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.

Germany nuclear phase-out underscores a high-stakes energy transition, trading reactors for renewables, LNG imports, and grid resilience to secure supply, cut emissions, and navigate climate policy, public opinion shifts, and post-Ukraine supply shocks.

Key Points

Germany's nuclear phase-out retires reactors, shifting to renewables, LNG, and grid upgrades for low-carbon power.

✅ Last three reactors: Neckarwestheim, Isar 2, and Emsland closed

✅ Supply secured via LNG imports, renewables, and grid flexibility

✅ Policy accelerated post-Fukushima; debate renewed after Ukraine war

The German government is phasing out nuclear power despite the energy crisis. The country is pulling the plug on its last three reactors, betting it will succeed in its green transition without nuclear power.

On the banks of the Neckar River, not far from Stuttgart in south Germany, the white steam escaping from the nuclear power plant in Baden-Württemberg will soon be a memory.

The same applies further east for the Bavarian Isar 2 complex and the Emsland complex, at the other end of the country, not far from the Dutch border.

While many Western countries depend on nuclear power, Europe's largest economy is turning the page, even if a possible resurgence of nuclear energy is debated until the end.

Germany is implementing the decision to phase out nuclear power taken in 2002 and accelerated by Angela Merkel in 2011, after the Fukushima disaster.

Fukushima showed that "even in a high-tech country like Japan, the risks associated with nuclear energy cannot be controlled 100 per cent", the former chancellor justified at the time.

The announcement convinced public opinion in a country where the powerful anti-nuclear movement was initially fuelled by fears of a Cold War conflict, and then by accidents such as Chernobyl.

The invasion of Ukraine on 24 February 2022 brought everything into question. Deprived of Russian gas, the flow of which was essentially interrupted by Moscow, Germany found itself exposed to the worst possible scenarios, from the risk of its factories being shut down to the risk of being without heating in the middle of winter.

With just a few months to go before the initial deadline for closing the last three reactors on 31 December, the tide of public opinion began to turn, and talk of a U-turn on the nuclear phaseout grew louder. 

"With high energy prices and the burning issue of climate change, there were of course calls to extend the plants," says Jochen Winkler, mayor of Neckarwestheim, where the plant of the same name is in its final days.

Olaf Scholz's government, which the Green Party - the most hostile to nuclear power - is part of, finally decided to extend the operation of the reactors to secure the supply until 15 April.

"There might have been a new discussion if the winter had been more difficult if there had been power cuts and gas shortages nationwide. But we have had a winter without too many problems," thanks to the massive import of liquefied natural gas, notes Mr Winkler.

Ontario-U.S. Energy Tariff Dispute highlights cross-border trade tensions, retaliatory tariffs, export surcharges, and White House negotiations as Doug Ford meets U.S. officials to de-escalate pressure over steel, aluminum, and energy supplies.

Key Points

A trade standoff over energy exports and tariffs, sparked by Ontario's surcharge and U.S. duties on steel and aluminum.

✅ 25% Ontario energy surcharge paused before White House talks

✅ U.S. steel and aluminum tariffs reduced from 50% to 25%

✅ Potential energy supply cutoff remains leverage in negotiations

Ontario Premier Doug Ford's recent high-stakes diplomatic trip to Washington, D.C., underscores the delicate trade tensions between Canada and the United States, particularly concerning energy exports and Canada's electricity exports across the border. Ford's potential use of tariffs or even halting U.S. energy supplies, amid Ontario's energy independence considerations, remains a powerful leverage tool, one that could either de-escalate or intensify the ongoing trade conflict between the two neighboring nations.

The meeting in Washington follows a turbulent series of events that began with Ontario's imposition of a 25% surcharge on energy exports to the U.S. This move came in retaliation to what Ontario perceived as unfair treatment in trade agreements, a step that aligned with Canadian support for tariffs at the time. In response, U.S. President Donald Trump's administration threatened its own set of tariffs, specifically targeting Canadian steel and aluminum, which further escalated tensions. U.S. officials labeled Ford's threat to cut off U.S. electricity exports and energy supplies as "egregious and insulting," warning of significant economic retaliation.

However, shortly after these heated exchanges, Trump’s commerce secretary, Howard Lutnick, extended an invitation to Ford for a direct meeting at the White House. Ford described this gesture as an "olive branch," signaling a potential de-escalation of the dispute. In the lead-up to this diplomatic encounter, Ford agreed to pause the energy surcharge, allowing the meeting to proceed, amid concerns tariffs could spike NY energy prices, without further escalating the crisis. Trump's administration responded by lowering its proposed 50% tariff on Canadian steel and aluminum to a more manageable 25%.

The outcome of the meeting, which is set to address these critical issues, could have lasting implications for trade relations between Canada and the U.S. If Ford and Lutnick can reach an agreement, the potential for tariff imposition on energy exports, though experts advise against cutting Quebec's energy exports due to broader risks, could be resolved. However, if the talks fail, it is likely that both countries could face further retaliatory measures, compounding the economic strain on both sides.

As Canada and the U.S. continue to navigate these complex issues, where support for Canadian energy projects has risen, the outcome of Ford's meeting with Lutnick will be closely watched, as it could either defuse the tensions or set the stage for a prolonged trade battle.

Ontario IESO COVID-19 Control Room Measures detail how essential operators safeguard the electricity grid with split shifts, backup control centres, real-time balancing, deep cleaning, social distancing, and shelter-in-place readiness to maintain reliable power.

Key Points

Measures that protect essential grid operators with split shifts, backup sites, and hygiene to keep power reliable.

✅ Split teams across primary and backup control centres

✅ 12-hour shifts with remote handoffs and deep cleaning

✅ Real-time grid modeling to balance demand and supply

A group of personnel key to keeping Ontario's electricity system functioning may end up locked down in their control centres due to the COVID-19 crisis, according to the head of the province's power operator.

But that has so far proven unnecessary with a change-up in routine, Independent Electricity System Operator CEO Peter Gregg said.

While about 90 per cent of staff were sent to work from home on March 13, another 48 control-room operators deemed essential are still going into work, Gregg said in an interview.

"We identified a smaller cohort of critical operations room staff that need to go in to operate the system out of our control centres," Gregg said. "My biggest concern is to maintain their health, their safety as we rely on them to do this critical work."

Some of the operators manage power demand and supply in real time as Ontario electricity demand shifts, by calling for more or less generation and keeping an eye on the distribution grid, which also allows power to flow to and from Ontario's neighbours. Others do scenario planning and modelling to prepare for changes.

The essential operators have been split into eight teams of six each working 12-hour shifts. The day crew works out of a control centre near Toronto and the night shift out of a backup centre in the city's west end, Gregg said.

"That means that we're not having physical hand-off between control room operators on shift change -- we can do it remotely -- and it also allows us to do deep cleansing," Gregg said. "We're fortunate that the way the room is set up allows us to practice good social distancing."

Should it become necessary, he said, bed, food and other on-site arrangements have been made to allow the operators to stay at their workplaces as a similar agency in New York has done.

"If we do need to shelter these critical employees in place, we've got the ability to do so."

IESO is responsible for ensuring a balance between supply and demand for electricity across the province. Because power cannot be stored, the IESO ensures generators produce enough power to meet peak demand while making sure they don't produce too much.

"You're seeing, obviously, commercial demand drop, some industrial demand drop," Gregg said. "But you're also seeing a shift in the demand curve as well, where normally you have people heading off to work and so residential demand would go down. But obviously with them staying home, you're seeing an increase in residential electricity use across the province."

Some utilities have indicated no cuts to peak rates for self-isolating customers, with Hydro One peak pricing remaining in place for now.

IESO also runs and settles the wholesale electricity markets. Market prices are set based on accepted offers to supply electricity, while programs supporting stable electricity pricing for industrial and commercial users can affect costs against forecast demand.

With the pandemic forcing many businesses to close and people to stay home, and provincial electricity relief for families and small businesses in place, typical power needs fallen about seven per cent at a time of year that would normally see demand soften anyway. It remains to be seen whether, and how much, power needs shift further amid stringent isolation measures and the ongoing economic impact of the outbreak.

Gregg said the operator is constantly modeling different possibilities.

"What we do normally is prepare for all of these sort of emergency scenarios, as reflected in the U.S. grid response coverage, and test and drill for these," he said. "What we're experiencing over the last few weeks is that those drills come in handy because they help us prepare for when the real-time situation actually happens."

Offshore Wind Cost Competitiveness is rising as larger turbines boost megawatt output, cut LCOE, and trim maintenance and installation time, enabling projects in New England to rival natural gas pricing while scaling reliably.

Key Points

It describes how larger offshore turbines lower LCOE and O&M, making U.S. projects price competitive with natural gas.

✅ Larger turbines boost MW output and reduce LCOE.

✅ Lower O&M and faster installation cut lifecycle costs.

✅ Competes with gas in New England bids, per BNEF.

Massive offshore wind turbines keep getting bigger, as projects like the biggest UK offshore wind farm come online, and that’s helping make the power cheaper — to the point where developers say new projects in U.S. waters can compete with natural gas.

The price “is going to be a real eye-opener,” said Bryan Martin, chairman of Deepwater Wind LLC, which won an auction in May to build a 400-megawatt wind farm southeast of Rhode Island.

Deepwater built the only U.S. offshore wind farm, a 30-megawatt project that was completed south of Block Island in 2016. The company’s bid was selected by Rhode Island the same day that Massachusetts picked Vineyard Wind to build an 800-megawatt wind farm in the same area, while international investors such as Japanese utilities in UK projects signal growing confidence.

Bigger turbines that make more electricity have cut the cost per megawatt by about half, a trend aided by higher-than-expected wind potential in many markets, said Tom Harries, a wind analyst at Bloomberg New Energy Finance. That also reduces maintenance expenses and installation time. All of this is helping offshore wind vie with conventional power plants.

“You could not build a thermal gas plant in New England for the price of the wind bids in Massachusetts and Rhode Island,” Martin said Friday at the U.S. Offshore Wind Conference in Boston. “It’s very cost-effective for consumers.”

The Massachusetts project could be about $100 to $120 a megawatt hour, according to a February estimate from Harries, though recent UK price spikes during low wind highlight volatility. The actual prices there and in Rhode Island weren’t disclosed.

For comparison, a new U.S. combine-cycle gas turbine ranges from $40 to $60 a megawatt-hour, and a new coal plant is $67 to $113, according to BNEF data.

A new power plant in land-constrained New England would probably be higher than that, and during winter peaks the region has seen record oil-fired generation in New England that underscores reliability concerns. More importantly, gas plants get a significant portion of their revenue from being able to guarantee that power is always available, something wind farms can’t do, said William Nelson, a New York-based analyst with BNEF. Looking only at the price at which offshore turbines can deliver electricity is a “narrow mindset,” he said.

Bruce Power Capacity Uprate boosts nuclear output through generator stator upgrades, turbine and transformer enhancements, and cooling pump improvements at Bruce A and B, unlocking megawatts and efficiency gains from legacy heavy water design capacity.

Key Points

Upgrades that raise Bruce Power capacity via stator, turbine, transformer, and cooling enhancements.

✅ Generator stator replacement increases electrical conversion efficiency

✅ Turbine and transformer upgrades enable higher MW output

✅ Cooling pump enhancements optimize plant thermal performance

Bruce Power’s Unit 3 nuclear reactor will squeeze out an extra 22 megawatts of electricity, thanks to upgrades during its recent planned outage for refurbishment.

Similar gains are anticipated at its three sister reactors at Bruce A generating station, which presents the opportunity for the biggest efficiency gains and broader economic benefits for Ontario, due to a design difference over Bruce B’s four reactors, Bruce Power spokesman John Peevers said.

Bruce A reactor efficiency gains stem mainly from the fact Bruce A’s non-nuclear side, including turbines and the generator, was sized at 88 per cent of the nuclear capacity, Peevers said, while early Bruce C exploration work advances.

This allowed 12 per cent of the energy, in the form of steam, to be used for heavy water production, which was discontinued at the plant years ago. Heavy water, or deuterium, is used to moderate the reactors.

That design difference left a potential excess capacity that Bruce Power is making use of through various non-nuclear enhancements. But the nuclear operator, which also made major PPE donations during the pandemic, will be looking at enhancements at Bruce B as well, Peevers said.

Bruce Power’s efficiency gain came from “technology advancements,” including a “generator-stator improvement project that was integral to the uprate,” and contributed to an operating record at the site, a Bruce Power news release said July 11.

Peevers said the stationary coils and the associated iron cores inside the generator are referred to as the stator. The stator acts as a conductor for the main generator current, while the turbine provides the mechanical torque on the shaft of the generator.

“Some of the other things we’re working on are transformer replacement and cooling pump enhancements, backed by recent manufacturing contracts, which also help efficiency and contribute to greater megawatt output,” Peevers said.

The added efficiency improvements raised the nuclear operator’s peak generating capacity to 6,430 MW, as projects like Pickering life extensions continue across Ontario.
