Larsen & Toubro (L&T) and Hitachi Energy have entered into a Framework Cooperation Agreement with Dutch-German grid operator TenneT, covering a series of high-voltage direct current (HVDC) connections for offshore wind farms in the North Sea. The companies announced the deal on 28 July 2026, calling it an "Ultra-Mega" agreement.
The framework covers six projects in principle, with the potential for further work under TenneT's 2 GW HVDC initiative. Four projects have been named so far: IJmuiden Ver Alpha and Nederwiek 1 in the Netherlands, Nederwiek 3 also in the Netherlands, and LanWin 5 in Germany. Together, these four links will have a combined transmission capacity of 8 GW at a voltage of 525 kV.
Under the division of responsibilities, L&T will oversee the engineering, procurement, construction, and installation (EPCI) of offshore converter platforms and associated infrastructure. Hitachi Energy will supply its HVDC Light technology for power conversion and transmission, a key component in enabling efficient long-distance submarine power transfer.
The order value exceeds ₹15,000 crore (approximately $1.8 billion), a figure that L&T classifies as "Ultra-Mega", a designation the company reserves for its largest contracts. The agreement positions the consortium as a major player in Europe's energy transition, as TenneT expands its offshore grid to integrate growing wind capacity.
L&T's offshore wind vertical will draw on engineering talent from its centres of excellence in India and Sharjah, UAE, and will utilise modular fabrication facilities in Kattupalli, India, to deliver the projects. This infrastructure supports the large-scale manufacturing and assembly required for the converter platforms.
The framework agreement is part of TenneT's broader program to build a robust offshore grid in the North Sea, which is central to Europe's renewable energy goals. The projects will enable the connection of wind farms to onshore grids, facilitating the transmission of clean energy to consumers.
While the agreement is a significant step, the companies have not disclosed a detailed timeline for the projects. The framework provides a structure for future contracts, with specific orders expected to follow as TenneT finalizes its project pipeline.
