Duke Energy has asked federal regulators to allow a temporary cooling-water system at the Allen power plant in Gaston County, allowing the plant to operate at full tilt through the late-summer drought.

Allen pulls millions of gallons a day from Lake Wylie and uses it to condense steam inside the coal-fueled plant. The warmed water is then piped into a canal where it cools before flowing into the South Fork of the Catawba River.

Drought makes it harder to cool the discharged water, which must be below 102 degrees before flowing back into the lake. Little water flows into Wylie from tributaries and Duke releases less water from its dam, reducing the circulation of fresh water in the lake. That problem could limit the amount of power that Allen, one of Duke's largest plants at 1,140 megawatts, can produce.

Demand for electricity is highest in summer, when air conditioners kick in around the region. Duke's solution: Draw 86 million more gallons a day from the lake to the canal. The 11 percent increase of cooler water would further dilute the warm discharge water. The utility applied Friday to the Federal Energy Regulatory Commission for permission to use the temporary system through September.

Without it, said Joe Hall, Duke's lake-services director, Allen might have to curtail its operations. The N.C. Division of Water Quality, which polices Duke's discharges to the lake, has already approved the request.

Next year, Duke plans to install a permanent system to bring in more cooling water each summer from July through September, allowing the plant to make more power. Since the drought took hold more than a year ago, Duke has sharply reduced operation of its hydroelectric power plants to conserve water in its lakes.

Earlier this year, the utility reconfigured its McGuire nuclear plant to allow Lake Norman to be reduced three feet below its previous minimum level. Duke also took an option to buy up to 520 megawatts of power from a natural gas-powered plant in South Carolina if its own plants can't run.

Zero-emission electricity in Canada by 2035 is practical and profitable

Canada 100% Renewable Power by 2035 envisions a decentralized grid built on wind, solar, energy storage, and efficiency, delivering zero-emission, resilient, low-cost electricity while phasing out nuclear and gas to meet net-zero targets.

 

Key Points

Zero-emission, decentralized grid using wind, solar, and storage, plus efficiency, to retire fossil and nuclear by 2035.

✅ Scale wind and solar 18x with storage for reliability.

✅ Phase out nuclear and gas; no CCS or offsets needed.

✅ Modernize grids and codes; boost efficiency, jobs, and affordability.

 

A powerful derecho that left nearly a million people without power in Ontario and Quebec on May 21 was a reminder of the critical importance of electricity in our daily lives.

Canada’s electrical infrastructure could be more resilient to such events, while being carbon-emission free and provide low-cost electricity with a decentralized grid powered by 100 per cent renewable energy, according to a new study from the David Suzuki Foundation (DSF), a vision of an electric, connected and clean future if the country chooses.

This could be accomplished by 2035 by building a lot more solar and wind, despite indications that demand for solar electricity has lagged in Canada, adding energy storage, while increasing the energy efficiency in buildings, and modernizing provincial energy grids. As this happens, nuclear energy and gas power would be phased out. There would also be no need for carbon capture and storage nor carbon offsets, the modeling study concluded.

“Solar and wind are the cheapest sources of electricity generation in history,” said study co-author Stephen Thomas, a mechanical engineer and climate solutions policy analyst at the DSF.

“There are no technical barriers to reaching 100 per cent zero-emission electricity by 2035 nationwide,” Thomas told The Weather Network (TWN). However, there are considerable institutional and political barriers to be overcome, he said.

Other countries face similar barriers and many have found ways to reduce their emissions; for example, the U.S. grid's slow path to 100% renewables illustrates these challenges. There are enormous benefits including improved air quality and health, up to 75,000 new jobs annually, and lower electricity costs. Carbon emissions would be reduced by 200 million tons a year by 2050, just over one quarter of the reductions needed for Canada to meet its overall net zero target, the study stated.

Building a net-zero carbon electricity system by 2035 is a key part of Canada’s 2030 Emissions Reduction Plan. Currently over 80 per cent of the nation’s electricity comes from non-carbon sources including a 15 per cent contribution from nuclear, with solar capacity nearing a 5 GW milestone nationally. How the final 20 per cent will be emission-free is currently under discussion.

The Shifting Power study envisions an 18-fold increase in wind and solar energy, with the Prairie provinces expected to lead growth, along with a big increase in Canada’s electrical generation capacity to bridge the 20 per cent gap as well as replacing existing nuclear power.

The report does not see a future role for nuclear power due to the high costs of refurbishing existing plants, including the challenges with disposal of radioactive wastes and decommissioning plants at their end of life. As for the oft-proposed small modular nuclear reactors, their costs will likely “be much more costly than renewables,” according to the report.

There are no technical barriers to building a bigger, cleaner, and smarter electricity system, agrees Caroline Lee, co-author of the Canadian Climate Institute’s study on net-zero electricity, “The Big Switch” released in May. However, as Lee previously told TWN, there are substantial institutional and political barriers.

In many respects, the Shifting Power study is similar to Lee’s study except it phases out nuclear power, forecasts a reduction in hydro power generation, and does not require any carbon capture and storage, she told TWN. Those are replaced with a lot more wind generation and more storage capacity.

“There are strengths and weaknesses to both approaches. We can do either but need a wide debate on what kind of electricity system we want,” Lee said.

That debate has to happen immediately because there is an enormous amount of work to do. When it comes to energy infrastructure, nearly everything “we put in the ground has to be wind, solar, or storage” to meet the 2035 deadline, she said.

There is no path to net zero by 2050 without a zero-emissions electricity system well before that date. Here are some of the necessary steps the report provided:

Create a range of skills training programs for renewable energy construction and installation as well as building retrofits.

Prioritize energy efficiency and conservation across all sectors through regulations such as building codes.

Ensure communities and individuals are fully informed and can decide if they wish to benefit from hosting energy generation infrastructure.

Create a national energy poverty strategy to ensure affordable access.

Strong and clear federal and provincial rules for utilities that mandate zero-emission electricity by 2035.

For Indigenous communities, make sure ownership opportunities are available along with decision-making power.

Canada should move as fast as possible to 100 per cent renewable energy to gain the benefits of lower energy costs, less pollution, and reduced carbon emissions, says Stanford University engineer and energy expert Mark Jacobson.

“Canada has so many clean, renewable energy resources that it is one of the easier countries [that can] transition away from fossil fuels,” Jacobson told TWN.

For the past decade, Jacobson has been producing studies and technical reports on 100 per cent renewable energy, including a new one for Canada, even as Canada is often seen as a solar power laggard today. The Stanford report, A Solution to Global Warming, Air Pollution, and Energy Insecurity for Canada, says a 100 per cent transition by 2035 timeline is ideal. Where it differs from DSF’s Shifting Power report is that it envisions offshore wind and rooftop solar panels which the latter did not.

“Our report is very conservative. Much more is possible,” agrees Thomas.

“We’re lagging behind. Canadians really want to get going on building solutions and getting the benefits of a zero emissions electricity system.”

Texas produces and consumes the most electricity in the US

Texas ERCOT Power Grid leads U.S. wind generation yet faces isolated interconnection, FERC exemption, and high industrial energy use, with distinct electricity and natural gas prices managed by a single balancing authority.

 

Key Points

The state-run interconnection that balances Texas electricity, isolated from FERC oversight and other U.S. grids.

✅ Largest U.S. wind power producer, high industrial demand

✅ Operates one balancing authority, independent interconnection

✅ Pays lower electricity, higher natural gas vs national average

 

For nearly two decades, the Lone Star State has generated more wind-sourced electricity than any other state in the U.S., according to the Energy Information Administration, or EIA.

In 2022, EIA reported Texas produced more electricity than any other state and generated twice as much as second-place Florida.

However, Texas also leads the country in another category. According to EIA, Texas is the largest energy-consuming state in the nation across all sectors with more than half of the state’s energy being used by the industrial sector.

As of May 2023, Texas residents paid 43% more for natural gas and around 10% less for electricity compared to the national average, according to EIA, and in competitive areas shopping for electricity is getting cheaper as well. Commercial and industrial sectors on average for the same month paid 25% less for electricity compared to the national average.


U.S. electric system compared to Texas
The U.S. electric system is essentially split into three regions called interconnections and are managed by a total of 74 entities called balancing authorities that ensure that power supply and demand are balanced throughout the region to prevent the possibility of blackouts, according to EIA.

The three regions (Interconnections):

Eastern Interconnection: Covers all U.S. states east of the Rocky Mountains, a portion of northern Texas, and consists of 36 balancing authorities.
Western Interconnection: Covers all U.S. states west of the Rockies and consists of 37 balancing authorities.
ERCOT: Covers the majority of Texas and consists of one balancing authority (itself).

During the 2021 winter storm, Texas electric cooperatives were credited with helping maintain service in many communities.

“ERCOT is unique in that the balancing authority, interconnection, and the regional transmission organization are all the same entity and physical system,” according to EIA, a structure often discussed in analyses of Texas power grid challenges today.

With this being the case, Texas is the only state in the U.S. that balances itself, the only state that is not subject to the jurisdiction of the Federal Energy Regulatory Commission, or FERC, and the only state that is not synchronously interconnected to the grid in the rest of the United States in the event of tight grid conditions, highlighting ongoing discussions about improving Texas grid reliability before peak seasons, according to EIA.

Every other state in the U.S. is connected to a web of multiple balancing authorities that contribute to ensuring power supply and demand are met.

California, for example, was the fourth largest electricity producer and the third largest electricity consumer in the nation in 2022, according to EIA, and California imports the most electricity from other states while Pennsylvania exports the most.

Although California produces significantly less electricity than Texas, it has the ability to connect with more than 10 neighboring balancing authorities within the Western Interconnection to interchange electricity, a dynamic that can see clean states importing dirty electricity under certain market conditions. ERCOT being independent only has electricity interchange with two balancing authorities, one of which is in Mexico.

Regardless of Texas’ unique power structure compared to the rest of the nation, the vast majority of the U.S. risked electricity supplies during this summer’s high heat, as outlined in severe heat blackout risks reports, according to EIA.

Share of coal in UK's electricity system falls to record lows

UK Coal Phase-Out marks record-low coal generation as the UK grid shifts to renewable power, wind farms, and a net zero trajectory, slashing carbon emissions and supporting cleaner EV charging across the electricity system.

 

Key Points

UK Coal Phase-Out ends coal-fired electricity nationwide, powered by renewables and net zero policy to cut grid carbon.

✅ Coal's Q2 share fell to 0.7%, a record low

✅ Renewables up 12% with Beatrice wind farm

✅ EV charging grows cleaner as grid decarbonizes

 

The share of coal in the UK’s electricity system has fallen to record lows in recent months, alongside a coal-free power record, according to government data.

The figures show electricity generated by the UK’s most polluting power plants made up an average of 0.7% of the total in the second quarter of this year, a shift underway since wind first outpaced coal in 2016 across the UK. The amount of coal used to power the electricity grid fell by almost two-thirds compared with the same months last year.

A government spokesperson said coal-generated energy “will soon be a distant memory” as the UK moves towards becoming a net zero emissions economy, despite signs that low-carbon generation stalled in 2019 in some analyses.

“This new record low is a result of our world-leading low-carbon energy industry, which provided more than half of our energy last year and continues to go from strength to strength as we aim to end our contribution to climate change entirely by 2050,” the spokesperson said.

The UK electricity market is on track to end coal power after 142 years by the government’s target date of 2025.

This year three major energy companies have announced plans to close coal-fired power plants in the UK, which would leave only four remaining after the coming winter, ahead of the last coal power station going offline nationwide.

RWE said this month it would close the Aberthaw B power station in south Wales, its last UK coal plant, after the winter. SSE will close the Fiddler’s Ferry plant near Warrington, Cheshire, in March 2020, and EDF Energy will shutter the Cottam coal plant in September.

So far this year the UK has gone more than 3,000 hours without using coal for power, including a full week without coal earlier in the year – nearly five times more than the whole of 2017.

Meanwhile, the government’s data shows that renewable energy climbed by 12% from the second quarter of last year, boosted by the startup of the Beatrice windfarm in the Moray Firth in Scotland, and the UK leading the G20 in wind power share in recent assessments.

The cleaner power system could accelerate carbon savings from the UK’s roads, too, as more drivers opt for electric vehicles. A study by Imperial College London for the energy company Drax found that the UK’s increasingly low-carbon energy system meant electric cars were a greener option even when taking into account the carbon emissions produced by making car batteries.

Dr Iain Staffell, of Imperial College London, said: “An electric vehicle in the UK simply cannot be more polluting than its petrol or diesel equivalent – even when taking into account the upfront carbon cost of manufacturing their batteries. Any EV bought today could be emitting just a tenth of what a petrol car would in as little as five years’ time, as the electricity it uses to charge comes from an increasingly low-carbon mix.”

German renewables deliver more electricity than coal and nuclear power for the first time

Germany renewable energy milestone 2019 saw wind, solar, hydropower, and biomass outproduce coal and nuclear, as low gas prices and high CO2 costs under the EU ETS reshaped the electricity mix, per Fraunhofer ISE.

 

Key Points

It marks H1 2019 when renewables supplied 47.3% of Germany's electricity, surpassing coal and nuclear.

✅ Driven by high CO2 prices and cheap natural gas

✅ Wind and solar output rose; coal generation declined sharply

✅ Flexible gas plants outcompeted inflexible coal units

 

In Lippendorf, Saxony, the energy supplier EnBW is temporarily taking part of a coal-fired power plant offline. Not because someone ordered it — it simply wasn't paying off. Gas prices are low, CO2 prices are high, and with many hours of sunshine and wind, renewable methods are producing a great deal of electricity as part of Germany's energy transition now reshaping operations. And in the first half of the year there was plenty of sun and wind.

The result was a six-month period in which renewable energy sources, a trend echoed by the EU wind and solar record across the bloc, produced more electricity than coal and nuclear power plants together. For the first time 47.3% of the electricity consumers used came from renewable sources, while 43.4% came from coal-fired and nuclear power plants.

In addition to solar and wind power, renewable sources also include hydropower and biomass. Gas supplied 9.3%, reflecting how renewables are crowding out gas across European power markets, while the remaining 0.4% came from other sources, such as oil, according to figures published by the Fraunhofer Institute for Solar Energy Systems in July.

Fabian Hein from the think tank Agora Energiewende stresses that the situation is only a snapshot in time, with grid expansion woes still shaping outcomes. For example, the first half of 2019 was particularly windy and wind power production rose by around 20% compared to the first half of 2018.

Electricity production from solar panels rose by 6%, natural gas by 10%, while the share of nuclear power in German electricity consumption has remained virtually unchanged despite a nuclear option debate in climate policy.

Coal, on the other hand, declined. Black coal energy production fell by 30% compared to the first half of 2018, lignite fell by 20%. Some coal-fired power plants were even taken off the grid, even as coal still provides about a third of Germany's electricity. It is difficult to say whether this was an effect of the current market situation or whether this is simply part of long-term planning, says Hein.

 

Activists storm German mine in anti-coal protest

It is clear, however, that an increased CO2 price has made the ongoing generation of electricity from coal more expensive. Gas-fired power plants also emit CO2, but less than coal-fired power plants. They are also more efficient and that's why gas-fired power plants are not so strongly affected by the CO2 price

The price is determined at a European level and covers power plants and energy intensive industries in Europe. Other areas, such as heating or transport are not covered by the CO2 price scheme. Since a reform of CO2 emissions trading in 2017, the price has risen sharply. Whereas in September 2016 it was just over €5 ($5.6), by the end of June 2019 it had climbed to over €26.

 

Ups and downs

Gas as a raw material is generally more expensive than coal. But coal-fired power plants are more expensive to build. This is why operators want to run them continuously. In times of high demand, and therefore high prices, gas-fired power plants are generally started up, as seen when European power demand hit records during recent heatwaves, since it is worth it at these times.

Gas-fired power plants can be flexibly ramped up and down. Coal-fired power plants take 11 hours or longer to get going. That's why they can't be switched on quickly for short periods when prices are high, like gas-fired power plants. In the first half of the year, however, coal-fired power plants were also ramped up and down more often because it was not always worthwhile to let the power plant run around the clock.

Because gas prices were particularly low in the first half of 2019, some gas-fired power plants were more profitable than coal-fired plants. On June 29, 2019, the gas price at the Dutch trading point TTF was around €10 per megawatt hour. A year earlier, it had been almost €20. This is partly due to the relatively mild winter, as there is still a lot of gas in reserve, confirmed a spokesman for the Federal Association of the Energy and Water Industries (BDEW). There are also several new export terminals for liquefied natural gas. Additionally, weaker growth and trade wars are slowing demand for gas. A lot of gas comes to Europe, where prices are still comparatively high, reported the Handelsblatt newspaper.

The increase in wind and solar power and the decline in nuclear power have also reduced CO2 emissions. In the first half of 2019, electricity generation emitted around 15% less CO2 than in the same period last year, reported BDEW. However, the association demands that the further expansion of renewable energies should not be hampered. The target of 65% renewable energy can only be achieved if the further expansion of renewable energy sources is accelerated.

Power Outage Disrupts Morning Routine for Thousands in London

London, Ontario Power Outage disrupts the electricity grid, causing a citywide blackout, stalled commuters, dark traffic signals, and closed businesses, as London Hydro crews race restoration after a transformer malfunction and infrastructure failures.

 

Key Points

A blackout caused by a transformer malfunction, disrupting commuters, businesses, and traffic across London, Ontario.

✅ Traffic signals dark; delays and congestion citywide

✅ London Hydro crews repairing malfunctioning transformer

✅ Businesses closed; transit routes delayed and rerouted

 

A widespread power outage early Monday morning left thousands of residents in London, Ontario, without electricity, causing significant disruption for commuters and businesses at the start of the workday. The outage, which affected several neighborhoods across the city, lasted for hours, creating a chaotic morning as residents scrambled to adjust to the unexpected interruption.

The Outage Strikes

The power failure was first reported at approximately 6:30 a.m., catching many off guard as they began their day. The affected areas included several busy neighborhoods, with power lines down and substations impacted, issues that windstorms often exacerbate for utilities. Early reports indicated that the outage was caused by a combination of issues, including technical failures and possible equipment malfunctions. London Hydro, the city's primary electricity provider, responded quickly to the situation, assuring residents that crews were dispatched to restore power as soon as possible.

"Crews are on site and working hard to restore power to those affected," a spokesperson for London Hydro said. "We understand the frustration this causes and are doing everything we can to get the power back on as soon as possible."

Impact on Commuters and Businesses

The power outage had an immediate impact on the morning commute. Traffic lights across the affected areas were down, leading to delays and rush-hour disruptions at major intersections. Drivers were forced to navigate through intersections without traffic control, creating an additional layer of complexity for those trying to get to work or school.

Public transit was also affected, with some bus routes delayed due to the power loss at key transit stations. The situation added further stress to commuters already dealing with the challenges of a typical Monday morning rush.

Businesses in the affected neighborhoods faced a variety of challenges. Some were forced to close early or delay their opening hours due to a lack of electricity. Many shops and offices struggled with limited access to the internet and phone lines, which hindered their ability to process orders and serve customers. Local coffee shops, often a go-to for busy workers, were also unable to operate their coffee machines or provide basic services, forcing customers to go without their usual morning caffeine fix.

"For a lot of people, it's their first stop in the morning," said one local business owner. "It’s frustrating because we rely on power to function, and with no warning, we had to turn away customers."

The Response

As the hours ticked by, residents were left wondering when the power would return. London Hydro’s social media accounts were filled with updates, keeping residents informed about the restoration efforts, a practice echoed when BC Hydro crews responded during an atypical storm. The utility company urged those who were experiencing issues to report them online to help prioritize repair efforts.

"We are aware that many people are affected, and our teams are working tirelessly to restore power," the utility posted on Twitter. "Please stay safe, and we thank you for your patience."

Throughout the morning, the power was gradually restored to different areas of the city. However, some parts remained without electricity well into the afternoon, a situation reminiscent of extended outages that test city resilience. London Hydro confirmed that the outage was caused by a malfunctioning transformer, and the necessary repairs would take time to complete.

Long-Term Effects and Community Concerns

While the immediate effects of the outage were felt most acutely during the morning hours, some residents expressed concern about the potential long-term effects. The city’s reliance on a stable electricity grid became a focal point of discussion, with many wondering if similar outages could occur in the future, as seen in the North Seattle outage earlier this year.

"I understand that things break, but it’s frustrating that it took so long for power to come back," said a London resident. "This isn’t the first time something like this has happened, and it makes me wonder about the reliability of our infrastructure."

City officials responded by reassuring residents that efforts are underway to upgrade the city's infrastructure to prevent such outages from happening in the future. A report released by London Hydro highlighted ongoing investments in upgrading transformers and other key components of the city's power grid. Province-wide, Hydro One restored power to more than 277,000 customers after damaging storms, underscoring the scale of upgrades needed. Despite these efforts, however, experts warn that older infrastructure in some areas may still be vulnerable to failure, especially during extreme weather events or other unforeseen circumstances.

The morning outage serves as a reminder of how reliant modern cities are on stable electricity networks. While the response from London Hydro was swift and effective in restoring power, it’s clear that these types of events can cause significant disruptions to daily life. As the city moves forward, many are calling for increased investment in infrastructure and proactive measures to prevent future outages, especially after Toronto outages persisted following a spring storm in the region.

In the meantime, Londoners have adapted, finding ways to go about their day as best they can. For some, it’s a reminder of the importance of preparedness in an increasingly unpredictable world. Whether it’s an extra flashlight or a backup power source, residents are learning to expect the unexpected and be ready for whatever the next workday might bring.

Ontario plunging into energy storage as electricity supply crunch looms

Ontario Energy Storage Procurement accelerates grid flexibility as IESO seeks lithium batteries, pumped storage, compressed air, and flywheels to balance renewables, support EV charging, and complement gas peakers during Pickering refits and rising electricity demand.

 

Key Points

Ontario's plan to procure 2,500 MW of storage to firm renewables, aid EV charging, and add flexible grid capacity.

✅ 2,500 MW storage plus 1,500 MW gas for 2025-2027 reliability

✅ Mix: lithium batteries, pumped storage, compressed air, flywheels

✅ Enables VPPs via EVs, demand response, and hybrid solar-storage

 

Ontario is staring down an electricity supply crunch and amid a rush to secure more power, it is plunging into the world of energy storage — a relatively unknown solution for the grid that experts say could also change energy use at home.

Beyond the sprawling nuclear plants and waterfalls that generate most of the province’s electricity sit the batteries, the underground caverns storing compressed air to generate electricity, and the spinning flywheels waiting to store energy at times of low demand and inject it back into the system when needed.

The province’s energy needs are quickly rising, with the proliferation of electric vehicles and growing Canada-U.S. collaboration on EV adoption, and increasing manufacturing demand for electricity on the horizon just as a large nuclear plant that supplies 14 per cent of Ontario’s electricity is set to be retired and other units are being refurbished.

The government is seeking to extend the life of the Pickering Nuclear Generating Station, planning an import agreement for power with Quebec, rolling out conservation programs, and — controversially — relying on more natural gas to fill the looming gap between demand and supply, amid Northern Ontario sustainability debates.

Officials with the Independent Electricity System Operator say a key advantage of natural gas generation is that it can quickly ramp up and down to meet changes in demand. Energy storage can provide that same flexibility, those in the industry say.

Energy Minister Todd Smith has directed the IESO to secure 1,500 megawatts of new natural gas capacity between 2025 and 2027, along with 2,500 megawatts of clean technology such as energy storage that can be deployed quickly, which together would be enough to power the city of Toronto.

It’s a far cry from the 54 megawatts of energy storage in use in Ontario’s grid right now.

Smith said in an interview that it’s the largest active procurement for energy storage in North America.

“The one thing that we want to ensure that we do is continue to add clean generation as much as possible, and affordable and clean generation that’s reliable,” he said.

Rupp Carriveau, director of the Environmental Energy Institute at the University of Windsor, said the timing is good.

“The space is there, the technology is there, and the willingness among private industry to respond is all there,” he said. “I know of a lot of companies that have been rubbing their hands together, looking at this potential to construct storage capacity.”

Justin Rangooni, the executive director of Energy Storage Canada, said because of the relatively tight timelines, the 2,500 megawatts is likely to be mostly lithium batteries. But there are many other ways to store energy, other than a simple battery.

“As we get to future procurements and as years pass, you’ll start to see possibly pump storage, compressed air, thermal storage, different battery chemistry,” he said.

Pump storage involves using electricity during off-peak periods to pump water into a reservoir and slowly releasing it to run a turbine and generate electricity when it’s needed. Compressed air works similarly, and old salt caverns in Goderich, Ont., are being used to store the compressed air.

In thermal storage, electricity is used to heat water when demand is low and when it’s needed, water stored in tanks can be used as heat or hot water.

Flywheels are large spinning tops that can store kinetic energy, which can be used to power a turbine and produce electricity. A flywheel facility in Minto, Ont., also installed solar panels on its roof and became the first solar storage hybrid facility in Ontario, said a top IESO official.

Katherine Sparkes, the IESO’s director of innovation, research and development, said it’s exciting, from a grid perspective.

“As we kind of look to the future and we think about gas phase out and electrification, one of the big challenges that all power systems across North America and around the world are looking at is: how do you accommodate increasing amounts of variable, renewable resources and just make better use of your grid assets,” she said.

“Hybrids, storage generation pairings, gives you that opportunity to deal with the variability of renewables, so to store electricity when the sun isn’t shining, or the wind isn’t blowing, and use it when you need it to.”

The small amount of storage already in the system provides more fine tuning of the electricity system, whereas 2,500 megawatts will be a more “foundational” part of the toolkit, said Sparkes.

But what’s currently on the grid is far from the only storage in the province. Many commercial and industrial consumers, such as large manufacturing facilities or downtown office buildings, are using storage to manage their electricity usage, relying on battery energy when prices are high.

The IESO sees that as an opportunity and has changed market rules to allow those customers to sell electricity back to the grid when needed.

As well, the IESO has its eye on the thousands of mobile batteries in electric vehicles, a trend seen in California, that shuttle people around the province every day but sit unused for much of the time.

“If we can enable those batteries to work together in aggregation, or work with other types of technologies like solar or smart building systems in a configuration, like a group of technologies, that becomes a virtual power plant,” Sparkes said.

Peak Power, a company that seeks to “make power plants obsolete,” is running a pilot project with electric vehicles in three downtown Toronto office buildings in which the car batteries can provide electricity to reduce the facility’s overall demand during peak periods using vehicle-to-building charging with bidirectional chargers.

In that model, one vehicle can earn $8,000 per year, said cofounder and chief operating officer Matthew Sachs.

“Battery energy storage will change the energy industry in the same way and for the same reasons that refrigeration changed the milk industry,” he said.

“As you had refrigeration, you could store your commodity and that changed the distribution channels of it. So I believe that energy storage is going to radically change the distribution channels of energy.”

If every home has a solar panel, an electric vehicle and a residential battery, it becomes a generating station, a decentralization that’s not only more environmentally friendly, but also relies less on “monopolized utilities,” Sachs said.

In the next decade, energy demand from electric vehicles is projected to skyrocket, making vehicle-to-grid integration increasingly relevant, and Sachs said the grid can’t grow enough to accommodate a peak demand of hundreds of thousands of vehicles being plugged in to charge at the end of the workday commute. Authorities need to be looking at more incentives such as time-of-use pricing and price signals to ensure the demand is evened out, he said.

“It’s a big risk as much as it’s a big opportunity,” he said. “If we do it wrong, it will cost us billions to fix. If we do it right, it can save us billions.”

Jack Gibbons, the chair of the Ontario Clean Air Alliance, said the provincial and federal governments need to fund and install bidirectional chargers in order to fully take advantage of electric vehicles.

“This is a huge missed opportunity,” he said.
