Strengthening interprovincial electrical ties

Press Release

Mar 06, 2026

Alberta joins numerous provinces across Canada in an interprovincial-territorial agreement to strengthen grid reliability and energy security.

Alberta’s government has signed onto a first-of-its-kind Partnership Agreement on Transmission Interties aimed at building a national energy corridor. This agreement establishes a collaborative framework to break down barriers between provincial and territorial power grids by exploring opportunities to modernize electricity transmission and secure a more resilient energy future.

As electricity demand grows due to population increases, industrial expansion and electrification, stronger interprovincial connections can help improve system flexibility, reduce risk during periods of peak demand and support investment across Canada’s electricity sector. At the same time, it will ensure each province, including Alberta, will maintain authority over its respective systems.

“Alberta is proud to join this partnership. With one of the country’s most reliable power grids, we are well positioned to be a key pillar in strengthening connections with our neighbours to build the strong, stable energy foundation that Canada needs to stay competitive and drive long-term prosperity for all Canadians.”

Nathan Neudorf, Minister of Affordability and Utilities

“This first-of-its-kind partnership lays the foundation for thousands of jobs, billions in investment, and a modernized grid that advances Canada’s long-term energy future. Together, we are advancing Made-in-Canada energy solutions to meet unprecedented energy demand and keep Canada’s economy strong.”

Stephen Lecce, Ontario Minister of Energy and Mines

Through this partnership, provinces and territories have agreed to work together to advance and expand opportunities for mutually beneficial electricity trade within Canada, including potential intertie projects. This includes improved planning and information sharing between provinces and territories, as well as advocating for federal support to reduce regulatory barriers and advance transmission projects. The partnership also acknowledges Indigenous communities as meaningful partners in electricity development and supports engagement and participation opportunities.

“Alberta’s electricity grid is undergoing rapid change. Interties are an essential part of the power system, supporting reliability and enabling energy trade. The AESO welcomes enhanced interprovincial cooperation to create value for Albertans and our neighbouring provinces through these interconnections.”

Aaron Engen, CEO, Alberta Electric System Operator (AESO)

The agreement will see Alberta join B.C., Saskatchewan, Manitoba, Ontario, New Brunswick, Nova Scotia, P.E.I., Yukon and the Northwest Territories at least twice a year to advance collaborative work. The agreement has an initial term of eight years, with an option to renew.

Quick facts

• Electrical interconnections – known as interties – support system resilience, improve access to electricity trade and enhance reliability during peak demand or emergency events.
• Alberta has three interties with neighbouring jurisdictions, including the Alberta-B.C. Intertie, Alberta-Saskatchewan Intertie, and the privately-owned Montana Alberta Tie Line.
• Alberta became a net exporter of electricity in 2024.
• In 2025, Alberta averaged an export of 348 MWh on the B.C. and Montana interties.
