Advice offshore wind tender 2026

Maximum tender amount for the TOWOZ-concept

The Ministry of KGG (Climate and Green Growth) of the Dutch national government has asked the Netherlands Environmental Assessment Agency PBL to give advice on the maximum tender amount to be used in the upcoming wind offshore subsidy tender for the sites Nederwiek 1 and 2, and IJmuiden Ver Gamma. This tender is known as TOWOZ (Tijdelijk Ondersteuningsmechanisme Windenergie Op Zee, which translates to Temporary Support Mechanism Offshore Wind Energy). Our advice includes parameters relating to the revenues of wind offshore, notably the base energy price and the correction amount.

Our advice on the maximum tender amount defines the amount sufficient for the majority of the interested market parties to expect a positive business case. The amount should not be read as the current costs of offshore wind energy. We expect the actual tender bids to be substantially lower than this maximum amount. On the other hand, the bids could also be higher than the expected market value of the electricity produced.
