Competition ramps up as bidders revealed for UK transmission tenders

In: CablesWindfarms
The Office of Gas and Electricity Markets (Ofgem) has revealed the shortlist of bidders to tender for the Triton Knoll and Moray East offshore wind farm transmission assets.

Located 22km from the coast in the Moray Firth, Scotland,
Moray East is being developed by a joint venture company owned by Diamond Green Limited (33.4%), EDPR (33.3 %), ENGIE (23.3%) and CTG (10%). The project is currently under construction and will feature 100 MHI Vestas V164-9.5 MW turbines, three offshore substations and three export cables.

Located over 32 km off the Lincolnshire coast,
Triton Knoll is jointly owned by RWE (59%), J-Power (25%) and Kansai Electric Power (16%), with RWE leading the wind farm’s construction and long-term operation and maintenance works, on behalf of the project partners. Work to install the 90 Vestas V164-9.5 MW turbines is ongoing, and the project will connect to shore via two offshore substations and export cables.

The transmission systems for the the two wind farms are currently being tendered under the seventh round of the Offshore Transmission Owner (OFTO) regime. The seventh round has an estimated value of £1.3 billion and will connect more than 1.7 GW of generation capacity.

The shortlisted candidates include the 'usual suspects', to progress to the final Invitation to Tender (ITT) Stage.

Diamond Transmission Partners is a consortium of Mitsubishi Corporation and Chubu Electric Power Co., Inc. Equitix TEPCO Consortium is a consortium of Equitix Limited and TEPCO Power Grid Incorporated. Transmission Capital Partners is a consortium of International Public Partnerships Limited and Transmission Capital Partners Limited Partnership.

The ITT stage for the Triton Knoll project will commence shortly, with the Moray East ITT expected to commence in August 2021.

Following the ITT stage, Ofgem will appoint an OFTO for each link. The OFTO will receive a guaranteed revenue stream under the terms of their licence, subject to the availability of their assets.
