About usWe’re one of the world’s largest power and gas companies.

Here in the UK, we supply energy to more than 5 million

customers, generate enough electricity for around 8 million

homes and employ 12,000 people.

We set up a global business in 2007 to develop, construct and

operate all of our renewable energy projects. We’re helping

to shape the energy industry of tomorrow and create secure,

sustainable energy supplies for future generations.

In the UK, we’re focusing on developing onshore and offshore

wind, biomass and marine energy technologies. At present, we

own and operate 18 onshore wind farms and 3 offshore wind

farms. Together, these have an installed capacity of more than

400 megawatts (MW).

Our offshore experienceWe were early pioneers in the UK’s offshore wind energy industry,

owning and operating the UK’s very first offshore wind farm at

Blyth in Northumberland.

We built and operate one of the country’s first commercial scale

projects, Scroby Sands in Great Yarmouth, which has 30 turbines

with an installed capacity of 60MW. Our third operational offshore

wind farm, the 180MW Robin Rigg project, was completed in 2010

and has 60 turbines. In February 2011, we received planning consent

to build the 219MW Humber Gateway Offshore Wind Farm off the

east coast of Yorkshire, which will be starting construction shortly.

Building the world’s largest offshore wind farmIn March 2011, we started laying the first of 177 foundations on

Phase One of London Array, an offshore wind farm project that

we’re undertaking with our partners DONG Energy and Masdar.

When fully complete, London Array will be the largest offshore

wind farm in the world.

The UK’s energy gapFillingtheenergygap

Over the next 10 years, many of the older coal-fired and nuclear power stations

in the UK will close, resulting in a potential ‘energy gap’. We need to act now

to replace these power stations with cleaner, more effective solutions such

as renewable energy technologies. However, no single energy source holds the

answer on its own. That’s why we’re developing a range of generation methods,

with renewable energy sources such as wind, biomass, wave and tidal power.

Whyweneedoffshorewind

With its long coastlines and as one of Europe’s greatest wind resources, the

UK is uniquely placed to harvest offshore wind energy and lead the world in

offshore wind development.

Offshore wind is currently the only renewable energy technology which can

be built on a scale comparable to many conventional power stations, to achieve

the Government’s targets for producing renewable energy and reducing carbon

dioxide (CO2) emissions. It offers the additional benefits of higher than average

wind speeds and reduced turbulence, all leading to a greater energy yield.

Cleanerandbetterenergy

To help build a secure energy future, we need to change the way we think about

energy, from how we generate it, to how we use it in our homes and businesses.

As one of the UK’s leading electricity and gas companies we’re working hard to

make our operations cleaner and better. At the same time, we’re helping our

customers get ‘energy fit’ by giving them the tools they need to start saving

energy and money.



Background and historyThe Rampion site was identified following the Government’s

Offshore Energy Strategic Environmental Assessment (SEA),

which looked at the potential for new large-scale offshore

wind farms in UK waters. The SEA looked at a whole range

of environmental and technical criteria to establish the

area as suitable for wind farm development, including:

•wind speed

•water depth

•distance from shore

•major shipping lanes

•environmental designations

•other uses of seabed, eg aggregates extraction.

Nine zones were identified and The Crown Estate, which owns

the seabed around the UK, launched a tender process known

as ‘Round 3’, to award development rights. In January 2010, we

were awarded exclusive development rights in an area off the

Sussex coast, to seek to build and operate an offshore wind farm.

This was initially called Zone 6. A single offshore wind farm project

has now been defined within the zone. The Rampion site and its

associated offshore and onshore infrastructure form the basis

of this consultation.

WhyRampion?

The project has been named

the Rampion Offshore Wind Farm

after the county flower of Sussex.

We held a competition among local

schools to choose a name for the

site. Pupils from Davison High

School in Worthing put forward

the shortlisted entry and the final

name was decided by a public vote.



What we’re proposingThe project has offshore and onshore elements:

Offshore

•turbines and foundations

•inter array cables

•two offshore substations

•offshore export cables.

Onshore

•cable ‘landfall’

•underground onshore cable route

•onshore substation.




Figure1–ProposeddevelopmentareaoftheRampionOffshoreWindFarm

The solid red line boundary defines the site location for the offshore wind turbines. However,

a potential additional development area (marked by a dashed red line) coincides with an area

over which The Crown Estate has granted an aggregates extraction option (shown as a yellow

hatched area), which is valid until 2013. For the purposes of this community consultation, and

in order that all issues can be addressed, consultees should therefore assume that a consent

application for turbines within the area bounded by the dashed red line, may be sought.

Rampion project statisticsLocation – 13km to 23km off the Sussex coast

Site area – 167km2

Water depth – 19m to 50m

Installed electrical capacity – up to 700 megawatts (MW)

Turbine size – Turbines will have a generating capacity of between 3MW

and 7MW, with respective maximum height to tip of 180m and 210m.

Turbine numbers – Up to a maximum of 195 x 3MW or 3.6MW units.

For larger turbines, the number of units needed to generate 700MW

would vary.

Onshore works – A 27.8km underground cable route from the landfall

to the 400 kilovolts (kV) substation (owned by National Grid), around

2km south-west of Bolney village.

Power output – Based on our current expectations of the area’s wind

resource over the long-term, we estimate the site could generate more

than 2,100 gigawatt hours (GWh) of electricity each year*. In a typical

year, we estimate the project could generate enough electricity for the

domestic needs of the equivalent of around 450,000 homes#. That’s more

than two thirds of the homes in the whole of Sussex†, including the city

of Brighton and Hove.

* Based on wind speed data from our existing offshore wind farms in UK waters. This will be updated as Rampion site-specific data is gathered.

# Based on an average annual domestic household electricity consumption of 4,700kWh (DECC).

† Office of National Statistics census data.




1.Providingclean,renewableelectricityonalargescale

In a typical year, we estimate the Rampion Offshore Wind Farm

could generate enough electricity for the domestic needs of

the equivalent of around 450,000 homes# each year. This could

contribute to reducing the UK’s reliance on imported fuels,

help increase our security of supply and stabilise electricity

prices in the future.

2.ReducingCO2emissionsintheUK

We believe the Rampion project could avoid the emission of

over 920,000 tonnes† of CO2 each year, which would otherwise

have been released by conventional power stations.

3.Enhancingmarineecology

Environmental monitoring at operational wind farms has shown

that positive habitat changes in marine ecology can occur in and

around turbine foundations acting as a natural reef. We’re currently

monitoring the ecology at our Robin Rigg Offshore Wind Farm in

the Solway Firth, and a wide range of fish species are now being

found in the wind farm area.

# Based on an average annual domestic household electricity consumption of 4,700kWh (DECC).

† Every unit (kWh) of electricity produced by the wind displaces a unit of electricity, which would otherwise have been produced by a power station burning fossil fuel. This is a generally accepted fact used by many organisations including Government in their environmental calculations. Wind-generated electricity does not replace electricity from nuclear power stations because these operate at ‘base load’, that is they will be working for the whole time that they are available. The calculation is made using a static figure of 430g CO2/kWh representing the energy mix in the UK.



4.Boostingthelocaleconomy

The Rampion project will offer a boost to the local economy in a

number of ways. We will:

•create between 65 and 85 full-time, permanent jobs, mostly in the local area

•establish a permanent Operations and Maintenance (O&M) base at a local

port (we’re currently in discussions with Newhaven and Shoreham ports)

•use local companies to provide services, such as vessels, construction

activities and engineering consultancy

•create indirect benefits from our construction and operational activities,

such as increased revenue to hotels and local businesses

•raise awareness of the opportunities and timescales on which local

companies could tender for contracts on the project.

We’ll try to use local labour and services as much as possible during all phases

of the project. We currently employ a full-time member of staff in Brighton, and

use a number of local companies to provide vessels, consultancy services and

undertake ecological surveys to support the wind farm’s development.

5.Supportingtourism

Offshore wind farms may enhance tourism potential by providing a feature

of interest. Our Scroby Sands Offshore Wind Farm, off the coast of Great

Yarmouth in Norfolk, has operated a visitor centre on the promenade since

2004. In 2010, it attracted 40,000 visitors from both the local community and

holidaymakers visiting the area. Additionally, some local operators run boat

trips out to the wind farm.

Scroby Sands Offshore Wind Farm Visitor Centre, Great Yarmouth.



Wind turbinesWe’re looking at three-bladed horizontal axis turbines, with a generation capacity

of between 3MW and 7MW. This is subject to the maximum installed capacity

of 700MW and a maximum of 195 turbines. For example, if we select a 3MW or

3.6MW turbine, then we’ll install 195 units. If we choose a larger 7MW turbine,

then a maximum of 100 turbines will be installed. Figure 2 shows the relative

dimensions of three wind turbines within the 3MW to 7MW range. Please note,

intermediate turbine sizes within this range are also available, so the number

of units needed to generate 700MW may vary.

When we apply for the Development Consent Order (DCO), we’ll be looking for

flexibility in the number and size of the wind turbines, so that within certain

limits several different final configurations will be possible.

Indicative layoutsThe turbines will generally be set out in a regular grid pattern, at least 600m apart.

We’ll decide on the exact location of the turbines and offshore substations when

the environmental and engineering constraints are known, and we’ve undertaken

further site investigation work. The turbines will be marked for navigation purposes

and painted in a light grey finish, the industry standard for offshore wind turbines.

Figures 3 and 4 show two indicative layouts for the offshore site. Figure 3 shows

the layout with the greatest number of turbines and Figure 4 shows the layout

with the largest turbines proposed.

FoundationsThe turbines will have a tubular steel tower placed on foundations which will sit on or in

the seabed. We’re currently considering a number of foundation types, including what are

known as monopile, gravity base, jacket, tripod and suction caisson. A number of factors

will dictate the appropriate technical solution, including the type and size of the wind

turbine, water depth, seabed ground conditions and metocean conditions. These elements

will be further considered during the Environmental Impact Assessment (EIA) process.

Inter array cablesWe’ll need to install a network of inter array cables, likely to be rated at either

33 kilovolts (kV) or 66kV, to transfer electricity from the wind turbines to the offshore

substations. These cables will be buried under the seabed either by ploughing, jetting

or trenching to a target burial depth of 1m, subject to local conditions. We’ll decide on

the exact location of the array cables once the turbine locations are known. The inter

array cable layout will be designed to limit the amount of cable installed.

Offshore substationsTwo offshore substations will be installed within the grey hatched area shown in Figures

3 and 4. The purpose of these substations is to collect the electricity generated by the

wind turbines via the inter array cables and step up the voltage, before transmitting it

to shore via the export cables. The offshore substations will be steel-framed structures

housing electrical equipment. The total height of the substation is likely to be up to 45m

above Lowest Astronomical Tide (LAT). The substations are expected to be marked for

navigational purposes in a similar way to the wind turbines.

Export cablesWe’ll need to lay four individual export cables to transfer the electricity to shore,

two from each offshore substation. Like the inter array cables, the export cables will

be buried under the seabed either by ploughing, jetting or trenching to a target burial

depth of 1m, subject to local conditions. The voltage of the export cables is expected

to be between 132kV and 150kV.

Offshore substation at Robin Rigg Offshore Wind Farm, Solway Firth. For illustrative purposes only.


Construction of the offshore elementsDue to the scale of the project, it’s likely that offshore construction would be spread

over a period of two to three years from the initial works to full commercial operation.

A large jack-up barge would typically be used to install the foundations of the turbines

and offshore substations, whilst another barge would transport turbine components

to be lifted by crane and installed on to the foundations. We’re likely to carry out both

these activities, along with the offshore cabling works, at the same time. Figure 5

shows an installation sequence used at Scroby Sands Offshore Wind Farm based

on monopile foundations.

Decommissioning the wind farmIf the project is approved, a seabed lease would be granted for 50 years. The design

life of current wind turbine technology is typically 20-25 years, so at the end of this

period a decision would need to be made whether to refurbish the scheme, replace it

with newer turbine technology, or decommission the project. Any new turbines would

require a fresh consent application and supporting Environmental Impact Assessment.

To mitigate visual impact from the coast

Avoid conflicts with major shipping channel (actual separation in this proposal is 2.8nm)

This is what we consider to be the technical water depth limit for constructing offshore wind farms at this time

To aid marine navigation around or through the site, particularly in adverse weather or emergency situations

To minimise restriction to navigation through the site and to avoid a visually dense development

Avoid direct impacts on shipwrecks or other features of interest

Maritime guidance to ensure adequate clearance from vessels

Avoid conflict between different uses of the seabed (Note: ongoing discussion with one operator)

Avoid risk of cables being snagged by anchors or nets



Onshore substationWhyBolney?

The electricity generated from the Rampion project will be similar in scale

to that produced by a conventional power station. It therefore needs to be

connected into the National Grid’s UK electricity transmission system at a

voltage of 400kV. We initially looked at opportunities to connect into the

132kV distribution system nearer to the coast, but our studies confirmed

this would not be possible.

We had initial discussions with National Grid and through careful

evaluation of environmental, technical and commercial criteria, we selected

Bolney Substation as the most suitable connection point. The substation

lies around 2km south-west of the village of Bolney in Mid Sussex and sits

within fields which are very well screened by trees. The topography also

helps limit views of the substation from Wineham Lane, Bob Lane and

Twineham Lane.

The existing National Grid Bolney Substation in Mid Sussex. For illustrative purposes only.



Substationdevelopment

The search area we’re considering is shown by the red line boundary

in Figure 6. The exact location of the substation depends on ongoing

landowner negotiation, engineering and environmental work.

We anticipate that the overall land area required by the new substation

will be around half the footprint area of the existing Bolney Substation

and is not expected to contain any equipment taller than 10m.

Figure6–Gridsubstationsearcharea

The substation would contain a range of electrical equipment, including

transformers, reactive compensation equipment, control buildings (likely to be

two storeys high) and amenities buildings, all surrounded by security fencing.

It’s anticipated that the substation will take two years to build.

The likely dimensions for key equipment within the substation area are:

•transformers – 6m wide x 16m long x 10m high

•reactors – 4m wide x 7.5m long x 7m high

•filters – 20m wide x 22.5m long x 8m high.


700MM x 1000MM FOAMEX BOARD – ARTWORK SET TO 100%

Onshore cable routeFigure 7 shows the proposed cable route, which is 27.8km long. We would lay the

cable underground for the whole route, to avoid the long-term visual impacts from

an overhead connection.

Section 1

At the preferred landfall location, the proposed cable would be drilled under the beach,

the sea defences and underneath the A259 between East Worthing and Lancing, before

continuing under parts of the Brooklands Pleasure Park, Pitch and Putt, and Par 3 Golf

Course. The route passes close to the Southern Water works before crossing into open

space. It generally runs alongside the route of the new cycle path, until it passes under

an overgrown former landfill site.

Sections 2, 3 and 4

From here, the cable would be drilled under the railway and head north through open

land towards the A27 Sompting Bypass where another drilled section will be installed

under this major road. At this point, the cable route enters the South Downs National

Park and then heads generally north-east, avoiding the Site of Special Scientific Interest

(SSSI) at Steep Down. It then heads directly east to cross the River Adur, south of the

disused cement works.

Section 5

The route gradually ascends towards Beeding Hill. Beyond this point is the most

constrained part of the route, particularly at Tottington Mount where the route crosses

the hilltop, before taking a U-shaped course to maintain workable slope inclines. There

is a Scheduled Ancient Monument (SAM) here, a Bronze Age Cross Dyke, which the cable

can’t avoid due to slopes on either side. We held a meeting on site with English Heritage

to discuss a suitable methodology to limit the impact and agree further investigations to

understand more about this feature. The route then descends from the South Downs into

the open plain to the north and towards the Low Weald.

Sections 6 and 7

The route passes through generally open farmland, avoiding a Site of Nature Conservation

Importance (SNCI) and ancient woodland near Small Dole. The proposed route crosses

the A281 at a point between Henfield to the west and Woodmancote to the east. It then

heads north, passing to the west of Blackstone before reaching the B2116.

Section 8

The cable route then heads directly north, keeping around the same distance from

Wineham in the west and Twineham to the east, before crossing under Bob Lane and

then reaching land next to Bolney Substation. At that point, it will connect into a new

dedicated Rampion substation for connection to the National Grid.


Figure 7 – Map of proposed underground onshore cable route

We also have larger scale maps of the eight individual sections of the onshore

cable route available. Please ask a member of the project team to see a copy.

The Parish (or Borough/District) Council areas that the proposed cable route passes through are Worthing Borough, Sompting, Coombes,

Adur District, Upper Beeding, Henfield, Woodmancote and Twineham.

Cable landfall With the grid connection point defined as Bolney Substation, we then started a

process to identify the preferred route for underground cabling from the wind farm

to reach this location. It was important to carefully select the landfall location, where

the marine cables would be brought ashore.

The degree of urbanisation along the Sussex coastline meant that potential landfall

locations were extremely limited. Cliffs and environmental designations ruled out a

route to the east of Brighton, and taking a route west of Worthing would have resulted

in unnecessarily long offshore and onshore cable routes with associated environmental

impacts. So we defined a search area in between Worthing and Shoreham, and three

possible cable landfalls were identified within this area:

•between East Worthing and Lancing, through Brooklands Pleasure Park

•eastern end of Widewater Lagoon in Shoreham-by-Sea and through the beach

•west of Norfolk Bridge, Shoreham-by-Sea.

Following a number of studies, we decided that the most suitable option would be

between East Worthing and Lancing, through Brooklands Pleasure Park. The Widewater

Lagoon option would have required demolition of at least two existing houses, so was

immediately discounted. The cable landfall near Norfolk Bridge would have impacted

on a Local Nature Reserve and the cable would also have been routed through a Site

of Special Scientific Interest (SSSI). Furthermore, this option would have impacted on

residents of house boats on the River Adur, owners of beach huts, and required closure

of a children’s outdoor play area.

What’s an EIA?We’re carrying out an EIA for the project, which means we look at the current

environmental conditions and identify any impacts that may arise as a result

of the project. We’ll then look at ways in which we can reduce these impacts

through mitigation – either through design or other measures. This is being

undertaken in line with UK and European EIA legislation.

EIA–currentstatus

We’ve carried out surveys to help us establish the baseline conditions for

the offshore site and onshore elements of our proposal. We’ve also looked

at each of the project’s lifecycle phases in turn, to identify the impacts

which could arise from:

•the wind farm’s initial construction phase

•the operational phase

•the eventual decommissioning of the wind farm at the end of its

operational lifetime (typically 20 to 25 years).

The following tables show the offshore and onshore surveys we’ve

undertaken so far.

Ornithologists have been identifying the bird species, their activities and the numbers present in the area of the offshore wind farm and across a wider reference area. These surveys have been carried out by boat and by plane on a monthly basis (twice a month in spring and autumn) since March 2010, as we need to collect two years of site-specific bird data.

Alongside the ornithologists, marine mammal experts have been recording the numbers of seals, dolphins, porpoises and whales in the area of the offshore wind farm and a wider survey area.

To understand the flora and fauna that live on the seabed, we’ve sampled a number of sites along the cable route and in the wind farm area to identify any species of conservation interest within the area, and their relationship to the wider ecological network.

We’re looking at the fish ecology so we can understand the fish species that occur in the area and their breeding or nesting sites.

We’ve been engaging with commercial fishing organisations and fishermen who use the area for commercial fishing activities. We’ve also set up a project liaison group to meet regularly so we can collect information on the types of fishing activity which occur in and around the offshore wind farm site.

We’ve undertaken non-invasive geophysical surveys across the entire offshore site to obtain bathymetry information (the shape of the seabed), and to provide details of the site’s seabed geology. We then carried out geotechnical surveys which involved drilling a number of borehole samples at key points on the site, to further understand the conditions under the seabed.

We’ve been monitoring the movement of vessels in and around the proposed wind farm site to understand how ships and other vessels use the area. This includes the movement of commercial vessels in and out of ports, and how recreational users use the area.



EIA–currentstatus(continued)

Although we’re still carrying out the EIA for each element of the project, we’ve already

identified potential impacts to the local community that could arise as a result of developing

the Rampion Offshore Wind Farm. We’ve presented these for both the offshore and onshore

elements, and in terms of temporary impacts (construction phase) and ongoing impacts

(operational phase).

Engineeringsurveys

We’ve mapped the presence of bats, birds, dormice, badgers, newts and plants, amongst other flora and fauna along the cable route. We’ve also taken account of trees, hedgerows and agricultural practices along the route. Surveys were carried out at appropriate times of the year by suitably experienced and, where necessary, licensed ecologists.

We’re undertaking geophysical surveys along the route to establish whether there’s any evidence of cultural and historical interest in close proximity, such as archaeological artefacts and historical roads, fields or settlements.

These surveys will enable us to refine detailed engineering methodologies, better quantify likely environmental impacts and identify potential mitigations to these impacts.

What are photomontages?Photomontages are photographic illustration tools which give an indication

of the potential scale and extent of the proposed development. They’re used

to gain an appreciation of how the proposed development may appear within

any given view and are intended for guidance only.

How should I view the images to give the best representation?The relative viewing distance needs to be correctly understood, eg if an image

is viewed too far from the eye then the elements will appear too small, whilst

if an image is viewed too closely, elements will appear disproportionately large.

The photomontages displayed today are printed to a width of 150cm and present

a 120° field of view. To view these images at the scale that best represents what

you would see in real life, you’re advised to view them at a distance of 72cm.

Which turbine layouts have you used to generate the images?For the purpose of this community consultation, we’ve produced photomontages

based on 195 x 3.6MW turbines (‘worst case scenario’) for each of the viewpoints,

and an additional indicative photomontage for 100 x 7MW turbines from Brighton

Seafront Promenade (Viewpoint 02), for comparison purposes.

Our Environmental Impact Assessment (EIA) work to date indicates that a greater

number of the smaller turbines (195 x 3.6MW) would have a more significant impact

on the seascape than fewer larger turbines (100 x 7MW), as they look more densely

packed on the horizon and the height difference in the turbines is difficult for the

eye to make out from a distance of 13km.




Consenting processThe Rampion Offshore Wind Farm proposal is defined as a Nationally Significant

Infrastructure Project (NSIP) under the Planning Act 2008. This is because it will

have an electrical output greater than 100MW.

Unlike planning applications which are submitted to local authorities under the

Town and Country Planning Act, we’ll be applying to the Infrastructure Planning

Commission (IPC) for a Development Consent Order (DCO) under the Planning

Act 2008. The IPC currently decides applications for NSIPs within the framework

of the relevant National Policy Statements, although the regime for authorising

NSIPs is to be amended by the recently enacted Localism Act 2011. Under the

revised provisions, the IPC (or its successor) will examine the application and

recommend to the Secretary of State if it should be approved.

Once the application is lodged with the IPC, all interested parties will have a

further opportunity to comment on the proposals by contacting the IPC directly.

ConsultationThere is a legal requirement for developers of Nationally Significant Infrastructure

Projects, such as the Rampion Offshore Wind Farm, to consult with the community

under Section 47 of the Planning Act 2008. A Consultation Report detailing consultation

responses will accompany our application for a DCO to the IPC in 2012.

Although we’re legally required to consult with the community, we also understand

that our relationship with the community is vital in developing a successful project.

As with all our other projects around the UK, we’re keen to build strong relationships

with the community and be good neighbours throughout the lifetime of the project.

The aims of our community consultation are to:

•provide an opportunity for the local community to review our proposals, understand

the project and what it will mean to them

•enable the community to put forward any views and ideas they have which may

influence certain elements of our proposals

•help the community understand any impacts our proposals may have on them, and

help shape any potential mitigation measures we could use to lessen these impacts

•encourage communities to actively participate and engage with us.

The community consultation will run for a period of 12 weeks from

Monday 13 February 2012 until Sunday 6 May 2012.
