Alstom has been awarded a three-year service contract by Statkraft for the substations of the 317 MW Sheringham Shoal offshore wind farm, located off the coast of North Norfolk, England. The contract, an extension of an existing one, covers emergency support as well as preventive maintenance for one onshore and two offshore substations serving the wind farm.
The Sheringham Shoal wind farm consists of 88 wind turbines. It produces enough electricity to power around 220,000 homes and displaces about 500,000 tonnes of CO2 every year.
The scope of the maintenance contract includes disconnectors, 132 kV and 33 kV gas insulated switchgear, 132 kV and 33 kV 90 MVA transformers, a 132 kV 60 MVAr shunt reactor, substation automation as well as telecommunications systems and protection. It also includes a 24/7 rapid response to the customer.
Jan Masschelin, Vice President Service of Alstom Grid, said: “Alstom designed and built the onshore and offshore substations for the wind farm in 2011 and maintained it since then through on demand support. We are delighted to continue to contribute to this project, one of the biggest offshore wind farms off the coast of the United Kingdom. Our local team will bring its experience in servicing high voltage substations, even located in a difficult environment, to ensure optimal asset performance and reliability to our customer.”
