We support renewable energy sources, including wind, geothermal, biomass, cogeneration and small hydro. Find out details about each.
When Elkhorn came online in 2007, Idaho Power had just 10-20 MW of wind energy tied to our system. Our long-term planning process identified a need for additional wind energy, and we now have a 20-year contract to purchase the energy from this project.
Since then, additional projects have come online under a federal law that requires Idaho Power to purchase energy from qualifying renewable energy sources such as wind, solar and geothermal. As of 2020, Idaho Power had a total of 728 MW of wind capacity tied to our system.
The rate Idaho Power pays for Elkhorn energy is set each year and escalates over the term of the contract. We expect to receive about 300,000 renewable energy certificates (REC) per year throughout the term of our agreement. Currently, the RECs are sold, and the proceeds are shared with our customers. Because the RECs are sold, Idaho Power cannot claim renewable wind energy from this project is being delivered to customers.
Independent Power Producers
As of 2020, Idaho Power had contracts with 32 other commercial wind projects, representing 627 megawatts of nameplate capacity (possible energy). These are 20-year contracts mandated by a federal law that requires utilities like Idaho Power to purchase all the energy generated by certain projects. The rates we pay for energy from these projects varies, but it’s higher than the rate we pay for energy from Elkhorn.
Idaho Power does not own or operate these projects.
Wind generation usually operates well below its actual capacity. To see the actual amount of energy generated by wind on Idaho Power’s system relative to the capacity and the total electricity demand over the past 48 hours, visit the System Load and Wind Generation page.
The 120-MW Jackpot Solar project south of Twin Falls, Idaho, began generating energy in late 2022.
