Prevalon Energy, a subsidiary of Mitsubishi Power Americas, has been selected by Idaho Power for a four-hour battery energy storage system (BESS) project with up to 328MWh capacity in Idaho.

The project has been designed to align with Idaho Power's strategy to integrate more than 5GW of energy from wind and solar projects in the next two decades.

Prevalon claims that its BESS is designed to satisfy the utility's unique needs, including strict security and safety protocols and reliable operations.

The project is slated to become fully operational by 2025, contributing to grid resilience and acting as a net peak solution to support reliable power supply during high demand periods.

The service agreement for the project encompasses maintenance and remote monitoring.

This system will store energy generated from intermittent sources such as wind and solar, allowing for its use when needed.

Prevalon's 'Battery Energy Storage Platform' includes battery enclosures, inverters, medium voltage transformers, and an energy management system (EMS).

Prevalon president and CEO Tom Cornell said: “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.

“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.”

Last month, Mitsubishi, the parent company of Prevalon, partnered with PTT, a Thai state-owned oil and gas company, to explore the feasibility of using 100% ammonia in gas turbine power generation in Thailand.
