Worldwide wind projects
RES have been involved in researching renewable technologies since the 1980s, and built their first wind farm in Cornwall, UK, in 1992. Within 10 years the company had completed the largest wind farm in the world at the time, in Texas. Today, with one of the largest project portfolios in the industry and an asset management portfolio exceeding 2 GW, RES continue to provide partnerships and services to the world's fastest growing energy sector.

The company's experience covers both utility-scale, centralized energy solar farms and distributed solutions, across the Americas and the EMEA region.

RES has the capabilities to develop, construct, operate, and optimize the operation of solar projects utilizing photovoltaic (PV) technology.

RESolve energy storage systems encompass the full life-cycle of energy storage solutions, from day-one modeling and in-house engineering, to construction and long-term management.

The company's systems are customized to meet the demands of any customer and bolstered by RES’ industry-leading expertise in development, engineering, construction, operations, finance, and project ownership.
