The electrical system connects the offshore array to the onshore grid connection point at the existing National Grid substation at Bicker Fen.
The power generated by the offshore wind turbines will be collected by the offshore substation platforms and transformed to a suitable voltage for export, before being exported by sub-sea and underground cabling.
The Electrical System covers the offshore export cable, the underground landfall infrastructure to the north of Anderby Creek and a new substation at Bicker Fen, ensuring the connection of the offshore turbines to the national grid onshore and ultimately into UK homes.
The consent application for the electrical system was accepted by the Planning Inspectorate (PINS) on 21 May 2015. A formal examination of the application was conducted and concluded on 3 March 2016.
A decision to grant consent was taken 3 September 2016 and issued by the Secretary of State for Business Energy and Industrial Strategy, Greg Clark, on 6 September 2016.

IEC removed from design
On 21 September 2017, we announced an update to our final design which removed the need for an Intermediate Electrical Compound which was originally planned to be constructed near the village of Orby.

Grid connection point
A robust process was followed in conjunction with National Grid to determine the appropriate interface point at which to connect the wind farm’s electricity into the existing national grid network.
The interface selection assessment report sets out the detailed process that was followed and explains the rationale behind the final selection of the existing Bicker Fen substation, near to Boston.

A robust site selection process was followed throughout the development of the Triton Knoll electrical system, which has taken on board a large amount of consultation information resulting in the locations that are now set out in the project consent documents.
The Site Selection and Design Report (SSDR) explains the rationale for the selection of the:
- Landfall to the north of Anderby Creek
- Offshore cable corridor route, connecting the offshore array to the landfall
- Site of the Intermediate Electrical Compound (IEC), near to Orby
- Site of the new Triton Knoll substation, near to Bicker
- Onshore cable corridor route, connecting the landfall, IEC (which has now been removed and is no longer part of the project design) and substation.
