Working with ORE Catapult, Transmission Excellence has completed a detailed study of lightweight offshore substations. These are offshore substations that can be installed by the same vessels that are used to install the wind farm that they serve. They also sit on substructures that are adapted from those use by the wind turbines, and in some cases both substation and wind turbine can share the same substructure.
The report, which was undertaken for the Offshore Wind Programme Board’s Grid Group, concludes that this approach has the potential to reduce the cost of offshore wind by £1.7/MWhr.
