NOTICE OF APPLICATION TO MAKE A NON-MATERIAL CHANGE TO THE FOLLOWING

DEVELOPMENT CONSENT ORDER:

THE HORNSEA FOUR OFFSHORE WIND FARM ORDER 2023 (SI 2023/800) AS CORRECTED BY

THE HORNSEA FOUR OFFSHORE WIND FARM (CORRECTION) ORDER 2024 (SI 2024/117)

Notice is hereby given that an application has been made by Orsted Hornsea Project Four Limited (company number 08584182) of 5 Howick Place, London, England, SW1P 1WG (the “Applicant”) to the Secretary of State for Energy Security and Net Zero to make a non-material change to the Hornsea Four Offshore Wind Farm Order 2023 (as corrected by the Hornsea Four Offshore Wind Farm (Correction) Order 2024 the “Order”) under the Planning Act 2008 (the “NMC Application”).

The Order includes provision authorising the construction, operation, maintenance and decommissioning of the Hornsea Project Four offshore wind farm together with associated offshore and onshore infrastructure and all associated development (“Hornsea Four”), on land approximately 69 kilometres from the East Riding of Yorkshire in the Southern North Sea, covering an area of approximately 600 square kilometres. Hornsea Four comprises the following key elements: up to 180 wind turbine generators; offshore transformer substations; offshore convertor substations (High Voltage Direct Current system only); up to one offshore accommodation platform to house operations and maintenance staff; boosters stations (High Voltage Alternating Current system only); subsea inter-array cables linking wind turbines to each other and to offshore substations; subsea interconnector cables linking the offshore substations to one another; subsea export cables to connect the wind farm to landfall; and cable protection.

The Order requires Orsted to construct an artificial nesting structure (“ANS”) for kittiwake, as a compensation measure for the potential impacts of Hornsea Four. Paragraph 3(d) of Part 2 of Schedule 16 of the Order requires the ANS to be in place at least four full breeding seasons before Hornsea Four becomes operational. The NMC Application seeks to make a non-material change to the Order to shorten the length of time the ANS needs to be in place before operation from at least four full breeding seasons to at least two full breeding seasons. The NMC is required to allow time for the construction of the ANS without impacting the programme for the operation of Hornsea Four and its provision of renewable energy to the National Grid. The NMC are needed to ensure that the appropriate and agreed
kittiwake compensation measures are reflected in the Order, in order that construction and implementation of the Order is in accordance with its conditions.

A copy of the NMC Application and its accompanying documents are available for inspection, free of charge, via the Planning Inspectorate’s website at the below address until at least the end of the
consultation period referred to below:
