Ofgem tenders OFTO for the Burbo Bank Extension project

Ofgem, the government regulator for gas and electricity markets in Great Britain, has launched a tender process to appoint an Offshore Transmission Owner (OFTO) for the Burbo Bank Extension (BBW02) Offshore Wind Farm.

The BBW02 will be situated in the Bay of Liverpool approximately 20 kilometres off the coast of Liverpool, and will be located entirely within UK territorial waters. National Grid Electricity Transmission PLC (NGET) is the onshore transmission licensee, and the BBW02's transmission assets will connect to the Bodelwyddan, 400 kilo volt substation, North Wales.

The BBW02 Offshore Wind Farm will be the first commercial UK wind farm to utilise 8 MW wind turbine generators (WTGs) and will consist of 32 8MW WTGs with a Transmission Entry Capacity (TEC)1 of 254.2 MW, which will be connected to an offshore substation platform (OSS) located within the boundaries of the BBW02 Offshore Wind Farm2.

The BBW02 Transmission Assets are currently under construction and due to be fully operational and commissioned by the end of Q3 2016. They will include an onshore substation, an OSS one subsea cable and one land cable, and an OFTO dedicated Supervisory Control and Data Acquisition (SCADA) system.

The first stage of the tender exercise to appoint an OFTO for the BBW02 is an enhanced pre-qualification (EPQ) stage. Bidders should demonstrate that they are qualified for financing, operating and managing offshore transmission assets. The deadline to submit the solicited documents is June 6.
