About the project

Why is it needed?

Existing transmission lines between the Pacific Northwest and Idaho Power’s service area can’t carry any more energy when it is needed most. B2H will provide the ability to deliver approximately 1,000 megawatts of clean, affordable power in each direction, helping Idaho Power meet customer demand, especially during summer peaks.

B2H is a cleaner, less expensive solution than building new carbon-emitting plants, and it’s less expensive than building new solar or battery storage plants. Visit Idaho Power's Clean Today, Clearner Tomorrow page for information on Idaho Power's commitment to clean energy.

Idaho Power's Integrated Resource Plans (IRP) have consistently identified B2H since 2009 as the lowest cost and least risk option for meeting projected customer demand. The IRP is a roadmap describing how Idaho Power plans to meet current and future energy needs over the next 20 years.

Benefits identified in the 2019 IRP include:

  • Greater access to the Pacific Northwest electric market
  • Improved system reliability and resiliency
  • Reduced strain on the regional power grid
  • Flexibility to integrate renewable resources and efficiently trade energy
