International Power Lines Permit Requirements

Summary#

The government published proposed International Power Lines (Permits) Regulations on December 14, 2024. They set what information must be given to the Canadian Energy Regulator when applying for a permit to build or operate cross‑border power lines and replace the old National Energy Board Electricity Regulations.

What it does#

• Establishes definitions (including how to treat “environmental effects” and “power transfer capability”).
• Sets application contents for permits for international power lines at two levels:
  • For lines at or below 50 kV: requires contact details, maps, a survey plan, technical specs, an environmental assessment unless an exemption applies, proof of public notice, approvals status, and recent financial reports.
  • For lines above 50 kV: requires more detailed route alternatives, environmental and land‑use criteria, detailed technical and reliability data (including seasonal power transfer capability), interconnection agreements, timetables, provincial approvals status, and an environmental assessment (which may be a provincial report).
• Provides a limited exemption for some small cross‑border segments that are built along existing linear works, if they meet conditions (no more than 4 km outside Canada; no supporting structures within 30 m of a body of water; and unlikely to release pollutants to water).
• Lists possible permit conditions, such as requirements on location, electrical characteristics, environmental protection and monitoring, approval for changes, and measures to protect power‑system reliability.
• Includes a form for an election under section 259 of the Canadian Energy Regulator Act (to confirm federal jurisdiction for a listed line).
• Repeals the National Energy Board Electricity Regulations.
• Says these Regulations come into force when the Export and Import (Orders, Licences and Permits) Regulations are registered (the exact date depends on that registration).

Note: This is a proposed regulation. The notice asks for comments within 45 days after publication.

Who's affected#

• Owners, operators and developers planning international power lines between Canada and the United States.
• Electricity utilities and transmission companies that would apply for permits.
• Provincial governments and regulators, because provincial approvals and coordination are part of permit files.
• People and communities near proposed routes, including Indigenous communities, since applications must address environmental, land‑use and traditional‑use effects and public comments.
• Parties on the U.S. side of a cross‑border line, because agreements and approvals outside Canada are required.

If it’s unclear who is affected in a specific case, the applicant or the Canadian Energy Regulator would determine what information is relevant for that permit application.

Why it matters#

• It clarifies what companies must file to get a federal permit for a cross‑border transmission line. That can affect how long and how costly project planning and review will be.
• The split at 50 kV means smaller lines face simpler requirements than larger lines.
• The rules require environmental assessments and details about impacts on existing power systems, which aims to protect communities, ecosystems and grid reliability.
• Repealing the old regulations and tying the start date to another set of export/import rules means timing and administrative details will depend on related regulatory steps.
• Because this is a proposal, interested people and groups have 45 days from publication to send comments.
