Duke draws $1 billion under its Master Credit Agreement

White Pines Project cancellation highlights Ontario's wind farm contract dispute in Prince Edward County, involving IESO approvals, Progressive Conservatives' legislation, potential court action, and costs to ratepayers amid green energy policy shifts.

Key Points

The termination effort for Ontario's White Pines wind farm contract, triggering legal, legislative, and cost disputes.

✅ Contract with IESO dates to 2009; final approval during election

✅ PCs seek legislation insulating taxpayers from litigation

✅ Cancellation could exceed $100M; cost impact on ratepayers

Cancelling an eastern Ontario green energy project that has been under development for nearly a decade could cost more than $100 million, the president of the company said Wednesday, warning that the dispute could be headed to the courts.

Ontario's governing Progressive Conservatives said this week that one of their first priorities during the legislature's summer sitting would be to cancel the contract for the White Pines Project in Prince Edward County.

Ian MacRae, president of WPD Canada, the company behind the project, said he was stunned by the news given that the project is weeks away from completion.

"What our lawyers are telling us is we have a completely valid contract that we've had since 2009 with the (Independent Electricity System Operator). ... There's no good reason for the government to breach that contract," he said.

The government has also not reached out to discuss the cancellation, he said. Meanwhile, construction on the site is in full swing, he said.

"Over the last couple weeks we've had an average of 100 people on site every day," he said. "The footprint of the project is 100 per cent in. So, all the access roads, the concrete for the base foundations, much of the electrical infrastructure. The sub-station is nearing completion."

The project includes nine wind turbines meant to produce enough electricity to power just over 3,000 homes annually, even as Ontario looks to build on an electricity deal with Quebec for additional supply. All of the turbines are expected to be installed over the next three weeks, with testing scheduled for the following month.

MacRae couldn't say for certain who would have to pay for the cancellation, electricity ratepayers or taxpayers.

"Somehow that money would come from IESO and it would be my assumption that would end up somehow on the ratepayers, despite legislation to lower electricity rates now in place," he said. "We just need to see what the government has in mind and who will foot the bill."

Progressive Conservative house leader Todd Smith, who represents the riding where the project is being built, said the legislation to cancel the project will also insulate taxpayers from domestic litigation over the dismantling of green energy projects.

"This is something that the people of Prince Edward County have been fighting ... for seven years," he said. "This shouldn't have come as a surprise to anybody that this was at the top of the agenda for the incoming government, which has also eyed energy independence in recent decisions."

Smith questioned why Ontario's Independent Electricity System Operator gave the final approval for the project during the spring election campaign.

"There's a lot of questions about how this ever got greenlighted in the first place," he said. "This project was granted its notice to proceed two days into the election campaign ... when (the IESO) should have been in the caretaker mode."

Terry Young, the IESO's vice president of policy, engagement and innovation, said the agency could not comment because of the pending introduction of legislation to cancel the deal, following a recent auditor-regulator dispute that drew attention to oversight.

NDP Leader Andrea Horwath said the new Tory government is behaving like the previous Liberal government by cancelling energy projects and tearing up contracts amid ongoing debates over Ontario's hydro mess and affordability. She likened the Tory plan to the Liberal gas plant scandal that saw the government relocate two plants at a substantial cost to taxpayers.

Covid-19 Energy Transition and Machine Learning reshape climate change policy, electricity planning, and grid operations, from demand forecasting and decarbonization strategies in Europe to scalable electrification modeling and renewable integration across Africa.

Key Points

How the pandemic reshapes energy policy and how ML improves planning, demand forecasts, and grid reliability in Africa.

✅ Pandemic-driven demand shifts strain grid operations and markets

✅ Policy momentum risks rollback; favor future-oriented decarbonization

✅ ML boosts demand prediction, electrification, and grid reliability in Africa

The impact of Covid-19 on the energy system was discussed in an online climate change workshop that also considered how machine learning can help electricity planning in Africa.

This year’s International Conference on Learning Representations event included a workshop held by the Climate Change AI group of academics and artificial intelligence industry representatives, which considered how machine learning can help tackle climate change and highlighted advances by European electricity prediction specialists working in this field.

Bjarne Steffen, senior researcher at the energy politics group at ETH Zürich, shared his insights at the workshop on how Covid-19 and the accompanying economic crisis are affecting recently introduced ‘green’ policies. “The crisis hit at a time when energy policies were experiencing increasing momentum towards climate action, especially in Europe, and in proposals to invest in smarter electricity infrastructure for long-term resilience,” said Steffen, who added the coronavirus pandemic has cast into doubt the implementation of such progressive policies.

The academic said there was a risk of overreacting to the public health crisis, as far as progress towards climate change goals was concerned.

Lobbying

“Many interest groups from carbon-intensive industries are pushing to remove the emissions trading system and other green policies,” said Steffen. “In cases where those policies are having a serious impact on carbon-emitting industries, governments should offer temporary waivers during this temporary crisis, instead of overhauling the regulatory structure.”

However, the ETH Zürich researcher said any temptation to impose environmental conditions to bail-outs for carbon-intensive industries should be resisted. “While it is tempting to push a green agenda in the relief packages, tying short-term environmental conditions to bail-outs is impractical, given the uncertainty in how long this crisis will last,” he said. “It is better to include provisions that will give more control over future decisions to decarbonize industries, such as the government taking equity shares in companies.”

Steffen shared with pv magazine readers an article published in Joule which can be accessed here, and which articulates his arguments about how Covid-19 could affect the energy transition.

Covid-19 in the U.K.

The electricity system in the U.K. is also being affected by Covid-19, even as the U.S. electric grid grapples with climate risks, according to Jack Kelly, founder of London-based, not-for-profit, greenhouse gas emission reduction research laboratory Open Climate Fix.

“The crisis has reduced overall electricity use in the U.K.,” said Kelly. “Residential use has increased but this has not offset reductions in commercial and industrial loads.”

Steve Wallace, a power system manager at British electricity system operator National Grid ESO recently told U.K. broadcaster the BBC electricity demand has fallen 15-20% across the U.K. The National Grid ESO blog has stated the fall-off makes managing grid functions such as voltage regulation more challenging.

Open Climate Fix’s Kelly noted even events such as a nationally-coordinated round of applause for key workers was followed by a dramatic surge in demand, stating: “On April 16, the National Grid saw a nearly 1 GW spike in electricity demand over 10 minutes after everyone finished clapping for healthcare workers and went about the rest of their evenings.”

Climate Change AI workshop panelists also discussed the impact machine learning could have on improving electricity planning in Africa. The Electricity Growth and Use in Developing Economies (e-Guide) initiative funded by fossil fuel philanthropic organization the Rockefeller Foundation aims to use data to improve the planning and operation of electricity systems in developing countries.

E-Guide members Nathan Williams, an assistant professor at the Rochester Institute of Technology (RIT) in New York state, and Simone Fobi, a PhD student at Columbia University in NYC, spoke about their work at the Climate Change AI workshop, which closed on Thursday. Williams emphasized the importance of demand prediction, saying: “Uncertainty around current and future electricity consumption leads to inefficient planning. The weak link for energy planning tools is the poor quality of demand data.”

Fobi said: “We are trying to use machine learning to make use of lower-quality data and still be able to make strong predictions.”

The market maturity of individual solar home systems and PV mini-grids in Africa mean more complex electrification plan modeling is required, similar to integrating AI data centers into Canada's grids at scale.

Modeling

“When we are doing [electricity] access planning, we are trying to figure out where the demand will be and how much demand will exist so we can propose the right technology,” added Fobi. “This makes demand estimation crucial to efficient planning.”

Unlike many traditional modeling approaches, machine learning is scalable and transferable. Rochester’s Williams has been using data from nations such as Kenya, which are more advanced in their electrification efforts, to train machine learning models to make predictions to guide electrification efforts in countries which are not as far down the track.

Williams also discussed work being undertaken by e-Guide members at the Colorado School of Mines, which uses nighttime satellite imagery and machine learning to assess the reliability of grid infrastructure in India, where new algorithms to prevent ransomware-induced blackouts are also advancing.

Rural power

Another e-Guide project, led by Jay Taneja at the University of Massachusetts, Amherst – and co-funded by the Energy and Economic Growth program on development spending based at Berkeley – uses satellite imagery to identify productive uses of electricity in rural areas by detecting pollution signals from diesel irrigation pumps.

Though good quality data is often not readily available for Africa, Williams added, it does exist.

“We have spent years developing trusting relationships with utilities,” said the RIT academic. “Once our partners realize the value proposition we can offer, they are enthusiastic about sharing their data … We can’t do machine learning without high-quality data and this requires that organizations can effectively collect, organize, store and work with data. Data can transform the electricity sector, as shown by Canadian projects to use AI for energy savings, but capacity building is crucial.”

Waste-to-Graphene uses flash joule heating to convert carbon-rich trash into turbostratic graphene for composites, asphalt, concrete, and flexible electronics, delivering scalable, low-cost, high-quality material from food scraps, plastics, and tires with minimal processing.

Key Points

A flash heating method converting waste carbon into turbostratic graphene for scalable, low-cost industrial uses.

✅ Converts food scraps, plastics, and tires into graphene

✅ Produces turbostratic flakes that disperse well in composites

✅ Scalable, low-cost process via flash joule heating

Science doesn’t usually take after fairy tales. But Rumpelstiltskin, the magical imp who spun straw into gold, would be impressed with the latest chemical wizardry. Researchers at Rice University report today in Nature that they can zap virtually any source of solid carbon, from food scraps to old car tires, and turn it into graphene—sheets of carbon atoms prized for applications ranging from high-strength plastic to flexible electronics, and debates over 5G electricity use continue to evolve. Current techniques yield tiny quantities of picture-perfect graphene or up to tons of less prized graphene chunks; the new method already produces grams per day of near-pristine graphene in the lab, and researchers are now scaling it up to kilograms per day.

“This work is pioneering from a scientific and practical standpoint” as it promises to make graphene cheap enough to use to strengthen asphalt or paint, says Ray Baughman, a chemist at the University of Texas, Dallas. “I wish I had thought of it.” The researchers have already founded a new startup company, Universal Matter, to commercialize their waste-to-graphene process, while others are digitizing the electrical system to modernize infrastructure.

With atom-thin sheets of carbon atoms arranged like chicken wire, graphene is stronger than steel, conducts electricity and heat better than copper, and can serve as an impermeable barrier preventing metals from rusting, while advances such as superconducting cables aim to cut grid losses. But since its 2004 discovery, high-quality graphene—either single sheets or just a few stacked layers—has remained expensive to make and purify on an industrial scale. That’s not a problem for making diminutive devices such as high-speed transistors and efficient light-emitting diodes. But current techniques, which make graphene by depositing it from a vapor, are too costly for many high-volume applications. And higher throughput approaches, such as peeling graphene from chunks of the mineral graphite, produce flecks composed of up to 50 graphene layers that are not ideal for most applications.

Graphene comes in many forms. Single sheets, which are ideal for electronics and optics, can be grown using a method called chemical vapor deposition. But it produces only tiny amounts. For large volumes, companies commonly use a technique called liquid exfoliation. They start with chunks of graphite, which is just myriad stacked graphene layers. Then they use acids and solvents, as well as mechanical grinding, to shear off flakes. This approach typically produces tiny platelets each made up of 20 to 50 layers of graphene.

In 2014, James Tour, a chemist at Rice, and his colleagues found they could make a pure form of graphene—each piece just a few layers thick—by zapping a form of amorphous carbon called carbon black with a laser. Brief pulses heated the carbon to more than 3000 kelvins, snapping the bonds between carbon atoms; for comparison, researchers have also generated electricity from falling snow using triboelectric effects. As the cloud of carbon cooled, it coalesced into the most stable structure possible, graphene. But the approach still produced only tiny qualities and required a lot of energy.

Two years ago, Luong Xuan Duy, one of Tour’s graduate students, read that other researchers had created metal nanoparticles by zapping a material with electricity, creating the same brief blast of heat behind the success of the laser graphene approach. “I wondered if I could use that to heat a carbon source and produce graphene,” Duy says. So, he put a dash of carbon black in a clear glass vial and zapped it with 400 volts, similar in spirit to electrical weed zapping approaches in agriculture, for about 200 milliseconds. Initially he got junk. But after a bit of tweaking, he managed to create a bright yellowish white flash, indicating the temperature inside the vial was reaching about 3000 kelvins. Chemical tests revealed he had produced graphene.

It turned out to be a type of graphene that is ideal for bulk uses. As the carbon atoms condense to form graphene, they don’t have time to stack in a regular pattern, as they do in graphite. The result is a material known as turbostatic graphene, with graphene layers jumbled at all angles atop one another. “That’s a good thing,” Duy says. When added to water or other solvents, turbostatic graphene remains suspended instead of clumping up, allowing each fleck of the material to interact with whatever composite it’s added to.

“This will make it a very good material for applications,” says Monica Craciun, a materials physicist at the University of Exeter. In 2018, she and her colleagues reported that adding graphene to concrete more than doubled its compressive strength. Tour’s team saw much the same result. When they added just 0.05% by weight of their flash-produced graphene to concrete, the compressive strength rose 25%; graphene added to polydimethylsiloxane, a common plastic, boosted its strength by 250%.

As digital control spreads across energy networks, research to counter ransomware-driven blackouts is increasingly important for grid resilience.

Those results could reignite efforts to use graphene in a wide range of composites. Researchers in Italy reported recently that adding graphene to asphalt dramatically reduces its tendency to fracture and more than doubles its life span. Last year, Iterchimica, an Italian company, began to test a 250-meter stretch of road in Milan paved with graphene-spiked asphalt. Tests elsewhere have shown that adding graphene to paint dramatically improves corrosion resistance.

These applications would require high-quality graphene by the ton. Fortunately, the starting point for flash graphene could hardly be cheaper or more abundant: Virtually any organic matter, including coffee grounds, food scraps, old tires, and plastic bottles, can be vaporized to make the material. “We’re turning garbage into graphene,” Duy says.

American Green Energy Independence accelerates electrification and renewable energy, leveraging solar, wind, and EVs to boost energy security, cut emissions, create jobs, and reduce reliance on volatile oil and natural gas markets influenced by geopolitics.

Key Points

American Green Energy Independence is a strategy to electrify, expand renewables, and enhance energy security.

✅ Electrifies vehicles, appliances, and infrastructure

✅ Expands solar, wind, and storage to stabilize grids

✅ Cuts oil dependence, strengthens energy security and jobs

As Putin's heavy hand uses Russia's power over oil and natural gas as a weapon against Europe, which is facing an energy nightmare across its markets, and the people of Ukraine, it's impossible not to wonder how we can mitigate the damages he's causing. Simultaneously, it's a devastating reminder of the freedom we so often take for granted and a warning to increase our energy independence as a nation. There are many ways we can, but one of the best is to follow the lead of the European Union and quicken our transition to green and renewable energies.

We've known it for a long time: our reliance on fossil fuels is a national security risk. Volatile prices coupled with our extreme demand mean that concerns over fossil fuel access have driven foreign policy decisions. We've seen it happen countless times — most notably during the wars in Iraq and Afghanistan — and it's played out again in Ukraine, which has leaned on imports to keep the lights on during the crisis. Concerned by Russia's power over the oil and natural gas market, the US and Europe were quite reluctant to impose the harshest, most recent sanctions because doing so will hurt their citizens' pocketbooks.

As homeowners, we know how much decisions like these can hurt, especially with gas prices being historically high even as an energy crisis isn't spurring a green shift for many consumers. However, the solution to this problem isn't to drill more, as some well-funded oil and gas interest groups have claimed. Doing so likely won't even provide a short-term solution to the problem as it takes six months to a year at minimum to build a new well with all its associated infrastructure.

The best long-term solution is to declare our independence from the global oil market amid a global energy war that is driving price hikes and invest in American-made clean energy. We need to electrify our vehicles, appliances, and infrastructure, and make America fully energy independent. This will save families thousands of dollars a year, make our country more self-sufficient, and provide hundreds of thousands of quality jobs here in the Midwest.

Already, over 600,000 Midwesterners are employed in clean-energy professions, and they make 25 percent more than the national median wage. Nationally, clean energy is the biggest job creator in our country's energy sector, employing almost three times as many workers as the fossil fuel industry.

As we employ our own citizens, we will defund Putin's Russia, which has long been funded by his powerful oil and gas industry. Instead of diversifying his economy during the oil boom of the 2010s, Putin doubled down on petroleum. We should exploit his weakness by leading a global movement to abandon the very resource that funds his warmongering. Doing so will further destabilize his economy and protect the citizens of Ukraine, especially as they prepare for winter amid energy challenges today.

We can start doing this as everyday consumers by seeking electric options like stoves, cars, or other appliances. Congress should help Americans afford these changes by providing tax credits for everyday Americans and innovators in electric vehicle and green energy industries. Doing so will spur innovation in the industry, further reducing the cost to consumers. We should also ensure that our semiconductors, solar panels, wind turbines, and other technology needed for a green future are manufactured and assembled in America. This will ensure that our energy industry is safe from price or supply shocks and reduce brownout risks linked to disruptions caused by an international crisis like the invasion of Ukraine.

In many ways, our next steps as a country can define world history for generations to come. Will we continue our reliance on oil and its tacit support of Putin's economy? Or will we intensify our shift to green energies and make our country more self-sufficient and secure? The global spotlight is on us once again to lead. We hope our country will honor the lives of its veterans and the soldiers fighting in Ukraine by strengthening energy security support and transitioning towards green energy.

Ontario Electricity Rate Changes lower OEB Regulated Price Plan costs, adjust Time-of-Use winter hours and tiered thresholds, and modify the Ontario Electricity Rebate, affecting off-peak, mid-peak, and on-peak pricing for households and small businesses.

Key Points

OEB updates lowering RPP prices, shifting TOU hours, adjusting tiers, and modifying the Ontario Electricity Rebate.

✅ Winter TOU: Off-peak 7 p.m.-7 a.m.; weekends, holidays all day.

✅ Tiered pricing adds 400 kWh at lower rate for residential users.

✅ Ontario Electricity Rebate falls to 11.7% from 17% on Nov 1.

Electricity rates are about to change for consumers across Ontario.

On November 1, households and small businesses will see their electricity rates go down under the Ontario Energy Board's (OEB) Regulated Price Plan framework.

Customer's on the OEB's tiered pricing plan will also see their bills lowered on November 1, a shift from the 2021 increase when fixed pricing ended, as winter time-of-use hours and the seasonal change in the killowatt-hour threshold take effect.

Off-peak time-of-use hours will run from 7 p.m. to 7 a.m. during weekdays, including the ultra-low overnight rates option for some customers, and all day on weekends and holidays. On-peak hours will be from 7 a.m. to 11 a.m. and 5 p.m. to 7 p.m. on weekdays, and mid-peak hours from 11 a.m. to 5 p.m. on weekdays.

The winter-tier threshold provides residential customers with an extra 400 kilowatt-hours per month at a lower price during the colder weather, alongside the off-peak price freeze in effect.

The Ontario Electricity Rebate - a pre-tax credit that shows up at the bottom of electricity bills - will also see changes as a hydro rate change takes effect on November 1. Starting next month, the rebate will drop from 17 per cent to 11.7 per cent.

For a typical residential customer, the credit will decrease electricity bills by about $13.91 per month, according to the OEB.

Under the board's winter disconnection ban, electricity providers can't turn off a residential customer's power between November 15, 2022 and April 30, 2023 for failing to pay, and earlier pandemic relief included a fixed COVID-19 hydro rate for customers.

Hydro Quebec transmission expansion aims to move surplus hydroelectric capacity from record reservoirs to the US grid via new interties, increasing exports to New England and New York amid rising winter peak demand.

Key Points

A plan to add capacity and intertie links to export surplus hydro power from Quebec's reservoirs to the US grid.

✅ 245 MW added in 2021; portfolio reaches 37,012 MW

✅ Reservoirs at unprecedented levels; export potential high

✅ Lacks US transmission; working on new interties

Hydro Quebec plans to add an incremental 245 MW of hydro-electric generation capacity in 2021 to its expansive portfolio in the north of the province, while Quebec authorized nearly 1,000 MW for industrial projects across the region, bringing the total capacity to 37,012 MW, an official said Friday

Quebec`s highest peak demand of 39,240 MW occurred on January 22, 2014.

A little over 75% of Quebec`s population heat their homes with electricity, Sutherland said, aligning with Hydro Quebec's strategy to wean the province off fossil fuels over time.

The province-owned company produced 205.1 TWh of power in 2017 and its net exports were 34.4 TWh that year, while Ontario chose not to renew a power deal in a separate development.

Sutherland said Hydro Quebec`s reservoirs are currently at "unprecedented levels" and the company could export more of its electricity to New England and New York, but faces transmission constraints that limit its ability to do so.

Hydro Quebec is working with US transmission developers, electric distribution companies, independent system operators and state government agencies to expand that transmission capacity in order to delivery more power from its hydro system to the US, Sutherland said.

Separately, NB Power signed three deals to bring more Quebec electricity into the province, reflecting growing regional demand.

The last major intertie connection between Quebec and the US was completed close to 30 years ago. The roughly 2,000 MW capacity transmission line that connects into the Boston area was completed in the late 1990s, according to Hydro Quebec spokeswoman Lynn St-Laurent.
