Austin Energy Launches 100 MW Battery Project with Jupiter Power

Austin Energy has entered into a large-scale battery storage contract with Jupiter Power to deliver up to 100 megawatts (MW) of stored clean energy from a utility-scale battery facility.

The project directly supports Austin Energy’s goal of achieving 125 MW of battery storage by the end of 2027, meeting the city’s climate and reliability targets. 

The flexibility offered by battery storage helps balance the integration of renewable energy sources, reduces reliance on fossil fuels, and improves overall system resilience during extreme weather events. 

The undertaking is Austin Energy’s largest battery storage initiative, valued at an estimated $14.4 million per year. With a term of up to 20 years, the total estimated amount is $288 million. 

“This agreement reflects a commitment to modernize the grid and ensure reliable, sustainable energy for Austin Energy customers,” said Stuart Reilly, Austin Energy interim general manager, in a statement. “Battery storage is an important component of our energy strategy, and we’re proud to bring this emerging technology online to benefit our community.” 

Battery integration on a utility-scale is part of Austin Energy’s Resource, Generation, and Climate Protection Plan to 2025, which outlines a plan for achieving a clean energy future that incorporates the community’s core values of reliability, affordability, environmental sustainability, and energy equity.  

Andy Bowman, Chief Executive Officer of Jupiter Power, added, “We are extremely pleased to be working with Austin Energy, a nationally recognized leader in grid reliability, clean energy and efficiency, to advance their energy storage goals — especially here, where Jupiter was founded. Austin Energy has a clear vision for the future, and as both a proud customer, with headquarters in Austin, and now partner, Jupiter couldn’t be happier to be a part of it.”
