UK goverment opens up offshore transmission review

General Interconnectors Windfarms

The Department for Business, Energy & Industrial Strategy (BEIS) has launched a new enduring regime for wind farm development and offshore transmission.

The Offshore Transmission Network Review aims to deliver improvements in the way that offshore generation is connected to the onshore transmission network and facilitate a more supportive approach for multi-purpose interconnectors

The current offshore transmission regime takes a developer-led approach to designing and delivering offshore transmission, which has resulted in individual connections for each wind farm, and dates from when offshore wind was a nascent sector.

BEIS is consulting on proposals to develop a new enduring regime that considers the offshore transmission system holistically with the onshore network to deliver a more coordinated approach in an effort to reduce the cumulative impacts of transmission.

Fundamental questions of the consultation include:
1. Is there a need for upfront strategic planning of offshore wind generation?
2. Is there a need for holistic network design and what are the fundamental design choices?
3. What are the possible delivery models?
4. What should the timing of transmission delivery be?

The document also investigates approaches taken in other countries and whether elements of these approaches should be considered.

BEIS outlined that it is not seeking to lock in a specific model at the moment, but will use feedback to inform further detailed assessment of individual options. It will then consult again on the detail later in 2021.

The consultation closes at 11:45pm on 23 November 2021.
