Idaho Power has submitted a 20-year plan to state regulators that phases out coal-fired power plants by 2028 as part of its effort to provide only clean energy by 2045, the company said Tuesday.
Idaho Power in a news release said its 2021 Integrated Resource Plan submitted to the Idaho Public Utilities Commission moves the company away from coal and toward renewable energy, battery storage, energy efficiency and additional power that will come with the completion of a transmission line connecting to the Pacific Northwest.
The 214-page document spells out how the company will meet energy demands in a 24,000-square-mile (62,000-square-kilometer) area in southern Idaho and eastern Oregon as its number of customers grows to nearly 850,000 from 600,000 by 2040.
Idaho Power is allowed to operate as a state-regulated monopoly in exchange for producing a reliable and affordable supply of energy to the region. The 20-year plan, updated and submitted every two years, tells state regulators how it intends to meet those responsibilities, while balancing costs and risks.
