ScottishPower Awards East Anglia TWO Substation Contract to HSM Offshore

ScottishPower Renewables has selected HSM Offshore Energy for a major contract involving the engineering, procurement, construction, installation, and commissioning of the offshore substation and jacket foundation for its 960MW East Anglia TWO wind farm. This renewable energy project is situated in the southern North Sea, approximately 33km off the Suffolk coast near Southwold and 37km from Lowestoft in the UK.


Initial engineering work for this green energy initiative began in the summer of 2024.

The East Anglia TWO wind farm is designed to produce sufficient clean energy to supply power to one million households. HSM Offshore Energy will oversee the construction of the project’s 5,100-tonne offshore high-voltage substation and its 3,700-tonne jacket foundation, key components for the wind farm’s operation.

Hans Leerdam, chief commercial officer at HSM Offshore Energy, commented: “This contract marks an important achievement for HSM Offshore Energy and reinforces our role as a reliable partner in the offshore wind sector. ScottishPower Renewables’ early decision to secure yard capacity highlights the benefits of teamwork and planning ahead in advancing sustainable energy solutions. We are honored to support the East Anglia TWO project and contribute to the UK’s renewable energy goals.”

Engineering efforts for this initiative kicked off in the summer of 2024 through an early work agreement. The construction phase is set to begin in the fourth quarter of 2025, with the jacket foundation installation planned for the third quarter of 2027. The topside installation will follow later that year.

Ross Ovens, managing director for offshore at ScottishPower Renewables, said: “It’s exciting to partner with HSM Offshore Energy to develop our £4bn East Anglia TWO wind farm and boost the UK’s domestic clean energy production. This contract reflects our proactive strategy to lock in top-tier supply chain partners early on, enabling us to start construction later this year with confidence. I’m eager to watch this project come together.”

In a separate agreement, Hitachi Energy was chosen in November 2024 to supply critical grid connection and power quality equipment for the East Anglia TWO project, ensuring its integration into the energy network. This wind farm represents a significant step in expanding renewable energy capacity in the region, supporting broader efforts to enhance sustainable power generation.
