Supporting the offshore industry for 30 years

RES has a long history and broad base of experience in offshore wind, having been involved in the sector since its beginnings in the 1990’s. RES offers a range of offshore services including long term O&M packages as well as standalone services. 

By utilizing our 24/7 state-of-the-art control centre we provide balance of plant (BoP) services, including transmission services for the associated offshore transmission owner (OFTO) assets in the UK.
