Key Capture Energy develops, owns and operates large-scale battery energy storage systems in the United States. Founded in 2016 by two founders, the company has grown to over 85 employees across 25 states, and describes itself as one of America's largest owner-operators of stand-alone battery storage projects. Its work spans utility-scale project development, construction, ownership and operations, with a focus on the technical challenges of grid-scale storage: integrating intermittent wind and solar generation and providing reliability and flexibility to the US power grid.
The company's assets consist of stand-alone battery energy storage facilities that it constructs, owns and operates, with over 620 MW operating today. A further development pipeline exceeding 8,000 MW is spread across 19 states. Technical domains include battery energy storage systems, grid-scale energy storage, renewable energy integration, power grid reliability and flexibility, and utility-scale project development and operations. Offices are located in Albany, NY; Houston, TX; and Salt Lake City, UT.
Key Capture Energy was acquired by SK E&S in 2024. The company states a goal of placing battery energy storage facilities in every US state and of contributing to a doubling of the nation's battery energy storage capacity in the coming years.
