The three-year contract with Statkraft extends an existing agreement and includes emergency support as well as preventive maintenance for one onshore and two offshore substations at the wind farm.

Alstom will maintain disconnectors, 132kV and 33kV gas insulated switchgear, 132kV and 33kV 90MVA transformers, a 132kV 60MVAr shunt reactor, substation automation and telecommunications systems and protection.

Alstom Grid vice-president for service, Jan Masschelin 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.

"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."

Statoil, Statkraft and the UK Green Investment Bank own the Sheringham Shoal wind farm through joint-venture company Scira Offshore Energy.

Located between 17km and 23km off the coast of North Norfolk, the wind farm features 88 Siemens 3.6MW turbines that generate enough energy for 220,000 homes.

The facility, which covers an area of about 35km², will reduce 500,000t of carbon dioxide emissions per year.

The lease for the wind farm's site was granted as part of the Crown Estate's Round Two in 2004.
