esVolta, a major player in energy storage, has finalized a $110 million USD tax equity investment in collaboration with Greenprint Capital Management. This financing will support the construction of the Hummingbird project, a 300 MWh battery energy storage system located in San Jose, California, scheduled for completion by 2025.

Once operational, the Hummingbird project will provide resource adequacy capacity to Pacific Gas & Electric (PG&E) under a long-term contract. Additionally, it will play a central role in the California Independent System Operator (CAISO) market by offering fast-response energy services and solutions to reduce congestion and stabilize the power grid in a rapidly growing region.

Currently under construction, the project has already generated approximately 200 local union jobs, bolstering the regional economy.

A Strategic Partnership for Clean Energy

The transaction was facilitated with the support of Orrick, Herrington & Sutcliffe LLP, and DCH Law LLP for esVolta, while Greenprint Capital Management was advised by Leverage Law Group, LLC. This partnership marks a milestone for esVolta in its mission to modernize and decarbonize the U.S. power grid.

Randolph Mann, CEO and founder of esVolta, remarked: “This transaction reflects our commitment to developing innovative and reliable solutions for the U.S. energy grid. We thank Greenprint for their essential support.”

Peter DeFazio, Managing Director of Greenprint, added: “This financing aligns with our sustainable investment strategy and highlights our commitment to accelerating the energy transition. We are thrilled to collaborate with esVolta to build a cleaner energy future.”

Energy Storage: A Pillar for the Future

The Hummingbird project exemplifies the evolution of large-scale energy storage solutions. As renewable energy adoption accelerates, these technologies play a crucial role in addressing intermittency challenges and reinforcing grid stability.

By aligning with a sustainable vision, esVolta and its partners are tackling major challenges in modernizing the power grid while actively supporting the United States’ energy transition.
