Resources and Transmission Services

Having a diverse energy mix is the foundation of Avista's ability to provide our customers with clean, reliable power at fair, reasonable rates. Hydropower is our single largest source of electricity, accounting for 40 percent of our generating capacity, followed by natural gas at 35 percent. We also have electricity generated by coal and biomass, with long-term contracts for additional hydropower and wind.

This diversified energy portfolio ensures we have a stable supply of power around the clock, every day of the year, today and in the future while helping keep our prices among the lowest in the nation for investor-owned electric utilities. It's also why the National Resources Defense Council, "Benchmarking Air Emissions of the 100 Largest Electric Power Producers in the United States," has ranked Avista among the cleanest utilities in the country when it comes to greenhouse gases.
