Given the combination of the large distance to the coast and the size of the IJmuiden Ver wind energy area, a 2 GW direct current (HVDC) solution, based on 525 kilovolts, appears to offer most economical advantages. It requires only one cable system per 2 GW, limiting the impact on the environment and the surroundings.
To realise such an innovative direct current system, TenneT launched the design phase with five HVDC suppliers on the basis of an innovation partnership: ABB Power Grids, GE Renewable Energy’s Grid Solutions (Netherlands), Consortium 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 this 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.
