Hitachi Energy and Larsen & Toubro (L&T) announced that they have received the award of Nederwiek3 and LanWin5, the third and fourth projects under their previously announced multi-year framework agreement with TenneT. Hitachi Energy is an electrification company and Larsen is an Indian multinational known for its engineering, procurement and construction (EPC), manufacturing and services.

The award is significant as Europe enters the electricity era and demand for clean power is accelerating across industry, transportation, and digital infrastructure. This makes the expansion of grid capacity a critical enabler of energy security, economic growth, and societal progress, Hitachi said. 

Hitachi and L&T are already collaborating to deliver Nederwiek1 and IJmuiden Ver Alpha. This announcement further strengthens the partnership through Nederwiek3 and LanWin5, HVDC links that will each transmit 2 gigawatts (GW) of renewables from the North Sea to shore, enabling the integration of offshore wind power into the national grids of the Netherlands and Germany, respectively, Hitachi said.

Under the terms of the partnership, Nederwiek3 will connect to an onshore converter station in the municipality of Geertruidenberg in the south of the Netherlands, while LanWin5 will deliver clean power from the North Sea to Lower Saxony in Germany. The goal is for the two links to jointly deliver 4 GW of clean electricity to the grid – enough to power the equivalent of around 4 million households while strengthening energy security and enhancing grid reliability.

As part of TenneT’s landmark 2 GW Program, the projects exemplify the shift from standalone connections to a more interconnected, flexible grid architecture, laying the foundation for a resilient European power system, according to Hitachi. They are designed as part of the broader evolution toward an increasingly interconnected European grid, with future interconnections already embedded in their design. A key target is the integration of Nederwiek3 to the British grid through the LionLink interconnector, currently under development, creating a truly multipurpose interconnector that strengthens links between European and UK energy markets while unlocking the full potential of the North Sea as a renewable energy powerhouse.

The vision is for the links to evolve over time into multi-terminal hubs, enabling a more efficient use of existing infrastructure for future connections and supporting the development of a more flexible, resilient, and integrated power network. This concept has already been demonstrated in the UK through the 1,200 MW Caithness Moray Shetland project, Europe’s first multi-terminal HVDC VSC interconnection, which marked a significant step toward a future grid of energy superhighways and hubs capable of integrating more clean power, optimizing grid assets, improving AC grid performance, and enhancing overall system resilience.

“As a pioneering technology and market leader, we are delighted to deliver our HVDC technology for Nederwiek3 and LanWin5, combining world-class energy and digital systems, said Niklas Persson, CEO of the grid integration business unit at Hitachi Energy. “Our strong collaboration with L&T, built on an agile business model, scalable solutions, and synergies among projects, enables us to support TenneT in accelerating offshore wind deployment in the North Sea and Europe’s ambition to become the world’s first climate-neutral continent.”

S. N. Subrahmanyan, chairman and managing director of L&T, said the agreement with TenneT marks a significant milestone in the company’s journey to provide sustainable infrastructure and clean energy systems. “As nations accelerate their transition toward a low-carbon future, the development of robust offshore transmission networks will be critical to integrating renewable energy at scale,’’ Subrahmanyan said.
