Our hydroelectric system provides safe, reliable and clean energy. Its history dates back to the California Gold Rush. The system is also the largest investor-owned hydroelectric system in the nation.
Hydroelectricity is generated by the force of falling water. Usually, a series of dams and reservoirs collect this water. The water is then directed through large pipes. The pipes are called penstocks. Turbines use this water to spin generators to form electricity.
Our system is regulated by the Federal Energy Regulatory Commission (FERC) and by the California Public Utilities Commission (CPUC). The two commissions create environmental and operational requirements.
Following are additional facts about our system:
