How We Assess Power Resources

Resource planning is one of our most important tasks, as the cost of our power supply requires nearly 70 percent of the electric utility budget.

Fortunately, our area is served largely by clean, renewable hydropower. About two thirds of our supply comes from the Bonneville Power Administration, a federal agency that markets hydroelectricity created by dams on the Columbia and Snake rivers. Another third of our power comes from the River Road Generating Plant, a combined-cycle combustion turbine fueled by natural gas. Located in Vancouver, it was completed in 1997.
