Renewable Energy

Hydroelectric energy — the power of falling water — has provided the backbone of Idaho Power’s generation since the company was founded in 1916. Other renewable energy sources, such as wind, solar and geothermal, have increased over the years. Because Idaho Power sells (or does not own) the renewable energy certificates or “green tags” associated with certain renewable-energy sources, and uses the proceeds to benefit customers, we do not claim renewable energy from those projects is delivered to customers.


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


Idaho Power supports the Elkhorn Valley Wind Project in northeast Oregon, which came online in 2007. We have a 20-year agreement to purchase all the electricity produced there.


In 2017, 120 megawatts (MW) of capacity from new solar projects came on-line, contributing to a current total of more than 1,000 MW from 47 independent solar and wind projects.
