Renewable Energy PPA: Idaho's Bold Leap into Battery Storage with Mitsubishi's Prevalon

published on 02 April 2024


In an era where renewable energy is rapidly becoming the cornerstone of a sustainable future, Idaho is making a monumental stride with the help of Mitsubishi's spinoff, Prevalon Energy. This collaboration is set to revolutionize the way we store and utilize energy, ensuring a more resilient and efficient power grid. Join us as we delve into the details of this groundbreaking project and its implications for the energy sector.

A Beacon of Grid Resiliency

At the heart of this partnership is the construction of a comprehensive Battery Energy Storage System (BESS) by Prevalon Energy, a subsidiary of Mitsubishi Power Americas. With a staggering capacity of 328 MWh, this four-hour battery storage project is designed to bolster grid resiliency, providing a net peak solution that enables Idaho Power to supply electricity during peak demand periods. This initiative is not just about meeting immediate energy needs but is a strategic move to future-proof the grid against fluctuations and uncertainties.

Integrating Renewable Energy Sources

One of the most exciting aspects of this project is its alignment with Idaho Power's ambitious plan to integrate over 5,000 MW of energy from wind and solar projects in the next two decades. The BESS will play a crucial role in storing energy generated from these intermittent sources, ensuring that it can be dispatched when needed. This seamless integration of renewable energy into the grid is a significant step towards a cleaner, more sustainable energy landscape.

A Testament to Innovation and Collaboration

The Prevalon Battery Energy Storage Platform, encompassing battery enclosures, inverters, transformers, and an Energy Management System (EMS), is set to be the cornerstone of this initiative. Prevalon's President and CEO, Tom Cornell, emphasized the importance of a partnering mindset and the company's commitment to working closely with Idaho Power. This collaboration is a testament to the innovation and expertise that Prevalon brings to the table, leveraging its experience from over 30 BESS projects globally.


The partnership between Idaho Power and Mitsubishi's Prevalon Energy is a beacon of progress in the renewable energy sector. By harnessing the power of battery storage, Idaho is setting a precedent for grid resiliency and sustainability. As we look towards a future powered by renewable energy, initiatives like this are pivotal in shaping a greener, more resilient world.
