1 Introduction
1.1 E.ON Climate & Renewables UK Rampion Offshore Wind Limited (E.ON) is planning to develop the
Rampion Offshore Wind Farm (the Project) with up to 175 turbines and with an installed capacity
of up to 700 MW. The Project would be located 13 km from the Sussex coast at its nearest point.
The onshore electrical works consist of underground cables running from mean low water east of
Worthing to a new onshore substation adjacent to the National Grid Electricity Transmission plc
(NGET) substation at Bolney in West Sussex and an underground connection between the two
substations.
1.2 As the total installed electricity generating capacity will exceed 100 MW, the Project is deemed to
be a Nationally Significant Infrastructure Project (NSIP), and therefore E.ON is submitting an
application to the Secretary of State under section 37 of the Planning Act 2008 for a Development
Consent Order (DCO) for the construction and operation of the Project.
1.3 This Onshore Substation Design and Access Statement (DAS) has been prepared pursuant to
Regulation 5(2)(q) of the Infrastructure Planning (Applications: Prescribed Forms and Procedures)
Regulations 2009 (the APFP Regulations). Whilst it is not a requirement for a DAS to be
submitted for an offshore wind farm, the DAS has been produced to describe to those examining
the application the physical characteristics of the proposed onshore substation and early
considerations given to the design of, and access to, the substation.
1.4 The DAS provides information available at the time of submission on the following:
Use: What the buildings and spaces will be used for
Amount: How much will be built on the site
Layout: How the buildings and open spaces will be arranged on the site
Scale: How large the buildings and spaces will be
Landscaping: How the open spaces will be designed
Appearance: What the buildings and spaces will look like
Access: How access will be provided.
1.5 The DAS has been prepared in line with national guidance1 on Design and Access Statements.
1.6 The DAS should be read in conjunction with the application plans/drawings referred to in
paragraph 2.1 and also the Environmental Statement (ES) (Document 6.1) submitted with the
application.

Design and Access Statement
Overview
2.1 This section describes the key components of the proposed onshore substation, including details
of the use, amount, scale, layout, landscaping and indicative appearance of the equipment.
Revision A (December 2012) of the DAS presented information considered to be a reasonable
worst case in terms of numbers and types of plant and equipment in the compound and their
physical dimensions. Since this time, electrical detailed design for the substation has been
completed and has resulted in a refined proposal, taking into account discussions with the local
communities around the proposed substation site. Further optimisation of the layout will be
carried out as more information on the site ground conditions becomes available. The indicative
layout of the substation site (which is subject to further optimisation), is shown in Appendix 1 of
this document and the indicative elevations, which have been updated accordingly, are shown in
Appendix 2.
2.2 The proposed substation compound is located to the east of NGET’s existing Bolney substation and
would eventually be owned and operated by an Offshore Transmission Owner (OFTO). The key
components of the compound are: electrical plant (e.g. supergrid transformers, reactive
compensation equipment, filters, switchgear and auxiliary transformers), HV cables, E.ON control
building, OFTO control building, site roads, hardstandings, car parking, fencing and access road.
2.3 The environmental impact assessment (EIA) assumed the worst case in assessing the onshore
substation as part of the overall Project.
Use
2.4 The proposed onshore substation is a key component of the Project and will be required to convert
electricity generated at the offshore wind farm to a higher voltage suitable for onward
transmission to NGET’s electricity transmission system. The proposed onshore substation will be
located in the vicinity of the 400kV National Grid substation at Bolney shown on the Works Plan
(Document 2.5).
2.5 Located in and around the proposed onshore substation site for the Project are three existing
overhead line circuits which help to set a boundary for the development. They consist of the
following:
An 11kV overhead line running north to south through the middle of the site for
supplying nearby farms and local residents, which would need diverting.
To the south of the site, a 132kV overhead line running west to east which is connected
into the existing Bolney 132kV substation by a cable circuit with two 132kV towers
sited just outside the substation site.
To the north of the site, a 400kV overhead line double circuit and single tower
connected into the existing Bolney 400kV substation running west to east. An
underground cable circuit has recently been installed through the site to the east of the
NGET compound and to the west of the 132kV terminal tower located in the west of the
site.
5
2.6 The new onshore substation associated with the Project will be designed to be unmanned during
operation. The site is likely to have a main palisade security fence with an electric pulse fence
installed behind and extending 1m above this fence. CCTV will give remote observation capability
24 hours a day, thus the development will not require day to day access and will not be open to
the public.
Layout
2.7 The worst case indicative layout was derived taking account of the space requirements for each of
the key components of the compound and some site constraints (for example, the overhead lines
at the site). These components are set out below. As detailed above, this indicative layout has
since been refined following completion of the electrical detailed design. Further optimisation of
the layout will be carried out as more information on the site ground conditions becomes
available. The key principles that have been employed to derive the indicative layout (and will be
employed during future layout refinement) are identified as follows:
The design, layout and installation of all plant and equipment within the substation will
allow operation and maintenance in accordance with all relevant statutory requirements
(e.g. the Health and Safety at Work etc Act 1974).
Due to the existing 132kV and 400kV overhead line infrastructure, no operational
equipment will be installed beneath this infrastructure. Fence lines and equipment
adjacent to the overhead lines will observe the minimum clearances to exposed
overhead conductors as set out in the relevant substation design standards
(approximately 5 metres).
As a requirement, based on NGET technical standards, equipment within the substation
will be located a minimum of 3 metres from the fence line for security and safety
reasons.
Heavy equipment (e.g. the super grid transformer, described below) will be located
adjacent to the main access road for ease of installation.
Fire Damage Zones (FDZ) for equipment containing oil will be considered when
producing the layout to ensure there is adequate spacing between substation
components. All equipment located within the substation compound will be positioned
to comply with the appropriate horizontal and vertical design clearances for the
relevant voltage level.
Equipment containing oil will have a bund type foundation with sufficient internal
clearance at ground level between the equipment and the bund wall.
Space is limited within the substation site, so the layout will look to optimise the use of
space in order to minimise the overall substation footprint. This also allows for all
construction areas to be accommodated within the wider substation area.
All electrical plant will be located as close as possible to the NGET substation in order to
minimise connection lengths.
In discussion with E.ON’s independent environmental consultant, RSK, the substation
will be designed to mitigate noise pollution and E.ON will, where possible, seek to
6
locate the largest noise sources away from noise receptors. Noise
mitigation/suppression will be installed where necessary.
Taller structures will be located as far to the west of works plot 25 as possible.
Electrical plant will be located to the west of the existing route of PRoW 8T.
Establish a cut and fill balance on the substation site to establish a substation level
below the current highest level on the site.
Amount and Scale
2.8 The proposed onshore substation will contain a range of electrical equipment, including
transformers, reactive compensation equipment and control buildings (segregated from the High
Voltage (HV) equipment) all located within the substation boundary fence (the compound). It is
anticipated that the substation will take two years to build.
2.9 The majority of the substation equipment is not expected to be taller than 10m (and in most
cases much lower) –the supergrid transformers will include bushings that extend up to 10.5m at
their highest point. The likely maximum dimensions for key equipment within the substation
compound are as follows:
Transformers: 6m wide x 16m long x 10.5m high
Reactors: 4m wide x 7.5m long x 7m high
Filters: 20m wide x 22.5m long x 8m high.
2.10 The maximum height of equipment and buildings is defined within the design parameters of the
draft DCO.
2.11 The proposed substation would be connected to two new 400kV feeder bays to the west of the
existing Bolney substation via underground cabling.
2.12 The current design has allowed for ancillary control buildings to be provided for both E.ON and the
Offshore Transmission Operator (OFTO). These buildings will be single storey (up to 6m high) and
will be segregated from the HV equipment.
2.13 Set out below are more detailed descriptions of the likely appearance and approximate size of
some of the key larger equipment to be installed at the proposed substation.
Supergrid Transformer (SGT)
2.14 The SGTs are used to step up the offshore wind farm transmission voltage to the 400kV required
to export the offshore wind farm power to the transmission system at Bolney substation. The
indicative size of each of the 2 units is 6m by 16m by 10.5m high (to the top of the bushings).
Transformers are typically painted grey. It is noted that the number of supergrid transformers
has been reduced from four (as assessed in the Environmental Statement) to two as a result of
the electrical detailed design, thereby reducing the quantity of the tallest structures within the
substation compound.
Reactive Compensation Equipment
2.15 Reactive compensation equipment is used to condition the wind farm power prior to export to the
transmission system, to ensure it complies with the requirements set out by the transmission
7
system operator. Typically, one set of reactive compensation equipment is required for each
circuit connecting to the transmission system.
2.16 Reactive compensation equipment will typically consist of a SVC unit and separate sets of reactors
and capacitors. The indicative size of the reactive compensation control unit is 4m by 7.5m by
7.1m high. The level of reactive power required from the reactors and capacitors (and therefore
their size) cannot be determined at this early stage, but all equipment will fit within the maximum
dimensions set out in paragraph 2.9.
Harmonic filters
2.17 Harmonic filters are used at the substation to ensure that the power exported to the grid complies
with the quality of supply requirements set out by the transmission system operator. Typically,
one set of harmonic filtering is required for each circuit connecting to the transmission system.
For the illustrative layout at Appendix 1 it has been assumed that each harmonic filter compound
will be of dimensions approximately 22.5m by 20m with an expected height of the filters to be
around 8m.
Circuit Breakers and Busbars
2.18 The electrical busbars are used to connect the various pieces of electrical equipment within the
substation together. Circuit breakers are placed at strategic points within the busbar system in
order to allow sections of the wind farm electrical network to be switched out with minimum
disruption to the wind farm operation.
2.19 The circuit breakers and busbars used for the illustrative substation layout at Appendix 1 have
been based upon air insulated equipment.
Auxiliary Transformers
2.20 In addition to the main SGTs, the substation will also have a set of smaller auxiliary transformers
to provide a low voltage supply to the substation control buildings and auxiliary systems.
Control Buildings and Ancillary Structures
2.21 Within the illustrative substation layout at Appendix 1, separate control buildings have been
provided for E.ON and for the OFTO. These buildings will contain the protection, control and other
equipment required by E.ON and the OFTO to control the wind farm and offshore network
respectively.
2.22 The control buildings will contain a standby control room and permit office as well as mess and
other welfare facilities (e.g. toilets).
2.23 The main E.ON and OFTO substation buildings would have a footprint of approximately 500m2 to
600m2. The buildings would be single storey (up to 6m high). It is noted that this is a revision
from double storey buildings of 12.5m (as assessed in the Environmental Statement) as a result
of the detailed design.
2.24 In addition to the main control buildings, smaller switchroom buildings will be located within the
substation compound adjacent to its associated equipment. These switchroom buildings are
typically 14m by 5m in size.
8
2.25 An underground septic tank would be included on site with dimensions in the order of
approximately 6m by 3m.
2.26 A 120,000 litre water deluge tank has been included within the compound for the purpose of
storing water for use in the event of a substation fire. This would have indicative dimensions of
6.5m wide by 4.5m high.
Appearance
2.27 The appearance of the substation structure primarily derives from its functional need and the
safety requirements of this development. The substation will step-up and transfer the electricity
from the Rampion offshore wind farm. Therefore, the design of the substation is appropriate to
that use. The majority of the structure will be finished in grey shades, or left as material finish,
such as concrete and steel – in keeping with the style of the existing NGET substation at Bolney.
2.28 An application for detailed design approval, including the actual scale of the buildings, will be
submitted to West Sussex County Council prior to construction. However, the draft DCO contains
maximum dimensions in relation to the height of the buildings and equipment within the
substation.
2.29 By using an industrial style design for the structures and including security style fencing it is clear
that this is not a public facility. The indicative site elevations and the structures that exceed the
height of the fencing are required for the operation of the substation, and again derive from the
functional needs of the site. Refined indicative elevations to give an impression of the industrial
style design of the structures are shown at Appendix 2.
2.30 A visible feature of the site will be the security fencing along the external boundary. The
substation will require permanent CCTV equipment and external fencing, to a specified security
standard for this type of installation, to safeguard personnel and prevent unauthorised access.
The site will have a main palisade security fence with an electric pulse fence installed behind and
extending 1m above this fence. Signage in accordance with the Electricity Supply Regulations will
be located in conspicuous positions along this perimeter fence.
2.31 Permanent light fittings will be installed around and within the substation. Under normal
operating conditions the substation will not be illuminated at night. Lighting will be used only
when required for maintenance outages or emergency repairs occurring at night. The lights will
be directed downward, and shielded to reduce glare outside the facility.
Landscaping
2.32 An existing tree and shrub line runs north to south (approximately 200m) and east to west
(approximately 350m). In the design of the substation site, E.ON will seek to retain as much of
both tree and shrub lines as practical. The design of the substation and the protection of trees to
be retained will be in accordance with BS:5837 2012 Trees in Relation to Design, Demolition and
Construction. One tree in the centre of the field will need to be removed. A drainage ditch and
farm track running parallel to the north to south tree and shrub line may also require diverting.
An indicative landscaping strategy, set out in Figure 26.6 in the Environmental Statement
(Document 6.1.26), was developed on the worst case scenario as an integral part of the overall
design of the proposals, the prime objective relating to the onshore substation being to mitigate
9
for the loss of established landscape features caused by the construction of the onshore
substation. This would be achieved through the following:
Targeted planting of trees and shrubs.
Physical and visual integration of the substation into the local landscape pattern, which
would maintain the open aspect and general character of the existing local landscape.
Provision of a degree of visual softening, screening and containment around the final
location of the proposed substation.
2.33 As a result of the completion of the electrical detailed design, the refined substation layout
includes the principle that taller structures will be located as far to the west of works plot 25 as
possible, and electrical plant will be located to the west of the existing route of PRoW 8T.
2.34 The final form of the substation structures will be integrated into the surrounding environment
through the adoption of a robust, sustainable landscape planting strategy. In between the
structures on site permeable areas will be topped with locally sourced stone chippings to promote
natural drainage. Where possible, chippings will be recycled from other applications (such as
railway ballast) and/or sourced locally.
2.35 Prior to construction, E.ON will be required to submit a written landscaping scheme and associated
work programme (in accordance with the principles set out in the Environmental Statement) to
West Sussex County Council for approval.
Landscaping Strategy
2.36 The principles of the landscaping strategy included in the Environmental Statement centre on the
planting of native tree and shrub species, the establishment of which is considered essential in
achieving integration into the wider existing landscape framework.
2.37 The strategy has taken account of species commonly found throughout West Sussex, prevailing
site conditions, and West Sussex County Council land management guidelines and objectives for
the local area.
Indicative Landscaping Proposals
2.38 Indicative landscaping proposals prepared for the onshore substation site and set out in the
Environmental Statement involve the introduction of specimen trees and shrub planting in small
groupings and linear belts within and around the site to reflect existing vegetation patterns
commonly found within the wider landscape.
2.39 Planting will comprise native species, planted as transplants and/or whips, with a concentration of
larger feathered and standard trees (where appropriate) to provide immediate landscape
structure. The use of such planting would also enable achievement of a robust visual screen within
approximately 8-10 years.
2.40 Indicative planting proposals are described below and illustrated on the landscape strategy (Figure
26.6 of the Environmental Statement).
2.41 Planting is proposed along the eastern boundary of the substation site to reinforce the existing
vegetation and contribute to screening views from properties to the east including Coombe Farm.
10
2.42 A large area of planting is proposed to the north of the site; this will assist the visual integration
of the substation and will provide a visual buffer for properties located to the north. Any excess
material from the site could be used to create sensitively profiled earth bunds, in combination with
additional tree and shrub planting, to improve screening of the site particularly along the northern
boundary to the south of the overhead lines.
2.43 Planting will also mitigate and compensate for the loss of existing vegetation within and along the
boundaries of the site.
Landscape Maintenance and Management
2.44 All planting will be implemented, managed and maintained to realise its intended environmental
functions.
2.45 Planted areas will be implemented and managed during the establishment period in accordance
with the landscaping scheme submitted to West Sussex County Council for approval, with
subsequent periodic thinning to retain the desired species balance.
2.46 No tree species will be planted within 6m of the centreline of existing or proposed overhead lines
(in accordance with established guidelines for this type of development); only hedgerow species
will be planted directly below overhead lines to achieve visual screening and integration functions.
2.47 The DCO allows for a maintenance period of 10 years. The reinstatement of all planted areas will
be monitored for a 10 year period from the end of construction. During this time, any plants which
have failed to establish will be replaced and appropriate maintenance (pruning, weeding,
watering, feeding etc.) undertaken.
Access
2.48 Guidance states that the DAS should consider two potential types of access, as follows:
Vehicular and transport links: Why the access points and routes have been chosen,
and how the site responds to road layout and public transport provision. This DAS will
also address additional temporary construction access; and
Inclusive access: How everyone can get to and move through the place on equal
terms regardless of age, disability, ethnicity or social grouping.
Temporary Construction Access
2.49 Given the scale of traffic and the size of some of the loads required during the construction of the
substation, a temporary construction access will be constructed from Wineham Lane across
private land to the substation construction area. This will include a temporary bellmouth slip road
style access point at Wineham Lane sized to facilitate entry of long equipment transportation
vehicles. Shown on Document 2.7 (Access to works plan), this access road would be removed at
the completion of construction and the land returned to its previous use. Construction vehicles will
be restricted to right turns when exiting the site onto Wineham Lane.
2.50 Constructing this temporary access would form part of the substation enabling works which would
last around 4–6 weeks. During this time access would need to be via the existing farm track
(shown on Document 2.7).
11
2.51 This temporary construction access has been proposed following feedback both during informal
landowner negotiations and through the formal consultation process from communities and local
parish councils that main construction traffic should avoid using Bob Lane to access the substation
site.
Operational Access
2.52 During routine operation the largest vehicles accessing the site would be light goods vehicles (e.g.
vans). As such the temporary construction access would be removed and the land reinstated. The
main access to the substation site once it is operational would therefore be via the existing track
located to the east of Twineham Court Farm. The track will be upgraded to ensure it is a suitable
standard for operational traffic. During operation, traffic to the site will be minimal and infrequent.
It would proceed along Wineham Lane from the north, turning left into Bob Lane and finally
turning left again into the access road (shown on Document 2.7).
2.53 Access internally within the substation site will be via 5m wide main roads or 3m secondary roads
where possible.
Access for All
2.54 The substation site will not be open to members of the public and will not have permanent staff on
the site. However, for the purposes of all staff required to go to the site for operational and
maintenance reasons, the relevant legislation and guidance has been considered in relation to
access for all. The Equality Act 2010 has been taken into account. Buildings will be designed and
constructed to ensure that the needs of people with disabilities are accommodated to allow for
access to suitable car parking, office facilities, meeting rooms, mess rooms, washing and toilet
facilities.
Pedestrians and Cyclists
2.55 It is not expected that during operation of the substation any additional traffic caused by the
proposed substation will significantly affect the levels of amenity for cyclists and pedestrians using
surrounding roads. During construction the additional traffic will be subject to a Construction
Traffic Management Plan which would seek to minimise the impact of construction on recreational
users. The requirement for a Construction Traffic Management Plan to be produced is contained
in the draft DCO.
2.56 Footpath No. 8T currently crosses through the footprint of the proposed substation site – E.ON
proposes to permanently close this footpath and provide a permanent alternative routing to the
east of the new substation site shown on Document 2.8 (Footpath stopping up and diversion
plan).
2.57 Access along Footpath No. 1T to the west of the substation which would be crossed by the
temporary construction access is expected to be maintained during construction through a
temporary reroute (see the Public Rights of Way Strategy at Document 8.3).
Public Transport
2.58 The site will not be permanently manned and as such public transport has not been factored into
the design.
12
Conclusion
3.1 The proposed onshore substation site at Bolney is adjacent to the existing NGET Bolney substation
and overhead line infrastructure, has good access from the wider highway network and is well
screened from wider views by the existing vegetation and landscape. More locally additional
planting is proposed to screen the substation from near neighbours. The size of the overall site
also means that it can accommodate a design layout that provides enough space for all
construction lay down and project office accommodation within the site boundary.
3.2 Given the level of existing infrastructure in the local area and the need for a new substation to be
located adjacent to such infrastructure it is felt the location of the proposed development is in
keeping with the existing surroundings and the level of access is suitable for a development of this
type.
