Onshore Wind

We were there at the birth of the renewables industry, pioneering research into wind energy technology in the early 1980s. We developed our first wind farm in Cornwall, UK in 1992 and, within a decade, had built the world’s largest wind farm at the time, at King Mountain, Texas. In the years that followed we constructed over 13GW of wind capacity across the globe, in North America and Europe and Australia.

Today, with one of the largest project portfolios in the wind industry, we continue to provide partnerships and quality services to the world’s fastest growing energy sector.

Join the 1% club

An impartial review carried out by DNV found that RES’ innovative approach, combining real-world experience with cutting-edge predictive software, made assets at least 1% more efficient, by reducing
unplanned downtime and component failures and improving availability. When applied to a typical 40MW wind farm, 1% equates to an extra £1m in revenue over the project’s lifetime.

Keir Harman, Renewables Operations Director for DNV, said: “Our review and findings of RES’ portfolio are a sign of confidence for investors and an endorsement of RES being able to deliver a lower cost of energy for its customers.”
