In 2011, 85 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.

The chart below shows Idaho Power's electricity sources for 2011 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, which includes an estimate of the fuel mix for Market Purchased Power based on the Northwest Power Pool's Net System Mix. Using the Northwest Power Pool's Net System Mix provides an estimate of the resource types and fuels used to supply our short term power purchases. This "mix" is an approximation of the types of resources and fuels that supply these short term market purchases.

The many benefits of hydroelectric generation include:

• Low cost
• Near emission-free
• Recreation opportunities
• Renewable (water is naturally replenished through the water cycle)

Successfully relicensing our hydroelectric power plants will enable us to defer building new and expensive generating resources and transmission lines.

By preserving our conventional baseload resources, such as those fueled by coal and natural gas (under development), Idaho Power provides safe, fair-priced and reliable energy to our customers.

(1) This is a disclosure of the generation resource types supporting our long-term purchases. Because Idaho Power intends to sell the Renewable Energy Certificates (RECs) that it owns in the near-term with proceeds benefiting retail customers, and since Idaho Power does not own the RECs for the other qualified renewable resources represented in the above Long Term Power Purchases by Resource Type chart, Idaho Power cannot and does not represent that electricity produced by this fuel mix is being delivered to its retail customers.
