Sumitomo Electric Industries, Ltd. has been awarded a contract by a UK Offshore Transmission Owner, Gwynt y Môr OFTO Plc. (GYM), to supply a 132-kV offshore export cable to transmit power from the Gwynt y Môr offshore wind farm, located approximately 15 km off the North Coast of Wales, to the onshore grid.

Sumitomo Electric stated that its submarine cable technology was selected by GYM to increase the reliability of its power transmission asset and maximise the availability of the wind farm.

“Sumitomo Electric aims to continue its contribution to support UK and EU governments’ offshore wind expansion plans towards net-zero 2050,”
said Mr. Yasuyuki Shibata, Managing Executive Officer of Sumitomo Electric.

The 576 MW
Gwynt y Môr offshore wind farm was built in 2015 and is operated by RWE with partners Stadtwerke München and Macquarie Infrastructure and Green Investment Group. Gwynt-y-Môr OFTO plc, a consortium of Balfour Beatty and Equitix, acquired the transmission assets of the project in 2015 through the Offshore transmission owner (OFTO) regime.

Over the past few years the wind farm has experienced multiple failures and outages caused by the export cables. Gwynt-y-Môr OFTO plc has repeatedly appealed to Ofgem for compensation during transmission downtime.
