Long-Term Power Purchases are electric power contracts with independent power producers and other entities and can typically be identified by resource type.
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.

We operate 17 hydroelectric projects on the Snake River and its tributaries. Together, these projects make up our largest generation source.

Idaho Power buys energy from numerous solar producers with a combined capacity of over 400 megawatts.

Idaho Power is moving away from coal. To serve customers reliably, we produce energy from natural gas.
