To provide you with reliable energy at the lowest cost, we draw from a variety of energy options. Your energy might be coming from a hydroelectric, natural gas, wind, or solar plant that we own (or jointly own), or it might be power that we purchased on the wholesale market because it was a great deal. We also have a small amount of coal that we’re working on eliminating from our resource mix no later than 2035. We use our transmission lines and the regional power grid to move the lowest-cost electricity in real time from where it’s generated to where it’s needed.

Our Pelton Round Butte and Sullivan plants generate low-impact hydro power, having passed a rigorous certification process to demonstrate minimum impact on fish and wildlife. Only 33 U.S. hydro plants have earned this designation.
