Energy Northwest supports public power in the areas of operations and maintenance of generating facilities and electric utility automation.
During 2014 EN took over operations of the 15-MW Tieton Hydroelectric Project at Rimrock Lake in Yakima County, under contract with the city of Burbank, Calif.
In 2017 Energy Northwest set up operations for the
first time in Oregon, taking over operation of two powerhouses on the Bull Run
River for the city of Portland. Each about 25 miles southeast of the city, one
of the dams was built in 1929 and has a 25-megawatt powerhouse, and the other
in 1962 with a 12.5-MW powerhouse. Portland residents receive all of their
drinking water from the reservoirs provided by these two dams.
