Power supply

The Eugene Water & Electric Board is committed to providing its customers with reliable, cost-effective sources of power that have minimal impact on the environment. More than 95% of the electricity EWEB needs to serve its customers comes from hydropower, wind and other sources that do not generate carbon-based emissions that are linked to global warming.

Most of this electricity comes from the federal Bonneville Power Administration and from EWEB's own hydroelectric projects. EWEB also has been at the forefront of renewable energy resource development. We were the first public utility in Oregon to own a wind farm, and now own or contract for portions of four wind farms and four biomass cogeneration plants.

EWEB currently is seeking a new federal license to operate its Carmen-Smith Hydroelectric Project on the upper McKenzie River. Read more about this process and any other relicensing efforts.

Integrated Electric Resource Plan (IERP)

Acquiring new sources of electricity, such as renewable power, is the result of a careful planning process used by EWEB for the past 25 years to determine what energy resources it will need in the future. The Integrated Electric Resource Plan is updated every few years with the help of citizens.

EWEB's current plan includes the following two directions:

  • Continue conservation programs, and ramp up if EWEB's need for power goes up
  • Increase the diversity of EWEB's energy resource portfolio, with a preference for renewable resources and local cogeneration

Since the completion of the last IERP in 2004, EWEB's conservation programs have saved an additional 142 million kilowatt hours, which reduced EWEB's total demand by 5.8% below what it would have been without our programs. EWEB has also acquired potions of two new wind projects and two biomass cogeneration projects with combined output of 275 million kilowatt hours per year.
