Details

DESNZ commissioned Arup to undertake this research covering updates to the cost and technical assumptions for offshore wind technologies.

The evidence drawn from research reviews in the generation costs series informs:

• cost estimates and technical assumptions within the generation costs reports
• administrative strike prices (ASPs) analysis for the Contracts for Difference (CfD) renewables deployment scheme
• power sector modelling
