Fuel Mix
Grant PUD Power Sources
The majority of Grant PUD’s power is generated from our own hydropower resources – Wanapum and Priest Rapids dams located on the Columbia
River just down river from Vantage. We also purchase power from the Bonneville Power Administration and the open energy market. These energy purchases include power from resources other than hydropower.
Each year the Washington State Office of Trade and Development publishes fuel mix generation categories and percentage calculations based on data from regional power suppliers. The power generation categories for Grant PUD’s 2010 report are listed here in alphabetical order.
