Fortress Power has partnered with Renewable Energy Solutions (RES) to support commercial and industrial (C&I) battery energy storage system deployments across California, with continued project support in Hawaii.

Through this collaboration, the two teams aim to simplify the deployment of complex energy storage projects. RES will serve as Fortress Power’s exclusive partner for C&I deployments in California. In this role, the RES team helps coordinate engineering, project execution, and commissioning between contractors, engineers, utilities, and distribution partners.

As part of this collaboration, RES works closely with project stakeholders to specify Fortress Power energy storage systems that meet project requirements. In addition, each system aligns with UL standards, utility interconnection requirements, and AHJ codes. From early design through commissioning, the RES team collaborates with engineers and contractors to refine system designs, coordinate installation, and support system startup.“

“In today’s C&I market, delivering hardware and software alone is no longer enough.”

RES works closely with project stakeholders to specify Fortress Power energy storage systems that meet project requirements. In addition, each system aligns with UL standards, utility interconnection requirements, and AHJ codes. Throughout the project lifecycle, the RES team collaborates with engineers and contractors to refine system designs. The team also coordinates installation and supports commissioning to help keep projects on schedule.

“In today’s C&I market, delivering hardware and software alone is no longer enough,” said Jing Yu, CEO of Fortress Power. “Customers need white-glove technical expertise and hands-on support to navigate complex requirements. Our partnership with RES helps ensure projects move from concept to commissioning with the coordination and technical depth customers expect, especially in complex markets like California.”

As commercial energy storage adoption grows, projects require more than hardware. They depend on coordination across engineering, installation, compliance, and long-term system performance.

Because of this, the partnership between Fortress Power and Renewable Energy Solutions helps simplify complex C&I deployments. The collaboration supports projects as they move from design to deployment.

Together, the two teams are helping accelerate commercial energy storage adoption while strengthening grid resilience. Learn more about Fortress Power’s C&I energy storage solutions.
