Hornsea Project One Offshore Wind Farm

31 Mar 2021: update 30/01/2020: Hornsea 1 will receive the CfD price from 31 March 2020 (the remaining 400MW will receive CfD 31 March 2021). Ørsted has proposed the end of March 2021 to trigger the third phase of its CfD agreement, matching the LCCC's TCW Start Date. DONG will be required to have commissioned 80% of its ICE (400MW) for phase three. Note that currently Hornsea Project One is expected to reach full commissioning during the first half of 2020. If this proceeds to be the case, DONG will receive the wholesale market price for electricity for the final 400MW of capacity until the third phase of the CfD agreement is triggered at the Generator's Proposed Start Date. The developer may not propose a start date prior to the TCW Start Date.
