Hitachi Energy, Petrofrac secure “landmark” offshore wind agreement from TenneT

(WO) — Hitachi Energy and Petrofac have been selected by TenneT, the Dutch-German transmission system operator, to supply multiple offshore and onshore HVDC converter stations and associated infrastructure to accelerate the integration of bulk renewables into European power grids.

Hitachi Energy and Petrofac were awarded the multi-year framework agreement as part of TenneT’s ambitious offshore wind "2GW Program”1, based on high-voltage direct current (HVDC) technology pioneered by Hitachi Energy.

The agreement includes an initial commitment to deploy six record-breaking renewable integration systems, five of which will connect offshore wind farms to the Dutch grid and the sixth to the German grid. Each of these connection systems has a capacity of 2 gigawatts (GW) and a voltage level of 525 kilovolts (kV) - a world-first for offshore wind.

This landmark framework agreement is the largest ever for Hitachi Energy. The framework agreement approach allows Hitachi Energy and Petrofac to plan in advance and increase their workforce and manufacturing capacity timely as well as train people to have the skills needed in the industry while also capturing synergies between successive projects to meet the in-service dates. 

Hitachi Energy will supply its HVDC Light converter stations, which convert AC to DC power offshore and DC to AC onshore. Petrofac will undertake the engineering, procurement, construction and installation (EPCI) of the offshore platforms and elements of the onshore converter stations.

The first contract under the framework, for the Ijmuiden Ver Alpha project, was awarded with immediate effect. The second, Nederwiek 1, is expected to be awarded later in the year. The framework also includes projects Doordewind 1, Doordewind 2, Nederwiek 3 and LanWin5, expected to be awarded over a 2024-2026 timeframe.

“This innovative business model will set the course for the integration of a huge amount of offshore wind power and gives visibility of the future.  In fact, we are already hiring to expand our global delivery capacity and effectively fulfill these and other orders,” said Niklas Persson, Managing Director at Hitachi Energy’s Grid Integration business.

“We have already secured key resource and the yard capacity required to expedite the first two projects in TenneT’s ground-breaking program,” said Sami Iskander, Petrofac’s Group Chief Executive. “By combining Petrofac’s industry-leading EPCI expertise and Hitachi Energy’s well proven technology, we look forward to supporting TenneT to connect larger, more effective wind farms to deliver affordable clean energy for millions of European homes.”

“TenneT has the technical know-how, scale, and geographical position to connect wind energy from the North Sea. This is one of the most important infrastructure projects of the century; the green transformation of the energy system is key for the decarbonisation of industry,” said Tim Meyerjürgens, COO of TenneT.

Hitachi Energy and Petrofac began working together in June 2022, to provide joint grid integration and associated infrastructure solutions to support TenneT’s 2GW Program.2

In the same year, Germany, the Netherlands, Denmark and Belgium agreed to install at least 65 gigawatts of offshore wind energy combined by 2030 announced with the inter-governmental Esbjerg Declaration.3 At 40 gigawatts, almost two-thirds of this capacity is accounted for by TenneT, with 20 gigawatts each in the German and Dutch North Sea sectors.
