Battery Storage

Energy Storage Systems will play a critical role in assuring sustainable growth for the renewable energy industry over the next 10 years. Given the destabilizing impact cumulative solar and wind projects have had on regional transmission and grid networks, ESS provides the power ramping support, frequency regulation, curtailment de-risk, and back-up power necessary to mitigate continued renewable energy grid integration challenges. Rosendin has been installing Battery Energy Storage Systems for many clients across multiple different market applications for decades. Given our leadership position in the renewable energy industry, the company is now leveraging its long-standing BESS experience and expertise to provide best in class BESS integration services in conjunction with its Solar and Wind Utility-scale offerings. Rosendin’s energy storage solutions are tailored to meet the requirements of the customer while maintaining the quality and safety Rosendin has been known for since 1919.
