Indicators
- Contract modified due to unforeseen circumstances.
Legal Justification
The contract 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.
