Fast Facts: Power Use for Mine Ventilation
A large exhaust fan drawing will move air out of the mine 24 hours a day
Air from the mine will be exhausted through the mine’s headframe at approximately 165’ above ground. The ventilation fan exhausting the air will operate continuously, 24 hours a day, every day, at 200,000 cubic feet per minute.
The permit application estimates a PG&E power net load of 6,000 Kilowatts (KW). Total power is estimated at 42,757,000 Kilowatt-Hours (KWH) per year. This is approximately equivalent to the power used by 5,000 houses.
