Alberta Electricity Demand Record surges during a deep freeze, as AESO reports peak load in megawatts and ENMAX notes increased usage in Calgary and Edmonton, with thermostats up amid a cold snap straining power grid.

Key Points

It is the highest electricity peak load recorded by AESO, reflecting maximum grid usage during cold snaps.

✅ AESO reported 11,729 MW peak during the deep freeze

✅ ENMAX saw a 13 percent demand jump week over week

✅ Cold snap drove thermostats up in Calgary and Edmonton

Albertans are cranking up their thermostats and blasting heat into their homes at overwhelmingly high rates as the deep freeze continues across the region. 

It’s so cold that the province set a new all-time record Tuesday evening for electricity usage. 

According to the Alberta Electric System Operator (AESO), as electricity prices spike in Alberta during extreme demand, 11,729 MW of power was used around 7 p.m. Tuesday, passing the previous record set in January of last year by 31 MW.

Temperatures reached a low of -29 C in Calgary, where rising electricity bills have strained budgets, on Tuesday while Edmonton saw a low of -30 C, according to Environment Canada. Wind chill  made it feel closer to -40.

“That increase — 31 Megawatts — is sizeable and about the equivalent of a moderately sized generation facility,” said AESO communications director, Mike Deising. 

“We do see higher demand in winter because it’s cold and it’s dark and that’s really exactly what we’re seeing right now as demand goes up, people turn on their lights and turn up their furnaces,” and with the UCP scrapping the price cap earlier that’s really exactly what we’re seeing right now as demand goes up, people turn on their lights and turn up their furnaces.”

Deising adds Alberta’s electricity usage over the last year has actually been much lower than average, though experts urge Albertans to lock in rates amid expected volatility, despite more people staying home during the pandemic. 

That trend was continuing into 2021, but as Alberta's rising electricity prices draw attention, it’s expected that more records could be broken. 

“If the cold snap continues we may likely set another record (Wednesday) or (Thursday), depending on what happens with the temperatures,” he said. 

Meanwhile, ENMAX has reported an average real-time system demand of 1,400 MW for the city of Calgary. 

That amount is still a far cry from the current season record of 1,619 MW (Aug. 18, 2020), the all-time winter record of 1,653MW (Dec. 2, 2013), and the all-time summer record of 1,692 MW (Aug. 10, 2018). 

ENMAX says electricity demand has increased quite significantly over the past week — by about 13 per cent — since the cold snap set in. 

As a result, the energy company is once again rolling out its ‘Winter Wise’ campaign in an effort to encourage Calgarians to manage both electricity and natural gas use in the winter, even as a consumer price cap on power bills is enabled by new legislation.

Hydro One CEO Mark Poweska aims to rebuild ties with Ontario's provincial government, investors, and communities, stabilize the executive team, boost earnings and dividends, and reset strategy after the scrapped Avista deal and regulatory setbacks.

Key Points

He plans to mend government and investor relations, rebuild the C-suite, and refocus growth after the failed Avista bid.

✅ Rebuild ties with Ontario government and regulators

✅ Stabilize executive team and governance

✅ Refocus growth after Avista deal termination

The incoming chief executive officer of Hydro One Ltd. said Thursday that he aims to rebuild the relationship between the Ontario electrical utility and the provincial government, as seen in COVID-19 support initiatives, as well as ties between the company and its investors.

Mark Poweska, the former executive vice-president of operations at BC Hydro, was announced as Hydro One’s new president and CEO in March. His hiring followed a turbulent period for Toronto-based Hydro One, Ontario’s biggest distributor and transmitter of electricity, with large-scale storm restoration efforts underscoring its role.

Hydro One’s former CEO and board of directors departed last year under pressure from a new Ontario government, the utility’s biggest shareholder. Earlier this year, the company’s plan for a $6.7-billion takeover fell apart over concerns of political interference and the utility clashed with the new provincial government and Progressive Conservative Premier Doug Ford over executive compensation levels, amid rate policy debates such as no peak rate cuts for self-isolating customers.

Hydro One facing $885 million charge as regulator upholds tax decision forcing it to share savings with customers

Shares of Hydro One were up more than eight per cent year-to-date on Wednesday, closing at $21.74. However, the stock price was up only six per cent from Hydro One’s 2015 initial public offering price, something its incoming CEO seems set on changing.

“One of my first priorities will be to solidify the executive team and build relationships with the Government of Ontario, our customers, informed by customer flexibility research, and communities, indigenous leaders, investors, and our partners across the electricity sector,” Poweska said Thursday on a conference call outlining Hydro One’s first-quarter results. “At the same time, I will be working to earn the trust and confidence of the investment community.”

Hydro One reported a profit of $171 million for the three months ended March 31, while peers such as Hydro-Québec reported pandemic-related losses as the sector adapted. Net income for the first quarter was down from $222 million a year earlier, which was due to $140 million in costs related to the scrapping of Hydro One’s proposed acquisition of U.S. energy company Avista Corp.

Hydro One Ltd. appointed Mark Poweska as President and CEO.

In January, Hydro One said the proposed takeover of Spokane, Wash.-headquartered Avista, an approximately $6.7-billion deal announced in July 2017, was being called off. As a result, Hydro One said it would pay Avista a US$103 million break fee.

Revenues net of purchased power for the first quarter rose to $952 million, up by 15.4 per cent compared to last year, Hydro One said, helped by higher distribution revenues. Adjusted profit for the quarter, which removes the Avista-related costs, was $311 million, up from $210 million a year ago.

The company is hiking its quarterly dividend to 24.15 cents per share, up five per cent from the last increase in May 2018, while also launching a pandemic relief fund for customers.

Poweska is taking over for acting president and CEO Paul Dobson this month, and the new executive will be charged with revamping Hydro One’s C-suite.

The company’s chief operating officer, chief legal officer, and chief corporate development officer have all departed this year. The company’s chief human resource officer has retired as well, although Poweska did announce Thursday that he had appointed acting chief financial officer Chris Lopez as CFO.

“Hydro One’s significant bench strength and management depth will ensure stability and continuity during this period of transition, as the sector pursues Hydro-Québec energy transition as well,” the company said in its first-quarter earnings press release.

Ontario remains Hydro One’s biggest shareholder, owning approximately 47 per cent of the company.

Lockdown Electricity Demand Trends reveal later mornings, weaker afternoons, and delayed peaks as WFH, streaming, and video conferencing reshape energy demand curves, grid forecasting, and residential electricity usage across Europe, New York, Tokyo, and Singapore.

Key Points

Shifts in power use during lockdowns: later ramps, weaker afternoons, and higher, delayed evening peaks.

✅ Morning ramp starts later; midday demand dips

✅ Evening peak shifts 1-2 hours; higher late-night usage

✅ WFH and streaming raise residential load; industrial demand falls

Life in lockdown means getting up late, staying up till midnight and slacking off in the afternoons.

That’s what power market data in Europe show in the places where restrictions on activity have led to a widespread shift in daily routines of hundreds of millions of people.

It’s a similar story wherever lockdowns bite. In New York City electricity use has fallen as much as 18% from normal times at 8am. Tokyo and three nearby prefectures had a 5% drop in power use during weekdays after Japan declared a state of emergency on April 7, according to Tesla Asia Pacific, an energy forecaster.

Italy’s experience shows the trend most clearly since the curbs started there on March 5, before any other European country. Data from the grid operator Terna SpA gives a taste of what other places are also now starting to report, with global daily demand dips observed in many markets as well.

1. People are sleeping later

With no commute to the office people can sleep longer. Normally, electricity demand began to pick up between 6 a.m. and 8 a.m. Now in Germany, it’s clear coffee machines don’t go on until between 8 a.m. and 9 a.m., said Simon Rathjen, founder of the trading company MFT Energy A/S.

Germany, France and Italy -- which between them make up almost two thirds of the euro-zone economy -- all have furlough measures that allow workers to receive a salary while temporarily suspended from their jobs. The U.K. also has a support package. Many of these workers will be getting up later.

"Now I have quite a relaxed start to the morning,” said David Freeman, an analyst in financial services from London. "I don’t get up until about half an hour before I need to start work.”

2. Less productive afternoons

There is a deeper dip in electricity use in the afternoons. Previously, power use rose between 2pm and 5pm. Now it dips as people head out for a walk or some air, according to UK demand data from National Grid Plc

It’s "as though we are living through a month of Sundays”, said Iain Staffell, senior lecturer in sustainable energy at Imperial College London.

3. Evenings in

From 6pm electricity use begins to rise steeply as people finish work and start chores. Restrictions like work and home schooling that prevent much daytime TV watching lifts in the early evening. This following chart for Germany shows the evening peak for power use coming during later hours.

The evening is when electricity use is highest, with most people confined to their homes. Netflix Inc reported a record 15.8 million paid subscribers – almost double the figure forecast by Wall Street analysts. Video-streaming services like Netflix and YouTube have found a captive audience. The new Disney+ service surpassed 50 million subscribers in just five months, a faster pace than predicted.

Internet traffic is skyrocketing, with a surge in bandwidth-intensive applications like streaming services and Zoom. This may mean that monthly broadband consumption of as much as 600 gigabytes, about 35% higher than before, according to Bloomberg Intelligence.

In Singapore, electricity use has dropped off significantly since the country’s "circuit-breaker” efforts to keep people at home began April 7. Electricity use has fallen and stayed low during the day. But late at night is a different story, as power demand fell sharply immediately after the lockdown began, it has steadily crept back in the past two weeks, perhaps a sign that Tiger King and The Last Dance have been finding late-night fans in the city state.

In Ottawa, COVID-19 closures made it seem as if the city had fallen off the electricity grid, according to local reports.

4. Staying up late

We’re going to bed later too. Demand doesn’t start to drop off until 10pm to 12am, at least an hour later than before.

"My children are definitely going to bed later,” said Liz Stevens, a teaching assistant from London. "Our whole routine is out the window.”

It’s challenging for those that need to predict behaviour – power grids and electricity traders. Forecasting is based on historical data, and there isn’t anything to go into the models gauging use now.

The closest we can get is looking at big events like football World Championships when people are all sitting down at the same time, according to Rathjen at MFT.

"Forecasting demand right now is very tricky,” said Chris Kimmett, director of power grids at Reactive Technologies Ltd. "A global pandemic is uncharted territory."

What normal looks like when the crisis passes is also an open question. Different countries are set to unravel their measures in their own ways, and global power demand has already surged above pre-pandemic levels in some analyses, with Germany and Austria loosening restrictions first and Italy remaining under tight control. Some changes may be permanent, with both workers and employers becoming more comfortable with working from home.

5. Different sectors consume more

In China, which is further along recovering from the pandemic than Europe or the US, the sharp contraction in overall power output masks a shift in daily routines.

Eating habits have changed. Restaurants are expanding delivery and even offering grocery services as the preference for dining at home persists. Household electricity consumption in China probably increased from activities such as cooking and heating, according to IHS Markit, which said that residential demand rose by 2.4% in the first two months as people stayed in.

The increase in technology use also drove China’s power demand from the telecom and web-service sectors to rise by 27%, the consultancy said.

Overall, China power demand in the first quarter of the year fell 6.5% from the same period in 2019 to 1.57 trillion kilowatt-hours, China’s National Energy Administration said last week. Industry uses about 70% of the country’s electricity, while the commercial sector and households account for 14% each. – Bloomberg

Irving Oil hydrogen electrolyzer expands green hydrogen capacity at the Saint John refinery with Plug Power technology, cutting carbon emissions, enabling clean fuel for buses, and supporting Atlantic Canada decarbonization and renewable grid integration.

Key Points

A 5 MW Plug Power unit at Irving's Saint John refinery producing low-carbon hydrogen via electrolysis.

✅ Produces 2 tonnes/day, enough to fuel about 60 hydrogen buses

✅ Uses grid power; targets cleaner supply via renewables and nuclear

✅ First Canadian refinery investing in electrolyzer technology

Irving Oil is expanding hydrogen capacity at its Saint John, N.B., refinery in a bid to lower carbon emissions and offer clean energy to customers.

The family-owned company said Tuesday it has a deal with New York-based Plug Power Inc. to buy a five-megawatt hydrogen electrolyzer that will produce two tonnes of hydrogen a day — equivalent to fuelling 60 buses with hydrogen — using electricity from the local grid and drawing on examples such as reduced electricity rates proposed in Ontario to grow the hydrogen economy.

Hydrogen is an important part of the refining process as it's used to lower the sulphur content of petroleum products like diesel fuel, but most refineries produce hydrogen using natural gas, which creates carbon dioxide emissions and raises questions explored in hydrogen's future for power companies in the energy sector.

"Investing in a hydrogen electrolyzer allows us to produce hydrogen in a very different way," Irving director of energy transition Andy Carson said in an interview.

"Instead of using natural gas, we're actually using water molecules and electricity through the electrolysis process to produce ... a clean hydrogen."

Irving plans to continue to work with others in the province to decarbonize the grid amid pressures like Ontario's push into energy storage as electricity supply tightens and ensure the electricity being used to power its hydrogen electrolyzer is as clean as possible, he said.

N.B. Power's electrical system includes 14 generating stations powered by hydro, coal, oil, wind, nuclear and diesel. The utility has committed to increasing its renewable energy sources and exploring innovations such as EV-to-grid integration piloted in Nova Scotia.

Irving said it will be the first oil refinery in Canada to invest in electrolyzer technology, as Ontario's Hydrogen Innovation Fund supports broader deployment nationwide.

The company said its goal is to offer hydrogen fuelling infrastructure in Atlantic Canada, complementing N.L.'s fast-charging network for EV drivers in the region.

"This kind of investment allows us to not just move to a cleaner form of hydrogen in the refinery. It also allows us to store and make hydrogen available to the marketplace," Carson said.

Federal watchdog warns Canada's 2030 emissions target may not be achievable
The hydrogen technology will help Irving "unlock pent up demand for hydrogen as an energy transition fuel for logistics organizations," he said.

Alberta also aims to expand its hydrogen production over the coming years, alongside British Columbia's $900 million hydrogen project moving ahead on the West Coast. 

Those plans lean on the development of carbon capture and storage (CCS) technology that aims to trap the emissions created when producing hydrogen from natural gas.

Ultra-Low Overnight Price Plan delivers flexible electricity pricing from Hydro One and the Ontario Energy Board, with TOU, tiered options, off-peak EV charging savings, balanced billing, and an online calculator to optimize bills.

Key Points

An Ontario pricing option with ultra-low night rates, helping Hydro One customers save by shifting usage to off-peak.

✅ Four periods with ultra-low overnight rate for EV charging

✅ Compare TOU vs tiered with Hydro One's online calculator

✅ Balanced billing and due date choice support budget control

Hydro One has announced that customers have even more choice and flexibility when it comes to how they are billed for electricity with the company's launch of the Ontario Energy Board's new Ultra-Low Overnight Electricity Price Plan for customers. A new survey of Ontario customers, conducted by Innovative Research Group, shows that 74 per cent of Ontarians find having choice between electricity pricing plans useful.

"As their trusted energy advisor, we want our customers to know we have the insights and tools to help them make the right choice when it comes to their electricity plans," said Teri French, Executive Vice President, Safety, Operations and Customer Experience. "We know that choice and flexibility are important to our customers, and we are proud to now offer them a third option so they can select the plan that best fits their lifestyle."

The same survey revealed that fewer than half of Ontarians are familiar with either tiered or the new ultra-low overnight price plans. To better support its customers Hydro One is providing an online calculator to help them choose which pricing plan best suits their lifestyle. The company also offers additional flexibility and assistance in managing household budgets by providing customers with the ability to choose their billing due date and flatten usage spikes from temperature fluctuations through balanced billing.

During the pandemic, Ontario introduced electricity relief to support families, small businesses and farms, complementing these customer options.

"By offering families and small businesses more choice, we are putting them back in control of their energy bills," said Todd Smith, Minister of Energy. "Starting today Hydro One customers have a new option - the Ultra-Low Electricity Price Plan - which could help them save money each year, while making our province's grid more efficient."

Electricity price plan options

• New Ultra-Low Overnight price plan (ULO): Designed for customers who use more electricity at night, such as those who charge their electric vehicle, this new price plan can help customers keep costs down and take control of their electricity bill by shifting usage to the ultra-low overnight price period and related off-peak electricity rates when province-wide electricity demand is lower.
• This plan has four price periods that are the same in the summer as they are in the winter and includes an ultra-low overnight rate.
• Time-of-Use price plan (TOU): TOU provides customers with more control over their electricity bill by adjusting their usage habits with time-of-use rates used in other jurisdictions as well.
• In this plan, electricity prices change throughout each weekday, when demand is on-peak, and peak hydro rates can affect overall costs.
• Tiered price plan (RPP): Tiered pricing provides customers with the flexibility to use electricity at any time of day at the same low price up until the threshold is exceeded during the month, after that usage is charged at a higher price.
• For residential customers, the winter period (November 1 – April 30) threshold is 1,000 kWh per month and the summer period (May 1 – October 31) threshold is 600 kWh per month. 
• For small business customers, the threshold is 750 kWh throughout the year, while broader stable electricity pricing supports industrial and commercial companies.

California Rolling Blackouts expose grid reliability risks amid a heatwave, as CAISO curtails power while solar output fades at sunset, wind stalls, and scarce natural gas and nuclear capacity plus PG&E issues strain imports.

Key Points

Grid outages during heatwaves from low reserves, fading solar, weak wind, and limited firm capacity.

✅ Heatwave demand rose as solar output dropped at sunset

✅ Limited imports and gas, nuclear shortfalls cut reserves

✅ Policy, pricing, and maintenance gaps increased outage risk

Millions of Californians were denied electrical power and thus air conditioning during a heatwave, raising the risk of heatstroke and death, particularly among the elderly and sick. 

The blackouts come at a time when people, particularly the elderly, are forced to remain indoors due to Covid-19, and as later heat waves would test the grid again statewide.

At first, the state’s electrical grid operator last night asked customers to voluntarily reduce electricity use. But after lapses in power supply pushed reserves to dangerous levels it declared a “Stage 3 emergency” cutting off power to people across the state at 6:30 pm.

The immediate reason for the black-outs was the failure of a 500-megawatt power plant and an out-of-service 750-megawatt unit not being available. “There is nothing nefarious going on here,” said a spokeswoman for California Independent System Operator (CAISO). “We are just trying to run the grid.”

But the underlying reasons that California is experiencing rolling black-outs for the second time in less than a year stem from the state’s climate policies, which California policymakers have justified as necessary to prevent deaths from heatwaves, and which it is increasingly exporting to Western states as a model.

In October, Pacific Gas and Electric cut off power to homes across California to avoid starting forest fires after reports that its power lines may have started fires in recent seasons. The utility and California’s leaders had over the previous decade diverted billions meant for grid maintenance to renewables. 

And yesterday, California had to impose rolling blackouts because it had failed to maintain sufficient reliable power from natural gas and nuclear plants, or pay in advance for enough guaranteed electricity imports from other states.

It may be that California’s utilities and their regulator, the California Public Utilities Commission, which is also controlled by Gov. Newsom, didn’t want to spend the extra money to guarantee the additional electricity out of fears of raising California’s electricity prices even more than they had already raised them.

California saw its electricity prices rise six times more than the rest of the United States from 2011 to 2019, helping explain why electricity prices are soaring across the state, due to its huge expansion of renewables. Republicans in the U.S. Congress point to that massive increase to challenge justifications by Democrats to spend $2 trillion on renewables in the name of climate change.

Even though the cost of solar panels declined dramatically between 2011 and 2019, their unreliable and weather-dependent nature meant that they imposed large new costs in the form of storage and transmission to keep electricity as reliable. California’s solar panels and farms were all turning off as the blackouts began, with no help available from the states to the East already in nightfall.

Electricity from solar goes away at the very moment when the demand for electricity rises. “The peak demand was steady in late hours,” said the spokesperson for CAISO, which is controlled by Gov. Gavin Newsom, “and we had thousands of megawatts of solar reducing their output as the sunset.”

The two blackouts in less than a year are strong evidence that the tens of billions that Californians have spent on renewables come with high human, economic, and environmental costs.

Last December, a report by done for PG&E concluded that the utility’s customers could see blackouts double over the next 15 years and quadruple over the next 30.

California’s anti-nuclear policies also contributed to the blackouts. In 2013, Gov. Jerry Brown forced a nuclear power plant, San Onofre, in southern California to close.

Had San Onofre still been operating, there almost certainly would not have been blackouts on Friday as the reserve margin would have been significantly larger. The capacity of San Onofre was double that of the lost generation capacity that triggered the blackout.

California's current and former large nuclear plants are located on the coast, which allows for their electricity to travel shorter distances, and through less-constrained transmission lines than the state’s industrial solar farms, to get to the coastal cities where electricity is in highest demand.

There has been very little electricity from wind during the summer heatwave in California and the broader western U.S., further driving up demand. In fact, the same weather pattern, a stable high-pressure bubble, is the cause of heatwaves, since it brought very low wind for days on end along with very high temperatures.

Things won’t be any better, and may be worse, in the winter, with a looming shortage as it produces far less solar electricity than the summer. Solar plus storage, an expensive attempt to fix problems like what led to this blackout, cannot help through long winters of low output.

California’s electricity prices will continue to rise if it continues to add more renewables to its grid, and goes forward with plans to shut down its last nuclear plant, Diablo Canyon, in 2025.

Had California spent an estimated $100 billion on nuclear instead of on wind and solar, it would have had enough energy to replace all fossil fuels in its in-state electricity mix.

To manage the increasingly unreliable grid, California will either need to keep its nuclear plant operating, build more natural gas plants, underscoring its reliance on fossil fuels for reliability, or pay ever more money annually to reserve emergency electricity supplies from its neighbors.

After the blackouts last October, Gov. Newsom attacked PG&E Corp. for “greed and mismanagement” and named a top aide, Ana Matosantos, to be his “energy czar.” 

“This is not the new normal, and this does not take 10 years to solve,” Newsom said. “The entire system needs to be reimagined.”
