Beaver Combustion Plant
The Beaver Combustion Plant takes its name from the site on which it was built, the Beaver Army Ammunition Depot, a major army shipping point for the Pacific Theater of Operations.
In 1973 stream flows and reservoir levels hit record lows. The threat of a power shortage was enough to make PGE bring the Station L steam plant out of a nine-year retirement for 60 days of emergency service. To ensure there would be more emergency generation on hand in the future, work began on the Beaver Combustion Turbine Plant at Port Westward, 60 miles northwest of Portland on the Columbia River.
After investigating several sites, PGE selected the former Beaver Army Ammunition Depot on the Columbia River near Clatskanie. The Port of St. Helens, who owned the 800-acre site, leased it to PGE for a term of about 93 years. The Beaver Plant itself would take about 125 acres and include a large dock on a deep-water channel suitable for oil delivery by tanker ships, on-site rail facilities and a nearby state highway. These were important because the plant would burn fuel oil brought in by barge along the river and freight cars by the railroad spurs.
On Aug. 1, 1974, ahead of schedule, Beaver began commercial operation. In May 1975, PGE added a combined steam-generating turbine to utilize the waste heat exhausted by the gas turbines. The combined cycle generating facility was operational by Oct. 31, 1977, right on schedule. When not in operation, the gas turbines are usually maintained in a standby mode, capable of being brought online in 20 minutes.

Location
Clearing the site began in May of 1973, including the removal of 20 large concrete and earth ammunition storage bunkers, and construction began in September. The six industrial-type combustion gas turbine generating units use a wide variety of oil fuels and were designed for combined-cycle operation, using the high-temperature exhaust gases in heat recovery boilers to produce steam for a turbine generator. The turbine generators were installed in a single 479-foot building, the turbine on each unit directly connected to an air-cooled generator, each unit 140-feet long, 56-feet wide and over 42-feet high.
