Visit to a Project at John Day Pool

June 11, 2018|Energy Blog

Staff at the office, along with folks from Ecology, visited the Klickitat County PUD1 site for a closed-loop pump storage hydropower project at the John Day pool. This is being funded in part by the Clean Energy Fund through appropriations by the 2018 legislature.

Site for the John Day ProjectA closed loop system consists of two reservoirs at different elevations, and apart from a free flowing water source, such as a river. They have fewer environmental impacts. The system generates power as water moves down through a turbine and draws power as it pumps water to the upper reservoir.

Pumped-storage hydro-power currently accounts for 95 percent of all utility-scale energy storage in the United States.
