Hydro One called it a severe power "blip," caused by equipment failure.

The sudden, severe drop in power led to a major fire at the Richview Transformer Station in Etobicoke January 30.

The dip, which tripped about 1,500 megawatts of capacity for a fraction of a second, was felt throughout southern Ontario, all the way to the Quebec border and into New York and Michigan, a Hydro One official said.

Lights dimmed, traffic lights stopped working and clock radios started blinking.

The source was traced to a capacitor bank.

A capacitor, about the size of a bread box, regulates voltage, functioning in a fashion similar to a pump that controls water pressure.

There are hundreds of capacitors at the Richview station, and they are inter-connected to form a capacitor bank.

Hydro One doesn't know why the equipment failed.

The capacitor banks were fairly new, maybe four or five years old.

Months of analysis may be needed to find the answer.

What Hydro One knows for sure is that at 6:22 a.m., an operator at the Ontario Grid Control Centre in Barrie switched in a capacitor at the Richview station to increase voltage as people getting a start to their day increased their power usage.

As the capacitor switched in, it somehow failed.

The operator in Barrie received all kinds of alarms.

In the system, however, are breakers much like people have in their homes.

When a fault is sensed, the affected capacitor is immediately taken out of service and power is rerouted.

When that capacitor bank failed, it caused an electricity arc from the power system to the ground. The energy created by that arc blew apart the oil-laden capacitor banks, causing a large explosion and fire, officials said.

Energy Minister Dwight Duncan short-circuited any talk of potential for a major blackout.

"We have the most reliable system in North America. These things do happen," he said of the glitch.

"The system responded appropriately," the energy minister said.

Terry Young, a spokesperson with the Independent Electricity System Operator, which manages Ontario's electricity network, said that demand at the time was normal, noting that on one of the coldest days of the year, power demand was only at 23,100 megawatts.

For comparison, the peak demand last year occurred on Aug. 1 when demand surged to 27,005 megawatts of power.

B.C. residents and businesses get break on electricity bills for three months

BC Hydro COVID-19 Bill Relief offers pandemic support with bill credits, rate cuts, and deferred payments for residential, small business, and industrial customers across B.C., easing utilities costs during COVID-19 economic hardship.

 

Key Points

COVID-19 bill credits, a rate cut, and deferred payments for eligible B.C. homes, small businesses, and industrial customers.

✅ Non-repayable credits equal to 3 months of average bills.

✅ Small businesses closed can skip bills for three months.

✅ Large industry may defer 50% of electricity costs.

 

B.C. residents who have lost their jobs or had their wages cut will get a three-month break on BC Hydro bills, while small businesses, amid commercial consumption plummets during COVID-19, are also eligible to apply for similar relief.

Premier John Horgan said Wednesday the credit for residential customers will be three times a household’s average monthly bill over the past year and does not have to be repaid as part of the government’s support package during the COVID-19 pandemic, as BC Hydro demand down 10% highlights the wider market pressures.

He said small businesses that are closed will not have to pay their power bills for three months, and in Ontario an Ontario COVID-19 hydro rebate complemented similar relief, and large industrial customers, including those operating mines and pulp mills, can opt to have 50 per cent of their electricity costs deferred, though a deferred costs report warned of long-term liabilities.

BC Hydro rates will be cut for all customers by one per cent as of April 1, a move similar to Ontario 2021 rate reductions that manufacturers supported lower rates at the time, after the B.C. Utilities Commission provided interim approval of an application the utility submitted last August.

Eligible residential customers can apply for bill relief starting next week and small business applications will be accepted as of April 14, while staying alert to BC Hydro scam attempts during this period, with the deadline for both categories set at June 30.

No deal Brexit could trigger electricity shock for Northern Ireland

Northern Ireland No-Deal Power Contingency outlines Whitehall plans to deploy thousands of generators on barges in the Irish Sea, safeguard the electricity market, and avert blackouts if Brexit disrupts imports from the Republic of Ireland.

 

Key Points

A UK Whitehall plan to prevent NI blackouts by deploying generators and protecting cross-border electricity flows.

✅ Barges in Irish Sea to host temporary power generators

✅ Mitigates loss of EU market access in a no-deal Brexit

✅ Ensures NI supply if Republic cuts electricity exports

 

Such a scenario could see thousands of electricity generators being requisitioned at short notice and positioned on barges in the Irish Sea, even as Great Britain's generation mix shapes wider supply dynamics, to help keep the region going, a Whitehall document quoted by the Financial Times states.

An emergency operation could see equipment being brought back from places like Afghanistan, where the UK still has a military presence, the newspaper said.

The extreme situation could arise because Northern Ireland shares a single energy market with the Irish Republic, where Irish grid price spikes have heightened concern about stability.

The region relies on energy imports from the Republic because it does not have enough generating capacity itself, and the UK is aiming to negotiate a deal to allow that single electricity market on the island of Ireland to continue post-EU withdrawal, while virtual power plant proposals for UK homes are explored to avoid outages, the FT stated.

However, if no Brexit deal is agreed Whitehall fears suppliers in the Irish Republic could cut off power because the UK would no longer be part of the European electricity market, and a recent short supply warning from National Grid underscores the risk.

In a bid to prevent blackouts in Northern Ireland in a worse case situation the Government would need to put thousands of generators into place, even as an emergency energy plan has reportedly not gone ahead nationwide, according to the report.

And officials fear they may need to commandeer some generators from the military in such a scenario, the FT reports.

An official was quoted by the newspaper as saying the preparations were “gob-smacking”.

Electricity Regulation With Equity & Justice For All

Energy equity in utility regulation prioritizes fair rates, clean energy access, and DERs, addressing fixed charges and energy burdens on low-income households through stakeholder engagement and public utility commission reforms.

 

Key Points

Fairly allocates clean energy benefits and rate burdens, ensuring access and protections for low-income households.

✅ Reduces fixed charges that burden low-income households

✅ Funds community participation in utility proceedings

✅ Prioritizes DERs, energy efficiency, and solar in impacted areas

 

By Kiran Julin

Pouring over the line items on your monthly electricity bill may not sound like an enticing way to spend an afternoon, but the way electricity bills are structured has a significant impact on equitable energy access and distribution. For example, fixed fees can have a disproportionate impact on low-income households. And combined with other factors, low-income households and households of color are far more likely to report losing home heating service, with evidence from pandemic power shut-offs highlighting these disparities, according to recent federal data.

Advancing Equity in Utility Regulation, a new report published by the U.S. Department of Energy’s (DOE’s) Lawrence Berkeley National Laboratory (Berkeley Lab), makes a unifying case that utilities, regulators, and stakeholders need to prioritize energy equity in the deployment of clean energy technologies and resources, aligning with a people-and-planet electricity future envisioned by advocacy groups. Equity in this context is the fair distribution of the benefits and burdens of energy production and consumption. The report outlines systemic changes needed to advance equity in electric utility regulation by providing perspectives from four organizations — Portland General Electric, a utility company; the National Consumer Law Center, a consumer advocacy organization; and the Partnership for Southern Equity and the Center for Biological Diversity, social justice and environmental organizations.
 
“While government and ratepayer-funded energy efficiency programs have made strides towards equity by enabling low-income households to access energy-efficiency measures, that has not yet extended in a major way to other clean-energy technologies,” said Lisa Schwartz, a manager and strategic advisor at Berkeley Lab and technical editor of the report. “States and utilities can take the lead to make sure the clean-energy transition does not leave behind low-income households and communities of color. Decarbonization and energy equity goals are not mutually exclusive, and in fact, they need to go hand-in-hand.”

Energy bills and electricity rates are governed by state laws and utility regulators, whose mission is to ensure that utility services are reliable, safe, and fairly priced. Public utility commissions also are increasingly recognizing equity as an important goal, tool, and metric, and some customers face major changes to electric bills as reforms advance. While states can use existing authorities to advance equity in their decision-making, several, including Illinois, Maine, Oregon, and Washington, have enacted legislation over the last couple of years to more explicitly require utility regulators to consider equity.

“The infrastructure investments that utility companies make today, and regulator decisions about what goes into electricity bills, including new rate design steps that shape customer costs, will have significant impacts for decades to come,” Schwartz said.

Solutions recommended in the report include considering energy justice goals when determining the “public interest” in regulatory decisions, allocating funding for energy justice organizations to participate in utility proceedings, supporting utility programs that increase deployment of energy efficiency and solar for low-income households, and accounting for energy inequities and access in designing electricity rates, while examining future utility revenue models as technologies evolve.

The report is part of the Future of Electric Utility Regulation series that started in 2015, led by Berkeley Lab and funded by DOE, to encourage informed discussion and debate on utility trends and tackling the toughest issues related to state electric utility regulation. An advisory group of utilities, public utility commissioners, consumer advocates, environmental and social justice organizations, and other experts provides guidance.

 

Taking stock of past and current energy inequities

One focus of the report is electricity bills. In addition to charges based on usage, electricity bills usually also have a fixed basic customer charge, which is the minimum amount a household has to pay every month to access electricity. The fixed charge varies widely, from $5 to more than $20. In recent years, utility companies have sought sizable increases in this charge to cover more costs, amid rising electricity prices in some markets.

This fixed charge means that no matter what a household does to use energy more efficiently or to conserve energy, there is always a minimum cost. Moreover, low-income households often live in older, poorly insulated housing. Current levels of public and utility funding for energy-efficiency programs fall far short of the need. The combined result is that the energy burden – or percent of income needed to keep the lights on and their homes at a healthy temperature – is far greater for lower-income households.

“While all households require basic lighting, heating, cooling, and refrigeration, low-income households must devote a greater proportion of income to maintain basic service,” explained John Howat and Jenifer Bosco from the National Consumer Law Center and co-authors of Berkeley Lab’s report. Their analysis of data from the most recent U.S. Energy Information Administration’s Residential Energy Consumption Survey shows households with income less than $20,000 reported losing home heating service at a pace more than five times higher than households with income over $80,000. Households of color were far more likely than those with a white householder to report loss of heating service. In addition, low-income households and households of color are more likely to have to choose between paying their energy bill or paying for other necessities, such as healthcare or food.

Based on the most recent data (2015) from the U.S. Energy Information Administration (EIA), households with income less than $20,000 reported losing home heating service at a rate more than five times higher than households with income over $80,000. Households of color were far more likely than those with a white householder to report loss of heating service. Click on chart for larger view.

Moreover, while many of the infrastructure investment decisions that utilities make, such as whether and where to build a new power plant, often have long-term environmental and health consequences, impacted communities often are not at the table. “Despite bearing an inequitable proportion of the negative impacts of environmental injustices related to fossil fuel-based energy production and climate change, marginalized communities remain virtually unrepresented in the energy planning and decision-making processes that drive energy production, distribution, and regulation,” wrote Chandra Farley, CEO of ReSolve and a co-author of the report.


Engaging impacted communities
Each of the perspectives in the report identify a need for meaningful engagement of underrepresented and disadvantaged communities in energy planning and utility decision-making. “Connecting the dots between energy, racial injustice, economic disinvestment, health disparities, and other associated equity challenges becomes a clarion call for communities that are being completely left out of the clean energy economy,” wrote Farley, who previously served as the Just Energy Director at Partnership for Southern Equity. “We must prioritize the voices and lived experiences of residents if we are to have more equity in utility regulation and equitably transform the energy sector.”

In another essay in the report, Nidhi Thaker and Jake Wise from Portland General Electric identify the importance of collaborating directly with the communities they serve. In 2021, the Oregon Legislature passed Oregon HB 2475, which allows the Oregon Public Utility Commission to allocate ratepayer funding for organizations representing people most affected by a high energy burden, enabling them to participate in utility regulatory processes.

The report explains why energy equity requires correcting inequities resulting from past and present failures as well as rethinking how we achieve future energy and decarbonization goals. “Equity in energy requires adopting an expansive definition of the ‘public interest’ that encompasses energy, climate, and environmental justice. Energy equity also means prioritizing the deployment of distributed energy resources and clean energy technologies in areas that have been hit first and worst by the existing fossil fuel economy,” wrote Jean Su, energy justice director and senior attorney at the Center for Biological Diversity.

This report was supported by DOE’s Grid Modernization Laboratory Consortium, with funding from the Office of Energy Efficiency and Renewable Energy and the Office of Electricity.

Ontario will refurbish Pickering B NGS

Pickering nuclear refurbishment will modernize Ontario's Candu reactors at Pickering B, sustaining 2,000 MW of clean electricity, aiding net-zero goals, and aligning with Ontario Power Generation plans and Canadian Nuclear Safety Commission reviews.

 

Key Points

An 11-year overhaul of Pickering B Candu reactors to extend life, keep 2,000 MW online, and back Ontario net-zero grid.

✅ 11-year project; 11,000 annual jobs; $19.4B GDP impact.

✅ Refurbishes four Pickering B Candu units; maintains 2,000 MW.

✅ Requires Canadian Nuclear Safety Commission license approvals.

 

The Ontario government has announced its intention to pursue a Pickering refurbishment at the venerable nuclear power station, which has been operational for over fifty years. This move could extend the facility's life by another 30 years.

This decision is timely, as Ontario anticipates a significant surge in electricity demand and a growing electricity supply gap in the forthcoming years. Additionally, all provinces are grappling with new federal mandates for clean electricity, necessitating future power plants to achieve net-zero carbon emissions.

Todd Smith, the Energy Minister, is expected to endorse Ontario Power Generation's proposal for the plant's overhaul, as per a preliminary version of a government press release.

The renovation will focus on four Candu reactors, known collectively as Pickering B, which were originally commissioned in the early 1980s. This upgrade is projected to continue delivering 2,000 megawatts of power, equivalent to the current output of these units.

According to the press release, the project will span 11 years, create approximately 11,000 annual jobs, and contribute $19.4 billion to Ontario's GDP. However, the total budget for the project remains unspecified.

The project follows the ongoing refurbishment of four units at the nearby Darlington nuclear station, which is more than halfway completed with a budget of $12.8 billion.

The proposal awaits the Canadian Nuclear Safety Commission's approval, and officials face extension request timing considerations before key deadlines.

The Commission is also reviewing a prior request from OPG to extend the operational license of the existing Pickering B units until 2026. This extension would allow the plant to safely continue operating until the commencement of its renovation, pending approval.

 

Ontario's Ambitious Nuclear Strategy

The announcement regarding Pickering is part of Ontario's broader clean energy plan for an unprecedented expansion of nuclear power in Canada.

Last summer, the province announced its intention to nearly double the output at Bruce Power, currently the world's largest nuclear generating station.

Additionally, Ontario revealed SMR plans to construct three more alongside the existing project at Darlington. These reactors are expected to supply enough electricity to power around 1.2 million homes.

Discussions about revitalizing the Pickering facility began in 2022, after the station had been slated to close as planned amid debate, with Ontario Power Generation submitting a feasibility report to the government last summer.

The Ford government emphasized the necessity of this nuclear expansion to meet the increasing electricity demands anticipated from the auto sector's shift to electric vehicles, the steel industry's move away from coal-fired furnaces, and the growing population in Ontario.

Ontario's capability to attract major international car manufacturers like Volkswagen and Stellantis to produce electric vehicles and batteries is partly attributed to the fact that 90% of the province's electricity comes from non-fossil fuel sources.

WEC Energy Group to buy 80% stake in Illinois wind farm for $345 million

WEC Energy Blooming Grove Investment underscores Midwest renewable energy growth, with Invenergy, GE turbines, and 250 MW wind power capacity, tax credits, PPAs, and utility-scale generation supplying corporate offtakers via long-term contracts.

 

Key Points

It is WEC Energy's $345M purchase of an 80% stake in Invenergy's 250 MW Blooming Grove wind farm in Illinois.

✅ 94 GE turbines; 250 MW utility-scale wind capacity

✅ Output contracted to two multinational offtakers

✅ Eligible for 100% bonus depreciation and wind tax credits

 

WEC Energy Group, the parent company of We Energies, is buying an 80% stake in a wind farm, as seen with projects like Enel's 450 MW wind farm coming online, in McLean County, Illinois, for $345 million.

The wind farm, known as the Blooming Grove Wind Farm, is being developed by Invenergy, which recently completed the largest North American wind build with GE partners, a company based in Chicago that develops wind, solar and other power projects. WEC Energy has invested in several wind farms developed by Invenergy.

With the agreement announced Monday, WEC Energy will have invested more than $1.2 billion in wind farms in the Midwest, echoing heartland investment growth across the region. The power from the wind farms is sold to other utilities or companies, as federal initiatives like DOE wind awards continue to support innovation, and the projects are separate from the investments made by WEC Energy's regulated utilities, such as We Energies, in wind power.

The project, which will consist of 94 wind turbines from General Electric, is expected to be completed this year, similar to recent project operations in the sector, and will have a capacity of 250 megawatts, WEC said in a news release.

Affiliates of two undisclosed multinational companies akin to EDF's offshore investment activity have contracted to take all of the wind farm's output.

The investment is expected to be eligible for 100% bonus depreciation and, as wind economics help illustrate key trends, the tax credits available for wind projects, WEC Energy said.

Hungary's Quiet Alliance with Russia in Europe's Energy Landscape

Hungary's Russian Energy Dependence underscores EU tensions, as TurkStream gas flows, discounted imports, and pipeline reliance challenge sanctions, energy security, diversification, and decoupling goals amid Ukraine war pressures and bloc unity concerns.

 

Key Points

It is Hungary's reliance on Russian gas and oil via TurkStream, complicating EU sanctions and energy independence.

✅ 85% gas, 60% oil imports from Russia via TurkStream pipelines.

✅ Discounted contracts seldom cut bills; security cited by Budapest.

✅ EU decoupling targets hampered; sanctions leverage and unity erode.

 

Hungary's energy policies have positioned it as a notable outlier within the European Union, particularly in the context of the ongoing geopolitical tensions stemming from Russia's invasion of Ukraine. While the EU has been actively working to reduce its dependence on Russian energy sources through an EU $300 billion plan to dump Russian energy, Hungary has maintained and even strengthened its energy ties with Moscow, raising concerns about EU unity and the effectiveness of sanctions.

Strategic Energy Dependence

Hungary's energy infrastructure is heavily reliant on Russian supplies. Approximately 85% of Hungary's natural gas and more than 60% of its oil imports originate from Russia. This dependence is facilitated through pipelines such as TurkStream, which delivers Russian gas to Hungary via Turkey and the Balkans amid Europe's energy nightmare over price volatility and security. In 2025, Hungary's gas imports through TurkStream are projected to reach 8 billion cubic meters, a significant increase from previous years. These imports are often secured at discounted rates, although such savings may not always be passed on to Hungarian consumers.

Political and Economic Considerations

Prime Minister Viktor Orbán has been a vocal critic of EU sanctions against Russia and has consistently blocked EU initiatives aimed at providing military aid to Ukraine, even as Ukraine leans on power imports to keep the lights on. His government argues that Russia's military capabilities make it an unyielding adversary and that a ceasefire would only solidify its territorial gains. Orbán's stance has led to Hungary's isolation within the EU on matters related to the conflict in Ukraine.

Economically, Hungary's reliance on Russian energy has been justified by the government as a means to maintain low energy prices for consumers and ensure energy security. However, critics argue that this strategy undermines EU efforts to achieve energy independence and reduces the bloc's leverage over Russia amid a global energy war marked by price hikes and instability.

EU's Response and Challenges

The European Union has set ambitious goals to reduce its reliance on Russian energy, aiming to halt imports of Russian natural gas by the end of 2027 and prohibit new contracts starting in 2025 while exploring gas price cap strategies to contain market volatility. However, Hungary's continued imports of Russian energy complicate these efforts. The TurkStream pipeline, in particular, has become a focal point in discussions about the EU's energy strategy, as it enables ongoing Russian gas exports to Europe despite the bloc's broader decoupling initiatives.

Hungary's actions have raised concerns among other EU member states about the effectiveness of the sanctions regime and the potential for other countries to exploit similar loopholes. There are calls for stricter policies, including banning spot gas purchases and enforcing traceability of gas origins, and consideration of emergency measures to limit electricity prices to ensure genuine energy independence and reduce overreliance on external suppliers.

Hungary's steadfast energy relationship with Russia presents a significant challenge to the European Union's collective efforts to reduce dependence on Russian energy sources. While Hungary argues that its energy strategy is in the national interest, it risks undermining EU solidarity and the bloc's broader geopolitical objectives. As the EU continues to navigate its energy transition and response to the ongoing conflict in Ukraine, including energy ceasefire violations reported by both sides, Hungary's position will remain a critical point of contention within the union.
