IJmuiden Ver Gamma and Nederwiek I split into smaller sites to reduce financial risks for wind farm developers

At the beginning of September, the sites for the IJmuiden Ver Gamma and Nederwiek I offshore wind farms were split into sites for 1 GW of wind energy capacity. This should reduce the financial risks for wind farm developers applying for a permit. The sites will be connected via two 2 GW offshore stations, Netherlands Enterprise Agency (RVO) released today.

A new permit tender round for the construction and operation of the IJmuiden Ver Gamma and Nederwiek I wind farm sites in the North Sea will start in autumn (Q3) 2025. During the previous tender round for the construction and operation of 2 GW offshore wind farms, RVO received multiple bids from wind farm developers. But there were less than expected. This is partly due to the changed market situation: costs have increased and returns are less certain. That is why the Ministry of Climate and Green Growth is splitting the planned 2 GW sites into 1 GW sites. This means developers need to invest less and the financial risks are reduced.

New sites

The IJmuiden Ver Gamma Site has been split into IJmuiden Ver Gamma-A (eastern site) – 1 GW and IJmuiden Ver Gamma-B (western site) – 1 GW.

Nederwiek Site I has been split into Nederwiek I-A (southern site) – 1 GW and Nederwiek I-B (northern site) – 1 GW.

Two 1 GW wind farms connected to one platform

In total, this still involves 4 GW of offshore wind energy capacity. Grid operator TenneT is installing the offshore grid, which connects the wind farms to the high-voltage grid on land. This is how the wind-generated energy ends up in our electricity grid. The wind farms are connected to a TenneT substation platform for this purpose.

The platforms have a 2 GW high voltage direct current (HVDC) connection to an onshore station. This means that two 1 GW wind farms can be connected to one platform. The HVDC connection ensures that the voltage on the electricity grid remains constant.

Permit application

RVO expects to be able to announce the details of this permit tender round in the 4th quarter of 2024 and expects to publish the exact opening and closing dates at the beginning of 2025. More info can be found on the dedicated website page. Source: RVO
