Idaho Power is a U.S. regulated power utility serving eastern Oregon and southern Idaho. Its 24,000-square-mile service area generally follows the terrain around the Snake River, and its tributaries. As might be expected it has 17 hydroelectric dams, plus 3 natural gas and 2 coal power stations. Idaho Power’s first large battery storage announced May 2, 2022 is a logical extension to this largely green heritage.
Idaho Power’s First Step In Large Battery Storage
The utility intends to provide 100% clean energy by 2045. Meanwhile, the 120 megawatts of new battery storage will contribute to greater reliability during periods of high demand. “This is an exciting step for Idaho Power,” says Senior Vice President and Chief Operating Officer Adam Richins.
“Not only are we adding capacity to serve our customers. We are also taking advantage of advancements in technology that will be key to our future. Battery storage enables us to use existing generation sources efficiently, while preparing for more clean energy in the coming years.”
New 120 Megawatt Large Battery Online Next Summer
Idaho Power intends the new battery will be ready for summer 2023. This time frame is immensely sooner than any new hydroelectric, natural gas, or coal power station. The company applied for a Certificate of Public Convenience and Necessity from Idaho Public Utilities Commission on April 29, 2022.
The first 40 megawatts of storage may go to the proposed Black Mesa solar facility in Elmore County. While the remaining 80 megawatts will probably go to Hemingway substation near Melba. However both locations are still tentative at this stage.
Taken together, the company’s planners believe these, or similar arrangements will make a difference during 2023’s anticipated hot summer. A 40 megawatt big battery is sufficient to power 13,000 homes for four hours, and then recharge again over a similar time.
