Confederated Tribes of Warm Springs become 49.99% owners of Pelton Round Butte hydroelectric project

CTWS co-owns and co-operates the 500 MW project alongside Portland General Electric

Jan. 24, 2022

Warm Springs, Ore. — At the start of the new year, the Confederated Tribes of Warm Springs (CTWS) purchased an additional ownership interest in the Pelton Round Butte hydroelectric project, increasing the Tribes’ share from 33.33% to 49.99%. Pelton Round Butte is an emissions-free, three-dam complex on the Deschutes River co-owned by Portland General Electric (PGE). The Tribes became co-owners of the hydroelectric facilities in 2001 through an agreement that provided CTWS with an additional opportunity to purchase another 16.66% in 2021.

“Our longstanding relationship with this resource is something that is very important to our current tribal membership and to future generations,” said Jim Manion, general manager of Warm Springs Power and Water Enterprises. “We will continue to be good stewards of this precious resource that we have the responsibility of co-managing.”

“This agreement is a testament to our close partnership and shared commitment to the Deschutes River Basin,” said Maria Pope, president and CEO of PGE. “PGE is honored to continue working together with the Tribes in Central Oregon for years to come.” For more than forty years, CTWS and PGE have worked together to generate power and advance an ambitious set of environmental goals, including the reintroduction of salmon and steelhead runs to the Deschutes River.
