U.S. adds wind energy to 400,000 homes

Medicine Hat Bitcoin Mining Deal delivers 42 MW electricity to Hut 8, enabling blockchain data centres, cryptocurrency mining expansion, and economic diversification in Alberta with low-cost power, land lease, and rapid construction near Unit 16.

Key Points

A pact to supply 42 MW and lease land, enabling Hut 8's blockchain data centres and crypto mining growth in Alberta.

✅ 42 MW electricity from city; land lease near Unit 16

✅ Hut 8 expands to 60.7 MW; blockchain data centres

✅ 100 temporary jobs; 42 ongoing roles in Alberta

The City of Medicine Hat has agreed to supply electricity and lease land to a Toronto-based cryptocurrency mining company, at a time when some provinces are pausing large new crypto loads in a deal that will see $100 million in construction spending in the southern Alberta city.

The city will provide electric energy capacity of about 42 megawatts to Hut 8 Mining Corp., which will construct bitcoin mining facilities near the city's new Unit 16 power plant.

The operation is expected to be running by September and will triple the company's operating power to 60.7 megawatts, Hut 8 said, amid broader investments in new turbines across Canada.

"The signing of the electricity supply agreement and the land lease represents a key component in achieving our business plan for the roll-out of our BlockBox Data Centres in low-cost energy jurisdictions," said the company's board chairman, Bill Tai, in a release.

"[Medicine Hat] offers stable, cost-competitive utility rates and has been very welcoming and supportive of Hut 8's fast-paced growth plans."

In bitcoin mining operations, rows upon rows of power-consuming computers are used to solve mathematical puzzles in exchange for bitcoins and confirm crytopcurrency transactions. The verified transactions are then added to the public ledger known as the blockchain.

Hut 8's existing 18.7-megawatt mining operation at Drumheller, Alta. — a gated compound filled with rows of shipping containers housing the computers — has so far mined 750 bitcoins. Bitcoin was trading Tuesday morning for about $11,180.

Medicine Hat Mayor Ted Clugston says the deal is part of the city's efforts to diversify its economy.

We've made economic development a huge priority down here because we were hit very, very hard by the oil and gas decline," he said, noting that being the generator and vendor of its own electricity puts the city in a uniquely good position.

"Really we're just turning gas into electricity and they're taking that electricity and turning it into blockchain, or ones and zeroes."

Elsewhere in Canada, using more electricity for heat has been urged by green energy advocates, reflecting broader electrification debates.

Hut 8 says construction of the facility is starting right away and will create about 100 temporary jobs. The project is expected to be finished by the third-quarter of this year.

The Medicine Hat mining operation will generate 42 ongoing jobs for electricians, general labourers, systems technicians and security staff.

China Power Demand-Emissions Gap highlights surging grid demand outpacing renewables, with coal filling shortages despite record solar, wind, EV charging, and hydrogen growth, threatening decarbonization targets and net-zero pathways through 2030.

Key Points

China's power demand outpaces renewables, keeping coal dominant and raising emissions risk through the 2020s.

✅ Record solar and wind still lag fast grid demand growth

✅ Coal fills gaps as EV charging and hydrogen loads rise

✅ Forecasts diverge: CEC bullish vs IEA, BNEF conservative

Here’s a new obstacle that could prevent the world finally turning the corner on climate change: Imagine that over the coming decade a whole new economy the size of Russia were to pop up out of nowhere. With the world’s fourth-largest electricity sector and largest burden of power plant emissions after China, the U.S. and India, this new economy on its own would be enough to throw out efforts to halt global warming — especially if it keeps on growing through the 2030s.

That’s the risk inherent in China’s seemingly insatiable appetite for grid power, as surging electricity demand is putting systems under strain worldwide.

From the cracking pace of renewable build-out last year, you might think the country had broken the back of its carbon addiction. A record 55 gigawatts of solar power and 48 gigawatts of wind were connected — comparable to installing the generation capacity of Mexico in less than 12 months. This year will see an even faster pace, with 93 GW of solar and 50 GW of wind added, according to a report last week from the China Electricity Council, an industry association.

That progress could in theory see the country’s power sector emissions peak within months, rather than the late-2020s date the government has hinted at. Combined with a smaller quantity of hydro and nuclear, low-emissions sources will probably add about 310 terawatt-hours to zero-carbon generation this year. That 3.8% increase would be sufficient to power the U.K.

Countries that have reached China’s levels of per-capita electricity consumption (already on a par with most of Europe) typically see growth rates at less than half that level, even as global power demand has surged past pre-pandemic levels in recent years. Grid supply could grow at a faster pace than Brazil, Iran, South Korea or Thailand managed over the past decade without adding a ton of additional carbon to the atmosphere.

There’s a problem with that picture, however. If electricity demand grows at an even more headlong pace, there simply won’t be enough renewables to supply the grid. Fossil fuels, overwhelmingly coal, will fill the gap, a reminder of the iron law of climate dynamics in energy transitions.

Such an outcome looks distinctly possible. Electricity consumption in 2021 grew at an extraordinary rate of 10%, and will increase again by between 5% and 6% this year, according to the CEC. That suggests the country is on pace to match the CEC’s forecasts of bullish grid demand over the coming decade, with generation hitting 11,300 terawatt-hours in 2030. External analysts, such as the International Energy Agency and BloombergNEF, envisage a more modest growth to around 10,000 TWh. 

The difference between those two outlooks is vast — equivalent to all the electricity produced by Russia or Japan. If the CEC is right and the IEA and BloombergNEF are wrong, even the furious rate of renewable installations we’re seeing now won’t be enough to rein in China’s power-sector emissions.

Who’s correct? On one hand, it’s fair to say that power planners usually err on the side of overestimation. If your forecast for electricity demand is too high, state-owned generators will be less profitable than they otherwise would have been — but if it’s too low, you’ll see power cuts and shutdowns like China witnessed last autumn, with resulting power woes affecting supply chains beyond its borders.

On the other hand, the decarbonization of China’s economy itself should drive electricity demand well above what we’ve seen in the past, with some projections such as electricity meeting 60% of energy use by 2060 pointing to a profound shift. Some 3.3 million electric vehicles were sold in 2021 and BloombergNEF estimates a further 5.7 million will be bought in 2022. Every million EVs will likely add in the region of 2 TWh of load to the grid. Those sums quickly mounts up in a country where electric drivetrains are taking over a market that shifts more than 25 million new cars a year.

Decarbonizing industry, a key element on China’s road to zero emissions, could also change the picture. The IEA sees the country building 25 GW of electolysers to produce hydrogen by 2030, enough to consume some 200 TWh on their own if run close to full-time.

That’s still not enough to justify the scale of demand being forecast, though. China is already one of the least efficient countries in the world when it comes to translating energy into economic growth, and despite official pressure on the most wasteful, so called “dual-high” industries such as steel, oil refining, glass and cement, its targets for more thrifty energy usage remain pedestrian.

The countries that have decarbonized fastest are those, such as Germany, the U.K and the U.S., where Americans are using less electricity, that have seen power demand plateau or even decline, giving new renewable power a chance to swap out fossil-fired generators without chasing an ever-increasing burden on the grid. China’s inability to do this as its population peaks and energy consumption hits developed-country levels isn’t a sign of strength.

Instead, it’s a sign of a country that’s chronically unable to make the transition away from polluting heavy industry and toward the common prosperity and ecological civilization that its president keeps promising. Until China reins in that credit-fueled development model, the risks to its economy and the global climate will only increase.

U.S. Power Sector Outlook 2022 previews clean energy targets, grid reliability and resilience upgrades, transmission expansion, renewable integration, EV charging networks, and decarbonization policies shaping utilities, markets, and climate strategies amid extreme weather risks.

Key Points

An outlook on clean energy goals, grid resilience, transmission, and EV infrastructure shaping U.S. decarbonization.

✅ States set 100% clean power targets; equity plans deepen.

✅ Grid reforms, transmission builds, and RTO debates intensify.

✅ EV plants, batteries, and charging corridors accelerate.

As sweeping climate legislation stalled in Congress this year, states and utilities were busy aiming to reshape the future of electricity.

States expanded clean energy goals and developed blueprints on how to reach them. Electric vehicles got a boost from new battery charging and factory plans.

The U.S. power sector also is sorting through billions of dollars of damage that will be paid for by customers over time. States coped with everything from blackouts during a winter storm to heat waves, hurricanes, wildfires and tornadoes. The barrage has added urgency to a push for increased grid reliability and resilience, especially as the power generation mix evolves, EV grid challenges grow as electricity is used to power cars and the climate changes.

“The magnitude of our inability to serve with these sort of discontinuous jumps in heat or cold or threats like wildfires and flooding has made it really clear that we can’t take the grid for granted anymore — and that we need to do something,” said Alison Silverstein, a Texas-based energy consultant.

Many of the announcements in 2021 could see further developments next year as legislatures, utilities and regulators flesh out details on everything from renewable projects to ways to make the grid more resilient.

On the policy front, the patchwork of state renewable energy and carbon reduction goals stands out considering Congress’ failure so far to advance a key piece of President Biden’s agenda — the "Build Back Better Act," which proposed about $550 billion for climate action. Criticism from fellow Democrats has rained on Sen. Joe Manchin (D-W.Va.) since he announced his opposition this month to that legislation (E&E Daily, Dec. 21).

The Biden administration has taken some steps to advance its priorities as it looks to decarbonize the U.S. power sector by 2035. That includes promoting electric vehicles, which are part of a goal to make the United States have net-zero emissions economywide no later than 2050. The administration has called for a national network of 500,000 EV charging stations as the American EV boom raises power-supply questions, and mandated the government begin buying only EVs by 2035.

Still, the fate of federal legislation and spending is uncertain. States and utility plans are considered a critical factor in whether Biden’s targets come to fruition. Silverstein also stressed the importance of regional cooperation as policymakers examine the grid and challenges ahead.

“Our comfort as individuals and as households and as an economy depends on the grid staying up,” Silverstein said, “and that’s no longer a given.”

Here are three areas of the electricity sector that saw changes in 2021, and could see significant developments next year:

1. Clean energy
The list of states with new or revamped clean energy goals expanded again in 2021, with Oregon and Illinois joining the ranks requiring 100 percent zero-carbon electricity in 2040 and 2050, respectively.

Washington state passed a cap-and-trade bill. Massachusetts and Rhode Island adopted 2050 net-zero goals.

North Carolina adopted a law requiring a 70 percent cut in carbon emissions by 2030 from 2005 levels and establishing a midcentury net-zero goal.

Nebraska didn’t adopt a statewide policy, but its three public power districts voted separately to approve clean energy goals, actions that will collectively have the same effect. Even the governor of fossil-fuel-heavy North Dakota, during an oil conference speech, declared a goal of making the state carbon-neutral by the end of the decade.

These and other states join hundreds of local governments, big energy users and utilities, which were also busy establishing and reworking renewable energy and climate goals this year in response to public and investor pressure.

However, many of the details on how states will reach those targets are still to be determined, including factors such as how much natural gas will remain online and how many renewable projects will connect to the grid.

Decisions on clean energy that could be made in 2022 include a key one in Arizona, which has seen support rise and fall over the years for a proposal to lead to 100 percent clean power for regulated electric utilities. The Arizona Corporation Commission could discuss the matter in January, though final approval of the plan is not a sure thing. Eyes also are on California, where a much bigger grid for EVs will be needed, as it ponders a recent proposal on rooftop solar that has supporters of renewables worried about added costs that could hamper the industry.

In the wake of the major energy bill North Carolina passed in 2021, observers are waiting for Duke Energy Corp.’s filing of its carbon-reduction plan with state utility regulators. That plan will help determine the future electricity mix in the state.

Warren Leon, executive director of the Clean Energy States Alliance (CESA), said that without federal action, state goals are “going to be more difficult to achieve.”

State and federal policies are complementary, not substitutes, he said. And Washington can provide a tailwind and help states achieve their goals more quickly and easily.

“Progress is going to be most rapid if both the states and the federal government are moving in the same direction, but either of them operating independently of the others can still make a difference,” he said.

While emissions reductions and renewable energy goals were centerpieces of the state energy and climate policies adopted this year, there were some other common threads that could continue in 2022.

One that’s gone largely unnoticed is that an increasing number of states went beyond just setting targets for clean energy and have developed plans, or road maps, for how to meet their goals, Leon said.

Like the New Year resolutions that millions of Americans are planning — pledges to eat healthier or exercise more — it’s far easier to set ambitious goals than to achieve them.

According to CESA, California, Colorado, Nevada, Maine, Rhode Island, Massachusetts and Washington state all established plans for how to achieve their clean energy goals. Prior to late 2020, only two states — New York and New Jersey — had done so.

Another trend in state energy and climate policies: Equity and energy justice provisions factored heavily in new laws in places such as Maine, Illinois and Oregon.

Equity isn’t a new concern for states, Leon said. But state plans have become more detailed in terms of their response to ways the energy transition may affect vulnerable populations.

“They’re putting much more concrete actions in place,” he said. “And they are really figuring out how they go about electricity system planning to make sure there are new voices at the table, that the processes are different, and there are things that are going to be measured to determine whether they’re actually making progress toward equity.”

2. Grid
Climate change and natural disasters have been a growing worry for grid planners, and 2021 was a year the issue affected many Americans directly.

Texas’ main power grid suffered massive outages during a deadly February winter storm, and it wasn’t far from an uncontrolled blackout that could have required weeks or months of recovery.

Consumers elsewhere in the country watched as millions of Texans lost grid power and heat amid a bitter cold snap. Other parts of the central United States saw more limited power outages in February.

“I think people care about the grid a lot more this year than they did last year,” Silverstein said, adding, “All of a sudden people are realizing that electricity’s not as easy as they’ve assumed it was and … that we need to invest more.”

Many of the challenges are not specific to one state, she added.

“It seems to me that the state regulators need to put a lot — and utilities need to put a lot — more commitment into working together to solve broad regional problems in cooperative regional ways,” Silverstein said.

In 2022, multiple decisions could affect the grid, including state oversight of spending on upgrades and market proposals that could sway the amount of clean energy brought online.

A focal point will be Texas, where state regulators are examining further changes to the Electric Reliability Council of Texas’ market design. That could have major implications for how renewables develop in the state. Leaders in other parts of the country will likely keep tabs on adjustments in Texas as they ponder their own changes.

Texas has already embarked on reforms to help improve the power sector and its coordination with the natural gas system, which is critical to keeping plants running. But its primary power grid, operated by ERCOT, remains largely isolated and hasn’t been able to rule out power shortages this winter if there are extreme conditions (Energywire, Nov. 22).

Transmission also remains a key issue outside of the Lone Star State, both for resilience and to connect new wind and solar farms. In many areas of the country, the job of planning these new regional lines and figuring out how to allocate billions of dollars in costs falls to regional grid operators (Energywire, Dec. 13).

In the central U.S., the issue led to tension between states in the Midwest and the Gulf South (Energywire, Oct. 15).

In the Northeast, a Maine environmental commissioner last month suspended a permit for a major transmission project that could send hydropower to the region from Canada (Greenwire, Nov. 24). The project’s developers are now battling the state in court to force construction of the line — a process that could be resolved in 2022 — after Mainers signaled opposition in a November vote.

Advocates of a regional transmission organization for Western states, meanwhile, hope to keep building momentum even as critics question the cost savings promoted by supporters of organized markets. Among those in existing markets, states such as Louisiana are expected to monitor the costs and benefits of being associated with the Midcontinent Independent System Operator.

In other states, more details are expected to emerge in 2022 about plans announced this year.

In California, where policymakers are also exploring EVs for grid stability alongside wildfire prevention, Pacific Gas & Electric Co. announced a plan over the summer to spend billions of dollars to underground some 10,000 miles of power lines to help prevent wildfires, for example (Greenwire, July 22).

Several Southeastern utilities, including Dominion Energy Inc., Duke Energy, Southern Co. and the Tennessee Valley Authority, won FERC approval to create a new grid plan — the Southeast Energy Exchange Market, or SEEM — that they say will boost renewable energy.

SEEM is an electricity trading platform that will facilitate trading close to the times when the power is used. The new market is slated to include two time zones, which would allow excess renewables such as solar and wind to be funneled to other parts of the country to be used during peak demand times.

SEEM is significant because the Southeast does not have an organized market structure like other parts of the country, although some utilities such as Dominion and Duke do have some operations in the region managed by PJM Interconnection LLC, the largest U.S. regional grid operator.

SEEM is not a regional transmission organization (RTO) or energy imbalance market. Critics argue that because it doesn’t include a traditional independent monitor, SEEM lacks safeguards against actions that could manipulate energy prices.

Others have said the electric companies that formed SEEM did so to stave off pressure to develop an RTO. Some of the regulated electric companies involved in the new market have denied that claim.

3. Electric vehicles
With electric vehicles, the Midwest and Southeast gained momentum in 2021 as hubs for electrifying the transportation sector, as EVs hit an inflection point in mainstream adoption, and the Biden administration simultaneously worked to boost infrastructure to help get more EVs on the road.

From battery makers to EV startups to major auto manufacturers, companies along the entire EV supply chain spectrum moved to or expanded in those two regions, solidifying their footprint in the fast-growing sector.

A wave of industry announcements capped off in December with California-based Rivian Automotive Inc. declaring it would build a $5 billion electric truck, SUV and van factory in Georgia. Toyota Motor Corp. picked North Carolina for its first U.S.-based battery plant. General Motors Co. and a partner plan to build a $2.5 billion battery plant in GM’s home state of Michigan. And Proterra Inc. has unveiled plans to build a new battery factory in South Carolina.

Advocates hope the EV shift by automakers in the Midwest and Southeast will widen the options for customers. Automakers and startups also have been targeting states with zero-emission vehicle targets to launch new and more models because there’s an inherent demand for them.

“The states that have adopted those standards are getting more vehicles,” said Anne Blair, senior EV policy manager for the Electrification Coalition.

EV advocates say they hope those policies could help bring products like Ford’s electrified signature truck line on the road and into rural areas. Ford also is partnering with Korean partner SK Innovation Co. Ltd. to build two massive battery plants in Kentucky.

Regardless of the fanfare about new vehicles, more jobs and must-needed economic growth, barriers to EV adoption remain. Many states have tacked on annual fees, which some elected officials argue are needed to replace revenues secured from a gasoline tax.

Other states do not allow automakers to sell directly to consumers, preventing companies like Lordstown Motors Corp. and Rivian to effectively do business there.

“It’s about consumer choice and consumers having the capacity to buy the vehicles that they want and that are coming out, in new and innovative ways,” Blair told E&E News. Blair said direct sales also will help boost EV sales at traditional dealerships.

In 2022, advocates will be closely watching progress with the National Electric Highway Coalition, amid tensions over charging control among utilities and networks, which was formed by more than 50 U.S. power companies to build a coast-to-coast fast-charging network for EVs along major U.S. travel corridors by the end of 2023 (Energywire, Dec. 7).

A number of states also will be holding legislative sessions, and they could include new efforts to promote EVs — or change benefits that currently go to owners of alternative vehicles.

EV advocates will be pushing for lawmakers to remove barriers that they argue are preventing customers from buying alternative vehicles.

Conversations already have begun in Georgia to let startup EV makers sell their cars and trucks directly to consumers. In Florida, lawmakers will try again to start a framework that will create a network of charging stations as charging networks jostle for position under federal electrification efforts, as well as add annual fees to alternative vehicles to ease concerns over lost gasoline tax revenue.

BC Hydro COVID-19 Bill Relief provides payment deferrals, no-penalty payment plans, Crisis Fund grants up to $600, and utility bill assistance as customers face pandemic layoffs, social distancing, and increased home power usage.

Key Points

A BC Hydro program offering bill deferrals, no-penalty plans, and up to $600 Crisis Fund grants during COVID-19.

✅ Defer payments or set no-penalty payment plans

✅ Apply for up to $600 Customer Crisis Fund grants

✅ Measures to ensure reliable power and remote customer service

BC Hydro is implementing a program, including bill relief measures, to help people pay their bills if they’re affected by the novel coronavirus.

The Crown corporation says British Columbians are facing a variety of financial pressures related to the COVID-19 pandemic, as some workplaces close or reduce staffing levels and commercial power consumption plummets across the province.

BC Hydro said it also expects increased power usage as more people stay home amid health officials’ requests that people take social distancing measures, even as electricity demand is down 10% provincewide.

Under the new program, customers will be able to defer bill payments or arrange a payment plan with no penalty, though a recent report on deferred operating costs outlines long-term implications for the utility.

BC Hydro says some customers could also be eligible for grants of up to $600 under its Customer Crisis Fund, if facing power disconnection due to job loss, illness or loss of a family member, while in other jurisdictions power bills were cut for households during the pandemic.

The company says it has taken precautions to keep power running by isolating key facilities, including its control centre, and by increasing its cleaning schedule, a priority even as some utilities face burgeoning debt amid COVID-19.

It has also closed its walk-in customer service desks to reduce risk from face-to-face contact and suspended all non-essential business travel, public meetings and site tours, and warned businesses about BC Hydro impersonation scams during this period.

Iran Renewable Energy Strategy targets productivity first, then wind power expansion, investment, and exports, overcoming US sanctions, banking and forex limits, via private sector partnerships, precise wind maps, and regional grid interconnections.

Key Points

A policy prioritizing efficiency, wind deployment, and investor access while navigating US sanctions and currency limits.

✅ Prioritize efficiency, then scale wind generation capacity

✅ Leverage private sector, rial contracts, attract foreign capital

✅ Map high-wind corridors: Zabol, Khaf, Doroud; target exports

Deputy Energy Minister on Renewable Energies Affairs says the U.S. sanctions have currently affected the economic, banking and forex sectors of the country as the country‘s medicine is under sanctions and it means renewable energies are also under sanctions, and, globally, pandemic disruptions have compounded pressures on supply chains.

Speaking in a press conference yesterday, Mohammad Satkin said leading countries first focus on productivity then they turn to electricity production and the ministry in the first step has focused on productivity then on renewables, noting that renewables are now the cheapest new power in many regions, reiterating that the ministry will use all existing potentials in this regard especially in utilizing wind.

He added that the ministry is doing its best that the country would become the hub in the region for rush of investors and those who want take advantage of Iran’s experience in renewables, as markets like the U.S. scale renewables to a quarter of generation in coming years.

Satkin added that in the eastern part, the country has the biggest windy fields with capacity over 40mw. So the ministry is doing its best with full support of the private sector in equipping and investing in this field to carry out new policies.

He noted that in the past 12 years, wind potentials of the country have been under study, noting that country has three special channels in the east as one of them is north of Zabol which is very valuable in terms of energy and it has capability for construction of 2 to 3mw power station.

Satkin further said Khaf channel is the other one which has one of the most unique winds in the world, while Saudi wind expansion underscores regional momentum, and it can be developed for over 1000mw station. The windy region of Doroud is the third channel where the 50mw project has been kicked off there and it has capability for construction of some thousand-megawatt wind power station.

He added that Iran has prepared one of the most precise maps and it has even identified the border regions like with Afghanistan and perhaps in the future, Iran and Afghanistan may launch a joint project as Iran has enough expertise to offer its neighboring countries and as IRENA's decarbonisation roadmap highlights wider socio-economic benefits.

On signing agreement with foreign companies, Satkin said the ministry pays the sum of all contracts with domestic companies is paid in national currency rial as it is unable to pay in dollar or other currencies but Iranian companies may enjoy having foreign backings, including initiatives like ADFD-IRENA funding that support developing markets, and the ministry tries to attract foreign capital.

He also pointed to exports of renewables, adding that the government has authorized export of renewable energy but it needs proper planning to be assured of electricity production in order to export it to the neighboring states whenever they need, especially as Ireland targets over one-third green power within a few years.

Ontario Electricity Demand 2020 shows a rare decline amid COVID-19, with higher residential peak load, lower commercial usage, hot-weather air conditioning, nuclear baseload constraints, and smart meter data shaping grid operations and forecasting.

Key Points

It refers to 2020 power use in Ontario: overall demand fell, while residential peaks rose and commercial loads dropped.

✅ Peak load shifted to homes; commercial usage declined.

✅ Hot summers raised peaks; overall annual demand still fell.

✅ Smart meters aid forecasting; grid must balance nuclear baseload.

Demand for electricity in Ontario last year fell to levels rarely seen in decades amid shifts in usage patterns caused by pandemic measures, with Ottawa’s electricity consumption dropping notably, new data show.

The decline came despite a hot summer that had people rushing to crank up the air conditioning at home, the province’s power management agency said, even as the government offered electricity relief to families and small businesses.

“We do have this very interesting shift in who’s using the energy,” said Chuck Farmer, senior director of power system planning with the Independent Electricity System Operator.

“Residential users are using more electricity at home than we thought they would and the commercial consumers are using less.”

The onset of the pandemic last March prompted stay-home orders, businesses to close, and a shuttering of live sports, entertainment and dining out. Social distancing and ongoing restrictions, even as the first wave ebbed and some measures eased, nevertheless persisted and kept many people home as summer took hold and morphed into winter, while the province prepared to extend disconnect moratoriums for residential customers.

System operator data show peak electricity demand rose during a hot summer spell to 24,446 megawatts _ the highest since 2013. Overall, however, Ontario electricity demand last year was the second lowest since 1988, the operator said.

In all, Ontario used 132.2 terawatt-hours of power in 2020, a decline of 2.9 per cent from 2019.

With more people at home during the lockdown, winter residential peak demand has climbed 13 per cent above pre-pandemic levels, even as Hydro One made no cut in peak rates for self-isolating customers, while summer peak usage was up 19 per cent.

“The peaks are getting higher than we would normally expect them to be and this was caused by residential customers _ they’re home when you wouldn’t expect them to be home,” Farmer said.

Matching supply and demand _ a key task of the system operator _ is critical to meeting peak usage and ensuring a stable grid, and the operator has contingency plans with some key staff locked down at work sites to maintain operations during COVID-19, because electricity cannot be stored easily. It is also difficult to quickly raise or lower the output from nuclear-powered generators, which account for the bulk of electricity in the province, as demand fluctuates.

Life patterns have long impacted overall usage. For example, demand used to typically climb around 10 p.m. each night as people tuned into national television newscasts. Livestreaming has flattened that bump, while more energy-efficient lighting led to a drop in provincial demand over the holiday season.

The pandemic has now prompted further intra-day shifts in usage. Fewer people are getting up in the morning and powering up at home before powering down and rushing off to work or school. The summer saw more use of air conditioners earlier than normal after-work patterns.

Weather has always been a key driver of demand for power, accounting for example for the record 27,005 megawatts of usage set on a brutally hot Aug. 1, 2006. Similarly, a mild winter and summer led to an overall power usage drop in 2017.

Still, the profound social changes prompted by the COVID-19 pandemic _ and whether some will be permanent _ have complicated demand forecasting.

“Work patterns used to be much more predictable,” the agency said. “The pandemic has now added another element of variability for electricity demand forecasting.”

Some employees sent home to work have returned to their offices and other workplaces, and many others are likely do so once the pandemic recedes. However, some larger companies have indicated that working from home will be long term.

“Companies like Facebook and Shopify have already stated their intention to make work from home a more permanent arrangement,” the operator said. “This is something our near-term forecasters would take into account when preparing for daily operation of the grid.”

Aggregated data from better smart meters, which show power usage throughout the day, is one method of improving forecasting accuracy, the operator said.
