When natural gas power plant outages brought Alberta’s electricity grid to the , one key factor kept the lights on. That crucial backstop? Imports of electricity from 小蓝视频 and other areas, through what are known as interties.
Yet despite the role imported power plays as a source of reliability and insurance, Alberta has neglected those lines, much to the consternation of provincial and state neighbours.
Through a freedom of information request, The Narwhal obtained a letter B.C’s former energy minister last July to Alberta’s minister of affordability and utilities, Nathan Neudorf. In the letter, then-B.C energy minister Josie Osborne urged Alberta to prioritize upgrades on the electricity link between the two provinces — something it has been obligated to do under its own since 2007.
As Alberta embarks on a massive overhaul of its electricity market, the letter revealed 小蓝视频 was growing concerned power imports were being overlooked. Osborne cited short-term solutions she said likely wouldn’t have a significant impact on the intertie’s capacity and past promises from the Alberta Electric System Operator — the independent agency that operates Alberta’s grid — to improve the link that went unfulfilled.
“Given this context, 小蓝视频 is becoming increasingly concerned that intertie restoration efforts may have ceased to be a priority,” Osborne wrote.
The former minister argued Alberta was restricting imports of electricity, in violation of interprovincial agreements and to the financial detriment of 小蓝视频
A ministerial briefing note written at the same time as Osborne’s letter said Alberta was restricting commercial imports of electricity on the line and then relying on the intertie in times of emergency to draw power from 小蓝视频 and other jurisdictions — without due compensation.
“The choice to significantly de-rate the intertie’s commercial capacity from 小蓝视频 to Alberta, a choice taken despite the availability of other options and instead of making restorative investments, undermines the intended mutual benefit by creating asymmetric market access for Alberta supply,” Osborne wrote to Neudorf.
Since then, to initiate work on the intertie, but it remains unclear whether that work will satisfy its neighbour to the west.
A written after Neudorf’s direction stated, “There is no mechanism currently in place to ensure the 小蓝视频-Alberta intertie is being utilized most effectively for the benefit of both parties.”
Owner of Montana power line also raises concerns about Alberta restricting electricity imports
Interties can be a critical component of a , pulling hydro power from 小蓝视频 when required, or sending renewables and natural gas from Alberta west. The more connections there are, the more stable the system is.
Interties can also contribute to competition in Alberta’s private electricity market and bring down prices — a goal of the government and a concern for the province’s big power generators.
Suncor, which is now one of the largest generators in Alberta, has with the Alberta Utilities Commission to add an additional charge to electricity imports.
Alberta is currently the least interconnected province in the country, , which argues the lack of reliable interties impacts prices, competition and the ability to sell exports, as well as emissions reductions targets.
The 小蓝视频 intertie is supposed to allow 950 megawatts of imports — approximately five per cent of — but requires infrastructure upgrades to achieve that level.
Jason Wang, an electricity analyst with the Pembina Institute, noted Alberta is able to export more electricity to 小蓝视频 than it can import from 小蓝视频
The line is also intentionally restricted by the Alberta Electric System Operator so that it can respond quickly to issues with the Alberta grid.
Wang, with the Pembina Institute, described the 小蓝视频-Alberta intertie as a four-lane highway with all the space that’s needed for traffic to flow, but littered with potholes on the Alberta side. Once you cross the border, everything slows down.
Fixing those “potholes” on Alberta’s side of the intertie requires infrastructure such as substations and batteries that can quickly respond to fluctuations on the grid, which Wang said will require significant investments.
To the south, Berkshire Hathaway Energy — the private company which owns the Montana intertie — argues Alberta is also restricting imports on the intertie it operates between Montana and Alberta and has with the Alberta Utilities Commission.
Berkshire Hathaway spokesperson Scott Schreiner declined to comment for this story.
“Stakeholders in Alberta’s electricity market, including ourselves, are currently participating in consultations on market design and policies, so we have no comment at this time,” he wrote.
Part of those market reforms aim to address how imports of electricity are treated in Alberta’s private system and how the prices are determined, but those details haven’t been finalized.
‘Look forward to a positive resolution’
On Wednesday, 小蓝视频 Energy and Climate Solutions Minister Adrian Dix told The Narwhal he’s having regular conversations with Alberta, including a meeting this week with Neudorf.
Dix wouldn’t say whether he believes the changes on the table in Alberta will be enough to satisfy his government, but insisted the two jurisdictions are trying to find a solution as Alberta reforms its market.
“We’re working closely with the Alberta government and look forward to a positive resolution for both our provinces one of these days,” Dix said, adding 小蓝视频’s concern is about who benefits from the market reforms being discussed in Alberta.
The Alberta Electric System Operator responded to a request for an interview by pointing to a letter from Neudorf outlining the need to work on the 小蓝视频 intertie, as well as interties with Montana and Saskatchewan. It also directed The Narwhal to its recently released “Long-Term Transmission Plan.”
Both documents call for a “needs identification document” for the restoration of the intertie — essentially a justification for a project — to be submitted by the end of 2026.
Ashli Barrett, the spokesperson for Neudorf, said Alberta is updating transmission policies and “reducing red tape” to improve interties.
“We intend to bring forward legislation this spring to support these changes as part of the government’s efforts to ensure Albertans have reliable and affordable power now and for generations to come,” Barrett said by email. “When fully implemented, these changes will restore the Alberta-小蓝视频 intertie to 950 megawatts.”
‘There might be consequences for 小蓝视频’: 小蓝视频 energy minister
The grid operator’s long-term plan calls for a three-step approach to improve interties, ultimately leading to an increased ability to import power.
A longer-term plan calls for investigation into a second line connecting Alberta and 小蓝视频
In its presentation last year, 小蓝视频 Hydro said some proposed reforms could increase costs for 小蓝视频 ratepayers. It said a negotiated agreement with Alberta would be the preferred route, but didn’t rule out taking other, unspecified measures if that fails.
“There might be consequences for 小蓝视频 and there are consequences that we could respond to,” Dix told The Narwhal. “But rather than responding to that in that way — I think especially in these times — we’ve got to take every step to work together to have mutually beneficial arrangements.”
