ScottishPower Renewables has awarded an EPCIC (Engineering, Procurement, Construction, Installation, and Commissioning) contract to HSM Offshore Energy for the offshore substation and jacket foundation of its East Anglia TWO wind farm. The high-voltage substation will weigh around 5,100 tonnes, with its supporting jacket foundation adding another 3,700 tonnes. This offshore hub will gather electricity from the wind turbines, step up the voltage, and transmit it via subsea cables to the onshore grid.
Construction is scheduled to begin in Q4 2025. The jacket foundation is expected to be installed by Q3 2027, followed by the substation topside by the end of that year.
Located in the southern North Sea, the 960 MW East Anglia TWO wind farm will sit approximately 33 km off the Suffolk coast, near Southwold, and 37 km from Lowestoft, where ScottishPower’s offshore wind operations and maintenance base is located. Once operational, the project will generate enough clean electricity to power nearly one million homes.
“This contract represents a significant milestone for HSM Offshore Energy and underscores our position as a trusted partner in the offshore wind industry. The proactive approach taken by ScottishPower Renewables to reserve yard capacity early demonstrates the value of collaboration and forward-thinking in driving the energy transition. We are proud to contribute to the East Anglia TWO project and to play a role in supporting the UK’s ambitious renewable energy targets,” said Hans Leerdam, CCO at HSM Offshore Energy.
Ross Ovens, ScottishPower Renewables’ Managing Director for Offshore, said: “It’s fantastic to be working with HSM Offshore Energy to bring our £4 billion East Anglia TWO windfarm to life and produce more homegrown green generation for the UK. This contract is a great example of the innovative and forward-thinking approach we took to securing quality supply chain partners for the project at the earliest opportunity and means we can hit the ground running to begin construction later this year. I can’t wait to see the project take shape.”
