A broken insulator at the Bedeque substation shut down one of the two cables that carries electricity to PEI from the mainland, leaving thousands without electricity.

The problem started at 6 p.m. and took about 3.5 hours for Maritime Electric to repair. At one point 23,000 households were without electricity.

While Maritime Electric has oil-fired generators on the Island, it is heavily reliant on the far less expensive power it can import via two cables under the Northumberland Strait. Those cables are close to capacity, and when one goes down, the electricity grid goes into a partial shutdown to protect the remaining cable.

"One of the things that can damage that type of equipment is overloading it," said Maritime Electric vice-president of corporate planning and energy supply John Gaudet.

"We want to make sure that we take care of them the best we can."

Maritime Electric was able to provide 30 MW of power from the Eastern Kings Wind Farm, saving it from firing up more generators.

"It just was good fortune that the wind was blowing," said Gaudet.

"It was a classic example of wind replacing oil."

The cables to the mainland were installed in 1977. At the time, either one could supply the entire province's needs, but that is no longer the case.

The province has been lobbying the federal government for funding for a new cable to the mainland, in part to export wind power produced on the Island.

Maritime Electric is continuing to investigate why the insulator at the Bedeque substation failed.

How Canada can capitalize on U.S. auto sector's abrupt pivot to electric vehicles

Canadian EV Manufacturing is accelerating with GM, Ford, and Project Arrow, integrating cross-border supply chains, battery production, rare-earths like lithium and cobalt, autonomous tech, and home charging to drive clean mobility and decarbonization.

 

Key Points

Canadian EV manufacturing spans electric and autonomous vehicles, domestic batteries, and integrated US-Canada trade.

✅ GM and Ford retool plants for EVs and autonomous production

✅ Project Arrow showcases Canadian zero-emission supply capabilities

✅ Lithium, cobalt, and battery hubs target cross-border resilience

 

The storied North American automotive industry, the ultimate showcase of Canada’s high-tensile trade ties with the United States and emerging Canada-U.S. collaboration on EVs momentum, is about to navigate a dramatic hairpin turn.

But as the Big Three veer into the all-electric, autonomous era, some Canadians want to seize the moment and take the wheel.

“There’s a long shadow between the promise and the execution, but all the pieces are there,” says Flavio Volpe, president of the Automotive Parts Manufacturers’ Association.

“We went from a marriage on the rocks to one that both partners are committed to. It could be the best second chapter ever.”

Volpe is referring specifically to GM, which announced late last month an ambitious plan to convert its entire portfolio of vehicles to an all-electric platform by 2035.

But that decision is just part of a cascading transformation across the industry, marking an EV inflection point with existential ramifications for one of the most tightly integrated cross-border manufacturing and supply-chain relationships in the world.

China is already working hard to become the “source of a new way” to power vehicles, President Joe Biden warned last week.

“We just have to step up.”

Canada has both the resources and expertise to do the same, says Volpe, whose ambitious Project Arrow concept — a homegrown zero-emissions vehicle named for the 1950s-era Avro interceptor jet — is designed to showcase exactly that, as recent EV assembly deals in Canada underscore.

“We’re going to prove to the market, we’re going to prove to the (manufacturers) around the planet, that everything that goes into your zero-emission vehicle can be made or sourced here in Canada,” he says.

“If somebody wants to bring what we did over the line and make 100,000 of them a year, I’ll hand it to them.”

GM earned the ire of Canadian auto workers in 2018 by announcing the closure of its assembly plant in Oshawa, Ont. It later resurrected the facility with a $170-million investment to retool it for autonomous vehicles.

“It was, ‘You closed Oshawa, how dare you?’ And I was one of the ‘How dare you’ people,” Volpe says.

“Well, now that they’ve reopened Oshawa, you sit there and you open your eyes to the commitment that General Motors made.”

Ford, too, has entered the fray, promising $1.8 billion to retool its sprawling landmark facility in Oakville, Ont., to build EVs.

It’s a leap of faith of sorts, considering what market experts say is ongoing consumer doubt about EVs and EV supply shortages that drive wait times.

“Range anxiety” — the persistent fear of a depleted battery at the side of the road — remains a major concern, even though it’s less of a problem than most people think.

Consulting firm Deloitte Canada, which has been tracking automotive consumer trends for more than a decade, found three-quarters of future EV buyers it surveyed planned to charge their vehicles at home overnight.

“The difference between what is a perceived issue in a consumer’s mind and what is an actual issue is actually quite negligible,” Ryan Robinson, Deloitte’s automotive research leader, says in an interview.

“It’s still an issue, full stop, and that’s something that the industry is going to have to contend with.”

So, too, is price, especially with the end of the COVID-19 pandemic still a long way off. Deloitte’s latest survey, released last month, found 45 per cent of future buyers in Canada hope to spend less than $35,000 — a tall order when most base electric-vehicle models hover between $40,000 and $45,000.

“You put all of that together and there’s still, despite the electric-car revolution hype, some major challenges that a lot of stakeholders that touch the automotive industry face,” Robinson says.

“It’s not just government, it’s not just automakers, but there are a variety of stakeholders that have a role to play in making sure that Canadians are ready to make the transition over to electric mobility.”

With protectionism no longer a dirty word in the United States and Biden promising to prioritize American workers and suppliers, the Canadian government’s job remains the same as it ever was: making sure the U.S. understands Canada’s mission-critical role in its own economic priorities.

“We’re both going to be better off on both sides of the border, as we have been in the past, if we orient ourselves toward this global competition as one force,” says Gerald Butts, vice-chairman of the political-risk consultancy Eurasia Group and a former principal secretary to Prime Minister Justin Trudeau.

“It served us extraordinarily well in the past … and I have no reason to believe it won’t serve us well in the future.”

Last month, GM announced a billion-dollar plan to build its new all-electric BrightDrop EV600 van in Ingersoll, Ont., at Canada’s first large-scale EV manufacturing plant for delivery vehicles.

That investment, Volpe says, assumes Canada will take the steps necessary to help build a homegrown battery industry — with projects such as a new Niagara-region battery plant pointing the way — drawing on the country’s rare-earth resources like lithium and cobalt that are waiting to be extracted in northern Ontario, Quebec and elsewhere.

Given that the EV industry is still in his infancy, the free market alone won’t be enough to ensure those resources can be extracted and developed, he says.

“General Motors made a billion-dollar bet on Canada because it’s going to assume that the Canadian government — this one or the next one — is going to commit” to building that business.

Such an investment would pay dividends well beyond the auto sector, considering the federal Liberal government’s commitment to lowering greenhouse gas-emissions, including a 2035 EV mandate, and meeting targets set out in the Paris climate accord.

“If you make investments in renewable energy and utility storage using battery technology, you can build an industry at scale that the auto industry can borrow,” Volpe says.

Major manufacturing, retail and office facilities would be able to use that technology to help “shave the peak” off Canada’s GHG emissions and achieve those targets, all the while paving the way for a self-sufficient electric-vehicle industry.

“You’d be investing in the exact same technology you’d use in a car.”

There’s one problem, says Robinson: the lithium-ion batteries on roads right now might not be where the industry ultimately lands.

“We’re not done with with battery technology,” Robinson says. “What you don’t want to do is invest in a technology that is that is rapidly evolving, and could potentially become obsolete going forward.”

Fuel cells — energy-efficient, hydrogen-powered units that work like batteries, but without the need for constant recharging — continue to be part of the conversation, he adds.

“The amount of investment is huge, and you want to be sure that you’re making the right decision, so you don’t find yourself behind the curve just as all that capacity is coming online.”

German official says nuclear would do little to solve gas issue

Germany Nuclear Phase-Out drives policy amid gas supply risks, Nord Stream 1 shutdown fears, Russia dependency, and energy security planning, as Robert Habeck rejects extending reactors, favoring coal backup, storage, and EU diversification strategies.

 

Key Points

Ending Germany's last reactors by year end despite gas risks, prioritizing storage, coal backup, and EU diversification.

✅ Reactors' legal certification expires at year end

✅ Minimal gas savings from extending nuclear capacity

✅ Nord Stream 1 cuts amplify energy security risks

 

Germany’s vice-chancellor has defended the government’s commitment to ending the use of nuclear power at the end of this year, amid fears that Russia may halt natural gas supplies entirely.

Vice-Chancellor Robert Habeck, who is also the economy and climate minister and is responsible for energy, argued that keeping the few remaining reactors running would do little to address the problems caused by a possible natural gas shortfall.

“Nuclear power doesn’t help us there at all,” Habeck, said at a news conference in Vienna on Tuesday. “We have a heating problem or an industry problem, but not an electricity problem – at least not generally throughout the country.”

The main gas pipeline from Russia to Germany shut down for annual maintenance on Monday, as Berlin grew concerned that Moscow may not resume the flow of gas as scheduled.

The Nord Stream 1 pipeline, Germany’s main source of Russian gas, is scheduled to be out of action until July 21 for routine work that the operator says includes “testing of mechanical elements and automation systems”.

But German officials are suspicious of Russia’s intentions, particularly after Russia’s Gazprom last month reduced the gas flow through Nord Stream 1 by 60 percent.

Gazprom cited technical problems involving a gas turbine powering a compressor station that partner Siemens Energy sent to Canada for overhaul.

Germany’s main opposition party has called repeatedly to extend nuclear power by keeping the country’s last three nuclear reactors online after the end of December. There is some sympathy for that position in the ranks of the pro-business Free Democrats, the smallest party in Chancellor Olaf Scholz’s governing coalition.

In this year’s first quarter, nuclear energy accounted for 6 percent of Germany’s electricity generation and natural gas for 13 percent, both significantly lower than a year earlier. Germany has been getting about 35 percent of its gas from Russia.

Habeck said the legal certification for the remaining reactors expires at the end of the year and they would have to be treated thereafter as effectively new nuclear plants, complete with safety considerations and the likely “very small advantage” in terms of saving gas would not outweigh the complications.

Fuel for the reactors also would have to be procured and Scholz has said that the fuel rods are generally imported from Russia.

Opposition politicians have argued that Habeck’s environmentalist Green party, which has long strongly supported the nuclear phase-out, is opposing keeping reactors online for ideological reasons, even as some float a U-turn on the nuclear phaseout in response to the energy crisis.

Reducing dependency on Russia
Germany and the rest of Europe are scrambling to fill the gas storage in time for the northern hemisphere winter, even as Europe is losing nuclear power at a critical moment and reduce their dependence on Russian energy imports.

Prior to the Russian invasion of Ukraine, Berlin had said it considered nuclear energy dangerous and in January objected to European Union proposals that would let the technology remain part of the bloc’s plans for a climate-friendly future that includes a nuclear option for climate change pathway.

“We consider nuclear technology to be dangerous,” government spokesman Steffen Hebestreit told reporters in Berlin, noting that the question of what to do with radioactive waste that will last for thousands of generations remains unresolved.

While neighbouring France aimed to modernise existing reactors, Germany stayed on course to switch off its remaining three nuclear power plants at the end of this year and phase out coal by 2030.

Last month, Germany’s economy minister said the country would limit the use of natural gas for electricity production and make a temporary recourse to coal generation to conserve gas.

“It’s bitter but indispensable for reducing gas consumption,” Robert Habeck said.

Tesla Expands Charging Network in NYC

Tesla NYC Supercharger Expansion adds rapid EV charging across Manhattan, Brooklyn, and Queens, strengthening infrastructure, easing range anxiety, and advancing New York City sustainability goals with fast chargers at strategic commercial and residential-adjacent locations.

 

Key Points

Tesla's plan to add rapid EV charging across NYC, boosting access, easing range anxiety, and advancing climate targets.

✅ New Superchargers in Manhattan, Brooklyn, and Queens

✅ Faster charging to cut downtime and range anxiety

✅ Partnerships with businesses to expand public access

 

In a significant move to enhance the EV charging infrastructure across the city, Tesla has announced plans to expand its network of charging stations throughout New York City. This investment is set to bolster the availability of charging options, making it more convenient for EV owners while encouraging more residents to consider electric vehicles as a viable alternative to traditional gasoline-powered cars.

The Growing Need for Charging Infrastructure

As the demand for electric vehicles continues to rise amid the American EV boom across the country, the need for a robust charging infrastructure has become increasingly critical. With New York City setting ambitious goals to reduce greenhouse gas emissions, the expansion of EVs is seen as a crucial component of its sustainability strategy. Currently, the city aims to have 50% of all vehicles electrified by 2030, a target that necessitates a significant increase in charging stations.

Tesla’s initiative to install more charging points in NYC aligns perfectly with these goals and reflects how charging networks are competing nationwide to expand access, drawing more drivers to consider electric vehicles. By enhancing the charging network, Tesla is not only catering to its existing customers but also appealing to potential EV buyers who may have previously hesitated due to range anxiety or limited charging options.

A Look at the Expansion Plans

The details of Tesla's expansion include adding several new Supercharger stations across key locations in Manhattan, Brooklyn, and Queens, as US automakers move to build 30,000 public chargers nationwide to boost coverage. These stations will be strategically placed to ensure maximum accessibility, especially in densely populated areas where residents may not have easy access to home charging.

Tesla’s Superchargers are known for their rapid charging capabilities, allowing EV drivers to recharge their vehicles in a fraction of the time it would take at a standard charging station. This efficiency will be particularly beneficial in a bustling urban environment like NYC, where convenience and time are of the essence.

Moreover, Tesla is also exploring partnerships with local businesses and property owners to install charging stations at commercial locations. This initiative would not only create more charging opportunities but also encourage businesses to attract EV-driving customers, further promoting electric vehicle adoption.

Impact on EV Adoption in NYC

The expansion of Tesla's charging network is expected to have a positive ripple effect on the adoption of electric vehicles in New York City. With more charging stations available, potential buyers will feel more confident in making the switch to electric. The convenience of accessible charging can significantly reduce range anxiety, a common concern among potential EV buyers.

Additionally, this expansion will likely encourage other automakers to invest in charging infrastructure, as utilities pursue a bullish course on charging to support deployment, leading to a more interconnected network of charging options across the city. As more drivers embrace electric vehicles, the demand for charging will continue to grow, a trend that will test state power grids in the coming years, further solidifying the need for a comprehensive and reliable infrastructure.

Supporting Sustainable Initiatives

Tesla's investment in NYC's charging infrastructure is also part of a broader commitment to sustainability. As cities grapple with the challenges of climate change and air pollution, transitioning to electric vehicles is seen as a vital strategy for reducing emissions. Electric vehicles produce zero tailpipe emissions, which contributes to cleaner air and a healthier urban environment.

Moreover, with the increasing push towards renewable energy sources, the integration of electric vehicles into the city’s transportation system can help reduce reliance on fossil fuels, with energy storage and mobile charging adding flexibility to support the grid. As more charging stations utilize renewable energy, the overall carbon footprint of electric vehicles will continue to decrease, aligning with New York City's climate goals.

Looking Ahead

As Tesla moves forward with its expansion plans in New York City, the implications for both the automotive industry and urban sustainability are profound. By enhancing the charging infrastructure, Tesla is not only facilitating the growth of electric vehicles but also playing a crucial role in the city’s efforts to combat climate change.

More pylons needed to ensure 'lights stay on' in Scotland, says renewables body

Scottish Renewable Grid Upgrades address outdated infrastructure, expanding transmission lines, pylons, and substations to move clean energy, meet rising electricity demand, and integrate onshore wind, offshore wind, and battery storage across Scotland.

 

Key Points

Planned transmission upgrades in Scotland to move clean power via new lines and substations for a low-carbon grid.

✅ Fivefold expansion of transmission lines by 2030

✅ Enables onshore and offshore wind integration

✅ New pylons, substations, and routes face local opposition

 

Renewable energy in Scotland is being held back by outdated grid infrastructure, industry leaders said, with projects stuck on hold underscoring their warning that new pylons and power lines are needed to "ensure our lights stay on".

Scottish Renewables said new infrastructure is required to transmit the electricity generated by green power sources and help develop "a clean energy future" informed by a broader green recovery agenda.

A new report from the organisation - which represents companies working across the renewables sector - makes the case for electricity infrastructure to be updated, aligning with global network priorities identified elsewhere.

But it comes as electricity firms looking to build new lines or pylons face protests, with groups such as the Strathpeffer and Contin Better Cable Route challenging power giant SSEN over the route chosen for a network of pylons that will run for about 100 miles from Spittal in Caithness to Beauly, near Inverness.

Scottish Renewables said it is "time to be upfront and honest" about the need for updated infrastructure.

It said previous work by the UK National Grid estimated "five times more transmission lines need to be built by 2030 than have been built in the past 30 years, at a cost of more than £50bn".

The Scottish Renewables report said: "Scotland is the UK's renewable energy powerhouse. Our winds, tides, rainfall and longer daylight hours already provide tens of thousands of jobs and billions of pounds of economic activity.

"But we're being held back from doing more by an electricity grid designed for fossil fuels almost a century ago, a challenge also seen in the Pacific Northwest today."

Investment in the UK transmission network has "remained flat, and even decreased since 2017", echoing stalled grid spending trends elsewhere, the report said.

It added: "We must build more power lines, pylons and substations to carry that cheap power to the people who need it - including to people in Scotland.

"Electricity demand is set to increase by 50% in the next decade and double by mid-century, so it's therefore wrong to say that Scottish households don't need more power lines, pylons and substations.

"We need them to ensure our lights stay on, as excess solar can strain networks in the same way consumers elsewhere in the UK need them.

"With abundant natural resources, Scotland's home-grown renewables can be at the heart of delivering the clean energy needed to end our reliance on imported, expensive fossil fuel.

"To do this, we need a national electricity grid capable of transmitting more electricity where and when it is needed, echoing New Zealand's electricity debate as well."

Nick Sharpe, director of communications and strategy at Scottish Renewables, said the current electricity network is "not fit for purpose".

He added: "Groups and individuals who object to the construction of power lines, pylons and substations largely do so because they do not like the way they look.

"By the end of this year, there will be just over 70 months left to achieve our targets of 11 gigawatts (GW) offshore and 12 GW onshore wind.

"To ensure we maximise the enormous socioeconomic benefits this will bring to local communities, we will need a grid fit for the 21st century."

Blackout-Prone California Is Exporting Its Energy Policies To Western States, Electricity Will Become More Costly And Unreliable

California Blackouts expose grid reliability risks as PG&E deenergizes lines during high winds. Mandated solar and wind displace dispatchable natural gas, straining ISO load balancing, transmission maintenance, and battery storage planning amid escalating wildfire liability.

 

Key Points

California grid shutoffs stem from wildfire risk, renewables, and deferred transmission maintenance under mandates.

✅ PG&E deenergizes lines to reduce wildfire ignition during high winds.

✅ Mandated solar and wind displace dispatchable gas, raising balancing costs.

✅ Storage, reliability pricing, and grid upgrades are needed to stabilize supply.

 

California is again facing widespread blackouts this season. Politicians are scrambling to assign blame to Pacific Gas & Electric (PG&E) a heavily regulated utility that can only do what the politically appointed regulators say it can do. In recent years this has meant building a bunch of solar and wind projects, while decommissioning reliable sources of power and scrimping on power line maintenance and upgrades.

The blackouts are connected with the legal liability from old and improperly maintained power lines being blamed for sparking fires—in hopes that deenergizing the grid during high winds reduces the likelihood of fires. 

How did the land of Silicon Valley and Hollywood come to have developing world electricity?

California’s Democratic majority, from Gov. Gavin Newsom to the solidly progressive legislature, to the regulators they appoint, have demanded huge increases in renewable energy. Renewable electricity targets have been pushed up, and policymakers are weighing a revamp of electricity rates to clean the grid, with the state expected to reach a goal of 33% of its power from renewable sources, mostly solar and wind, by next year, and 60% of its electricity from renewables by 2030.

In 2018, 31% of the electricity Californians purchased at the retail level came from approved renewables. But when rooftop solar is added to the mix, about 34% of California’s electricity came from renewables in 2018. Solar photovoltaic (PV) systems installed “behind-the-meter” (BTM) displace utility-supplied generation, but still affect the grid at large, as electricity must be generated at the moment it is consumed. PV installations in California grew 20% from 2017 to 2018, benefiting from the state’s Self-Generation Incentive Program that offers hefty rebates through 2025, as well as a 30% federal tax credit.

Increasingly large amounts of periodic, renewable power comes at a price—the more there is, the more difficult it is to keep the power grid stable and energized. Since electricity must be consumed the instant it is generated, and because wind and solar produce what they will whenever they do, the rest of the grid’s power producers—mostly natural gas plants—have to make up any differences between supply and immediate demand. This load balancing is vital, because without it, the grid will crash and widespread blackouts will ensue.

California often produces a surplus of mandated solar and wind power, generated for 5 to 8 cents per kilowatt hour. This power displaces dispatchable power from natural gas, coal and nuclear plants, resulting in reliable power plants spending less time online and driving up electricity prices as the plants operate for fewer hours of the day. Subsidized and mandated solar power, along with a law passed in California in 2006 (SB 1638) that bans the renewal of coal-fired power contracts, has placed enormous economic pressure on the Western region’s coal power plants—among them, the nation’s largest, Navajo Generating Station. As these plants go off line, the Western power grid will become increasingly unstable. Eventually, the states that share their electric power in the Western Interconnect may have to act to either subsidize dispatchable power or place a value on reliability—something that was taken for granted in the growth of the America’s electrical system and its regulatory scheme.

California law regarding electricity explicitly states that “a violation of the Public Utilities Act is a crime” and that it is “…the intent of the Legislature to provide for the evolution of the ISO (California’s Independent System Operator—the entity that manages California’s grid) into a regional organization to promote the development of regional electricity transmission markets in the western states.” In other words, California expects to dictate how the Western grid operates.

One last note as to what drives much of California’s energy policy: politics. California State Senator Kevin de León (the author served with him in the State Assembly) drafted SB 350, the Clean Energy and Pollution Reduction Act. It became law in 2015. Sen. de León followed up with SB 100 in 2018, signed into law weeks before the 2018 election. SB 100 increased California’s renewable portfolio standard to 60% by 2030 and further requires all the state’s electricity to come from carbon-free sources by 2045, a capstone of the state’s climate policies that factor into the blackout debate.  

Sen. de León used his environmental credentials to burnish his run for the U.S. Senate against Sen. Dianne Feinstein, eventually capturing the endorsements of the California Democratic Party and billionaire environmentalist Tom Steyer, now running for president. Feinstein and de León advanced to the general in California’s jungle primary, where Feinstein won reelection 54.2% to 45.8%.

De León may have lost his race for the U.S. Senate, but his legacy will live on in increasingly unaffordable electricity and blackouts, not only in California, but in the rest of the Western United States—unless federal or state regulators begin to place a value on reliability. This could be done by requiring utility scale renewable power providers to guarantee dispatchable power, as policymakers try to avert a looming shortage of firm capacity, either through purchase agreements with thermal power plants or through the installation of giant and costly battery farms or other energy storage means.

BC Hydro: 2021 was a record-breaking year for electricity demand

BC Hydro 2021 Peak Load Records highlight record-breaking electricity demand, peak load spikes, heat dome impacts, extreme cold, and shifting work-from-home patterns managed by a flexible hydroelectric system and climate-driven load trends.

 

Key Points

Record-breaking electricity demand peaks from extreme heat and cold that reshaped daily load patterns across BC in 2021.

✅ Heat dome and deep freeze drove sustained peak electricity demand

✅ Peak load built gradually, reflecting work-from-home behavior

✅ Flexible hydroelectric system adapts quickly to demand spikes

 

From June’s heat dome to December’s extreme cold, 2021 was a record-setting year, according to BC Hydro, and similar spikes were noted as Calgary's electricity use surged in frigid weather.

On Friday, the energy company released a new report on electricity demand, and how extreme temperatures over extended periods of time, along with growing scrutiny of crypto mining electricity use, led to record peak loads.

“We use peak loads to describe the electricity demand in the province during the highest load hour of each day,” Kyle Donaldson, BC Hydro spokesperson, said in a media release.

“With the heat dome in the summer and the sustained cold temperatures in December, we saw more record-breaking hours on more days last year than any other single year.”

According to BC Hydro, during summer, the Crown corporation recorded 19 of its top 25 all-time summer daily peak records — including breaking its all-time summer peak hourly demand record.

In December, which saw extremely cold temperatures and heavy snowfall, BC Hydro said its system experienced the highest and longest sustained load levels ever, as it activated its winter payment plan to assist customers.

Overall, BC Hydro says it has experienced 11 of its top 25 all-time daily peak records this winter, adding that Dec. 27 broke its all-time high peak hourly demand record.

“BC Hydro’s hydroelectric system is directly impacted by variations in weather, including drought conditions that require adaptation, and in 2021 more electricity demand records were broken than any other year prior, largely because of the back-to-back extreme temperatures lasting for days and weeks on end,” reads the report.

The energy company expects this trend to continue, noting that it has broken the peak record five times in the past five years, and other jurisdictions such as Quebec consumption record have also shattered consumption records.

It also noted that peak demand patterns have also changed since the first year of the COVID-19 pandemic, with trends seen during Earth Hour usage offering context.

“When the previous peak hourly load record was broken in January 2020, load displayed sharper increases and decreases throughout the day, suggesting more typical weather and behaviour,” said the report.

“In contrast, the 2021 peak load built up more gradually throughout the day, suggesting more British Columbians were likely working from home, or home for the holidays – waking up later and home earlier in the evening – as well as colder weather than average.”

BC Hydro also said “current climate models suggest a warming trend continuing in years to come which could increase demand year-round,” but noted that its flexible hydroelectric system can meet changes in demand quickly.
