Canada and British Columbia break ground on $3.9-billion North Coast Transmission Line to expand clean power capacity

Canada and British Columbia broke ground Thursday, September 3, 2026, on Phase 1 of the North Coast Transmission Line — a 103-mile, 500-kilovolt segment running from the Williston Substation near Prince George to the Glenannan Substation near Fraser Lake. Federal and provincial governments, BC Hydro, and Indigenous partners marked the milestone with $3.9 billion in combined funding committed under the Canada–British Columbia Cooperative Prosperity Agreement.

The project is designed to more than double clean electricity availability along B.C.’s West Coast. What that capacity is meant to unlock, though, goes well beyond the power grid.

Groundbreaking marks start of Phase 1 construction

Canada and British Columbia broke ground Thursday, September 3, 2026, on Phase 1 of the North Coast Transmission Line — a 103-mile, 500-kilovolt segment running from the Williston Substation near Prince George to the Glenannan Substation near Fraser Lake. Federal and provincial governments, BC Hydro, and Indigenous partners marked the milestone along a 500-kilovolt corridor, connecting two substations in B.C.’s north-central interior. It expands an existing transmission line already running from Prince George to Terrace — pushing the grid deeper into a region that’s faced electricity constraints for decades.

On November 13, 2025, the NCTL was referred to the Major Projects Office, a federal mechanism designed to accelerate regulatory coordination across departments.

Thursday’s ceremony drew federal and provincial ministers, BC Hydro officials, and Indigenous leaders. Among them was Lheidli T’enneh First Nation Chief Dolleen Logan, who called the groundbreaking “a new beginning for our region.” Her presence highlighted one of the project’s defining features: First Nations have the opportunity to co-own up to 50 percent of the new transmission line — a provision that sets the NCTL apart from large infrastructure projects of the past. It’s a deliberate shift toward Indigenous partnership, not just consultation.

Federal-provincial funding and regulatory steps that enabled construction

The $3.9-billion funding commitment came through the Canada–British Columbia Cooperative Prosperity Agreement, signed in July 2026, covering both phases of the NCTL and directed at building clean, reliable electricity infrastructure across the province.

The groundwork was laid months earlier. In November 2025, the Canada Infrastructure Bank provided a $139.5-million loan to BC Hydro to fast-track pre-construction work — engineering assessments, route clearing, and First Nations consultations. That early investment meant Phase 1 was ready to break ground without the delays that typically follow large-scale regulatory approvals. On November 13, 2025, the NCTL was referred to the Major Projects Office, a federal mechanism designed to accelerate regulatory coordination across departments.

Officials pointed to that referral as a key factor in the project’s unusually fast progression. The result was concrete: shovels in the ground less than a year after entering the regulatory fast-track, according to the Government of Canada.

Projected economic and emissions outcomes of the completed line

The numbers attached to the completed NCTL are significant. Once both phases are done, the project is projected to generate $10 billion in new economic activity and create nearly 10,000 jobs across British Columbia. On emissions, the line is expected to cut up to 3.3 million tons of greenhouse gases annually — roughly equivalent to taking one million vehicles off the road every year.

The NCTL is also designed to unlock specific industrial projects that have been waiting on transmission capacity. The Ksi Lisims LNG facility is one. Critical minerals developments in the Golden Triangle — a region with some of the richest mineral deposits in North America — are another. Without expanded grid access, those projects can’t move forward at scale. More than doubling clean electricity availability along the West Coast doesn’t just power existing communities; it opens the door to an entirely different category of industrial development in a region historically underserved by the grid.

Broader policy context: Canada’s National Electricity Strategy and grid expansion goals

The NCTL isn’t a standalone project. It fits within Canada’s National Electricity Strategy — a federal framework targeting a doubled national grid by 2050 to meet rising demand and secure domestic energy supply. That strategy is projected to deliver up to $15 billion in total energy savings by 2050 and lower total energy costs for seven in ten Canadian households.

The project also sits within the Northwest Critical Conservation Corridor, a federally designated region spanning Northwest B.C. and the Yukon, identified for its potential in critical minerals, energy, telecommunications, and transport. The NCTL serves as the corridor’s foundational infrastructure. Several federal financial tools support the broader strategy: the $4.5-billion Smart Renewables and Electrification Pathways Program targets priority areas in the electricity sector, Clean Economy Investment Tax Credits cover clean electricity and carbon capture, and the Indigenous Loan Guarantee Program has had its envelope doubled from $5 billion to $10 billion.

Canada already holds the lowest residential electricity costs in the G7 and the second-highest share of clean energy generation among G7 nations. The NCTL is designed to protect and extend that position.

What this means going forward

Phase 1 of the North Coast Transmission Line is now under construction — a 103-mile, 500-kV segment backed by $3.9 billion in federal-provincial funding, with First Nations holding co-ownership rights of up to 50 percent. Pre-construction financing from the Canada Infrastructure Bank and referral to the Major Projects Office allowed the project to move from regulatory approval to active construction within months.

When complete, the NCTL is projected to more than double clean electricity availability on B.C.’s West Coast, generate $10 billion in economic activity, support nearly 10,000 jobs, and cut up to three million tonnes of annual emissions. Industrial projects — from LNG to critical minerals — that depend on expanded transmission capacity will also be unlocked.

Phase 2 details and a broader construction timeline haven’t been publicly specified yet.
