ScottishPower Renewables has awarded an EPCIC (Engineering, Procurement, Construction, Installation and Commissioning) contract for its East Anglia TWO offshore substation and jacket foundation to HSM Offshore Energy. 

HSM Offshore Energy will deliver the 5,100mt offshore high-voltage substation and its 3,700mt jacket foundation for the 960MW windfarm off the coast of Suffolk, which will produce enough clean, green energy to power the equivalent of almost one million homes. 

Initial engineering works for the green energy project got underway in summer 2024 under an early work agreement. Construction is expected to start in Q4 2025, with the jacket ready for installation in Q3 2027 and the topside in late 2027. 

“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.”

The East Anglia TWO offshore windfarm will be located in the southern North Sea approximately 33km from the Suffolk coast at its nearest point off Southwold and 37km to Lowestoft. The project is anticipated to have an operational capacity of up to 960MW, which is enough to power the equivalent of around 950,000 homes.
