The four-hour battery storage project with up to 328 MWh from Prevalon will align with Idaho Power's plan to integrate more than 5,000 megawatts (MW) of energy from wind and solar projects over the next 20 years. The BESS will ensure energy produced by those intermittent sources can be stored for future dispatch. The company's "Prevalon Battery Energy Storage Platform," a complete AC solution including the battery enclosures, inverters, medium voltage transformers and EMS (Energy Management System), will be the cornerstone of the utility's battery storage project, which will make a significant contribution to Idaho Power's goal of providing 100% clean energy by 2045. The BESS from Prevalon is designed to meet the utility's specific needs, including robust safety and security protocols and reliable operations. The project is expected to be fully operational in 2025.

"This order is a testament to the hard work of a very talented team that has positioned Prevalon as a skilled and established business partner for our customers with deep project experience in the fast-moving and growing development of battery energy storage," said Prevalon President and CEO Tom Cornell. "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."

Battery energy storage has emerged as a critical technology in the march toward a cleaner, sustainable energy future. Prevalon is committed to innovating battery energy storage products and services to store electrical energy, much of it from renewable sources such as wind and solar, so that it can be utilized at a later time. This approach enables a more efficient, reliable, and sustainable electricity grid as it is designed to respond quickly to grid demand and supply changes.
