## Standardized 525 kV HVDC Modular Converter Platforms

The multi-billion-euro agreements cover the complete engineering, procurement, and fabrication of two identical 2 GW standardized offshore converter stations and their onshore grid-tie counterparts.

Each offshore platform will deploy Hitachi Energy’s high-power Voltage Source Converters (VSC) and 525 kV gas-insulated DC switchgear, while L&T will fabricate the 30,000-tonne topside and jacket structures at its Hazira yard.

## Harmonizing North Sea Supply Chains

By standardizing equipment designs across Dutch and German territorial waters, TenneT reduces delivery lead times by 18 months and establishes mutual spare-part interchangeability.

LanWin 5 and Nederwiek 3 are scheduled for grid energization in 2030 and 2031, directly supporting the Esbjerg and Ostend intergovernmental North Sea energy declarations.
