Our Path Away from Coal

Serving customers with reliable, affordable, clean energy has been the hallmark of our 100-year history. Our Clean Today, Cleaner Tomorrow® campaign demonstrates our commitment to a clean-energy future.

Our Goal: Deliver 100% Clean Energy by 2045

Our current energy mix has given us a great start on our path to 100% clean. To keep us moving forward, we’ve set some interim targets for further reducing carbon emissions. You can track our progress here.

Reducing Carbon Emissions Intensity

Carbon emissions intensity is a measure of the pounds of COemitted per megawatt-hour (MWh) of energy generated. It’s a helpful measure for tracking the impact of our efforts to reduce carbon emissions relative to growing power demand — one that we’ve measured and actively reduced over the last decade.

  • We started with a goal to reduce emissions 10-15% from 2005 levels.
  • We then increased it to 15-20% for the period of 2010-2020.
  • In May 2020, Idaho Power’s Board of Directors approved a revised goal – reducing carbon emission intensity by 35% for the period from 2021-2025 compared to the baseline year of 2005.

From 2010 to 2019, we reduced the COour energy sources emit by an average of 28.98% compared to 2005.

The chart below tracks Idaho Power’s progress since 2005 toward meeting our goals.

The chart above includes emissions and generation from Idaho Power-owned generation resources only. If Idaho Power has sold any Renewable Energy Certificates (RECs), the renewable generation creating those RECs is not included in this CO2 emissions intensity calculation.

Retiring Coal Plants

Idaho Power is a joint owner of three coal plants. With upcoming anticipated coal plant retirements, and constructing transmission lines instead of new plants, we are poised to see impressive reductions in both our total carbon emissions and emission intensity in the next 10 years.

  • The Boardman plant in Oregon ceased coal-fired operations in October 2020. Idaho Power owns 10% of this plant, and Portland General Electric owns the rest.
  • The North Valmy plant in Nevada includes two generating units, which are co-owned by Idaho Power and NV Energy. Idaho Power ended its participation in North Valmy unit 1 in 2019 and has an agreement to exit unit 2 by 2025. Both companies own 50% of the plant; NV Energy is the operating partner.
  • The Jim Bridger plant in Wyoming is owned by Idaho Power (one-third) and PacifiCorp (two-thirds). Idaho Power is working with PacifiCorp and regulators to explore options for continuing to reduce emissions from the plant, including the early retirement of two of Jim Bridger’s four units.
