U.S. climate envoy John F. Kerry suggested that nations are falling prey to a flawed logic that fossil fuels will help them weather this period of instability, undermining U.S. national security and climate goals, which has seen gas prices climb to a record-high national average of $5 per gallon. “You have this new revisionism suggesting that we have to be pumping oil like crazy, and we have to be moving into long-term [fossil fuel] infrastructure building,” he said at the Time100 Summit in New York this month. “We have to push back.”

In the United States — the world’s second-largest emitter of greenhouse gases after China — the hurdles go beyond the supply-chain crisis and sanctions linked to the war in Ukraine. The country’s lofty goals for all carbon pollution to be gone from the electricity sector by 2035 and for half the cars sold to be electric by 2030 are jeopardized by years of neglect of the electrical grid, regulatory hurdles that have set projects back years, and failures by Congress and policymakers to plan ahead.
The challenges are further compounded by plans to build costly new infrastructure for drilling and exporting natural gas that will make it even harder to transition away from the fossil fuel.

“We are running into structural challenges preventing consumers and businesses from going cleaner, even at this time of high oil and gas prices,” said Paul Bledsoe, a climate adviser in the Clinton administration who now works on strategy at the Progressive Policy Institute, a center-left think tank. “It is a little alarming that even now, Congress is barely talking about clean energy.”

Consumers are eager for more wind and solar. Companies looking to go carbon-neutral are facing growing waitlists for access to green energy, and a Pew Research Center poll in late January found that two-thirds of Americans want the United States to prioritize alternative energy over fossil fuel production.

But lawmakers have balked for more than a decade at making most of the fundamental economic and policy changes such as a clean electricity standard that experts widely agree are crucial to an orderly and accelerated energy transition. The United States does not have a tax on carbon, nor a national cap-and-trade program that would reorient markets toward lowering emissions. The unraveling in Congress of President Biden’s $1.75 trillion Build Back Better plan has added to the head winds that green-energy developers face, even as climate law results remain mixed.

“There is literally nothing pushing this forward in the U.S. beyond the tax code and some state laws,” said Heather Zichal, a former White House climate adviser who is now the chief executive of the American Clean Power Association.

The effects of the U.S. government’s halting approach are being felt by solar-panel installers, who saw the number of projects in the most recent quarter fall to the lowest level since the pandemic began. There was 24 percent less solar installed in the first quarter of 2022 than in the same quarter of 2021.

The holdup largely stems from a Commerce Department investigation into alleged tariff-dodging by Chinese manufacturers. Faced with the potential for steep retroactive penalties, hundreds of industrial-scale solar projects were frozen in early April. Weak federal policies to encourage investment in solar manufacturing left American companies ill-equipped to fill the void.

“We shut down multiple projects and had to lay off dozens of people,” said George Hershman, chief executive of SOLV Energy, which specializes in large solar installations. SOLV, like dozens of other solar companies, is now scrambling to reassemble those projects after the administration announced a pause of the tariffs.

Meanwhile, adding clean electricity to the aging power grid has become an increasingly complicated undertaking, given the failure to plan for adequate transmission lines and long delays connecting viable wind and solar projects to the electricity network.

How ‘Virtual Power Plants’ Will Change The Future Of Electricity

Virtual Power Plants orchestrate distributed energy resources like rooftop solar, home batteries, and EVs to deliver grid services, demand response, peak shaving, and resilience, lowering costs while enhancing reliability across wholesale markets and local networks.

 

Key Points

Virtual Power Plants aggregate solar and batteries to provide grid services, cut peak costs, and boost reliability.

✅ Aggregates DERs via cloud to bid into wholesale markets

✅ Reduces peak demand, defers costly grid upgrades

✅ Enhances resilience vs outages, cyber risks, and wildfires

 

If “virtual” meetings can allow companies to gather without anyone being in the office, then remotely distributed solar panels and batteries can harness energy and act as “virtual power plants.” It is simply the orchestration of millions of dispersed assets within a smarter electricity infrastructure to manage the supply of electricity — power that can be redirected back to the grid and distributed to homes and businesses. 

The ultimate goal is to revamp the energy landscape, making it cleaner and more reliable. By using onsite generation such as rooftop solar and smart solar inverters in combination with battery storage, those services can reduce the network’s overall cost by deferring expensive infrastructure upgrades and by reducing the need to purchase cost-prohibitive peak power. 

“We expect virtual power plants, including aggregated home solar and batteries, to become more common and more impactful for energy consumers throughout the country in the coming years,” says Michael Sachdev, chief product officer for Sunrun Inc., a rooftop solar company, in an interview. “The growth of home solar and batteries will be most apparent in places where households have an immediate need for backup power, as they do in California, where grid reliability pressures have led utilities to turn off the electricity to reduce wildfire risk.”

Home battery adoption, such as Tesla Powerwall systems, is becoming commonplace in Hawaii and in New England, he adds, because those distributed assets are improving the efficiency of the electrical network. It is a trend that is reshaping the country’s energy generation and delivery system by relying more on clean onsite generation and less on fossil fuels.

Sunrun has recently formed a business partnership with AutoGrid, which will manage Sunrun’s fleet of rechargeable batteries. It is a cloud-based system that allows Sunrun to work with utilities to dispatch its “storage fleet” to optimize the economic results. AutoGrid compiles the data and makes AI-driven forecasts that enable it to pinpoint potential trouble spots. 

But a distributed energy system, or a virtual power plant, would have 200,000 subsystems. Or, 200,000 5 kilowatt batteries would be the equivalent of one power plant that has a capacity of 1,000 megawatts. 

“A virtual power plant acts as a generator,” says Amit Narayan, chief executive officer of AutoGrid, in an interview. “It is one of the top five innovations of the decade. If you look at Sunrun, 60% of every solar system it sells in the Bay Area is getting attached to a battery. The value proposition comes when you can aggregate these batteries and market them as a generation unit. The pool of individual assets may improve over time. But when you add these up, it is better than a large-scale plant. It is like going from mainframe computers to laptops.”

The AutoGrid executive goes on to say that centralized systems are less reliable than distributed resources. While one battery could falter, 200,000 of them that operate from remote locations will prove to be more durable — able to withstand cyber attacks and wildfires. Sunrun’s Sachdev adds that the ability to store energy in batteries, as seen in California’s expanding grid-scale battery use supporting reliability, and to move it to the grid on demand creates value not just for homes and businesses but also for the network as a whole.

The good news is that the trend worldwide is to make it easier for smaller distributed assets, including energy storage for microgrids that support local resilience, to get the same regulatory treatment as power plants. System operators have been obligated to call up those power supplies that are the most cost-effective and that can be easily dispatched. But now regulators are giving virtual power plants comprised of solar and batteries the same treatment. 

In the United States, for example, the Federal Energy Regulatory Commission issued an order in 2018 that allows storage resources to participate in wholesale markets — where electricity is bought directly from generators before selling that power to homes and businesses. Under the ruling, virtual power plants are paid the same as traditional power suppliers. A federal appeals court this month upheld the commission’s order, saying that it had the right to ensure “technological advances in energy storage are fully realized in the marketplace.” 

“In the past, we have used back-up generators,” notes AutoGrid’s Narayan. “As we move toward more automation, we are opening up the market to small assets such as battery storage and electric vehicles. As we deploy more of these assets, there will be increasing opportunities for virtual power plants.” 

Virtual power plants have the potential to change the energy horizon by harnessing locally-produced solar power and redistributing that to where it is most needed — all facilitated by cloud-based software that has a full panoramic view. At the same time, those smaller distributed assets can add more reliability and give consumers greater peace-of-mind — a dynamic that does, indeed, beef-up America’s generation and delivery network.
