Environment Minister Steven Guilbeault Finalizes Clean Electricity Regulations Compliance Framework

MONTREAL — Minister of Environment and Climate Change Steven Guilbeault published the finalized text of the federal Clean Electricity Regulations (CER) on Monday, establishing performance-based greenhouse gas emissions intensity standards for thermal electricity generating stations while introducing expanded flexibility mechanisms to protect regional power grid reliability.

The finalized regulatory standards, promulgated under the Canadian Environmental Protection Act (CEPA), mandate that fossil-fuel generating units achieve an emissions intensity limit of 30 tonnes of CO2 per gigawatt-hour by 2035, while establishing tailored compliance pathways for natural gas units equipped with carbon capture and storage (CCS) or operating as emergency peaking assets during extreme weather events.

Balancing Decarbonization with Grid Reliability and Affordability Federal environmental modeling projects that transitioning to a net-zero electricity grid by 2035 will eliminate over 340 million metric tons of cumulative greenhouse gas emissions while positioning Canada to export clean electricity to the northern United States.

"Canadians want clean, reliable, and affordable electricity to power their homes, businesses, and electric vehicles," Minister Steven Guilbeault said in Montreal. "Following extensive technical consultations with provincial utilities, system operators, and industry leaders, these finalized regulations establish a clear, achievable standard for decarbonizing our electricity sector while providing provincial power operators with the operational flexibility needed to keep the lights on during extreme cold snaps and heat waves."

Key Regulatory Flexibility Mechanisms The finalized CER framework incorporates:

• 20-Year End-of-Prescribed-Life Provision: Units built before 2025 may operate unabated for up to 20 years from their commissioning date before becoming subject to emissions limits.
• Emergency Peaker Exemptions: Natural gas generation units operating under 450 hours per calendar year are exempt from emissions limits to serve as emergency winter backup.
• Carbon Capture Integration Credits: Providing compliance flexibilities for facilities achieving 90 percent carbon capture rates.

Clean energy advocacy coalitions commended the finalization of the regulations, while provincial power utilities noted that the amended emergency provisions provide a practical balance for system operations during extreme winter weather.
