“We will not risk plunging our homes, schools, hospitals, special care homes and our businesses into the cold and darkness because of the ideological whims of others.”

Alberta’s close brush with possible rolling blackouts stiffens Moe’s resolve to keep the lights on.

Moe reiterates: “We will not attempt the impossible when it comes to power production”

The past weekend proved to be a close-run thing for the Alberta electrical grid, and Saskatchewan Premier Scott Moe is making statements resolving he won’t allow that to happen here.

Specifically, after having nearly completely divested itself of coal-fired power production, Alberta’s dramatic buildout of wind and solar proved impossible to keep the lights on in that province when the chips were down and temperatures hit -35 C, or worse.

“In Saskatchewan, we will not attempt the impossible when it comes to power production in our province,” Moe said in a post on X and other social media the evening of Monday, Jan. 15.

“We will not risk plunging our homes, schools, hospitals, special care homes and our businesses into the cold and darkness because of the ideological whims of others.

“To support the ongoing power demands across western Canada, Boundary Dam 4 has been restarted to ensure families can continue to keep the heat on. Net zero by 2035 is not only impossible, it’s irresponsible as it would leave Saskatchewan and Western Canadian families freezing and in the dark.”

It was in response to the extraordinary events that occurred in Alberta over the weekend, in which Saskatchewan played a key part. And it was also a tacit acknowledgement that as much as SaskPower’s been trying to wean itself off coal, it just can’t do it yet. We still need it to keep the lights on.

The Alberta Electric System Operator (AESO) declared four “grid alerts,” over four days in a row, starting the afternoon of Friday, Jan. 12. Desperately cold temperatures drove up demand for power, just as the same temperatures reduced wind power generation to nothing at times, and close to nothing for most of the weekend. And since the mass of cold air stretched from the Yukon to Texas, every grid operator in between was in the same boat – high demand but short supply. The Southwest Power Pool, which incorporates parts of 14 states from south of Saskatchewan to the Texas Panhandle, as well as Texas grid operator ERCOT, all put out various forms of alerts suggesting their clients reduce electrical consumption.

Staring into the abyss

The first three of Alberta’s grid alerts ran from mid-afternoon until late evening, but the fourth occurred for an hour on Monday morning, as the workweek began.

The second of those grid alerts turned out to be the most significant. On Saturday, Jan. 13, Alberta came within a half-hour of rotating blackouts, an Alberta Electric System Operator spokesperson told CBC News on Jan. 15, confirmed by Alberta Affordability and Utilities Minister Nathan Neudorf the same day.

Indeed, the province stood at the brink of the abyss Saturday night, as rotating blackouts would have impacted different areas of the province for 20 to 30 minutes at a time, as temperatures ranged from -30 to -45 C, depending on where you were in the province. As the province’s grid-scale batteries neared depletion, and there was nothing left to call upon, the AESO and provincial government put out an emergency alert to all cellphones and TV screens, asking Albertans to shut off and unplug everything they could, from electric vehicle chargers to ovens to bathroom fans.

SaskPower ups its game

Alberta had run out of reserves, and with British Columbia unable to provide much more in the way of additional power, and Montana unable provide much at all, Saskatchewan’s Crown utility SaskPower responded, by sending 153 megawatts westward.

And that, in itself, was extraordinary, because limits were pushed to provide Alberta with as much as possible on the intertie between the two provinces.

SaskPower spokesperson Joel Cherry told Pipeline Online by email, “One hundred fifty-three megawatts is the interconnection’s maximum capacity, but it has been derated to 90 megawatts for the past several months because of ongoing work at a interconnection station at the border. AESO and SaskPower Grid Control have agreed to temporarily increase the transmission capacity to make the extra 63 MW available to Alberta when they declare energy alerts.

Contingency reserve had run out

Generally speaking, power needs to be consumed at the instant its produced. There is very little in the way of grid-scale storage in the Canadian electrical grid, although Alberta has built 10 grid-scale batteries totaling 190 megawatts capacity. All of that capacity would come into play Saturday evening.

Grid operators must maintain a small amount of excess capacity at all times, known as a “dispatched contingency reserve” (DCR) The North American Electric Reliability Corporation (NERC) standard is to maintain at least 4 per cent DCR. That’s because if the DCR runs out, all sorts of bad things happen, with voltage drops and frequency variance which then can lead to cascading brownouts, including additional power generating units tripping off and whole areas going without power.

With demand hovering around 11,800 megawatts, four per cent would have been around 472 megawatts DRC. Instead, for the better part of an hour, the DCR was 20 megawatts, or 0.1 per cent, a razor thin margin. The extra 63 megawatts SaskPower sent in part meant the difference between rotating blackouts or not.

In a very real way, it was payback for Alberta’s weeks-long help for SaskPower during the outage of the Poplar River Power Station at Coronach, Saskatchewan. For weeks on end, Alberta supplied Saskatchewan with around 150 megawatts for parts of the day to keep the lights on in this province.

BC played critical role, too

On any given day, imports and exports of power between Alberta and British Columbia will often run up to 600 megawatts going either direction. But with BC also in the deep freeze, it didn’t have much to give at various points during the weekend, including parts of the crucial Saturday evening. Indeed, around the time the grid alert was first sounded on Saturday, Alberta was still exporting 38 megawatts to British Columbia, according to X bot account @ReliableAB, which posts hourly data from the AESO on the status of the Alberta grid.

For a few hours, BC Hydro was able to ramp up its exports to Alberta during the crucial time. At 5:39, they were exporting 251 megawatts to Alberta, nearly 100 megawatts more than Saskatchewan. For the next few hours they sent around 200 megawatts, but it was not enough, and the AESO sent out its alert.

Additionally, during the third grid alert on Sunday, British Columbia ramping up its power exports at a critical time saved the day, as the Alberta Dispatched Contingency Reserve had briefly hit zero. BC bumped its exports up to 496 megawatts while Saskatchewan contributed 153 and Montana nine. Those increased megawatts from British Columbia appeared to make all the difference on that day.

The cat came back, and so did Unit 4

While all of this was going on, SaskPower spent the weekend getting its coal fired power station Boundary Dam Unit 4 back into play. It’s been on cold standby for months. Officially, by federal regulations it was supposed to retire Dec. 31, 2021, but SaskPower has been forced to bring it back into service multiple times to fill a need, such as when Poplar River went offline last June. It was 139 megawatts that could have been used, but SaskPower has shown reluctance to bring it back into the game, as it were.

And that’s what Moe alluded to in his social media post, saying, “We will not risk plunging our homes, schools, hospitals, special care homes and our businesses into the cold and darkness because of the ideological whims of others.”

This was an oblique reference to the push by the federal government to shut down coal and natural gas-fired power generation by 2035, according to the proposed Clean Electricity Regulations, using similar words that Moe has expressed before. The federal preference is for more renewables, in particular wind and solar.

Several years ago, the federal government and Saskatchewan reached an equivalency agreement, recognizing the Boundary Dam Unit 3 Carbon Capture and Storage Project and therefore allowing a few more years operation out of other coal units. But to get that agreement, SaskPower had to agree to adding a further 3,000 megawatts of wind and solar by 2035, according to SaskPower president and CEO Rupen Pandya in an interview Sept. 25, 2023.

Pandya said, “When we signed the equivalency agreement with the federal government in 2014 to allow us to keep using coal to the end of 2030, part of that agreement required us to build out renewables in the province, so that we could operate coal assets, coal generators, past their end of life. And that’s what we’ve been able to do. And we continue to do. So, part of the build out of renewables that’s required as part of the equivalency agreement, that 3,000 megawatts that we need to put in place by 2035. I think 2,000 by 2030. A good tranche of that will be in that south central part of Saskatchewan around the Coronach. So we currently have in the market an RFP for 700 megawatts of wind and solar in the Coronach region, so it’ll will actually go into power, if all goes well with RFPs, in 2027.”

On a typical fall day, SaskPower’s total power demand hovers around 3,000 megawatts. On a cold winter day, it’s closer to 3,500 megawatts. But that’s before widespread adoption of electric vehicles, which the federal government is also trying to force upon Canadians.

Saskatchewan held up to the cold

SaskPower’s Joel Cherry told Pipeline Online on Jan. 15, “Saskatchewan’s system has held up during the extreme cold. We had no major issues.”

However, “Poplar River Power Station was operating at reduced capacity earlier in the weekend because of issues with coal supply. As of yesterday (Sunday) we are back to normal operations there.”

That means the reduced capacity occurred the same day Alberta was stretched nearly to the breaking point.

Asked if we lost a major unit, while Alberta was at the same time in crisis, what did we have for backup? Was there additional capacity available from Manitoba and/or Southwest Power Pool?” Cherry replied, “SaskPower has maintained adequate reserves to allow for the continued stability of the system even if we lost a large unit. We have also been importing from Manitoba and the SPP when available.

Collapse of wind

Major factors in Alberta’s power woes were the utter collapse of wind and solar power generation. Even at its best, solar power production during the day was around a third of maximum capacity.

Wind turbines started shutting down Thursday night as temperatures plummeted below -30 C, the temperature where cold brittle behaviour of materials risks catastrophic failure of the turbines. The three evening grid alerts all came on as the sun went down and the roughly 500 megawatts (of 1,650 megawatts capacity) faded with the setting sun. On Friday, Alberta’s wind generation fell to 6 megawatts at one point. It was minimal on Saturday. On Sunday morning, multiple times wind hit zero – not one megawatt from the 4,481 megawatts of wind generation capacity.

SaskPower’s Where Your Power Comes From webpage noted on Friday, Jan. 14, Saskatchewan’s 617 megawatts of grid-scale wind produced a 24-hour average of 21 megawatts. On Saturday, that number was 19. On Sunday, the average was 22 megawatts. Unlike the previous week, where there were seven days where wind in Saskatchewan hit zero power output, Jan. 12-14 did not have any periods of zero.

“We had four hours of less than 10 megawatts wind output on Jan 12, despite the low average through the day on Jan. 13 we only had a half hour below 10 megawatts and on Jan 14 we had 7.8 hours below 10 megawatts,” Cherry said.

Ten megawatts is 1.6 per cent of total grid-scale wind capacity in Saskatchewan.

As for Unit 4, in April of 2023, Pipeline Online reported Cherry said at the time, “We’re going to keep BD 4 in laid up status until Great Plains Power Station comes online, or until March 31, 2024.”

The most recent plan, as of April, 2023, was to shut down, for good, Unit 4 by March 31, 2023. Whether Moe’s statement on Jan. 15 will extend that is unknown at the time of writing.

Here’s why city hall should save ‘blanket rezoning’ in Calgary

Published on

From the Fraser Institute

By Tegan Hill and Austin Thompson

According to Calgarians for Thoughtful Growth (CFTG)—an organization advocating against “blanket rezoning”— housing would be more affordable if the mayor and council restricted what homes can be built in Calgary and where. But that gets the economics backwards.

Blanket rezoning—a 2024 policy that allowed homebuilders to construct duplexes, townhomes and fourplexes in most neighbourhoods—allowed more homebuilding, giving Calgarians more choice, and put downward pressure on prices. Mayor Farkas and several councillors campaigned on repealing blanket rezoning and on December 15 council will debate a motion that could start that process. As Calgarians debate the city’s housing rules, residents should understand the trade-offs involved.

When CFTG claims that blanket rezoning does “nothing” for affordability, it ignores a large body of economic research showing the opposite.

New homes are only built when they can be sold to willing homebuyers for a profit. Restrictions that limit the range of styles and locations for new homes, or that lock denser housing behind a long, costly and uncertain municipal approval process, inevitably eliminate many of these opportunities. That means fewer new homes are built, which worsens housing scarcity and pushes up prices. This intuitive story is backed up by study after study. An analysis by Canada’s federal housing agency put it simply: “higher residential land use regulation seems to be associated with lower housing affordability.”

CFTG also claims that blanket rezoning merely encourages “speculation” (i.e. buying to sell in the short-term for profit) by investors. Any profitable housing market may invite some speculative activity. But homebuilders and investors can only survive financially if they make homes that families are willing to buy or rent. The many Calgary families who bought or rented a new home enabled by blanket rezoning did so because they felt it was their best available option given its price, amenities and location—not because they were pawns in some speculative game. Calgarians benefit when they are free to choose the type of home and neighbourhood that best suits their family, rather than being constrained by the political whims of city hall.

And CFTG’s claim that blanket rezoning harms municipal finances also warrants scrutiny. More specifically, CFTG suggests that developers do not pay for infrastructure upgrades in established neighbourhoods, but this is simply incorrect. The City of Calgary charges an “Established Area Levy” to cover the cost of water and wastewater upgrades spurred by redevelopment projects—raising $16.5 million in 2024 alone. Builders in the downtown area must pay the “Centre City Levy,” which funds several local services (and generated $2.5 million in 2024).

It’s true that municipal fees on homes in new communities are generally higher, but that reflects the reality that new communities require far more new pipes, roads and facilities than established neighbourhoods.

Redeveloping established areas of the city means more residents can make use of streets, transit and other city services already in place, which is often the most cost-effective way for a city to grow. The City of Calgary’s own analysis finds that redevelopment in established neighbourhoods saves billions of taxpayer dollars on capital and operating costs for city services compared to an alternative scenario where homebuilding is concentrated in new suburban communities.

An honest debate about blanket rezoning ought to acknowledge the advantages this system has in promoting housing choice, housing affordability and the sustainability of municipal finances.

Clearly, many Calgarians felt blanket rezoning was undesirable when they voted for mayoral and council candidates who promised to change Calgary’s zoning rules. However, Calgarians also voted for a mayor who promised that more homes would be built faster, and at affordable prices—something that will be harder to achieve if city hall imposes tighter restrictions on where and what types of homes can be built. This unavoidable tension should be at the heart of the debate.

CFTG is promoting a comforting fairy tale where Calgary can tighten restrictions on homebuilding without limiting supply or driving up prices. In reality, no zoning regime delivers everything at once—greater neighbourhood control inevitably comes at the expense of housing choice and affordability. Calgarians—including the mayor and council—need a clear understanding of the trade-offs.

The case for expanding Canada’s energy exports

Published on

From the Canadian Energy Centre

By Deborah Jaremko

For Canada, the path to a stronger economy — and stronger global influence — runs through energy.

That’s the view of David Detomasi, a professor at the Smith School of Business at Queen’s University.

Detomasi, author of Profits and Power: Navigating the Politics and Geopolitics of Oil, argues that there is a moral case for developing Canada’s energy, both for Canadians and the world.

CEC: What does being an energy superpower mean to you?

DD: It means Canada is strong enough to affect the system as a whole by its choices.

There is something really valuable about Canada’s — and Alberta’s — way of producing carbon energy that goes beyond just the monetary rewards.

CEC: You talk about the moral case for developing Canada’s energy. What do you mean? 

DD: I think the default assumption in public rhetoric is that the environmental movement is the only voice speaking for the moral betterment of the world. That needs to be challenged.

That public rhetoric is that the act of cultivating a powerful, effective economic engine is somehow wrong or bad, and that efforts to create wealth are somehow morally tainted.

I think that’s dead wrong. Economic growth is morally good, and we should foster it.

Economic growth generates money, and you can’t do anything you want to do in social expenditures without that engine.

Economic growth is critical to doing all the other things we want to do as Canadians, like having a publicly funded health care system or providing transfer payments to less well-off provinces.

Over the last 10 years, many people in Canada came to equate moral leadership with getting off of oil and gas as quickly as possible. I think that is a mistake, and far too narrow.

Instead, I think moral leadership means you play that game, you play it well, and you do it in our interest, in the Canadian way.

We need a solid base of economic prosperity in this country first, and then we can help others.

CEC: Why is it important to expand Canada’s energy trade?

DD: Canada is, and has always been, a trading nation, because we’ve got a lot of geography and not that many people.

If we don’t trade what we have with the outside world, we aren’t going to be able to develop economically, because we don’t have the internal size and capacity.

Historically, most of that trade has been with the United States. Geography and history mean it will always be our primary trade partner.

But the United States clearly can be an unreliable partner. Free and open trade matters more to Canada than it does to the U.S. Indeed, a big chunk of the American people is skeptical of participating in a global trading system.

As the United States perhaps withdraws from the international trading and investment system, there’s room for Canada to reinforce it in places where we can use our resource advantages to build new, stronger relationships.

One of these is Europe, which still imports a lot of gas. We can also build positive relationships with the enormous emerging markets of China and India, both of whom want and will need enormous supplies of energy for many decades.

I would like to be able to offer partners the alternative option of buying Canadian energy so that they are less reliant on, say, Iranian or Russian energy.

Canada can also maybe eventually help the two billion people in the world currently without energy access.

CEC: What benefits could Canadians gain by becoming an energy superpower? 

DD: The first and primary responsibility of our federal government is to look after Canada. At the end of the day, the goal is to improve Canada’s welfare and enhance its sovereignty.

More carbon energy development helps Canada. We have massive debt, an investment crisis and productivity problems that we’ve been talking about forever. Economic and job growth are weak.

Solving these will require profitable and productive industries. We don’t have so many economic strengths in this country that we can voluntarily ignore or constrain one of our biggest industries.

The economic benefits pay for things that make you stronger as a country.

They make you more resilient on the social welfare front and make increasing defence expenditures, which we sorely need, more affordable. It allows us to manage the debt that we’re running up, and supports deals for Canada’s Indigenous peoples.

CEC: Are there specific projects that you advocate for to make Canada an energy superpower?

DD: Canada’s energy needs egress, and getting it out to places other than the United States. That means more transport and port facilities to Canada’s coasts.

We also need domestic energy transport networks. People don’t know this, but a big chunk of Ontario’s oil supply runs through Michigan, posing a latent security risk to Ontario’s energy security.

We need to change the perception that pipelines are evil. There’s a spiderweb of them across the globe, and more are being built.

Building pipelines here, with Canadian technology and know-how, builds our competitiveness and enhances our sovereignty.

Economic growth enhances sovereignty and provides the resources to do other things. We should applaud and encourage it, and the carbon energy sector can lead the way.
