Ontario Electricity Policy debates rates, subsidies, renewables, nuclear baseload, and Quebec hydro imports, highlighting grid transmission limits, community consultation, conservation, and the province's energy mix after cancelled wind projects and rising costs to taxpayers.

Key Points

Ontario Electricity Policy guides rates, generation, grid planning, subsidies and imports for reliable, low-cost power.

✅ Focuses on rates, subsidies, and consumer affordability

✅ Balances nuclear baseload, renewables, and Quebec hydro imports

✅ Emphasizes grid transmission, consultation, and conservation

When Kathleen Wynne’s Liberals went down to defeat at the hands of Doug Ford and the Progressive Conservatives, Ontario electricity had a lot to do with it. That was in 2018. Now, two years later, Ford’s government has electricity issues of its own, including a new stance on wind power that continues to draw scrutiny.

Electricity is politically fraught in Ontario. It’s among the most expensive in Canada. And it has been mismanaged at least as far back as nuclear energy cost overruns starting in the 1980s.

From the start Wynne’s government was tainted by the gas plant scandal of her predecessor Dalton McGuinty and then she created her own with the botched roll-out of her green energy plan. And that helped Ford get elected promising to lower electricity prices. But, rates haven’t gone down under Ford while the cost to the government coffers for subsidizing them have soared - now costing $5.6 billion a year.

Meanwhile, Ford’s government has spent at least $230 million to tear up green energy contracts signed by the former Liberal government, including two wind-farm projects that were already mid-construction.

Lessons learned?
In the final part of a three-part series, the six candidates vying to become the next leader of the Ontario Liberals discuss the province's electricity system, including the lessons learned from the prior Liberal government's botched attempts to fix it that led to widespread local opposition to a string of wind power projects, and whether they'd agree to import more hydroelectricity from Quebec.

“We had the right idea but didn’t stick the landing,” said Steven Del Duca, a member of the former Wynne government who lost his Vaughan-area seat in 2018, referring to its green-energy plan. “We need to make sure that we work more collaboratively with local communities to gain the buy-in needed to be successful in this regard.”

“Consultation and listening is key,” agreed Mitzie Hunter, who was education minister under Kathleen Wynne and in 2018 retained her seat in the legislature representing Scarborough-Guildwood. “We must seek input from community members about investments locally,” she said. “Inviting experts in to advise on major policy is also important to make evidence-based decisions."

Michael Coteau, MPP for Don Valley East and the third leadership candidate who was a member of the former government, called for “a new relationship of respect and collaboration with municipalities.”

He said there is an “important balance to be achieved between pursuing province wide objectives for green-energy initiatives and recognizing and reflecting unique local conditions and circumstances.”

Kate Graham, who has worked in municipal public service and has not held a provincial public office, said that experts and local communities are best placed to shape decisions in the sector.

In the final part of a three-part series, Ontario's Liberal leadership contenders discuss electricity, lessons learned from the bungled rollout of previous Liberal green policy, and whether to lean more on Quebec's hydroelectricity.
“What's gotten Ontario in trouble in the past is when Queen's Park politicians are the ones micromanaging the electricity file,” she said.

“Community consultation is vitally important to the long-term success of infrastructure projects,” said Alvin Tedjo, a former policy adviser to Liberal ministers Brad Duguid and Glen Murray.

“Community voices must be heard and listened to when large-scale energy programs are going to be implemented,” agreed Brenda Hollingsworth, a personal injury lawyer making her first foray into politics.

Of the six candidates, only Coteau went beyond reflection to suggest a path forward, saying he would review the distribution of responsibilities between the province and municipalities, with the aim of empowering cities and towns.

Turn back to Quebec?
Ford’s government has also turned away from a deal signed in 2016 to import hydroelectricity from Quebec.

Graham and Hunter both said they would consider increasing such imports. Hunter noted that the deal, which would displace domestic natural gas production, will lower the cost of electricity paid by Ontario ratepayers by a net total of $38 million from 2017 to 2023, according to the province’s fiscal watchdog.

“I am open to working with our neighbouring province,” Hunter said. “This is especially important as we seek to bring electricity to remote northern, on-reserve Indigenous communities.”

Tedjo said he has no issues with importing clean energy as long as it’s at a fair price.

Hollingsworth and Coteau both said they would withhold judgment until they could see the province’s capacity status in 2022.

“In evaluating the case for increasing importation of water power from Quebec, we must realistically assess the limitations of the existing transmission system and the cost and time required to scale up transmission infrastructure, among other factors,” Coteau said.

Del Duca also took a wait-and-see approach. “This will depend on our energy needs and energy mix,” he said. “I want to see our energy needs go down; we need more efficiency and better conservation to make that happen.”

What's the right energy mix?
Nuclear energy currently accounts for about a third of Ontario’s energy-producing capacity, even as Canada explores zero-emissions electricity by 2035 pathways. But it actually supplies about 60 percent of Ontario’s electricity. That is because nuclear reactors are always on, producing so-called baseload power.

Hydroelectricity provides another 25 percent of supply, while oil and natural gas contribute 6 per cent and wind adds 7 percent. Both solar and biofuels account for less than one percent of Ontario’s energy supply. However, a much larger amount of solar is not counted in this tally, as it is used at or near the sites where it is generated, and never enters the transmission system.

Asked for their views on how large a role various sources of power should play in Ontario’s electricity mix in the future, the candidates largely backed the idea of renewable energy, but offered little specifics.

Graham repeated her statement that experts and communities should drive that conversation. Tedjo said all non-polluting technologies should play a role in Ontario’s energy mix, as provinces like Alberta demonstrate parallel growth in green energy and fossil fuels. Coteau said we need a mix of renewable-energy sources, without offering specifics.

“We also need to pursue carbon capture and sequestration, working in particular with our farming communities,” he added.

Thermoelectric Materials convert waste heat into electricity via the Seebeck effect; quantum computations and semiconductors accelerate discovery, enabling clean energy, higher efficiency, and scalable heat-to-power conversion from abundant, non-toxic, cost-effective compounds.

Key Points

Thermoelectric materials turn waste heat into electricity via the Seebeck effect, improving energy efficiency.

✅ Convert waste heat to electricity via the Seebeck effect

✅ Quantum computations rapidly identify high-performance candidates

✅ Target efficient, low-thermal-conductivity, non-toxic, abundant compounds

The need to transition to clean energy is apparent, urgent and inescapable. We must limit Earth’s rising temperature to within 1.5 C to avoid the worst effects of climate change — an especially daunting challenge in the face of the steadily increasing global demand for energy and the need for reliable clean power, with concepts that can generate electricity at night now being explored worldwide.

Part of the answer is using energy more efficiently. More than 72 per cent of all energy produced worldwide is lost in the form of heat, and advances in turning thermal energy into electricity could recover some of it. For example, the engine in a car uses only about 30 per cent of the gasoline it burns to move the car. The remainder is dissipated as heat.

Recovering even a tiny fraction of that lost energy would have a tremendous impact on climate change. Thermoelectric materials, which convert wasted heat into useful electricity, can help, especially as researchers pursue low-cost heat-to-electricity materials for scalable deployment.

Until recently, the identification of these materials had been slow. My colleagues and I have used quantum computations — a computer-based modelling approach to predict materials’ properties — to speed up that process and identify more than 500 thermoelectric materials that could convert excess heat to electricity, and help improve energy efficiency.

Making great strides towards broad applications
The transformation of heat into electrical energy by thermoelectric materials is based on the “Seebeck effect.” In 1826, German physicist Thomas Johann Seebeck observed that exposing the ends of joined pieces of dissimilar metals to different temperatures generated a magnetic field, which was later recognized to be caused by an electric current.

Shortly after his discovery, metallic thermoelectric generators were fabricated to convert heat from gas burners into an electric current. But, as it turned out, metals exhibit only a low Seebeck effect — they are not very efficient at converting heat into electricity.

In 1929, the Russian scientist Abraham Ioffe revolutionized the field of thermoelectricity. He observed that semiconductors — materials whose ability to conduct electricity falls between that of metals (like copper) and insulators (like glass) — exhibit a significantly higher Seebeck effect than metals, boosting thermoelectric efficiency 40-fold, from 0.1 per cent to four per cent.

This discovery led to the development of the first widely used thermoelectric generator, the Russian lamp — a kerosene lamp that heated a thermoelectric material to power a radio.

Are we there yet?
Today, thermoelectric applications range from energy generation in space probes to cooling devices in portable refrigerators, and include emerging thin-film waste-heat harvesters for electronics as well. For example, space explorations are powered by radioisotope thermoelectric generators, converting the heat from naturally decaying plutonium into electricity. In the movie The Martian, for example, a box of plutonium saved the life of the character played by Matt Damon, by keeping him warm on Mars.

In the 2015 film, The Martian, astronaut Mark Watney (Matt Damon) digs up a buried thermoelectric generator to use the power source as a heater.

Despite this vast diversity of applications, wide-scale commercialization of thermoelectric materials is still limited by their low efficiency.

What’s holding them back? Two key factors must be considered: the conductive properties of the materials, and their ability to maintain a temperature difference, as seen in nighttime electricity from cold concepts, which makes it possible to generate electricity.

The best thermoelectric material would have the electronic properties of semiconductors and the poor heat conduction of glass. But this unique combination of properties is not found in naturally occurring materials. We have to engineer them, drawing on advances such as carbon nanotube energy harvesters to guide design choices.

Searching for a needle in a haystack
In the past decade, new strategies to engineer thermoelectric materials have emerged due to an enhanced understanding of their underlying physics. In a recent study in Nature Materials, researchers from Seoul National University, Aachen University and Northwestern University reported they had engineered a material called tin selenide with the highest thermoelectric performance to date, nearly twice that of 20 years ago. But it took them nearly a decade to optimize it.

To speed up the discovery process, my colleagues and I have used quantum calculations to search for new thermoelectric candidates with high efficiencies. We searched a database containing thousands of materials to look for those that would have high electronic qualities and low levels of heat conduction, based on their chemical and physical properties. These insights helped us find the best materials to synthesize and test, and calculate their thermoelectric efficiency.

We are almost at the point where thermoelectric materials can be widely applied, but first we need to develop much more efficient materials. With so many possibilities and variables, finding the way forward is like searching for a tiny needle in an enormous haystack.

Just as a metal detector can zero in on a needle in a haystack, quantum computations can accelerate the discovery of efficient thermoelectric materials. Such calculations can accurately predict electron and heat conduction (including the Seebeck effect) for thousands of materials and unveil the previously hidden and highly complex interactions between those properties, which can influence a material’s efficiency.

Large-scale applications will require themoelectric materials that are inexpensive, non-toxic and abundant. Lead and tellurium are found in today’s thermoelectric materials, but their cost and negative environmental impact make them good targets for replacement.

Quantum calculations can be applied in a way to search for specific sets of materials using parameters such as scarcity, cost and efficiency, and insights can even inform exploratory devices that generate electricity out of thin air in parallel fields. Although those calculations can reveal optimum thermoelectric materials, synthesizing the materials with the desired properties remains a challenge.

A multi-institutional effort involving government-run laboratories and universities in the United States, Canada and Europe has revealed more than 500 previously unexplored materials with high predicted thermoelectric efficiency. My colleagues and I are currently investigating the thermoelectric performance of those materials in experiments, and have already discovered new sources of high thermoelectric efficiency.

Those initial results strongly suggest that further quantum computations can pinpoint the most efficient combinations of materials to make clean energy from wasted heat and the avert the catastrophe that looms over our planet.

Ontario Battery Energy Storage anchors IESO strategy, easing peak demand and boosting grid reliability. Projects like Oneida BESS (250MW) and nearly 3GW procurements integrate renewables, wind and solar, enabling flexible, decarbonized power.

Key Points

Provincewide grid batteries help IESO manage peaks, integrate renewables, and strengthen reliability across Ontario.

✅ IESO forecasts 1,000MW peak growth by 2026

✅ Oneida BESS adds 250MW with 20-year contract

✅ Nearly 3GW storage procured via LT1 and other RFPs

Ontario’s electricity grid is facing increasing demand amid a looming supply crunch, prompting the province to invest heavily in battery energy storage systems (BESS) as a key solution. The Ontario Independent Electricity System Operator (IESO) has highlighted that these storage technologies will be crucial for managing peak demand in the coming years.

Ontario's energy demands have been on the rise, driven by factors such as population growth, electric vehicle manufacturing, data center expansions, and heavy industrial activity. The IESO's latest assessment, and its work on enabling storage, covering the period from April 2025 to September 2026, indicates that peak demand will increase by approximately 1,000MW between the summer of 2025 and 2026. This forecasted rise in energy use is attributed to the acceleration of various sectors within the province, underscoring the need for reliable, scalable energy solutions.

A significant portion of this solution will be met by large-scale energy storage projects. Among the most prominent is the Oneida BESS, a flagship project that will contribute 250MW of storage capacity. This project, developed by a consortium including Northland Power and NRStor, will be located on land owned by the Six Nations of the Grand River. Expected to be operational soon, it will play a pivotal role in ensuring grid stability during high-demand periods. The project benefits from a 20-year contract with the IESO, guaranteeing payments that will support its financial viability, alongside additional revenue from participating in the wholesale energy market.

In addition to Oneida, Ontario has committed to acquiring nearly 3GW of energy storage capacity through various procurement programs. The 2023 Expedited Long-Term 1 (LT1) request for proposals (RfP) alone secured 881MW of storage, with additional projects in the pipeline. A notable example is the Hagersville Battery Energy Storage Park, which, upon completion, will be the largest such project in Canada. The success of these procurement efforts highlights the growing importance of BESS in Ontario's energy strategy.

The IESO’s proactive approach to energy storage is not only a response to rising demand but also a step toward decarbonizing the province’s energy system. As Ontario transitions away from traditional fossil fuels, BESS will provide the necessary flexibility to accommodate increasing renewable energy generation, a clean energy solution widely recognized in jurisdictions like New York, particularly from intermittent sources like wind and solar. By storing excess energy during periods of low demand and dispatching it when needed, these systems will help maintain grid stability, and as many utilities see benefits even without mandates, reduce reliance on fossil fuel-based power plants.

Looking ahead, Ontario's energy storage capacity is expected to grow significantly, complemented by initiatives such as the Hydrogen Innovation Fund, with projects from the 2023 LT1 RfP expected to come online by 2027. As more storage resources are integrated into the grid, the province is positioning itself to meet its rising energy needs while also advancing its environmental goals.

Ontario’s increasing reliance on battery energy storage is a clear indication of the province’s commitment to a sustainable and resilient energy future, aligning with perspectives from Sudbury sustainability advocates on the grid's future. With substantial investments in storage technology, Ontario is not only addressing current energy challenges but also paving the way for a cleaner, more reliable energy system in the years to come.

Near-Field Thermophotovoltaics captures radiated energy across a nanoscale gap, using thin-film photovoltaic cells and indium gallium arsenide to boost power density and efficiency, enabling compact Army portable power from emitters via radiative heat transfer.

Key Points

A nanoscale TPV method capturing near-field photons for higher power density at lower emitter temperatures.

✅ Nanoscale gap boosts radiative transfer and usable photon flux

✅ Thin-film InGaAs cells recycle sub-band-gap photons via reflector

✅ Achieved ~5 kW/m2 power density with higher efficiency

With the addition of sensors and enhanced communication tools, providing lightweight, portable power has become even more challenging, with concepts such as power from falling snow illustrating how diverse new energy-harvesting approaches are. Army-funded research demonstrated a new approach to turning thermal energy into electricity that could provide compact and efficient power for Soldiers on future battlefields.

Hot objects radiate light in the form of photons into their surroundings. The emitted photons can be captured by a photovoltaic cell and converted to useful electric energy. This approach to energy conversion is called far-field thermophotovoltaics, or FF-TPVs, and has been under development for many years; however, it suffers from low power density and therefore requires high operating temperatures of the emitter.

The research, conducted at the University of Michigan and published in Nature Communications, demonstrates a new approach, where the separation between the emitter and the photovoltaic cell is reduced to the nanoscale, enabling much greater power output than what is possible with FF-TPVs for the same emitter temperature.

This approach, which enables capture of energy that is otherwise trapped in the near-field of the emitter is called near-field thermophotovoltaics or NF-TPV and uses custom-built photovoltaic cells and emitter designs ideal for near-field operating conditions, alongside emerging smart solar inverters that help manage conversion and delivery.

This technique exhibited a power density almost an order of magnitude higher than that for the best-reported near-field-TPV systems, while also operating at six-times higher efficiency, paving the way for future near-field-TPV applications, including remote microgrid deployments in extreme environments, according to Dr. Edgar Meyhofer, professor of mechanical engineering, University of Michigan.

"The Army uses large amounts of power during deployments and battlefield operations and must be carried by the Soldier or a weight constrained system," said Dr. Mike Waits, U.S. Army Combat Capabilities Development Command's Army Research Laboratory. "If successful, in the future near-field-TPVs could serve as more compact and higher efficiency power sources for Soldiers as these devices can function at lower operating temperatures than conventional TPVs."

The efficiency of a TPV device is characterized by how much of the total energy transfer between the emitter and the photovoltaic cell is used to excite the electron-hole pairs in the photovoltaic cell, where insights from near-light-speed conduction research help contextualize performance limits in semiconductors. While increasing the temperature of the emitter increases the number of photons above the band-gap of the cell, the number of sub band-gap photons that can heat up the photovoltaic cell need to be minimized.

"This was achieved by fabricating thin-film TPV cells with ultra-flat surfaces, and with a metal back reflector," said Dr. Stephen Forrest, professor of electrical and computer engineering, University of Michigan. "The photons above the band-gap of the cell are efficiently absorbed in the micron-thick semiconductor, while those below the band-gap are reflected back to the silicon emitter and recycled."

The team grew thin-film indium gallium arsenide photovoltaic cells on thick semiconductor substrates, and then peeled off the very thin semiconductor active region of the cell and transferred it to a silicon substrate, informing potential interfaces with home battery systems for distributed use.

All these innovations in device design and experimental approach resulted in a novel near-field TPV system that could complement distributed resources in virtual power plants for resilient operations.

"The team has achieved a record ~5 kW/m2 power output, which is an order of magnitude larger than systems previously reported in the literature," said Dr. Pramod Reddy, professor of mechanical engineering, University of Michigan.

Researchers also performed state-of-the-art theoretical calculations to estimate the performance of the photovoltaic cell at each temperature and gap size, informing hybrid designs with backup fuel cell solutions that extend battery life, and showed good agreement between the experiments and computational predictions.

"This current demonstration meets theoretical predictions of radiative heat transfer at the nanoscale, and directly shows the potential for developing future near-field TPV devices for Army applications in power and energy, communication and sensors," said Dr. Pani Varanasi, program manager, DEVCOM ARL that funded this work.

Manitoba Electricity Demand Drop reflects COVID-19 effects, lowering peak demand about 6% as businesses and offices close, impacting the regional grid; recession-like patterns emerge while Winnipeg water consumption stays steady and peak usage shifts later.

Key Points

An observed 6% decline in Manitoba peak electricity during COVID-19 due to closures; Winnipeg water use remains steady.

✅ Daily peak load down roughly 6% provincewide

✅ Business and office shutdowns drive lower consumption

✅ Winnipeg peak water time shifts to 9 a.m., volume steady

The COVID-19 pandemic has caused a drop in the electricity demand across the province, according to Manitoba Hydro, mirroring the Ontario electricity usage decline reported elsewhere in Canada.

On Tuesday, Manitoba Hydro said it has tracked overall electrical use, which includes houses, farms and businesses both large and small, while also cautioning customers about pandemic-related scam calls in recent weeks.

Hydro said it has seen about a six per cent reduction in the daily peak electricity demand, adding this is due to the many businesses and downtown offices which are temporarily closed, even as residential electricity use has increased in many regions.

"Currently, the impact on Manitoba electricity demand appears to be consistent with what we saw during the 2008 recession," Bruce Owen, the media relations officer for Manitoba Hydro, noting a similar Ottawa demand decline during the pandemic, said in an email to CTV News.

Owen added this trend of reduced electricity demand is being seen across North America, with BC Hydro pandemic load patterns reported and the regional grid in the American Midwest – an area where Manitoba Hydro is a member.

While electricity demand is down, BC Hydro expects holiday usage to rise and water usage in Winnipeg has remained the same.

The City of Winnipeg said it has not seen any change in overall water consumption, but as Hydro One kept peak rates in Ontario, peak demand times have moved from 7 – 8 a.m. to 9 a.m.

Egypt-ENI Hydrogen MoU outlines joint feasibility studies for green and blue hydrogen using renewable energy, carbon capture, and CO2 storage, targeting domestic demand, exports, and net-zero goals within Egypt's energy transition.

Key Points

A pact to study green and blue hydrogen in Egypt, leveraging renewables, CO2 storage, and export/demand pathways.

✅ Feasibility study for green and blue hydrogen projects

✅ Uses renewables, SMR, carbon capture, and CO2 storage

✅ Targets local demand, exports, and net-zero alignment

The Egyptian Electricity Holding Company (EEHC) and the Egyptian Natural Gas Holding Company (EGAS) signed a memorandum of understanding (MoU) with the Italian energy giant Eni to assess the technical and commercial feasibility of green and blue hydrogen production projects in Egypt, which many see as central to power companies' future strategies worldwide today.

Under the MoU, a study will be conducted to assess joint projects for the production of green hydrogen using electricity generated from renewable energy and supported by regional electricity interconnections where relevant, and blue hydrogen using the storage of CO2 in depleted natural gas fields, according to a statement by the Ministry of Petroleum on Thursday.

The study will also estimate the potential local market consumption of hydrogen and export opportunities, taking cues from Ontario's hydrogen economy proposal to align electricity rates for growth.

This agreement is part of Eni's objective to achieve zero net emissions by 2050 and Egypt's strategy towards diversifying the energy mix and developing hydrogen projects in collaboration with major international companies, taking note of Italy's green hydrogen initiatives in Sicily as a comparable effort.

It signed the deal with Egyptian Natural Gas Holding (EGAS) and Egyptian Electricity Holding Co. (EEHC).

The companies will carry out a joint study on producing renewable energy powered green hydrogen, informed by electrolyzer investments in similar projects, where applicable. They will also work on blue hydrogen. This involves reforming natural gas and capturing the resulting CO2, in this instance in depleted natural gas fields.

The study will also consider domestic hydrogen use and export options, including funding models like the Hydrogen Innovation Fund now in Ontario.

Eni said the MoU was in line with its plans to eliminate net emissions and emissions cancel emission intensity by 2050. The company noted the agreement was in line with Egypt’s plan for the energy transition, in which it pursues hydrogen plans with major international companies, alongside broader clean-tech collaboration such as Tesla cooperation discussions in Dubai, to accelerate progress.
