AFRY was commissioned by the Dutch Ministry of Economic Affairs and Climate Policy to deliver a market study supporting government decision-making on the tender procedures for the IJmuiden Ver Gamma offshore wind area and the Nederwiek I offshore wind area. The work focused on identifying and analysing key uncertainties and risks affecting the offshore wind business case in the Netherlands and on evaluating how tender design could be adjusted to improve investability and participation. AFRY’s scope included interviews with Dutch and international industry stakeholders and a quantitative assessment of sensitivities impacting offshore wind economics, including effects on levelised cost of electricity (LCOE) and revenue assumptions. The study also benchmarked Dutch tender approaches against other European markets (Denmark, Germany, and Great Britain) and developed a set of recommendations intended to reduce risk and improve bidder confidence. Recommendations referenced in the study included measures related to build time flexibility after award, standardisation considerations (including turbine size), and the feasibility of reducing tendered site sizes to 1 GW. This advisory work supported the Ministry’s preparation of the permit/tender framework relevant to the IJmuiden Ver Gamma area, which subsequently underpinned the 1 GW Gamma-A and 1 GW Gamma-B site tender approach. The role was performed at the development stage, ahead of project award and procurement of construction packages.
