How We Generate Electricity

A diverse mix for a dependable future

Where your electricity comes from

Power sources are shown as a percent of total system load. Our wind, solar and hydro segments include long-term contracts as well as PGE-owned resources. This chart does not reflect our use, generation or administration of renewable energy certificates, which we used to help ensure we met the State of Oregon’s Renewable Portfolio Standard in 2018.

PGE generates electricity from plants we own, and purchases power on the wholesale market to assure we serve customers with the lowest-cost resources available at any given time. We operate wholly and jointly owned hydroelectric, natural gas, coal, wind and solar generating plants.

We also own transmission lines, which as part of the regional power grid allow us to move the lowest-cost electricity in real time from where it’s generated to where it’s needed.

PGE meets our area’s growing energy demands with a diverse mix of generation facilities that includes water power, wind, coal and natural gas combustion. See the chart below for the generating capabilities of our seven hydroelectric plants, two wind farms and seven thermal plants.

We also own major transmission rights to the Pacific Intertie, the West Coast electrical superhighway. These power exchange lines give us the flexibility to buy and sell power to other utilities when it’s not needed by our customers.

We manage the output of our own power plants in conjunction with available power supplies on the wholesale market to deliver power to our customers at the lowest price possible.
