1 Introduction
1.1 Overview
1.1.1 This document sets out Forewind‟s proposed scope of works for the Cumulative
Impact Assessment (CIA) for Dogger Bank Creyke Beck onshore works including
transmission and grid connection. The strategy only relates to the onshore
components of Dogger Bank Creyke Beck A and B.
1.2 Background
1.2.1 In June 2008, The Crown Estate announced proposals for the third round (Round 3)
of offshore wind farm leasing, following on from the 8 gigawatts (GW) planned from
earlier United Kingdom (UK) offshore wind leasing programmes (namely, Rounds 1
and 2). Subsequent to this announcement, a Strategic Environmental Assessment
(SEA) to examine the potential for 25GW of additional UK offshore wind was carried
out.
1.2.2 Under the Round 3 process, nine development „zones‟ were identified by The Crown
Estate, with a combined target energy generation capacity of 25GW. On the 8th
January 2010, following a competitive tender process, The Crown Estate announced
the successful bidders for each of the Zones. Forewind Limited (Forewind) was
awarded the development rights for the largest Zone; Dogger Bank. Forewind‟s
commitment is to secure all the necessary consents for the construction and
development of the Dogger Bank Zone.
1.2.3 Forewind has a target to achieve consent for 9GW of projects in the Dogger Bank
zone. Through its ZAP process, Forewind has identified two up to 1.2GW projects
(jointly known as Dogger Bank Creyke Beck) that are expected to be the subject of a
single planning application in 2013.
1.2.4 A grid connection offer was made to connect both projects to the existing National
Grid Electricity Transmission 400kV substation at Creyke Beck, near Cottingham in
the East Riding of Yorkshire.
1.2.5 The main onshore components of Dogger Bank Creyke Beck include:
Joint transition bay – the location where the offshore export cable connects to
the onshore cable system. This is located on the Holderness Coast
(approximately 300m inland) to the north of Ulrome
High Voltage Direct Current onshore cable route (comprising two buried cable
systems) - between the joint transition bay and the onshore converter stations;
Up to two converter stations (one for each project), to convert the High Voltage
Direct Current to High Voltage Alternating Current. The converter stations are
to be located near Cottingham;
DOGGER BANK CREYKE BECK
F-OFC-CH-004 Appendix B Chapter Page 2 © 2013 Forewind
High Voltage Alternating Current cable route (comprising two buried cable
systems) - from the onshore converter stations to the existing National Grid
Electricity Transmission substation at Creyke Beck; and
Possible extension works at the existing Creyke Beck substation – these are
considered at a high level within the Dogger Bank Creyke Beck proposals; a
separate consenting exercise for these possible works will be undertaken by
National Grid at a later date.
1.3 Developing a CIA Strategy
1.3.1 In Advice Note 9 – Using the „Rochdale Envelope‟, the Planning Inspectorate states –
“In assessing cumulative impacts, other major development should be
identified…on the basis of those that are:
under construction;
permitted application(s), but not yet implemented;
submitted application(s) not yet determined;
projects on the Commission‟s Programme of Projects;
identified in the relevant Development Plan (and emerging
Development Plans - with appropriate weight being given as they move
closer to adoption) recognising that much information on any relevant
proposals will be limited; and
sites identified in other policy documents, as development reasonably
likely to come forward.”
1.3.2 It is worth noting that the same advice note also states –
“In preparing such information, it should not be forgotten that the purpose of an
EIA is to inform the decision making process. The EIA should be clear and
practical „so that it assists, and not confuses, the decision making process.”
1.3.3 This appears to be in line with CIA guidance issued by the European Commission in
1999, which stated CIA should cover:
“impacts that result from incremental changes caused by other past, present or
reasonably foreseeable actions together with the project in question”.
1.3.4 Further extracts from relevant guidance include -
“An assessment specific development proposal should be limited to the effects
of the proposal in combination with:
existing development, either built or under construction;
approved development, awaiting implementation; and
proposals awaiting determination within the planning process, and thus
for which design information is in the public domain. Proposals and
design information may be deemed to be in the public domain once an
application has been lodged, and the decision-making authority has
formally registered the application.” (Scottish Natural Heritage, 2005)

“The outermost limit for including projects in a cumulative assessment is
speculative proposals where for example a formal scoping opinion has been
provided and thus the principle of a proposal is within the public domain, and
even then, only on certain occasions. Anything more speculative than that can
at best only be treated as a material consideration, but even then only where
the proposals are in the public domain and "well articulated in terms of location
and scale” (Scottish Natural Heritage, 2005).
1.3.5 The following advice has been considered for geographical and temporal scale
(taken from Hyder (1999) - Guidelines for the Assessment of Indirect and Cumulative
Impacts as well as Impact Interactions - produced for the EC):
1.3.6 Spatial Extent – Geographical boundaries will depend on:
the nature of the project;
the nature of the impacts;
sensitivity of the receiving environment;
availability of data; and
natural boundaries.
1.3.7 Temporal Extent – the guidance states:
“In setting the future time boundary it is suggested that in general, beyond 5
years there is too much uncertainty associated with most development
proposals. It is therefore recommended that in the majority of cases the limit
does not exceed 5 years into the future.”

2 CIA STRATEGY
2.1 Forewind’s approach to onshore CIA
2.1.1 In its simplest form the strategy involves consideration of:
Whether impacts on a receptor can occur on a cumulative basis between the
onshore elements of Dogger Bank Creyke Beck and other activities, projects
and plans for which sufficient information regarding location and scale exist
2.1.2 The strategy recognises that data and information sufficient to undertake an
assessment will not be available for all potential projects, activities, plans and/or
parameters, and seeks to establish the „confidence‟ that can be placed in the data
and information available.
Defining ‘Confidence’ in the context of Forewind’s CIA strategy
2.1.3 A simple „High‟, „Medium‟ „Low‟ and „Very Low‟ ranking scale has been used to
provide an overview of the confidence we have in the data and information that can
be used to underpin impact assessment. The ranking is presented in Table 2.1.
Table 2.1 A ranking scale for assessing confidence in data and information
Data/information confidence
Types of data/information
High Peer reviewed and/or industry standard third party quantitative, semi-quantitative or qualitative data. Forewind‟s own project details and third party project details published in the public domain and confirmed as being „accurate‟ by the developer.
Medium Third party data supplied to or obtained by Forewind that has not been subject to peer review and cannot be quality controlled by Forewind (e.g. survey data from other developers). Third party project details published in the public domain but not confirmed as being „accurate‟.
Low There is a lack of robust data and information and/or data quality is outwith Forewind control. In such cases, precautionary worst cases are likely to be required.
Very Low It is possible that a project/activity/plan could be developed in future, but no details or data is available. In this case, a CIA would not be possible. It would only be possible to appraise the idea that something may happen in the future that could contribute to the overall cumulative impact. In such cases, the data/information should not be used in determining consent for a project.
Onshore CIA process
2.1.4 Using the above approach of assessing data and information confidence will allow
Forewind to undertake the cumulative impact assessment as a two-step process as
follows:

Screening
2.1.5 Individual plans, projects and activities within 10 km1 of the onshore works have been
identified based on information held on the planning portal and identified with relevant
development plans. The list has been appraised, based on the confidence Forewind
has in being able to undertake an assessment from the information and data
available – this exercise is presented in Table 2.2.
2.1.6 Where Forewind is aware that a plan, project or activity could take place in the future,
but has no information on how the plan, project or activity will be executed, it is
proposed that it is screened out of further assessment.
Assessment
2.1.7 All projects, activities and plans with medium to high confidence data and/or project
information are included in the CIA. These are summarised in Table 2.3.
2.1.8 Projects or plans where there is high confidence in data and low confidence in
information of the project/plan (or vice versa) will be considered on a case by case
basis during the screening phase to determine whether confidence is high enough to
include within the assessment and still provide a result which aids the decision
making process.
1 The onshore elements of other offshore wind farms (e.g. Hornsea and Westermost Rough) are beyond 10km from
Dogger Bank Creyke Beck‟s onshore works and are therefore screened out of the onshore CIA. However, these projects are considered in more detail in the offshore CIA.
