OEG wins temporary power contract for Hornsea 3

OEG has secured an agreement to provide temporary power systems for the Hornsea 3 offshore wind farm development in the United Kingdom.

By the CEII Desk, from reporting by Power Technology

Key points

  • OEG will supply generators and fuel tanks for commissioning and turbine installation.
  • The arrangement builds on previous work with Ørsted on Hornsea 1 and 2.
  • Haizea Wind Group delivered monopiles for the project in August 2026.

Contract details

According to Power Technology, OEG has been selected by Ørsted to deliver temporary electricity supply during the setup of the converter station and the installation of turbines at the Hornsea 3 offshore wind development.

The scope of work involves placing generators on a jack-up vessel. This includes a mix of five 200kVA units and two 300kVA units operating together to reach up to 1,400kVA for the offshore converter infrastructure.

Equipment and execution

For the turbine installation phase, the supplier will provide 150kVA generators alongside custom 3,000-litre fuel tanks designed to fit within the limited space on transition pieces.

OEG temporary power technical manager Rob Williams stated in the source report that the firm worked with the construction management team to deliver bespoke technical solutions.

Alida Lewis, head of OEG Temporary Power, noted that the company is expanding its support to cover both the wind turbine generator package and the offshore converter station.

Industry context

The agreement reinforces the ongoing commercial relationship between OEG and Ørsted, following earlier contributions to the Hornsea 1 and Hornsea 2 projects. In August 2026, component manufacturing was advanced when Haizea Wind Group finished delivering monopiles for the 2.9GW facility situated in the North Sea.

Context from CEII

Renewables are the fastest-growing part of the world’s energy system. The COP28 goal is to triple capacity by 2030, and solar mini-grids are the fastest route to power for millions of people without electricity.

27.8% of electricity in the world was renewable in 2021
