Avista produces electricity using a number of different resources. In 2010, Avista generated or contracted to purchase for resale 5.91 million megawatt hours for our Northwest customers.
Our owned or contracted resources come primarily from four categories of fuel: biomass, coal, hydro, and natural gas. Avista’s fuel mix is as follows:
Natural Gas – 35.66 percent Hydro – 33.35 percent Coal – 26.52 percent Biomass – 2.49 percent Waste – 1.43 percent Nuclear* – 0.30 percent Cogeneration – 0.12 percent Petroleum – 0.08 percent Landfill Gases* – 0.02 percent Other – 0.02 percent
* Avista doesn’t own or operate landfill gas or nuclear generation facilities. We do however, purchase energy made within the Pacific Northwest, which includes some nuclear and waste generation.
In 2011, more than 70,000 mWh's, or about 1 percent, of Avista's resources came from wind and other renewables as a result of Buck-A-Block customer purchases.
