Morven Hawthorn Pit grid connection

The Morven Hawthorn Pit grid connection consists of onshore and offshore infrastructure associated with the transmission of electricity generated by the wind farm array to the national grid.

It consists of underwater offshore and underground onshore electricity cables and a land substation.

The Secretary of State for the Department of Energy Security and Net Zero (DESNZ) has directed that the offshore and onshore elements of the Morven Hawthorn Pit grid connection that are within England should be consented via a Development Consent Order (DCO) under the Planning Act 2008.

For the section of the Morven Hawthorn Pit grid connection within Scottish waters, we will apply to the Scottish Government’s Marine Directorate for a Marine Licence under the Marine and Coastal Access Act 2009.
