Overview
- The sixth and final generating unit was commissioned in August 2025, marking Site C’s transition to full operational status after initial power production began in October 2024.
- The dam now delivers 1,100 MW of clean electricity—enough for roughly 500,000 homes—and boosts BC Hydro’s total supply by about eight percent.
- Project costs reached $16 billion, nearly double the original $8.8 billion budget, making Site C B.C.’s most expensive infrastructure undertaking.
- BC Hydro forecasts the facility will serve customers for the next century and play a critical role in advancing the province’s long-term clean energy strategy.
- Remaining tasks, including road paving, final equipment commissioning and environmental stabilization, are scheduled through spring 2026 before reservoir access is allowed.
