PLANNING (CHANGES TO, AND REVOCATION OF, DEVELOPMENT CONSENT ORDERS)
REGULATIONS 2011

NOTICE OF APPLICATION TO MAKE A NON-MATERIAL CHANGE TO THE FOLLOWING
DEVELOPMENT CONSENT ORDER:

THE HORNSEA PROJECT THREE OFFSHORE WIND FARM ORDER 2020 (SI 2020/1656) AS
CORRECTED BY THE HORNSEA THREE OFFSHORE WIND FARM (CORRECTION) ORDER 2021
(SI 2021/599)

Notice is hereby given that an application has been made by Orsted Hornsea Project Three (UK) Limited
(company number 08584210) of 5 Howick Place, London, England, SW1P 1WG (the “Applicant”) to
the Secretary of State for Business, Energy and Industrial Strategy to make a non-material change to
the Hornsea Project Three Offshore Wind Farm Order 2020 (as corrected by the Hornsea Three
Offshore Wind Farm (Correction) Order 2021) (the “Order”) under the Planning Act 2008 (the “NMC
Application”).

The Order includes provision authorising the acquisition for the purpose of the construction, operation,
maintenance and decommissioning of the Hornsea Project Three offshore wind farm together with
associated offshore and onshore infrastructure and all associated development (“Hornsea Three”), on
land within the former Hornsea Zone in the North Sea approximately 121 kilometres to the northeast of
the north Norfolk coast and approximately 10 kilometres west of the median line between UK and
Netherland waters covering an area of approximately 696 square kilometres. Hornsea Three comprises
the following elements: up to 231 wind turbines; up to three offshore accommodation platforms; up to
twelve offshore transformer substations; up to six subsea offshore High Voltage Alternating Current
(“HVAC”) booster stations; up to four surface offshore HVAC booster stations; subsea inter-array
electrical circuits; a marine connection to shore; a foreshore connection and an onshore connection
(comprising up to six export cable circuits and other associated infrastructure) to an onshore substation
(which could also include an onshore HVAC booster station sited along the route); and the connection
from there to National Grid’s existing Norwich Main substation.

The Order requires the Applicant to construct four artificial nesting structures (“ANS”) for kittiwake along
the English east coast, as a compensation measure for the potential impacts of the Hornsea Project
Three Offshore Windfarm (“Hornsea Three”). Paragraph 3(c) of Part 1 of Schedule 14 of the Order
requires four structures to be in place to allow four full kittiwake breeding seasons to elapse before
Hornsea Three becomes operational. The NMC Application seeks to make a non-material change to
the Order to shorten the length of time the ANS need to be in place before Hornsea Three becomes
operational. Specifically, a change from four breeding seasons to three breeding seasons for two
structures and two breeding seasons for the other two structures has been requested.
