UK: Ofgem appoints preferred bidder for Humber Gateway offshore transmission assets

This completes the procurement of Tender Round 3 offshore transmission owner (OFTO) projects.

Balfour Beatty Equitix Consortium, a consortium comprising Balfour Beatty Investments Limited and Equitix Limited, was selected by Ofgem through a competitive process in which bidders compete to become OFTOs. The tender exercise saw the lowest bids to date as a proportion of asset value demonstrating the value of using competition to drive down the costs of the networks for connecting offshore wind. 

The Humber Gateway offshore wind farm, located in the North Sea approximately eight kilometres off the coast of East Yorkshire, comprises 73 wind turbines and has a total installed capacity of 220MW. The estimated value of the transmission assets is £173.3 million. The transmission assets for the project are currently owned and have been constructed by E.ON Climate and Renewables UK Humber Wind Ltd and will transfer to the OFTO at licence grant.

The Humber Gateway transmission assets are being tendered under Tender Round 3. Since the offshore transmission regime was set up by Ofgem and the Department of Energy and Climate Change (DECC) in 2009, it has delivered £2.6 billion of investment and led to significant savings for consumers. A further £350 million of investment will come through the completion of Tender Round 3. Beyond that, based on offshore wind projects that have already secured subsidy contracts from the Government and those aiming to deliver under the Renewables Obligation scheme, billions more of investment will be required in the coming years.
