OEG has won a Hornsea 3 temporary power contract from Ørsted for the UK’s 2.9 GW offshore wind project. The scope covers commissioning of the offshore converter station and power supply while turbines are installed and commissioned.

For the converter station work, OEG will place generators on a jack-up vessel. Five units rated at 200 kVA and two rated at 300 kVA will operate synchronously. OEG states that the arrangement will supply the station with up to 1,400 kVA.

The turbine package uses 150 kVA generators coupled with purpose-designed, mountable fuel tanks, each holding 3,000 litres. OEG says the modular arrangement is intended to maximise available power while minimising the space occupied by equipment on transition pieces.

Hornsea 3 is under construction around 120 kilometres from the Norfolk coast in the North Sea, with commissioning planned for 2027. Both offshore converter stations were in place by September 2026. Work to install the project’s 197 monopile foundations started earlier in 2026.

OEG‘s temporary power team also worked on Hornsea 1 and Hornsea 2 during construction and has supported Ørsted projects elsewhere.
