L&T Secures Landmark ₹150 Billion+ TenneT Offshore Wind Mandate

MUMBAI — Engineering and construction conglomerate Larsen & Toubro Limited (L&T) announced on July 28, 2026, the successful conclusion of an ultra-mega Framework Cooperation Agreement (FCA) with TenneT for its 2 GW High Voltage Direct Current (HVDC) offshore wind programme.

Formally executed in consortium with Hitachi Energy, the framework covers in-principle six offshore wind grid connection projects in the Dutch and German sectors of the North Sea. L&T classified the overall order value as "Ultra-Mega," which denotes contract values exceeding ₹150 billion ($1.8 billion). The contract award marks L&T's largest international clean-energy infrastructure expansion to date, bolstering its clean technology credentials across European energy markets.

Technical Scope and Consortium Project Deliverables

Under the framework arrangement, the L&T and Hitachi Energy consortium will execute four distinct offshore grid connection projects representing a cumulative transmission capacity of 8 gigawatts (GW) operating at 525 kilovolts (kV):

• Ongoing Netherlands Projects: Continued execution of the IJmuiden Ver Alpha and Nederwiek 1 offshore grid connections.

• New Offshore Mandates: Commencement of two new projects Nederwiek 3 in the Netherlands and LanWin 5 in Germany.

L&T will take complete charge of engineering, procurement, construction, and installation (EPCI) for the offshore converter platforms and associated marine civil infrastructure. Hitachi Energy will supply its proprietary HVDC Light® technology for high-efficiency power conversion and transmission from North Sea offshore wind farms to mainland European power grids.

Strategic Significance for European Energy Infrastructure

The North Sea project suite is designed to accelerate Europe’s transition toward decarbonized energy supplies by connecting offshore wind generation directly to domestic consumer and industrial grids.

For stock market participants, energy analysts, and industrial observers, L&T’s selection highlights the global competitiveness of its modular fabrication yards located in Hazira, Kattupalli, and Sohar. By taking over complex platform manufacturing scopes previously assigned to European contractors, L&T secures a multi-year execution pipeline that significantly diversifies its international order book beyond its traditional Middle Eastern market footprint.
