Preliminary Environmental Information

East Anglia ONE North Limited published the Preliminary Environmental Information Report (PEIR) for the proposed East Anglia ONE North project in accordance with Section 42 of the Planning Act 2008 and presented at Phase 4 Consultation. The documents that comprise this report are available below.

We have supplied guidance documents to support with reviewing the documentation as follows:

Guide to Navigating the Preliminary Environmental Information Report (opens in a new window) - to help readers identify where information on certain topics is located within the PEIR for East Anglia TWO and East Anglia ONE North.
Signposting Document (opens in a new window) - highlights where differences occur between the East Anglia TWO and East Anglia ONE North PEIR Chapters, and therefore directs the reader to those sections of the individual project documentation.

(It should be noted that these documents are intended to serve only as supplementary information to the PEIR and do not form part of the formal package of documentation issued for the Section 42 consultation process.)

Scoping Report

As part of the consenting process we submitted Scoping Reports for East Anglia TWO and East Anglia ONE North to the Planning Inspectorate (PINS) for their consideration in November 2017. These Scoping Reports requested a scoping opinion to agree the methodology for undertaking the full Environmental Impact Assessment (EIA). These assessments form part of the Environmental Statement which will be submitted as part of the full Development Consent application.

The Scoping Reports provided a clear description of our proposed infrastructure, and connection route to the electricity transmission network. The scoping process also sought stakeholder opinions on the areas to be investigated in detail when undertaking our Environmental Impact Assessments.

The Scoping Report for East Anglia ONE North can be viewed on the Planning Inspectorate website here (opens in a new window).
We received the Scoping Opinion from PINS in December 2017. You can view this here (opens in a new window).

East Anglia ONE North Limited (EAONL) have received a Section 105 Notice from Secretary of State requiring the production of a high-level Decommissioning Programme in line with relevant international obligations and compliant with UK legislations and associated consultation process.

The East Anglia ONE North Offshore Wind Farm Order 2022 (2022 Order) granted consent on 31 March 2022 for the development of an offshore windfarm. The consent for East Anglia ONE North has since been amended in December 2022.

The purpose of the Decommissioning Programme is to provide preliminary information on the methods and approaches to how the offshore components will be decommissioned at the end of the operational lifetime of the Project.

The Section 105 Notice requires EAONL to carry out consultation before submitting the Decommissioning Programme to the Secretary of State. This includes carrying out consultation with prescribed bodies and making the proposals publicly available for at least 28 days in order to obtain feedback on the draft Decommissioning Programme.

Therefore, in accordance with the Section 105 Notice, the draft Decommissioning Programme will be made publicly available for 28 days from 19 December 2025 here.

Any enquiries on the documents can be sent to EAONL by email on eastangliaonenorth@scottishpower.com or by post to East Anglia ONE North Decommissioning, 320 St Vincent Street, Glasgow, G2 5AD
