Gwynt y Môr

Welcome to RWE Innogy's flagship Gwynt y Môr Offshore Wind Farm - now the second largest operating offshore windfarm in the world.

A greater than £2billion project, Gwynt y Môr consists of 160 turbines has been built by RWE Innogy UK in Liverpool Bay, off the North Wales coast. The project was funded by RWE Innogy, in partnership with Stadtwerke München GmbH, and Siemens AG.

Operationally, Gwynt y Môr has an installed capacity of 576MW, using Siemens 3.6MW turbines and generators. It is capable of generating enough energy to meet the average annual energy needs of around 400,000 homes (1).

The wind farm, including all 160 foundations, turbines, onshore and 2 x offshore substations was officially inaugurated on 18 June 2015.

(1) Footnote:(Energy predicted to be generated by the proposal is derived using wind speeds monitored in the local area. This enables a calculation to be made to estimate the average annual energy production for the site based on 160 turbines each of rated capacity 3.6 MW. The energy capture predicted and hence derived homes equivalent figures may change as further data are gathered.

Equivalent homes supplied is based on an annual electricity consumption per home of 4700 kWh. This figure is supported by recent domestic electricity consumption data available from The Digest of UK Energy Statistics and household estimates and projections from the UK Statistics Authority.)
