1 INTRODUCTION

1.1 Background

1.1.1 This document ‘Design Principles Statement’ is to be read in conjunction with the Design and Access Statement (Document 10.2) (DAS) and Interim Landscape Mitigation Strategy (document 10.6) (LMS) prepared as part of the Progress Power Ltd Development Consent Order (DCO) application documentation, and submitted to PINS for examination in order to demonstrate compliance with National Policy Statements (NPSs).

1.1.2 It provides clarification of design guidelines for the Power Generation Plant and Above Ground Installation (AGI) located on land within the former Eye airfield and Electrical Connection Compound located on farmland to the west of the A140. The principles contained in this document have been agreed with Suffolk County Council and Mid Suffolk District Council.

1.1.3 The purpose of this document is to contribute to early engagement with the parties involved in the detailed design process of the Power Generation Plant, AGI and the Electrical Connection Compound, and in particular to describe a set of outline design principles in order to support the discharge of Requirement 3 of the draft DCO.

1.2 Detailed Design Approval

1.3 Site Location and Proposed Development

1.3.1 The Project consists of three main elements: the Power Generation Plant, the Gas Connection, and the Electrical Connection.

1.3.2 The Power Generation Plant will be situated on land within the former Eye Airfield, approximately 1 km north west of Eye, 1.3 km west of Langdon Green, approximately 1.5 km east of Yaxley, in Mid Suffolk, and 4 km south of Diss in South Norfolk. The approximate Grid Reference of the Power Generation Plant Site is TM 132 750. The Power Generation Plant Site will be located on land which makes up part of the former World War 2 airfield. The location of the Project Site is shown in Figure 1. Z

1.3.3 The Power Generation Plant Site, which is within the Project Site, covers an area of approximately 10 ha. However, the footprint of the Power Generation Plant will be smaller than the full Power Generation Plant Site. Doc. 2.4 Indicative Site Plans, Figure 1: Site Plan Power Generation Plant shows the position of the Power Generator Plant within this part of the Project Site. Construction of the Power Generation Plant will require an area for equipment / material laydown which will allow for the storage of construction materials and provide an area for the assembly of large plant items within a reasonable distance of the construction site. Once operational, this area will be used for maintenance activities, though will be landscaped in accordance with the Outline Landscaping Plans. The Power Generation Plant laydown and maintenance area to the south of the Power Generation Plant has been identified for this purpose (Figure 2).

1.3.4 The Gas Connection Route Corridor will run to the Power Generation Plant from Feeder 5 on the National Transmission System (NTS). The route of the Pipeline will follow a northerly direction, for an approximate length of 1.5 km. From the NTS a new AGI will be constructed, from which the Gas Connection will follow to the north of Castleton Way, it will follow field boundaries to the north and will cross Potash Lane (the former airfield runway) to enter the Power Generation Plant Site at its southern end. Construction and maintenance access to the AGI will be via a new access off Potash Lane.

1.3.5 The Electrical Connection will consist of a new underground cable circuit which will connect the Power Generation Plant into the existing 400 kV electrical infrastructure via a new substation within the Electrical Connection Compound (consisting of a new Substation and Sealing End Compound) that will be located adjacent to the existing overhead line. The Electrical Connection Route Corridor will exit the Power Generation Plant Site to the south where it will cross Potash Lane and follow the northern field boundary south of the Speed Deck factory before crossing


the A140 (by Horizontally Directional Drilling) and re-emerging within the agricultural fields on the west side of the A140. The Electrical Connection Route Corridor will then cross the fields for the cable to terminate at the new Electrical Connection Compound Site, located to the south of The Leys. A new permanent Access Road will be constructed across the agricultural fields to allow construction and maintenance access to the Electrical Connection Compound. This road will follow the line of the Electrical Connection Route Corridor to reduce environmental impacts as much as possible and will connect to the A140 via a new A140 Junction during the construction phase, after which the junction with be removed and the road reinstated as per specifications to be agreed with the local highway authority.

2 DESIGN CONSIDERATIONS

2.1 Guidance Documents

2.1.1 The DAS submitted with the DCO application in March 2014, has been informed by relevant guidance including CABE’s guidelines ‘A Design-led Approach to Infrastructure’, and the findings of the Environmental Impact Assessment – in particular the landscape and visual impact assessment (refer to document 6.2, Environmental Statement section 11).

2.1.2 This document takes into consideration all the documents noted above.

2.2 Additional Design Considerations

2.2.1 The MSDC Eye Airfield Planning Position Statement (Non-Statutory Planning Guidance) adopted 18th November 2013 (EAPPS) confirmed the Council’s decision that the Eye Airfield Development Framework (Feb 2013) (EADF) should guide future development on the airfield for both employment and housing on an interim basis.

2.2.2 The Position Statement explains the context and neighbouring uses of the site and describes the findings of baseline studies and consultation exercises. The constraints posed by the existing Gas Compressor Station, in the centre of the Eye Airfield, are also explained. This has Health and Safety (HSE) enforced consultation zones (an Inner Zone and a Middle Zone) which limit high density uses or sleeping accommodation within the Inner Zone. Development is also prohibited on land covering or closely adjacent to the NTS pipelines that deliver gas to and from the Gas Compressor Station. The Power Generation Plant Site is identified on Map 4 of the Position Statement as ‘Potential Infill Area – ‘safeguarded’ for ‘Energy Park that may include (a) Nationally Significant Infrastructure Project (NSIP) (Gas-fired Power Station and/or


(b) SCC Waste Core Strategy EFW [Energy from Waste] site’, the former in recognition of the emerging Progress Power proposals.

2.2.3 Section 5.2 of the Position Statement recognises that the airfield site is predominantly countryside with an agricultural character, which is an important part of the setting for Eye and surrounding villages. The EADF adopts a landscape led approach. For the site of the proposed Power Generation Plant (Area 8 shown on the indicative masterplan) the EADF suggests that landscape treatment should take the exemplar of the Gas Compressor screening with a view to extending this to form a new countryside edge pending future development in the South Western Zone and an appropriate setting for higher value uses when this zone is developed.

3 DESIGN PRINCIPLES AND RECOMMENDATIONS

3.1 Good Design

3.1.1 As stated in the National Policy Statement EN-1, ‘good design is also a means by which impacts can be mitigated’. The proposed Gas Fired Power Station and associated development at Eye is likely to have some residual impact and therefore the design, materials and massing of the proposed buildings, as well as mitigation measures, must demonstrate good design in respect of landscape and visual amenity.

3.2 Appearance and Design Principles

3.2.1 Table 3 outlines the specific design principles PPL propose to carry forward through discharge of the Requirements within the Draft Development Consent Order. They have been refined in consultation with Suffolk County Council and Mid Suffolk District Council, during the Examination period of the PPL DCO.

Table 3: Design Principles

General Design Principles

1 PPL is committed to engagement with Parish Councils, local residents, Mid Suffolk District Council and Suffolk County Council on detailed design and landscaping. This engagement could include up to two workshops, jointly hosted by PPL and the District Council, and facilitated by an independent design professional. The first workshop, to be held on appointment of the preferred contractor, would develop the understanding of local expectations for the quality and character of the new development. The second workshop would consider draft detailed designs for each of the component parts of the development. This workshop


would be undertaken prior to the application to discharge the DCO Requirements for detailed design (Requirements 3 and 4).

2 The proposed buildings, structures and perimeter security fencing shall be of high quality design.

3 Materials used for cladding shall above all be durable and functional for operation for 25yrs in a power station / electrical substation environment.

4 The architectural design, use of recessive colours of the buildings, and structures shall be designed to reduce visual impact and assimilate the Project into the surrounding landscape.

Power Generation Plant Design Principles

5 Siting of structures within the Power Generation Plant will be substantially in accordance with Figure 1 of document 2.4 Indicative Site Layout Plan.

6 The gas turbines will be located in the north of the Power Generation Plant Site, so as to maximise the screening provided by existing warehouse buildings to the west, the Eye Chicken Litter Power Plant to the north and the National Grid Gas Compressor Station to the east, thereby reducing views from settlements to the west and east.

7 Gas turbine stacks will be sited at eastern edge of site behind the existing line of mature trees to minimise views from the south of the site and from Eye. In the event that less than five stacks are proposed, consideration will be given to the siting of stacks in an alignment so as to minimise views from the west.

8 Consideration will be given to the use of screening within the site to add contour to structures and disguise hard verticals.

9 The height of all structures will be minimised. The design of the project utilises technology (SGCT) to achieve a significant reduction in stack height compared to other technology types. Stacks will be between 25m – 30m height and will not be illuminated or contain signage or branding


unless necessary for a recognized safety/operational requirement.

10 The Cladding scale and colour will be arranged horizontally to ensure the buildings are grounded into the surrounding landscape and at the same time minimise the long distant visual impact. The colour and horizontal profile of cladding will reflect the horizontal strata of the landscape in the foreground and up to a raised platform which incorporates mature tree lines and hedgerows in the far distance and then above that the backdrop of the skyline. The colour and finish of the stacks will be neutral and avoid glare

11 The Gas Turbines will not be sited within a large building, but will be left as individual units to limit the overall ‘mass’ of the Power Generation Plant. This will provide a less dense appearance when viewed from the wider landscape.

12 The main entrance and other permanent accesses will have high quality branded signage so that visitors and passers-by can understand the use of the site

13 Vehicle parking, storage areas and smaller structures will be laid out and screened so as to minimise this low level visual clutter and improve the safety and perception of safety of the site operation.

Electrical Connection Compound Design Principles

14 General

The sub-station will be designed so as to minimise the footprint and sensitively sited taking into account agricultural use, heritage assets, landscape and visual impact and ecology.

15 AIS Variant

The design of the AIS compound will be such that it minimises visual impact by:

siting infrastructure as far as is operationally practicable to silhouette with the landscape;

using non reflective insulators; and


palisade security fencing will be set behind the landscaping.

16 GIS Switchgear and Administration Buildings

In order to reduce the impact of the overall building composition consideration will be given to break up the facades and roof profile into vertical sections similar in scale/width of the neighbouring buildings.


The façade treatment of the administration building should contrast and complement the larger switchgear building. The roofing material should be maintained over both buildings however to give a coherence to the visual impact of the whole.


The façade materials need to ‘seat’ the building into the landscape in a way that existing vernacular buildings do. Consideration should be given to profiled cladding materials arranged vertically.


Consideration will be given to incorporating roof lights or vents that add architectural interest to the large roof scape.


The roof material should not be reflective and the choice of colour and finish should minimise glare.

21 Access Road

The access road will be designed according to National Grid – Civil, Structural and Building Engineering – Design Manual DH10 and will be constructed to allow farm vehicles to traverse over it freely (in a north – south direction) whilst undertaking agricultural operations within adjoining fields. The surfacing treatment will respond to the local context.

General Landscape Design Principles


22 The landscaping mitigation proposals are secured via requirement 4 of the draft DCO, (Document Reference 3.1).

23 Landscaping Design Principles within the Landscape Mitigation Strategy include considerations such as:

the wider opportunities for landscaping around each component of the project to reinforce the character of the surrounding landscape and reduce visual impacts from the Project.

detailed mitigation proposals to screen views from nearby properties and public rights of way.

The design of perimeter security fencing – including colour and alignment

24 Additional landscape mitigation is proposed in the draft s106 Agreement, document 10.4. The s106 includes consideration for opportunities for offsite landscaping to provide both additional landscape and visual amenity enhancement measures.

Power Generation Plant Landscape Principles

25 The Landscape Design Principles within the Landscape Mitigation Strategy include considerations in relation to the Power Generation Plant such as:

Ensuring visual continuity with the National Grid Gas Compressor Station planting scheme through the design of landscaping on the western and southern edges of the Power Generation Plant.

Gas and Electrical Connections Landscape Principle

26 The Landscape Design Principles within the Landscape Mitigation Strategy include considerations in relation to the Gas and Electrical Connections such as:

Reinstatement of land required for construction works for agricultural use and/or landscape mitigation


Planting shallow-rooting species in the permanent easement of the Gas Connection to avoid damage to the pipeline.

Minimising visual intrusion and complementing local landscape character through landscaping around the Electrical Connection Compound.

Selecting species for landscaping to complement the local landscape (subject to approval by National Grid).

Orientating landscaping around the Electrical Connection Compound in order to complement and enhance the historic boundary pattern of the receiving landscape.

Lighting Design Principles

27 A lighting scheme, including layout and lighting principles is provided in the Outline Lighting Layout (document reference 2.10) and secured via requirement 18 of the draft DCO, document reference 3.1. This document does not seek to duplicate or replace those principles.

28 Principle

The Lighting Principles within the Outline Lighting Strategy include considerations such as:

Production of a Lighting Strategy for the design of temporary lighting during the construction phase.

Production of a Lighting Strategy for the design of permanent lighting when the Project is in operation.

Limiting obtrusive light to sensitive receptors surrounding the Project Site which includes residents of nearby settlements, in particular Yaxley and Eye, and key ecological corridors.

Using pole mounted external lighting, generally 6m high, for the Power Generation Plant for internal roads, pedestrian walkways, car parks, security and for buildings to meet operational requirements.


Any development west of the A140 will be unlit, except for maintenance and emergency purposes.

Minimising the impact on key lighting receptors by:

o optimising light levels.

o locating light sources away from sensitive landscape and ecological receptors.

o preventing upward light with shields and baffles.

o minimising the height of light columns.

o the use of infra-red floodlighting and CCTV systems for security at the ECC to reduce the need for visible light outside working hours.

o the use automated devices to switch lights on and off according to activity and ambient levels.

o directing light to the area where it is needed to avoid reflectance from buildings and structures and to avoid illuminating building facades.

The Lighting Strategy will be prepared during the detailed design stage in accordance with guidance provided by the Institute of Lighting Professionals document ‘Guidance Notes for the Reduction of Obtrusive Light’. Glare will be kept to a minimum by ensuring that the main beam of all lights directed towards any potential observer is not more than 70°. (https://www.theilp.org.uk/documents/obstrusive-light/ )

Design Principles

10.2 Design and Access Statement pp 39 - 43

Progress Power Design & Access Statement

39

Eye Airfield Principle

The proposed buildings, structures and perimeter security fencing

shall be of high quality design.

Materials used for cladding shall above all need to be durable and

functional for operation for 25yrs in a power station environment.

The design should be such that it minimises visual impact and

blends with the background and foreground as far as possible,

with recessive colouring.

Consideration should be given to cladding in scale & grades of colour

appropriate to the local surroundings, for the largest buildings, to

minimise visibility in long distance views whilst adding visual interest

at street level. Soft planting along connection routes should be reinstated in

accordance with soil handling and reinstatement strategy to be

developed as part of project CEMP and restored agricultural use.

Where existing trees or soft planting are lost, and cannot be replaced

through tree planting due to restrictions above and adjacent to the

pipeline. Appropriate planting should be reinstated to retain the linear

feature and provide connectivity for wildlife.

Where inside the permanent easement of the Gas Connection, only

shallow-rooting tree/shrub species should be used in order to avoid

interfering with the installed Gas Connection.

Amenity planting should be used to enhance the character of the

industrial estate. The design of perimeter security fencing and its

alignment inside boundary structure planting should provide a ‘soft’

edge to the industrial development, and connect with adjacent trees

and vegetation. Where safe and operationally feasible to do so,

further planting within the interior of the site should be considered

where it provides amenity to both passers by and users of the site

itself.

Design Principle

Specify or design items of larger plant

with consideration to their visual

appearance in the local and wider

landscape.

Reinstate the routes of the gas and

electrical connections with appropriate

planting for their wider and local

landscape and habitat setting, taking into

account the need to avoid damage from

roots.

The use of soft landscaping should be

maxi- mised within the Power Generation

Plant Site where safety and operational

considerations allow.

Analysis Component

Built Form, Uses and Activities



40 Progress Power Design & Access Statement

The approach to screen planting should seek to improve the amenity

of the area and enhance biodiversity, and be carried out in accordance

with the Landscape Strategy. Belts of trees along both western and

southern edges of the site should be planted. The southern edge tree

planting will link with the already mature adjacent plantation along the

eastern boundary of the site. To the north of the site shrub planting

will be planted. All re-instate- ment planting should be native species.

The scheme of lighting should minimise detrimental visual and

environmental impacts. This would be achieved through

appropriate placing, directionality, and technology of lighting and a

preference for a greater number of lower level, building mounted

lamps. Design choices for lighting should be made with a view to

minimising the impact. Any development west of the A140 should

be unlit, except for security and emergency purposes.

The height of all plant should be minimised. The design of the project

utilises technology (SGCT) that allows a significant reduction in stack

height compared to other technology types. Stack shall be between

25m – 30m height and shall not be illuminated or contain signage or

branding unless necessary for a recognised safety / operational

requirement.

A landscaping scheme should be

developed that ensures the site is

designed and landscaped to

complement the local and wider setting,

and screen in identified views.

Good quality trees shall be retained.

Lighting shall be appropriate to the local

context, to create visual interest at the

street level if appropriate but avoid

lighting impacts upon identified

habitats, neighbouring occupiers, and

the wider landscape.

Stacks should be designed at a height

which causes minimum visual impact

whilst also allowing for adequate

dispersion of stack emissions

The main entrance and other permanent accesses shall have high

quality branded signage so that visitors and passers-by can

understand the use of the site.

Vehicle parking, storage areas and smaller structures shall be laid

out and screened so as to minimise visual clutter and improve the

safety and perception of safety of the site operation.

The visual impact of low level clutter should be effectively

minimised through design, layout, bunding and planting.

The CEMP shall include measures for the maintenance of a tidy

and contained site compound during construction

Detailed design shall ensure that noise is mitigated as far as possible,

through the Project Site layout and consideration of the orientation of

plant items associated with higher sound power levels. Inherently

quiet plant items shall be selected wherever practicable.

Consideration shall be given to the use of silencers and housing

plant items in acoustic enclosures where practicable.

Materials chosen shall be robust, high quality and cost-effective. The

architectural design, use of raw materials and colours of the buildings

and structures on the Eye Airfield Site shall be designed to reduce

glare and assimilate the Project into the surrounding landscape.

Re-use existing entrances to provide adequate operational and

safety access.

Design of new access track for the AGI shall minimise hard standing

area and grassland loss whilst remaining clear for the necessary

vehicles to access.

Where removed for construction works, roadway and footpath

shall be reinstated with a durable and well-finished surface

Vehicle parking shall be adequate for workers and visitors to the site

and shall include a fully accessible space for a disabled worker or

visitor, and be proximate to buildings they serve.

The Power Generation Plant Site shall be

laid out and maintained in a safe and

attractive manner and which supports a

positive public perception of the

operation.

The site layout shall consider the need to

minimise noise and vibration impacts on

the wider area.

Consideration shall be given to the

most appropriate choice of materials.

Materials should be agreed with the

local planning authority.

Ensure that access routes are appropriate

for the vehicles that shall use them during

site construction and operation

The design should be accessible to

existing public transport routes and

mitigate any significant transport impacts

Landscaping proposals should be

appropriate to the context of the

individual elements of the scheme.

Landscaping around the Electrical Connection Compound should

minimise the visual intrusion and complement local landscape

character; particularly in relation to species choice. Orientation of the

planting must complement and enhance the historic boundary pattern

of the receiving landscape.

Landscaping around the Power Generation Plant should be

designed to ensure visual continuity with the planting scheme used

to conceal the National Grid Gas Compressor Station.

Wider opportunities to reinforce the character of the landscape and

reduce visual impacts within the Project Site boundary should be

explored.

Opportunities for offsite landscaping will be investigated to provide

both additional landscape and visual amenity enhancement

measures. Landscape/

Environmental suitability

Retain and reinforce boundary tree planting

where trees are found to be of

good/retain- able quality.

The design shall take into account the

provision of robust fencing around the site

to ensure safety of the site.

The design of perimeter security fencing and its alignment inside boundary

structure planting shall provide a ‘soft’ edge to the industrial

development, and connect with adjacent trees and vegetation.

Amenity planting shall be used to enhance the character of the

industrial estate.

Natural surveillance shall be facilitated through the location of the gate-

house and the use of chain link or weld mesh fence where safe to do

so, in preference to solid hedge or wall.

Trees should be maintained/selected to have a canopy no lower

than around 1.8m to allow some short / angled views in and out of

the site whilst acting as screening to taller and more distant

structures within the site.

The design of landscape planting should enhance the area’s

biodiversity through: the retention of existing trees & bushes; the

planting of belts of broadleaved woodland to increase the amount of

natural green landscape in the area; the reinstatement of planting

where possible and appropriate; and careful management of soils.

The routeing and installation of the utility connections should

minimise the impact on existing landscape and ecological features

and the sterilisation of land – careful routing and/or Horizontal Direct

Drilling (HDD) or similar methods should be used where possible.

The design of the site shall include the strategic placement of soil

bunds and design considerations for access roads in order to avoid

funnelling surface water or affecting surface water quality off site.

Sustainable drainage systems will be used to manage surface water

runoff and if possible create new habitat for wildlife. Water use should

be minimised. Irrigation systems, making use of captured rainfall,

may be included within the landscaping to ensure that it is effective.

Landscaping proposals should be sympathetic to the historic

character of the landscape, in their alignment, scale and

composition.

The impact on the setting of listed buildings and conservation areas

should be fully evaluated and mitigated for.

Minimise impacts on existing habitats

and species within the site.

The layout and landscaping shall be

designed to minimise all aspects of

water usage where operationally

appropriate, thus process, sanitation and

irrigation water usage.
