TorontoÂ’s iconic wind turbine on the edge of Lake Ontario has been brought to a grinding halt by a combination of a bearing failure and, ironically, high winds.

The lazily spinning, three-bladed turbine at the Exhibition grounds has been frozen since mid-March. ItÂ’s the latest hiccup for the project, which was launched in 2002 when 427 investors raised $800,000 to buy 8,000 shares in the 750-kilowatt generator.

Windshare, the co-operative which runs the turbine, hopes to get it up and running as soon as the weather co-operates, said president Dianne Saxe.

“The cranes are there, the bearing is there and they’re working on it,” she said adding getting a bearing itself was a challenge. “Every time we’d find a bearing for sale it would be sold. Because of the demand for wind power, demand for these bearings is also high and they sell them as soon as they make them.”

Indeed, the blades were off before the windstorm hit.

Compounding the issue was the bankruptcy of the Dutch windmill manufacturer, Lagerwey, which rendered the maintenance contract and warranty useless, said Ms. Saxe.

While WindshareÂ’s original investors split dividend payments of $32,000 from the sale of power in 2005, profits since then have been ploughed back into the turbine for maintenance, Ms. Saxe said, adding the bearing replacement will cost $200,000.

“We had no idea how to run it, and, so in 2006, 2007, 2008 there was a lot of downtime, though it was working,” she said. “Then a couple of volunteers took it on themselves to learn how to run it. Thanks to them in 2009 and 2010 it ran at 95 per cent, generating about 1000 megawatts enough to power 200 homes for a year.”

Still making money from the turbine wasnÂ’t the goal, said Ms. Saxe, an environmental lawyer who drives a hybrid. It is also not part of the Ontario governmentÂ’s Feed In Tariff program, which subsidizes almost all other wind and solar projects in the province.

“It was built to demonstrate the technology and raise the profile of wind energy,” she said.

Windshare hoped to build a second turbine at Ashbridges Bay and raised $300,000 from investors for that, but discussions with the Toronto Port Authority broke down. In the meantime, it is developing a project in the Bruce Peninsula pending transmission line logistics and is working on a similar concept, Solarshare, to install solar panels on rooftops in Toronto.

Electric Cooperatives, The Lone Shining Utility Star Of The Texas 2021 Winter Storm

Texas Electric Cooperatives outperformed during Winter Storm Uri, with higher customer satisfaction, equitable rolling blackouts, and stronger grid reliability compared to deregulated markets, according to ERCOT-area survey data of regulated utilities and commercial providers.

 

Key Points

Member-owned utilities in Texas delivering power, noted for reliability and fair outages during Winter Storm Uri.

✅ Member-owned, regulated utilities serving local communities

✅ Rated higher for blackout management and communication

✅ Operate outside deregulated markets; align incentives with users

 

Winter Storm Uri began to hit parts of Texas on February 13, 2021 and its onslaught left close to 4.5 million Texas homes and businesses without power, and many faced power and water disruptions at its peak. By some accounts, the preliminary number of deaths attributed to the storm is nearly 200, and the economic toll for the Lone Star State is estimated to be as high as $295 billion. 

The more than two-thirds of Texans who lost power during this devastating storm were notably more negative than positive in their evaluation of the performance of their local electric utility, mirrored by a rise in electricity complaints statewide, with one exception. That exception are the members of the more than 60 electric cooperatives operating within the Texas Interconnection electrical grid, which, in sharp contrast to the customers of the commercial utilities that provide power to the majority of Texans, gave their local utility a positive evaluation related to its performance during the storm.

In order to study Winter Storm Uri’s impact on Texas, the Hobby School of Public Affairs at the University of Houston conducted an online survey during the first half of March of residents 18 and older who live in the 213 counties (91.5% of the state population) served by the Texas power grid, which is managed by the Electric Reliability Council of Texas (ERCOT). 

Three-quarters of the survey population (75%) live in areas with a deregulated utility market, where a specified transmission and delivery utility by region is responsible for delivering the electricity (purchased from one of a myriad of private companies by the consumer) to homes and businesses. The four main utility providers are Oncor, CenterPoint CNP -2.2%, American Electric Power (AEP) North, and American Electric Power (AEP) Central. 

The other 25% of the survey population live in areas with regulated markets, where a single company is responsible for both delivering the electricity to homes and businesses and serves as the only source from which electricity is purchased. Municipal-owned and operated utilities (e.g., Austin Energy, Bryan Texas Utilities, Burnet Electric Department, Denton Municipal Electric, New Braunfels Utilities, San Antonio’s CPS Energy CMS -2.1%) serve 73% of the regulated market. Electric cooperatives (e.g., Bluebonnet Electric Cooperative, Central Texas Electric Cooperative, Guadalupe Valley Cooperative, Lamb County Electric Cooperative, Pedernales Electricity Cooperative, Wood County Electric Cooperative) serve one-fifth of this market (21%), with private companies accounting for 6% of the regulated market.

The overall distribution of the survey population by electric utility providers is: Oncor (38%), CenterPoint (21%), municipal-owned utilities (18%), AEP Central & AEP North combined (12%), electric cooperatives (6%), other providers in the deregulated market (4%) and other providers in the regulated market (1%). 

There were no noteworthy differences among the 31% of Texans who did not lose power during the winter storm in regard to their evaluations of their local electricity provider or their belief that the power cuts in their locale were carried out in an equitable manner.  

However, among the 69% of Texans who lost power, those served by electric cooperatives in the regulated market and those served by private electric utilities in the deregulated market differed notably regarding their evaluation of the performance of their local electric utility, both in regard to their management of the rolling blackouts, amid debates over market reforms to avoid blackouts, and to their overall performance during the winter storm. Those Texans who lost power and are served by electric cooperatives in a regulated market had a significantly more positive evaluation of the performance of their local electric utility than did those Texans who lost power and are served by a private company in a deregulated electricity market. 

For example, only 24% of Texans served by electric cooperatives had a negative evaluation of their local electric utility’s overall performance during the winter storm, compared to 55%, 56% and 61% of those served by AEP, Oncor and CenterPoint respectively. A slightly smaller proportion of Texans served by electric cooperatives (22%) had a negative evaluation of their local electric utility’s performance managing the rolling blackouts during the winter storm, compared to 58%, 61% and 71% of Texans served by Oncor, AEP and CenterPoint, respectively.

Texans served by electric cooperatives in regulated markets were more likely to agree that the power cuts in their local area were carried out in an equitable manner compared to Texans served by commercial electricity utilities in deregulated markets. More than half (52%) of those served by an electric cooperative agreed that power cuts during the winter storm in their area were carried out in an equitable manner, compared to only 26%, 23% and 23% of those served by Oncor, AEP and CenterPoint respectively

The survey data did not allow us to provide a conclusive explanation as to why the performance during the winter storm by electric cooperatives (and to a much lesser extent municipal utilities) in the regulated markets was viewed more favorably by their customers than was the performance of the private companies in the deregulated markets viewed by their customers. Yet here are three, far from exhaustive, possible explanations.

First, electric cooperatives might have performed better (based on objective empirical metrics) during the winter storm, perhaps because they are more committed to their customers, who are effectively their bosses. .  

Second, members of electric cooperatives may believe their electric utility prioritizes their interests more than do customers of commercial electric utilities and therefore, even if equal empirical performance were the case, are more likely to rate their electric utility in a positive manner than are customers of commercial utilities.  

Third, regulated electric utilities where a single entity is responsible for the commercialization, transmission and distribution of electricity might be better able to respond to the type of challenges presented by the February 2021 winter storm than are deregulated electric utilities where one entity is responsible for commercialization and another is responsible for transmission and distribution, aligning with calls to improve electricity reliability across Texas.

Other explanations for these findings may exist, which in addition to the three posited above, await future empirical verification via new and more comprehensive studies designed specifically to study electric cooperatives, large commercial utilities, and the incentives that these entities face under the regulatory system governing production, commercialization and distribution of electricity, including rulings that some plants are exempt from providing electricity in emergencies under state law. 

Still, opinion about electricity providers during Winter Storm Uri is clear: Texans served by regulated electricity markets, especially by electric cooperatives, were much more satisfied with their providers’ performance than were those in deregulated markets. Throughout its history, Texas has staunchly supported the free market. Could Winter Storm Uri change this propensity, or will attempts to regulate electricity lessen as the memories of the storm’s havoc fades? With a hotter summer predicted to be on the horizon in 2021 and growing awareness of severe heat blackout risks, we may soon get an answer.

Integrating AI Data Centers into Canada's Electricity Grids

Canada AI Data Center Grid Integration aligns AI demand with renewable energy, energy storage, and grid reliability. It emphasizes transmission upgrades, liquid cooling efficiency, and policy incentives to balance economic growth with sustainable power.

 

Key Points

Linking AI data centers to Canada's grid with renewables, storage, and efficiency to ensure reliable, sustainable power.

✅ Diversify supply with wind, solar, hydro, and firm low-carbon resources

✅ Deploy grid-scale batteries to balance peaks and enhance reliability

✅ Upgrade transmission, distribution, and adopt liquid cooling efficiency

 

Artificial intelligence (AI) is revolutionizing various sectors, driving demand for data centers that support AI applications. In Canada, this surge in data center development presents both economic opportunities and challenges for the electricity grid, where utilities using AI to adapt to evolving demand dynamics. Integrating AI-focused data centers into Canada's electricity infrastructure requires strategic planning to balance economic growth with sustainable energy practices.​

Economic and Technological Incentives

Canada has been at the forefront of AI research for over three decades, establishing itself as a global leader in the field. The federal government has invested significantly in AI initiatives, with over $2 billion allocated in 2024 to maintain Canada's competitive edge and to align with a net-zero grid by 2050 target nationwide. Provincial governments are also actively courting data center investments, recognizing the economic and technological benefits these facilities bring. Data centers not only create jobs and stimulate local economies but also enhance technological infrastructure, supporting advancements in AI and related fields.​

Challenges to the Electricity Grid

However, the energy demands of AI data centers pose significant challenges to Canada's electricity grid, mirroring the power challenge for utilities seen in the U.S., as demand rises. The North American Electric Reliability Corporation (NERC) has raised concerns about the growing electricity consumption driven by AI, noting that the current power generation capacity may struggle to meet this increasing demand, while grids are increasingly exposed to harsh weather conditions that threaten reliability as well. This situation could lead to reliability issues, including potential blackouts during peak demand periods, jeopardizing both economic activities and the progress of AI initiatives.​

Strategic Integration Approaches

To effectively integrate AI data centers into Canada's electricity grids, a multifaceted approach is essential:

  1. Diversifying Energy Sources: Relying solely on traditional energy sources may not suffice to meet the heightened demands of AI data centers. Incorporating renewable energy sources, such as wind, solar, and hydroelectric power, can provide sustainable alternatives. For instance, Alberta has emerged as a proactive player in supporting AI-enabled data centers, with the TransAlta data centre agreement expected to advance this momentum, leveraging its renewable energy potential to attract such investments.
     

  2. Implementing Energy Storage Solutions: Integrating large-scale battery storage systems can help manage the intermittent nature of renewable energy. These systems store excess energy generated during low-demand periods, releasing it during peak times to stabilize the grid. In some communities, AI-driven grid upgrades complement storage deployments to optimize operations, which supports data center needs and community reliability.
     

  3. Enhancing Grid Infrastructure: Upgrading transmission and distribution networks is crucial to handle the increased load from AI data centers. Strategic investments in grid infrastructure can prevent bottlenecks and ensure efficient energy delivery, including exploration of macrogrids in Canada to improve regional transfers, supporting both existing and new data center operations.​
     

  4. Adopting Energy-Efficient Data Center Designs: Designing data centers with energy efficiency in mind can significantly reduce their power consumption. Innovations such as liquid cooling systems are being explored to manage the heat generated by high-density AI workloads, offering more efficient alternatives to traditional air cooling methods.

  5. Establishing Collaborative Policies: Collaboration among government entities, utility providers, and data center operators is vital to align energy policies with technological advancements. Developing regulatory frameworks that incentivize sustainable practices can guide the growth of AI data centers in harmony with grid capabilities.​
     

Integrating AI data centers into Canada's electricity grids presents both significant opportunities and challenges. By adopting a comprehensive strategy that includes diversifying energy sources, implementing advanced energy storage, enhancing grid infrastructure, promoting energy-efficient designs, and fostering collaborative policies, Canada can harness the benefits of AI while ensuring a reliable and sustainable energy future. This balanced approach will position Canada as a leader in both AI innovation and sustainable energy practices.

'That can keep you up at night': Lessons for Canada from Europe's power crisis

Canada Net-Zero Grid Lessons highlight Europe's energy transition risks: Germany's power prices, wind and solar variability, nuclear phaseout, grid reliability, storage, market design, policy reforms, and distributed energy resources for resilient decarbonization.

 

Key Points

Lessons stress an all-of-the-above mix, robust market design, storage, and nuclear to ensure reliability, affordability.

✅ Diversify: nuclear, hydro, wind, solar, storage for reliability.

✅ Reform markets and grid planning for integration and flexibility.

✅ Build fast: streamline permitting, invest in transmission and DERs.

 

Europe is currently suffering the consequences of an uncoordinated rush to carbon-free electricity that experts warn could hit Canada as well unless urgent action is taken.

Power prices in Germany, for example, hit a record 91 euros ($135 CAD) per megawatt-hour earlier this month. That is more than triple what electricity costs in Ontario, where greening the grid could require massive investment, even during periods of peak demand.

Experts blame the price spikes in large part on a chaotic transition to a specific set of renewable electricity sources - wind and solar - at the expense of other carbon-free supplies such as nuclear power. Germany, Europe’s largest economy, plans to close its last remaining nuclear power plant next year despite warnings that renewables are not being added to the German grid quickly enough to replace that lost supply.

As Canada prepares to transition its own electricity grid to 100 per cent net-zero supplies by 2035, with provinces like Ontario planning new wind and solar procurement, experts say the European power crisis offers lessons this country must heed in order to avoid a similar fate.

'A CAUTIONARY TALE'
“Some countries have rushed their transition without thinking about what people need and when they need it,” said Chris Bentley, managing director of Ryerson University’s Legal Innovation Zone who also served as Ontario’s Minister of Energy from 2011 to 2013, in an interview. “Germany has experienced a little bit of this issue recently when the wind wasn’t blowing.”

Wind power usually provides between 20 and 30 per cent of Germany’s electricity needs, but the below-average breeze across much of continental Europe in recent months has pushed that figure down.

“There is a cautionary tale from the experience in Europe,” said Francis Bradley, chief executive officer of the Canadian Electricity Association, in an interview. “There was also a cautionary tale from what took place this past winter in Texas,” he added, referring to widespread power failures in Texas spawned by a lack of backup power supplies during an unusually cold winter that led to many deaths.

The first lesson Canada must learn from those cautionary tales, Bradley said, “is the need to pursue an all-of-the-above approach.”

“It is absolutely essential that every opportunity and every potential technology for low-carbon or no-carbon electricity needs to be pursued and needs to be pursued to the fullest,” he said.

The more important lesson for Canada, according to Binnu Jeyakumar, is about the need for a more holistic, nuanced approach to our own net-zero transition.

“It is very easy to have runaway narratives that just pinpoint the blame on one or two issues, but the lesson here isn’t really about the reliability of renewables as there are failures that occur across all sources of electricity supply,” said Jeyakumar, director of clean energy for the Pembina Institute, in an interview. 

“The takeaway for us is that we need to get better at learning how to integrate an increasingly diverse electricity grid,” she said. “It is not necessarily the technologies themselves, it is about how we do grid planning, how are our markets structured and are we adapting them to the trends that are evolving in the electricity and energy sectors.”
 

'ABSOLUTELY ENORMOUS' CHALLENGE IS 'ALMOST MIND-BENDING'
Canada already gets the vast majority of its electricity from emission-free sources. Hydro provides roughly 60 per cent of our power, nuclear contributes another 15 per cent and renewables such as wind and solar contribute roughly seven per cent more, according to federal government data.

Tempting as it might be to view the remaining 18 per cent of Canadian electricity that is supplied by oil, natural gas and coal as a small enough proportion that it should be relatively easy to replace, with some analyses warning that scrapping coal abruptly can be costly for consumers, the reality is much more difficult.

“It is the law of diminishing returns or the 80-20 rule where the first 80 per cent is easy but the last 20 per cent is hard,” Bradley explained. “We already have an electricity sector that is 80 per cent GHG-free, so getting rid of that last 20 per cent is the really difficult part because the low-hanging fruit has already been picked.”

Key to successfully decarbonizing Canada’s power grid will be the recognition that electricity demand is constantly growing, a point reinforced by a recent power challenges report that underscores the scale. That means Canada needs to build out enough emission-free power sources to replace existing fossil fuel-based supplies while also ensuring adequate supplies for future demand.


“It is one thing to say that by 2035 we are going to have a decarbonized electricity system, but the challenge really is the amount of additional electricity that we are going to need between now and 2035,” said John Gorman, chief executive officer of the Canadian Nuclear Association, which has argued that nuclear is key to climate goals in Canada, and former CEO of the Canadian Solar Industries Association, in an interview. “It is absolutely enormous, I mean, it is almost mind-bending.”

Canada will need to triple the amount of electricity produced nationwide by 2050, according to a report from SNC-Lavalin published earlier this year, and provinces such as Ontario face a shortfall over the next few years, Gorman said. Gorman said that will require adding between five and seven gigawatts of new installed capacity to Canada’s electricity grid every year from 2021 through 2050 or more than twice the amount of new power supply Canada brings online annually right now.

For perspective, consider Ontario’s Bruce Power nuclear facility. It took 27 years to bring that plant to its current 6.4 gigawatt (GW) capacity, but meeting Canada’s decarbonization goals will require adding roughly the equivalent capacity of Bruce Power every year for the next three decades.

“The task of creating enough electricity in the coming years is truly enormous and governments have not really wrapped their heads around that yet,” Gorman said. “For those of us in the energy sector, it is the type of thing that can keep you up at night.”

GOVERNMENT POLICY 'HELD HOSTAGE' BY 'DINOSAURS'
The Pembina Institute’s Jeyakumar agreed “the last mile is often the most difficult” and will require “a concerted effort both at the federal level and the provincial level.”

Governments will “need to be able to support innovation and solutions such as non-wires alternatives,” she said. “Instead of building a massive new transmission line or beefing up an old one, you could put a storage facility at the end of an existing line. Distributed energy resources provide those kinds of non-wires alternatives and they are already cost-effective and competitive with oil and gas.”

For Glen Murray, who served as Ontario’s minister of infrastructure and transportation from early 2013 to mid-2014 before assuming the environment and climate change portfolio until his resignation in mid-2017, that is a key lesson governments have yet to learn.

“We are moving away from a centralized distribution model to distributed systems where individual buildings and homes and communities will supply their own electricity needs,” said Murray, who currently works for an urban planning software company in Winnipeg, in an interview. “Yet both the federal and provincial governments are assuming that we are going to continue to have large, centralized generation of power, but that is simply not going to be the case.”

“Government policy is not focused on driving that because they are held hostage by their own hydro utilities and the big gas companies,” Murray said. “They are controlling the agenda even though they are the dinosaurs.”

Referencing the SNC-Lavalin report, Gorman noted as many as 45 small, modular nuclear reactors as well as 20 conventional nuclear power plants will be required in the coming decades, with jurisdictions like Ontario exploring new large-scale nuclear as part of that mix: “And that is in the context of also maximizing all the other emission-free electricity sources we have available as well from wind to solar to hydro and marine renewables,” Gorman said, echoing the “all-of-the-above” mindset of the Canadian Electricity Association.

There are, however, “fundamental rules of the market and the regulatory system that make it an uneven playing field for these new technologies to compete,” said Jeyakumar, agreeing with Murray’s concerns. “These are all solvable problems but we need to work on them now.”
 

'2035 IS TOMORROW'
According to Bentley, the former Ontario energy minister-turned academic, “the government's role is to match the aspiration with the means to achieve that aspiration.”

“We have spent far more time as governments talking about the goals and the high-level promises [of a net-zero electricity grid by 2035] without spending as much time as we need to in order to recognize what a massive transformation this will mean,” Bentley said. “It is easy to talk about the end-goal, but how do you get there?”

The Canadian Electricity Assocation’s Bradley agreed “there are still a lot of outstanding questions about how we are going to turn those aspirations into actual policies. The 2035 goal is going to be very difficult to achieve in the absence of seeing exactly what the policies are that are going to move us in that direction.”

“It can take a decade to go through the processes of consultations and planning and then building and getting online,” Bradley said. “Particularly when you’re talking about big electricity projects, 2035 is tomorrow.”

Jeyakumar said “we cannot afford to wait any longer” for policies to be put in place as the decisions governments make today “will then lock us in for the next 30 or 40 years into specific technologies.”

“We need to consider it like saving for retirement,” said Gorman of the Canadian Nuclear Association. “Every year that you don’t contribute to your retirement savings just pushes your retirement one more year into the future.”

Metering Pilot projects may be good example for Ontario utilities

Ontario Electricity Pricing Pilot Projects explore alternative rates beyond time-of-use, with LDCs and the Ontario Energy Board testing dynamic pricing, demand management, smart-meter billing, and residential customer choice to enhance service and energy efficiency.

 

Key Points

Ontario LDC trials testing alternatives to time-of-use rates to improve billing, demand response, and efficiency.

✅ Data shared across LDCs and Ontario Energy Board provincewide

✅ Tests dynamic pricing, peak/off-peak plans, demand management

✅ Insights to enhance customer choice, bills, and energy savings

 

The results from three electricity pilot projects being offered in southern Ontario will be valuable to utility companies across the province.

Ontario Energy Minister Glenn Thibeault was in Barrie on Tuesday to announce the pilot projects, which will explore alternative pricing plans for electricity customers from three different utility companies, informed by the electricity cost allocation framework guiding rate design.

"Everyone in the industry is watching to see how the pilots deliver.", said Wendy Watson, director of communications for Greater Sudbury Utilities.

"The data will be shared will all the LDCs [local distribution companies] in the province, and probably beyond...because the industry tends to share that kind of information."

Most electricity customers in the province are billed using time-of-use rates, including options like the ultra-low overnight rates that lower costs during off-peak periods, where the cost of electricity varies depending on demand.

The Ontario Energy Board said in a media release that the projects will give residential customers more choice in how much they pay for electricity at different times, reflecting changes for Ontario electricity consumers that expand plan options.

Pilot projects can help improve service

Watson says these kinds of projects give LDCs the chance to experiment and explore new ways of delivering their service, including demand-response initiatives like the Peak Perks program that encourage conservation.

"Any pilot project is a great way to see if in practice if the theory proves out, so I think it's great that the province is supporting these LDCs," she says.

GSU recently completed its own pilot project, the Home Energy Assessment and Retrofit (HEAR) program, which focused on customers who use electric baseboards to heat their homes, amid broader provincial support for electric bills to ease costs."We installed some measures, like programmable thermostats and a few other pieces of equipment into their house," Watson says. "We also made some recommendations about other things that they could do to make their homes more energy efficient."

At the end of the program, GSU provided customers with a report so that they could the see the overall impact on their energy consumption.

Watson says a report on the results of the HEAR program will be released in the near future, for other LDCs interested in new ways to improve their service.

"We think it's incumbent on every LDC...to see what ideas that they can come up with and get approved so they can best serve their customers."

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.

Energy Security Support to Ukraine

U.S. Energy Aid to Ukraine delivers emergency electricity grid equipment, generators, transformers, and circuit breakers, supports ENTSO-E integration, strengthens energy security, and advances decarbonization to restore power and heat amid Russian attacks.

 

Key Points

U.S. funding and equipment stabilize Ukraine's power grid, strengthen energy security, and advance ENTSO-E integration.

✅ $53M for transformers, breakers, surge arresters, disconnectors

✅ $55M for generators and emergency heat to municipalities

✅ ENTSO-E integration, cybersecurity, nuclear safety support

 

In the midst of Russia’s continued brutal attacks against Ukraine’s energy infrastructure, Secretary of State Blinken announced today during a meeting of the G7+ on the margins of the NATO Ministerial in Bucharest that the United States government is providing over $53 million to support acquisition of critical electricity grid equipment. This equipment will be rapidly delivered to Ukraine on an emergency basis to help Ukrainians persevere through the winter, as the country prepares for winter amid energy challenges. This supply package will include distribution transformers, circuit breakers, surge arresters, disconnectors, vehicles and other key equipment.

This new assistance is in addition to $55 million in emergency energy sector support for generators and other equipment to help restore emergency power and heat to local municipalities impacted by Russia’s attacks on Ukraine’s power system, while both sides accuse each other of energy ceasefire violations that complicate repairs. We will continue to identify additional support with allies and partners, and we are also helping to devise long-term solutions for grid restoration and repair, along with our assistance for Ukraine’s effort to advance the energy transition and build an energy system decoupled from Russian energy.

Since Russia’s further invasion on February 24, working together with Congress, the Administration has provided nearly $32 billion in assistance to Ukraine, including $145 million to help repair, maintain, and strengthen Ukraine’s power sector in the face of continued attacks. We also have provided assistance in areas such as EU integration and regional electricity trade, including electricity imports to stabilize supply, natural gas sector support to maximize resource development, support for nuclear safety and security, and humanitarian relief efforts to help Ukrainians to overcome the impacts of energy shortages.

Since 2014, the United States has provided over $160 million in technical support to strengthen Ukraine’s energy security, including to strengthen EU interconnectivity, increase energy supply diversification, and promote investments in energy efficiency, renewable energy, and clean energy technologies and innovation.  Much of this support has helped prepare Ukraine for its eventual interconnection with Europe’s ENTSO-E electricity grid, aligning with plans to synchronize with ENTSO-E across the integrated power system, including the island mode test in February 2022 that not only demonstrated Ukraine’s progress in meeting the EU’s technical requirements, but also proved to be critical considering Russia’s subsequent military activity aimed at disrupting power supplies and distribution in Ukraine.

 

Department of Energy (DOE)

  • With the increased attacks on Ukraine’s electricity grid and energy infrastructure in October, DOE worked with the Ukrainian Ministry of Energy and DOE national laboratories to collate, vet, and help prioritize lists of emergency electricity equipment for grid repair and stabilization amid wider global energy instability affecting supply chains.
  • Engaged at the CEO level U.S. private sector and public utilities and equipment manufacturers to identify $35 million of available electricity grid equipment in the United States compatible with the Ukrainian system for emergency delivery. Identified $17.5 million to support purchase and transportation of this equipment.
  • With support from Congress, initiated work on full integration of Ukraine with ENTSO-E to support resumption of Ukrainian energy exports to other European countries in the region, including funding for energy infrastructure analysis, collection of satellite data and analysis for system mapping, and work on cyber security, drawing on the U.S. rural energy security program to inform best practices.
  • Initiated work on a new dynamic model of interdependent gas and power systems of Europe and Ukraine to advance identification and mitigation of critical vulnerabilities.
  • Delivered emergency diesel fuel and other critical materials needed for safe operation of Ukrainian nuclear power plants, as well as initiated the purchase of three truck-mounted emergency diesel backup generators to be delivered to improve plant safety in the event of the loss of offsite power.

U.S. Department of State

  • Building on eight years of technical engagement, the State Department continued to provide technical support to Naftogaz and UkrGasVydobuvannya to advance corporate governance reform, increase domestic gas production, provide strategic planning, and assess critical sub-surface and above-ground technical issues that impact the company’s core business functions.
  • The State Department is developing new programs focused on emissions abatement, decarbonization, and diversification, acknowledging the national security benefits of reducing reliance on fossil fuels to support Ukraine’s ambitious clean energy and climate goals and address the impacts of reduced supplies of natural gas from Russia.
  • The State Department led a decades-long U.S. government engagement to develop and expand natural gas reverse flow (west-to-east) routes to enhance European and Ukrainian energy security. Ukraine is now able to import natural gas from Europe, eliminating the need for Ukraine to purchase natural gas from Gazprom.
