Initially launched on 17 January 2023, the contract underwent modification due to unforeseeable circumstances, including grid connection reforms and elevated development costs. Despite prior publication of competition, the tender was ultimately marked as unsuccessful in the award stage on 29 April 2026. These modifications were necessitated to address changes affecting contract execution without altering the overall concession's nature. This tender offered considerable prospects for businesses involved in offshore wind farm development, particularly those skilled in addressing logistical and technical challenges associated with grid connectivity and equipment procurement. Companies with expertise in adapting to dynamic project requirements and navigating regulatory landscapes would have had significant opportunities for growth in this sector. Despite the unsuccessful award status, the procurement process highlights the potential for continued investment and innovation in renewable energy projects by The Crown Estate. ## Notice This notice is being published on a voluntary basis as no new contract is being awarded. This notice relates to the modification of a concession contract for the award of seabed rights for the development, construction and operation of an offshore wind farm which was entered into by The Crown Estate and GT R4 Limited on 17 January 2023, following the completion of The Crown Estate's Offshore Wind Leasing Round 4 process. ### Lot Information Lot 1 NO NEW CONTRACT IS BEING AWARDED. For the avoidance of doubt, this notice is being published on a voluntary basis as no new contract is being awarded. This notice relates to the modification of a concession contract for the award of seabed rights for the development, construction and operation of an offshore wind farm which was entered into by The Crown Estate and GT R4 Limited on 17 January 2023, following the completion of The Crown Estate's Offshore Wind Leasing Round 4 process. The modifications to the contract which are the subject of this notice are that for a period up to the expiration of the option in the Agreement for Lease, (i) developers will pay pro rata monthly, rather than annual, option fee payments with a balancing payment due on completion of the Lease pursuant to the Agreement for Lease. That balancing payment will be equal to the annual Option Fee which would have been payable in respect of the relevant year less the monthly payments actually made in that year; and (ii) the Agreement for Lease may be terminated without payment of the break payment, and with no Option Fee balancing payment. The Crown Estate considers that these changes are required due to circumstances which it was not possible to foresee at the time of the original award. The contract therefore needs to be modified due to circumstances which The Crown Estate could not have foreseen and is being modified in accordance with the requirements of regulation 43(1)(c) of the Concession Contracts Regulations 2016. The modifications were made necessary by the following unforeseeable circumstances: (a) Grid connection reforms that required late location changes to grid connection and cable routing requiring significant new work and upfront cost. (b) Elevated development expenditure beyond normal market expectation, arising from factors including grid delays, late changes to cable routes, and site investigation cost increases. (c) The significant increase in main equipment package procurement lead times, resulting from factors including supply chain pressures, deterioration of supplier risk appetite, and contraction of Wind Turbine Generator (WTG) Original Equipment Manufacturer (OEM) market. The first limb of the unforeseeable circumstances test is therefore met. The second limb of the unforeseeable circumstances test is satisfied as there is no alteration to the overall nature of the contract, which will remain a public services concession. The object and purpose of the contract will remain the same under the modifications. The third limb of the unforeseeable circumstances test is also satisfied as the modifications will not exceed 50% of the value of the original concession contract ## Key Details | Field | Value | | --- | --- | | Publication source | Find A Tender Service | | Latest notice | https://www.find-tender.service.gov.uk/Notice/039054-2026 | | Notice type | Award Notice | | Procurement type | Standard | | Procurement category | Services | | Procurement method | Not Specified | | Procurement method details | Award procedure with prior publication of a call for competition | | Tender suitability | Not specified | | Awardee scale | Not specified | | All stages | Award | ## Dates | Field | Value | | --- | --- | | Publication date | 29 Apr 2026 | | Submission deadline | Not specified | | Future notice date | Not specified | | Award date | 29 Apr 2026 | | Contract period | Not specified | | Recurrence | Not specified | ## Values | Field | Value | | --- | --- | | Tender value | Not specified | | Lots value | Not specified | | Awards value | Not specified | | Contracts value | Not specified | ## Status | Field | Value | | --- | --- | | Tender status | Unsuccessful | | Lots status | Cancelled | | Awards status | Unsuccessful | | Contracts status | Not specified | ## Buyer | Field | Value | | --- | --- | | Main buyer | THE CROWN ESTATE | | Locality | LONDON | | Post town | South West London | | Postcode | SW1Y 4AH | | Country | England | | ITL 1 | TLI London | | ITL 2 | TLI3 Inner London - West | | ITL 3 | TLI35 Westminster and City of London | | Local authority | Westminster | | Electoral ward | St James's | | Westminster constituency | Cities of London and Westminster | | Delivery location | Not specified | ## CPV Codes ### Divisions - 09 - Petroleum products, fuel, electricity and other sources of energy - 31 - Electrical machinery, apparatus, equipment and consumables; lighting - 76 - Services related to the oil and gas industry ### Codes - 09300000 - Electricity, heating, solar and nuclear energy - 09310000 - Electricity - 31121320 - Wind turbines - 76521000 - Offshore installation services ## Release History - 29 Apr 2026 at 10:12 - Award - Award Notice - https://www.find-tender.service.gov.uk/Notice/039054-2026 ## Notice URLs - https://ted.europa.eu/udl?uri=TED:NOTICE:488882-2019:TEXT:EN:HTML - https://www.thecrownestate.co.uk/ ## Provenance This Markdown file is an alternate public rendering of the D3 Tenders contract record.
