Alberta’s emergency grid alert underscores vital role diverse energy mix plays in Canada

After a major cold spell affected the capacity of Alberta’s power grid to provide electricity, experts weigh in on the need for multiple sources of energy
The crucial need for Canada to have a flexible and diverse energy grid was given a practical demonstration this past weekend as frigid winter temperatures in Alberta prompted a grid emergency.
With temperatures in some places dropping to almost –50C with the wind chill, provincial officials issued an emergency alert asking Albertans to immediately reduce electricity usage, with the grid approaching maximum capacity during peak hours.
With wind and solar assets unable to contribute power and the unexpected shutdown of two natural gas plants, Albertans faced the possibility of rolling blackouts in dangerously cold conditions.
A day after the emergency, the Alberta Electric System Operator (AESO) thanked Albertans who responded quickly to reduce the demand load.
“This is an example of why we need to ensure that we have sufficient dispatchable, dependable generation available to us as a province to meet what is always our most challenging time, which is those cold, dark winter nights,” Michael Law, CEO of AESO, told the Calgary Herald.
The prospect of failure in the worst possible circumstances prompted energy analysts to highlight the critical need for a diverse and flexible energy grid.
“You could have had 50,000 megawatts, all the solar farms and wind farms in the world located in Alberta, and it still wouldn’t have come anywhere close to closing that gap,” University of Alberta economics professor Andrew Leach told CBC News.
Wind and solar can be major contributors to the grid when conditions allow, but when the sun goes down and the wind stops, base load power sources like natural gas reliably protect the system.
Leach said system operators need to plan for supply to manage adverse weather conditions to ensure the reliability of the grid.
“Whether it’s natural gas, nuclear, import capacity, battery storage, etc., geothermal, there’s nobody that’s arguing against that.”
With policymakers pushing for more electrification, University of Alberta industrial engineering professor Tim Weis said Alberta isn’t alone in the need for resilient and stable power supply.
“I think we need to wrestle with that and realize that we are moving into a world where there’s going to be more electrical demands on the system,” he told Global News.
“We are moving into a new world. We’re not the only ones facing some of these challenges. I think we’re a little bit behind responding in terms of dispatchable demand and allowing consumers the opportunity to automatically respond to some of these things.”
As the federal government aims to decarbonize Canada’s electricity generation by 2035 with sweeping regulations, flexibility for some jurisdictions is a key factor that needs to be addressed, said University of Calgary associate professor of economics Blake Shaffer.
“I do think that this shows us that no amount of renewables would push us to have solved that winter peak on Saturday,” he told CTV Calgary.
“And that means flexibility to have a gas fleet, for example, that is capable of being there for a few hours for a few days, maybe a few weeks a year. And we need the technical and economic setup to make that worth their while to be there,” Shaffer said.
“We saw this cold weather coming, everybody was preparing for it. The wind forecast was out a week ago we saw there was going to be no wind. Thankfully, the gas thermal fleet performed amazingly well.”
Natural gas generation was able to backstop the reduction in renewable power, said ARC Energy Research Institute executive director Jackie Forrest.
“The system delivered during the deep freeze this past weekend… so reliably that no one even noticed… I have long argued that gaseous fuels are needed in the mix for energy transition and the need to become cleaner; this is why,” said Forrest on X, formerly known as Twitter.
According to Forrest’s colleague, energy economist Peter Tertzakian, Alberta’s oil sands industry also plays a big role in power generation in the province with the prominence of natural gas-powered cogeneration facilities.
“The power that’s generated in this province during this cold spell, about 40 per cent of it comes from cogeneration. The bulk of which comes from the oil sands and all their big generators which have surplus electricity that they feed into the grid,” said Tertzakian on ARC Energy Institute’s latest podcast.
“I think it’s important to understand that any policies that affect oil sands also affect the electricity grid.”

Alberta court upholds conviction of Pastor Artur Pawlowski for preaching at Freedom Convoy protest
From LifeSiteNews
Lawyers argued that Pastor Artur Pawlowski’s sermon was intended to encourage protesters to find a peaceful solution to the blockade, but the statement was characterized as a call for mischief.
An Alberta Court of Appeal ruled that Calgary Pastor Artur Pawlowski is guilty of mischief for his sermon at the Freedom Convoy-related border protest blockade in February 2022 in Coutts, Alberta.
On October 29, Alberta Court of Appeal Justice Gordon Krinke sentenced the pro-freedom pastor to 60 days in jail for “counselling mischief” by encouraging protesters to continue blocking Highway 4 to protest COVID mandates.
“A reasonable person would understand the appellant’s speech to be an active inducement of the illegal activity that was ongoing and that the appellant intended for his speech to be so understood,” the decision reads.
Pawlowski addressed a group of truckers and protesters blocking entrance into the U.S. state of Montana on February 3, the fifth day of the Freedom Convoy-styled protest. He encouraged the protesters to “hold the line” after they had reportedly made a deal with Royal Canadian Mounted Police to leave the border crossing and travel to Edmonton.
“The eyes of the world are fixed right here on you guys. You are the heroes,” Pawlowski said. “Don’t you dare go breaking the line.”
After Pawlowski’s sermon, the protesters remained at the border crossing for two additional weeks. While his lawyers argued that his speech was made to encourage protesters to find a peaceful solution to the blockade, the statement is being characterized as a call for mischief.
Days later, on February 8, Pawlowski was arrested – for the fifth time – by an undercover SWAT team just before he was slated to speak again to the Coutts protesters.
He was subsequently jailed for nearly three months for what he said was for speaking out against COVID mandates, the subject of all the Freedom Convoy-related protests.
In Krinke’s decision, he argued that Pawlowski’s sermon incited the continuation of the protest, saying, “The Charter does not provide justification to anybody who incites a third party to commit such crimes.”
However, defence lawyer Sarah Miller pointed out that that Pawlowski’s sermon was protected under freedom of speech, an argument that Krinke quickly dismissed.
“While the appellant is correct that peaceful, lawful and nonviolent communication is entitled to protection, blockading a highway is an inherently aggressive and potentially violent form of conduct, designed to intimidate and impede the movement of third parties,” he wrote.
Pawlowski was released after the verdict. He has already spent 78 days in jail before the trial.
Pawlowski is the first Albertan to be charged for violating the province’s Critical Infrastructure Defence Act (CIDA), which was put in place in 2020 under then-Premier Jason Kenney.
The CIDA, however, was not put in place due to COVID mandates but rather after anti-pipeline protesters blockaded key infrastructure points such as railway lines in Alberta a few years ago.

New compressed natural gas fueling stations in Grande Prairie and Calgary join new stop in Edmonton
Heavy-duty truckers hauling everything from restaurant supplies to specialized oilfield services along one of Western Canada’s busiest corridors now have more access to a fuel that can help reduce emissions and save costs.
Two new fuelling stations serving compressed natural gas (CNG) rather than diesel in Grande Prairie and Calgary, along with a stop that opened in Edmonton last year, create the first phase of what proponents call a “natural gas highway”.
“Compressed natural gas is viable, it’s competitive and it’s good for the environment,” said Murray Mullen, chair of Mullen Group, which operates more than 4,300 trucks and thousands of pieces of equipment supporting Western Canada’s energy industry.
Right now, the company is running 19 CNG units and plans to deploy another 15 as they become available.
“They’re running the highways right now and they’re performing exceptionally well,” Mullen said on Oct. 22 during the ribbon-cutting ceremony opening the new station on the northern edge of Calgary along Highway 2.
“Our people love them, our customers love them and I think it’s going to be the way for the future to be honest,” he said.

According to Natural Resources Canada, natural gas burns more cleanly than gasoline or diesel fuel, producing fewer toxic pollutants and greenhouse gas emissions that contribute to climate change.
The two new CNG stops are part of a $70 million partnership announced last year between major Canadian natural gas producer Tourmaline and California-based Clean Energy Fuels.
Their deal would see up to 20 new CNG stations built in Western Canada over the next five years, daily filling up to 3,000 natural gas-fueled trucks.
One of North America’s biggest trucking suppliers to businesses including McDonald’s, Pizza Hut, Subway and Popeye’s says the new stations will help as it expands its fleet of CNG-powered vehicles across Canada.
Amy Senter, global vice-president of sustainability with Illinois-based Martin Brower, said in a statement that using more CNG is critical to the company achieving its emissions reduction targets.
For Tourmaline, delivering CNG to heavy-duty truckers builds on its multi-year program to displace diesel in its operations, primarily by switching drilling equipment to run on natural gas.
Between 2018 and 2022, the company displaced the equivalent of 36 Olympic-sized swimming pools worth of diesel that didn’t get used, or the equivalent emissions of about 58,000 passenger vehicles.

Tourmaline CEO Mike Rose noted that the trucking sector switching fuel from diesel to natural gas is gaining momentum, notably in Asia.
A “small but growing” share of China’s trucking fleet moving to natural gas helped drive an 11 percent reduction in overall diesel consumption this June compared to the previous year, according to the latest data from the U.S. Energy Information Administration.
“China’s talking about 30 percent of the trucks sold going forward are to be CNG trucks, and it’s all about reducing emissions,” Rose said.
“It’s one global atmosphere. We’re going to reduce them here; they’re going to reduce them there and everybody’s a net winner.”
Switching from diesel to CNG is “extremely cost competitive” for trucking fleets, said Clean Energy CEO Andrew Littlefair.
“It will really move the big rigs that we need in Western Canada for the long distance and heavy loads,” he said.
Tourmaline and Clean Energy aim to have seven CNG fuelling stations operating by the end of 2025. Construction is set to begin in Kamloops, B.C., followed by Fort McMurray and Fort St. John.
“You’ll have that Western Canadian corridor, and then we’ll grow it from there,” Littlefair said.
