Update on Hornsea One

Hornsea One is an offshore wind farm currently in construction 120km off the Yorkshire Coast. It is the first wind farm of its kind; when it is fully operational it will be the largest offshore wind farm in the world, and the furthest from shore a wind farm has ever been built.

On Friday 9 August, Hornsea One significantly dropped its power production, around the same time as another generation source lost load.

 

We are investigating the cause, working closely with National Grid System Operator which balances the UK’s electricity system. 

 

We will update you when more information becomes available.

A project spokesperson said: “During a rare and unusual set of circumstances affecting the grid, Hornsea One experienced a technical fault which meant the power station rapidly de-loaded – that is it stopped producing electricity. Normally the grid would be able to cope with a loss of this volume (0.8GW). If National Grid had any concerns about the operation of Hornsea One we would not be allowed to generate. The relevant part of the system has been reconfigured and we are fully confident should this extremely rare situation arise again, Hornsea One would respond as required.”
