Prevalon said the project provide grid resiliency as a net peak solution and help the utility to provide reliable power during peak demand period, though it didn’t reveal the location. Idaho Power is active in the states of Idaho and Oregon.

It is the second major announced grid-scale BESS project from Idaho Power, which is also a transmission system operator (TSO) and operator of gas plants and hydropower and is aiming for 100% clean energy by 2045. Last year saw construction start on 524MWh of projects using BESS equipment from system integrator Powin.

Prevalon’s BESS offering – the Prevalon Battery Energy Storage Platform – is, the company says, a complete AC solution including the battery enclosures, inverters, medium voltage transformers and EMS (energy management system).

Thomas Cornell, CEO of Prevalon having led Mitsubishi Power Americas BESS activities since 2017, commented: “We place high value on the partnering mindset and are looking forward to working closely with Idaho Power as they incorporate our end-end integrated battery energy storage solution into their long-range plans to ensure a stable and reliable energy grid for their customers.”
