EsVolta

esVolta, LP operates as a developer, owner, and operator of utility-scale energy storage projects across North America. The company was founded in December 2017 by Randolph Mann, an energy executive with over two decades of experience in strategic growth initiatives within renewable energy, microgrids, and energy storage. Before establishing esVolta, Mann held several key positions, including President of Salt Creek Energy Advisors, Vice President of Development at NRG Energy, and Vice President of Development at Edison Mission Energy, reflecting a career dedicated to advancing energy solutions. In July 2022, esVolta was acquired by Generate Capital, a sustainable infrastructure investment and operating platform, a move intended to accelerate the availability of energy storage projects.

The firm's business model encompasses the entire project lifecycle, from origination and development to construction, financing, and long-term operation. esVolta serves a client base that includes electric utilities, grid operators, and large energy users, providing them with solutions for on-demand capacity, energy arbitrage, and ancillary grid support services. Revenue is generated through the ownership and management of these large-scale battery energy storage systems (BESS), which deliver reliable electric capacity and other services to the grid, often under long-term contracts with energy commodity firms and community choice aggregators.

esVolta's core service is the deployment of standalone, utility-scale battery storage facilities that help stabilize the electric grid. These projects are critical for balancing the intermittent nature of renewable energy sources like solar and wind, reducing reliance on fossil fuel plants, and improving overall power quality and reliability. The company utilizes technologies such as lithium-iron phosphate batteries in its projects. For instance, its portfolio includes several major projects in Texas, such as the Anole (480 MWh), Desert Willow (300 MWh), and Burksol (200 MWh) facilities, which collectively provide nearly 1 GWh of capacity to the ERCOT market. As of mid-2025, the company has over 1.4 GWh of projects operating or in construction and a development pipeline of more than 30 projects totaling nearly 25 GWh.
