Larsen & Toubro (L&T)

India-based Larsen & Toubro (L&T) was confirmed on 31 October 2025 as the replacement for Petrofac within TenneT's 2 GW offshore HVDC programme, partnering with Hitachi Energy to deliver HVDC offshore converter platforms and onshore converter stations across the Dutch portfolio of 2 GW grid connections. The portfolio includes the Doordewind 1 link from the Doordewind I wind farm zone to Eemshaven Oudeschip (380 kV), alongside IJmuiden Ver Alpha, Nederwiek 1, Nederwiek 3, Doordewind 2 and the German LanWin5 connection. The substitution followed TenneT's termination of part of Petrofac's scope under the original March 2023 EUR 13 billion framework agreement, after Petrofac was unable to meet its contractual obligations and entered administration. Under the revised arrangement Hitachi Energy retains the HVDC technology supply (VSC converters, valves, transformers, controls) while L&T inherits the EPCI / installation responsibilities — offshore platform fabrication, onshore converter station construction, and offshore/onshore installation works — previously assigned to Petrofac. For Doordewind 1 specifically, this covers the 2 GW, 525 kV bipolar HVDC offshore converter platform installed in the Doordewind wind energy area and the matching onshore converter station near the 380 kV Eemshaven Oudeschip substation. No project-specific contract value or delivery milestone was disclosed; commissioning of the Doordewind 1 link is currently planned for around 2032–2033 in line with TenneT's published programme schedule.
