Jupiter Power LLC has announced the commencement of commercial operations at its Callisto I Energy Center, a 400MWh battery energy storage facility in Houston, Texas. This significant addition to the ERCOT grid is designed to provide dispatchable, zero-emissions power, meeting the rising demand in the Houston area. The Callisto I project is the largest energy storage initiative in Houston and represents a key step in enhancing the region's energy resilience, particularly during extreme weather events.

Located on the site of a former fossil fuel power plant, the Callisto I Energy Center has a capacity of 200MW/400MWh and is capable of expansion to accommodate an additional 400MW/800MWh of battery storage. The project aligns with recent legislative efforts to increase the availability of affordable, dispatchable power in Texas, reflecting a shift toward sustainable energy solutions.

Andy Bowman, CEO of Jupiter Power, expressed pride in the completion of the Callisto I project, noting its importance in meeting Houston's growing power needs while contributing to a more resilient energy grid. Jane Stricker, Senior Vice President of the Greater Houston Partnership, highlighted the project's role as Houston's first large-scale, transmission-connected energy storage system, emphasizing its significance for the region's energy future.

The Callisto I project is part of Jupiter Power's broader strategy to expand large-scale battery storage beyond West Texas, further solidifying its presence in the ERCOT market, where it now operates a total of 1,375MWh across nine projects.
