Idaho Power provides electricity to more than 520,000 customers in our 24,000 square-mile southern Idaho and eastern Oregon service area.
In 2015, 77 percent of Idaho Power's supply of electricity came from company-owned generation resources. In above average water years, our low-cost hydroelectric plants are typically our largest source of electricity.
Idaho Power is one of the few investor-owned electric utilities with a predominantly hydroelectric generating base, which helps to keep your rates low. We own and operate 17 hydroelectric plants on the Snake River and its tributaries. We also deliver power to our customers through one diesel-powered generator and share ownership in three coal-fired generating plants; we do not operate any of them.
Idaho Power owns three natural gas-fired plants, including the Langley Gulch Power Plant. Natural gas-fired power plants burn natural gas and the hot gas spins turbine blades to produce clean, efficient energy.
The chart below shows Idaho Power's electricity sources for 2015 including generation from company-owned resources and purchased power.
Market Purchased Power is electric power purchased from other utilities in the wholesale electric market. Because we participate in the wholesale energy market, we sell electricity to other utilities and retail customers. Not all electricity purchased or generated by Idaho Power is delivered to our retail customers. Learn more about Electricity Delivered to Customers.
Long Term Power Purchases are electric power contracts with independent power producers and other entities and can typically be identified by resource type. Get details about Idaho Power's Fuel Mix.
