Pelton Dam, built in 1958, is a concrete arch dam that forms Lake Simtustus. The Pelton Round Butte hydroelectric project was completed in 1964 and includes three dams situated along a 20-mile stretch in the Deschutes River canyon. PGE co-owns and co-manages the project with the Confederated Tribes of the Warm Springs Reservation of Oregon (photo courtesy of PGE).

In operation since 1974, the Beaver Power Plant consists of six GE 7B combustion turbines with by-pass stacks and heat recovery steam generators. Those generators feed steam to a single steam turbine for a combined electric generation capacity of 500MW. Beaver is normally fueled by natural gas with ultra-low-sulfur diesel fuel available for contingency operation. When not in operation, the gas turbines are usually maintained in standby, capable of being brought on line in 20 minutes (photo courtesy of PGE).

The Circulating Water system is primarily used to remove heat from the steam turbine main condensers. The system facilitates turning low-energy steam back into water for re-use in the steam plant. It also provides for heat removal from other plant systems during operation.

Wind turbines generate power at Biglow Canyon Wind Farm, PGE’s first wind farm. It has a total installed capacity of 450 MW. Given the variability of wind power, the plant generally produces enough energy to power the homes of about 125,000 average PGE residential customers (photo courtesy of PGE).
