Building the Next Generation of Energy

Renewable energy is integral to the future of power generation. Over the past fifteen years, Rosendin has helped our client’s harness and deliver nearly 32 GW of clean, renewable energy.

Our dedicated Rosendin Renewable Energy Group (RREG) partners with clients early in the project development phase. This allows us to provide critical insights into constructability, system performance, and service considerations before the final design is set.

The RREG has delivered extensive design-build expertise and turnkey EPC capabilities to over 330 projects across the United States, Canada, Puerto Rico, and Guam, ranging from 500 kW to over 720 MW. Our comprehensive services include:

  • Project feasibility and energy performance analysis
  • Engineering
  • Procurement
  • Construction

Battery Storage

Energy Storage Systems (ESS) will play a critical role in ensuring sustainable growth and grid stability for the renewable energy industry over the next decade. Given the destabilizing impact that cumulative solar and wind projects can have on regional transmission and grid networks, ESS provides essential power ramping support, frequency regulation, curtailment de-risking, and back-up power. This directly mitigates ongoing challenges in renewable energy grid integration.

Rosendin has been installing Battery Energy Storage Systems for diverse clients across multiple market applications for decades. Leveraging our leadership position in the renewable energy industry, we are now utilizing our extensive BESS experience and expertise to provide best-in-class BESS integration services in conjunction with our utility-scale solar and wind offerings. Rosendin’s energy storage solutions are meticulously tailored to meet specific customer requirements while upholding the quality and safety standards we’ve been known for since 1919.
