Dutch-German Transmission System Operator TenneT, Hitachi Energy, and Petrofac have announced they have entered into early works agreements in support of TenneT’s 2 GW Programme. Under the terms of the agreements, the companies will begin preparatory work and detailed engineering to ensure timely delivery of the first two Dutch offshore converter stations for TenneT’s high voltage direct current (HVDC) offshore wind grid expansion.

Hitachi Energy and Petrofac entered a collaboration in June 2022 to provide joint grid integration and associated infrastructure to foster acceleration of the energy transition. They will deploy their high-voltage direct current (HVDC) and high-voltage alternating current (HVAC) solutions, and Engineering, Procurement, Construction and Installation (EPCI) expertise, in support of the preparatory works.

Marco Kuijpers, Director Offshore at TenneT, said: “The early works agreement with Hitachi Energy and Petrofac is a very important milestone in the execution of our 2GW strategy. With this first agreement we reserve production capacity for platforms and HVDC equipment and initiate the detailed engineering process to secure the time schedule for the 2GW projects IJmuiden Ver Alpha (2029) and Nederwiek 1 (2030). We expect to award the full framework contracts for the HVDC Platform scope of all the 2030 Road Map projects in the first quarter of 2023, also with the other envisaged partners.”

Niklas Persson, Managing Director at Hitachi Energy’s Grid Integration business, said: “We are delighted to deepen our long-standing relationship with TenneT and to help integrate 2 gigawatt systems of much-needed emission-free wind power into the European grid, making it more sustainable, flexible and secure.

“We collaborate with TenneT and Petrofac to co-create innovative and scalable solutions that we can rapidly deploy to accelerate the energy transition.”


Sami Iskander, Petrofac’s Group Chief Executive, added: “TenneT’s 2GW Programme represents a  key step in Europe’s transition to a lower carbon future. Petrofac is very pleased to be deploying its industry-leading offshore wind EPCI expertise, in collaboration with TenneT and Hitachi Energy, as we kick start the first two projects in the programme.”

TenneT stated that it is on course to achieve its 2030 offshore expansion target. Germany, the Netherlands, Denmark, and Belgium have agreed to install at least 65 GW of offshore wind energy together by 2030, announced alongside the inter-governmental Esbjerg Declaration. About 40 GW, almost two-thirds of this is accounted for by TenneT, with 20 GW each in the German and Dutch North Seas. Beyond this, in 2022, Energy Ministers from the members of the North Seas Energy Cooperation (NSEC) and the European Commission announced an increase in their collective ambition in the deployment of offshore renewable energy until 2050.

At present, TenneT's connection capacity is around 7.2 GW in the German North Sea and around 2.8 GW in the Dutch North Sea.


TenneT stated that its innovative 2 GW Programme will provide a blueprint for future offshore grid connection systems and enables faster deployment. The programme aims to see the installation of up to at least six standardised offshore grid connections.
