Consultations and AR4 contract documents

Ahead of AR4, the government ran 4 consultations on amendments to the CfD scheme. These covered a wide range of proposals, including:

  • introduction of a third, offshore wind-only pot
  • introduction of a separate definition and administrative strike price for floating offshore wind projects
  • changes to the Supply Chain Plan process
  • changes to the CfD contract to implement policy changes and reflect the UK’s departure from the EU

The final revised Standard Terms and Conditions and Generic Agreement documents are available here. They reflect the changes made to the CfD contract from AR4 onwards.
