Tennet will build two 2 GW offshore grid connections in the IJmuiden Ver wind energy area, something it has never used before. To ensure this innovative requirement can be achieved, TenneT has entered into a so-called ‘innovation partnership’ with HVDC suppliers.

The innovation partnership is a tendering procedure in which TenneT, as contracting authority, can start a development process together with suppliers and then proceed to purchase the solution that is not yet available on the market. The partners will help design a standardised new platform and a high voltage direct current (HVDC) transmission system which can be used for the IJmuiden Ver Alpha and Beta connections (due in 2030) but also other future 2 GW high voltage connections like planned in Germany.

The partnership includes the following participants: ABB Power Grids, GE Renewable Energy’s Grid Solutions (Netherlands), a consortium of Global Energy Interconnection Research Institute Co. Ltd. (GEIRI) & C-EPRI Electric Power Engineering Co. Ltd. (C-EPRI) (China), Siemens (Germany), and Xian Electric Engineering Co., Ltd (China). These suppliers will develop an innovative 2 GW 525 kV HVDC solution based on criteria set by TenneT.

They will provide specific information on this to Iv-Offshore&Energy b.v., which is carrying out the Front-End Engineering Design (FEED) study on behalf of TenneT. On this basis, a standardised platform design will be developed for all HVDC solutions.
