History of the Power Auction

On Feb. 11, 1998, the Federal Energy Regulatory Commission (FERC) issued an “Order Modifying Initial Decision," which requires Grant PUD to sell a portion of its firm and non-firm Priest Rapids Project power. We developed a marketing plan to comply with the FERC order. See details, below.




  • Be fair and equitable
  • Be non-discriminatory
  • Be pursuant to market-based principles and procedures

Grant PUD developed the "open-market auction" (power auction) process to establish the market price of project power in response to the FERC order.

The power auction is the first of its kind in the nation. The first power auction happened in 2005 and has been received well by the industry. It is our goal to not only meet the tenets of the FERC order but also provide access to our clean, renewable, hydro resource on the Columbia River.
