1 Introduction

1.1 Overview

1.1.1 This report details the pre-application community consultation process undertaken for the proposed Melgarve Substation (the Development). The Development is required to connect the Stronelairg wind farm to the transmission network. As such, the consultation process has taken a holistic approach and includes reference to the grid connection as a whole.

1.1.2 Consent for construction of the new 400 / 132 kV substation is being sought by way of a planning application to The Highland Council under the Town and Country Planning (Scotland) Act 1997. Due to the size of the substation being in excess of 2 hectares, the development falls within the category of ‘Major Development’ under the Town and Country Planning (Hierarchy of Development) (Scotland) Regulations 2009 (The Hierarchy Regulations). Community consultation has occurred in line with the procedures set out within these regulations.

1.1.3 This report sets out the means by which the community consultation was undertaken, the responses from such consultation, and how these have been addressed in producing the final design of the Development.

2 Community Consultation

2.1 Community Council

2.1.1 Throughout the development process, regular updates have been provided to Badenoch and Strathspey Community Council.

2.2 Public Exhibitions

Site Selection and Route Options Stage 2.2.1 During the site selection, route options and preliminary design stage of the project, a

public exhibition was held at Laggan Village Hall, Newtonmore on 9th October 2014 from 14:30 – 19:30.

2.2.2 Adverts were placed in The Badenoch and Strathspey Herald on 18th September 2014 and 2nd October 2014. A copy of the advert is included in Appendix 1.

2.2.3 Elected Councillors from The Highland Council were contacted in advance of the newspaper adverts (5/9/14) being made public to formally bring their attention to the project. Members of the project team subsequently attended the Badenoch and Strathspey Ward meeting to provide details on the project and the planned consultation. The meeting was held at Grantown-on-Spey townhouse on 9th October 2014.

2.2.4 The Laggan Community Association were contacted (5/9/14) at the same time as the elected Councillors to announce the project. A meeting was held on 30th September 2014 with the chair of the community association to provide details on the project and planned consultation event.


May 2015 Page 3

2.2.5 Posters were placed on the Laggan Village notice board and handed into the local shop and Laggan Forest Trust offices.

2.2.6 The event was also advertised on the www.ssepd.co.uk/melgarve webpage (subsequently changed to www.ssepd.co.uk/stronelairgwindfarmconnection) and was advertised via social media (SSEPD facebook and twitter channels).

2.2.7 A series of A1 exhibition boards were on display at the events to explain the proposals and a leaflet was available providing contact details for attendees. A comments form was also available at the exhibition and on the SSE website. A copy of the leaflet is included in Appendix 2 and a copy of the boards is included in Appendix 3.

2.2.8 A total of 25 members of the public attended the Laggan Village Hall exhibition. Attendees included residents, members of the community council, landowners and local business people.

2.2.9 A total of 44 people provided responses. The main comments received from the public

were as follows:

22 specific objections to the grid connection project;

13 specific objections to Stronelairg wind farm;

1 preference for site A near Melgarve;

9 preferences for site B near Garva Bridge;

6 preferences for a GIS substation;

1 preference for an AIS substation;

10 preferences for an underground cable connection;

0 preferences for an overhead connection; and

9 preferences to re-routeing the connection ‘via Glendoe and Fort Augustus.’ Consideration of Public Responses during Design Evolution

2.2.10 Opinions expressed during the public consultation exercise helped reinforce the potential constraints and sensitivities of proceeding with an overhead line connection between the Development and Stronelairg wind farm onsite substation.

2.2.11 Views on substation site selection were taken on board during more detailed analysis of potential substation sites, where practicable or technically feasible.

2.2.12 Following consideration of consultation responses, a decision was made to progress with

an underground cable connection to the wind farm. A detailed substation site selection was undertaken, and a preferred site within the vicinity of Site B identified. A GIS solution was preferred, primarily due to its reduced footprint. Pre-Application Stage

2.2.13 In order to inform the local community of these project decisions, and to take on board any comments in relation to the final design, an additional community consultation event was held at Laggan Village Hall, Newtonmore on 12th February 2015 from 14:00 – 19:00.

2.2.14 Details of the event were advertised in The Badenoch and Strathspey Herald on 29th January and 5th February 2015. A copy of the advert is included in Appendix 4. The event

http://www.ssepd.co.uk/

Page 4 May 2015

was advertised locally, on the www.ssepd.co.uk/stronelairgwindfarmconnection webpage and via social media (SSEPD facebook and twitter channels).

2.2.15 A series of A1 exhibition boards were on display at the event to explain the proposals and to provide contact details and comments form for attendees. A leaflet for attendees to take away for information, including contact details for comments was also available (see Appendix 5). Copies of the exhibition boards (at A4 size), are included in Appendix 6.

2.2.16 A total of 46 members of the public attended the exhibition in February. A large number of

attendees attended at 6pm as an organised group which provided an opportunity for SHE Transmission to address any comments or concerns expressed by the local community in a co-ordinated manner.

2.2.17 Attendees included Cllr Gregor Rimell, Chair of the Laggan Community Association, and

John Low from the John Muir Trust.

2.2.18 Key issued raised by the community, and how these measures were addressed, are included below:

The wind farm development: Many of those who attended raised issues about the wind farm development itself. Members of the public were asked to contact the wind farm developer with these concerns.

Landscape Mitigation Screening: Many attendees were keen to see the site screened from Wades Road. Attendees were informed that landscape mitigation measures, in the form of planting predominantly to the south and east of the substation will be implemented to ensure the Development is screened from Wades Road as far as practicable.

Additional Connections: Many attendees were worried that the substation would enable other developers to proceed with plans to build new wind farms. Members of the project team explained SHE Transmission are legally obliged to provide connections to developers and at the time of asking no additional connection requests had been received.

Continuing construction activities following Beauly to Denny: Residents of Strathmashie cottages raised concerns regarding construction vehicles passing their homes again following the construction of Beauly to Denny. SHE Transmission confirmed that this access route followed a decision from The Highland Council road’s department during the consenting of Beauly to Denny overhead line to restrict access to Spey Dam via Laggan itself. A review was undertaken by the Project team to assess whether there was any way of moving construction traffic away from the cottages. Unfortunately the existing access track is the only feasible way of gaining access to the glen.

Developers and the Planning System: Concerns were raised by members of the public with regard to the lack of requirement for wind farm applications to include consideration of grid connection options within their planning / section 36 applications. SHE Transmission advised that this is a planning policy matter and is outwith its control.

Who pays for the project?: Members of the project team explained that SHE Transmission is regulated and that the wind farm developer would underwrite the cost of the connection through their contract with National Grid.

http://www.ssepd.co.uk/stronelairgwindfarmconnection


May 2015 Page 5

Why Garva Bridge?: Attendees were provided with an explanation of the rationale behind selection of the site and the overall connection option.

Compensation / Community Funds: Members of the public queried the position with regard to compensation and community funds. SHE Transmission team members explained that as a Regulated business it is unable to provide such funding.

Noise: Several residents were concerned about operational noise. Members of the SHE Transmission team explained that pre-construction measurements would be taken, a noise impact assessment undertaken and appropriate mitigation installed if required.

3 Future Opportunities for Engagement

3.1.1 During the construction phase, every effort would be made to cause least disturbance to landowners and local residents by providing regular updates on works via the on-site Project Manager and Community Liaison Officer. A Community Liaison Group may be established which would provide regular updates from the Project Team.

APPENDIX 2: EXHIBITION LEAFLET (OCTOBER 2014)

Stronelairg Wind Farm 132 kV Grid Connection

About SSE Power Distribution

Project Description

As we are the only company that owns an electricity

transmission network in the north of Scotland we are

closely regulated by the energy regulator Ofgem. We are

issued with a licence to operate and we must adhere to

the terms of the licence. For this reason we are operated

on a very separate basis to other SSE businesses.

Our licence stipulates that we must develop and maintain

an efficient, coordinated and economical system of

electricity transmission.

Our responsibilities also extend to ensuring that there is

sufficient network capacity and a connection for

developers who wish to export their generated electricity

to the national grid. If a generator applies to connect to

our network, we are required to facilitate this under the

terms of our licence.

Scottish and Southern Energy Power Distribution is

part of the SSE plc group of companies. We own,

maintain and invest in the electricity networks in the north

of Scotland – the electricity transmission network (132

kV and above) and the electricity distribution network

(below 132 kV). In Scotland, Scottish and Southern

Energy Power Distribution is made up of two

businesses:

Ÿ Scottish Hydro Electric Transmission (SHE

Transmission) owns and maintains the electricity

transmission network across the north of Scotland,

in some of the UK’s most challenging terrain; andŸ Scottish Hydro Electric Power Distribution

(SHEPD) operates the high and low voltage electric-

ity network that distributes electricity to around

700,000 customers in north mainland Scotland and

the Scottish islands.

A request has been made to National Grid by the

developer of Stronelairg wind farm to provide a grid

connection to connect the wind farm. As the wind farm is

in our licence area, we are responsible for providing the

infrastructure needed to connect the wind farm.

The proposed grid connection would comprise a new

connection from the Stronelairg wind farm on-site

substation, to a new 132 / 400 kV substation located

adjacent, or within close proximity to, the existing

transmission network. A new overhead line OR

underground cable would be required to complete the

connection between the substations.

We are undertaking a route options appraisal and

substation site selection exercise to identify a

technically efficient and economic route and location

for the grid connection, taking into account

environmental factors to minimise any potential

adverse impacts on the environment.

We are currently at an early stage of the project and are

seeking views from local residents about our

proposals.

Stronelairg Wind Farm: Location

We need to identify a suitable site to accommodate a

new substation. In order to do this we have undertaken

a strategic review of potential locations, utilising the

existing transmission network within the general

vicinity of Stronelairg wind farm.

Following standard criteria detailed within our Site

Selection Guidelines, an appraisal of strategic options

has been undertaken to assess the potential positive

and negative aspects of each possible location. This

process eliminated unsuitable sites on the grounds of

cost, engineering, and environmental considerations.

The Melgarve area is the most suitable for the

proposed substation due to proximity to the wind farm,

capacity of the existing transmission network and

potential to avoid significant environmental effects. A

detailed site selection process is being undertaken in

this area to identify a suitable site.

In combination with the substation site selection

process, we are undertaking a detailed assessment to

identify potential grid connection routes and options.

The grid connection route from the wind farm on-site

substation to the new substation site will be

approximately 8 km in length. A key consideration for

this grid connection will be whether to proceed with an

overhead (steel lattice tower) connection, or an

underground cable connection. Both options have a

number of factors to consider, such as constructability,

environmental impact and maintenance requirements.

As part of our consultation process we are seeking to

engage with members of the public, the local planning

authority and other key stakeholders to discuss these

issues before arriving at a preferred solution.

Who We Are Scottish and Southern Energy Power Distribution is part of the SSE plc group of companies. We own, maintain and invest in the electricity networks in the north of Scotland – the electricity transmission network (132 kV and above) and the electricity distribution network (below 132 kV). In Scotland, Scottish and Southern Energy Power Distribution is made up of two businesses:

Scottish Hydro Electric Transmission (SHE Transmission) owns and maintains the electricity transmission network across the north of Scotland, in some of the UK’s most challenging terrain; and Scottish Hydro Electric Power Distribution (SHEPD) operates the high and low voltage electricity network that distributes electricity to around 700,000 customers in north mainland Scotland and the Scottish islands.

Keeping the Lights On and Supporting Growth SHE Transmission owns around 5,000km of electricity transmission infrastructure which spans about 70% of the land mass of Scotland. Electricity networks like this provide a physical link between electricity generators and electricity users. We have three main objectives over the next decade:

To keep the lights on for our customers across the north of Scotland; To invest for a greener future; and To minimise, as far as possible, our impact on the environment.

As we are the only company that owns an electricity transmission network in the north of Scotland we are closely regulated by the energy regulator Ofgem. We are issued with a licence to operate and we must adhere to the terms of the licence. For this reason we are operated on a very separate basis to other SSE businesses. Our licence stipulates that we must develop and maintain an efficient, coordinated and economical system of electricity transmission. Our responsibilities also extend to ensuring that there is sufficient network capacity and a connection for developers who wish to export their generated electricity to the national grid. If a generator applies to connect to our network, we are required to facilitate this under the terms of our licence.

Our Approach

Throughout the life of our projects, we aim to work positively with local communities and keep people informed about what we are doing. This is particularly important when we are developing a proposal and we want to understand what local people think about our plans. We endeavour to take the time to discuss proposals with local community councils, encourage engagement from the wider community and listen to the feedback we receive. We will do our best to answer any questions and address issues or concerns that are raised with us. If our project progresses into construction, we will continue working closely with the local community to ensure that our work has as little impact on the lives of those living and working in the area and as many long term positive effects as possible.

Project Background

We are the licenced owner of the electricity transmission network in the north of Scotland. Operating under licence means that we have certain obligations that we must fulfil. These obligations include maintaining the existing network to ensure that the lights stay on and investing in the network to provide the infrastructure needed to allow generation developments to connect to it. The transmission network gathers energy from power stations, hydro-electric generation schemes and wind farms and carries it to areas where it is to be used. We work with the Transmission System Operator, National Grid, who is responsible for operating the transmission network across the whole of Great Britain, to make sure that power flows smoothly and reliably across our network. A request has been made to National Grid by the developer of Stronelairg wind farm to provide a grid connection to connect the wind farm. As the wind farm is in our licence area, we are responsible for providing the infrastructure needed to connect the wind farm. Stronelairg wind farm received consent from Scottish Ministers in June 2014. This consent is currently the subject of a judicial review. However, we must progress with proposals for the grid connection to ensure that we meet the proposed grid connection date. The grid connection will comprise a new 132 kV overhead line or underground cable together with a new substation. We are undertaking a route options appraisal and substation site selection exercise to identify a technically efficient and economic route and location for the grid connection, taking into account environmental factors to minimise any potential adverse impacts on the environment. We are here today seeking views from local residents about our proposals.

Project Description

The aim of the project is to provide a grid connection for Stronelairg wind farm to the transmission network. The proposed grid connection would comprise a new connection from the Stronelairg wind farm on-site substation, to a new 132 / 400 kV substation located adjacent, or with-in close proximity to, the existing transmission network. A new overhead line OR underground cable would be required to complete the connection between the substations. We are currently at an early stage of the project and are undertaking a number of studies to identify the most appropriate solution and location / route.

Substation Site Selection (Strategic)

We need to identify a suitable site to accommodate a new substation. In order to do this we have undertaken a strategic review of potential locations, utilising the existing transmission network within the general vicinity of Stronelairg wind farm. Potential options for the proposed substation are shown in the table and figure below. Following standard criteria detailed within our Site Selection Guidelines, an appraisal of these strategic options has been undertaken to assess the potential positive and negative aspects of each possible location. This process eliminated unsuitable sites on the grounds of cost, engineering, and environmental considerations. The Melgarve area is considered the most suitable for the proposed substation due to proximity to the wind farm, capacity of the existing transmission network and potential to avoid significant environmental effects. A detailed site selection process is being undertaken in this area to identify a suitable site.

Substation Option Comments Taken forward for further consideration

Fort Augustus Over 20 km from wind farm site Substation site currently at capacity Significant technical and environmental challenges with grid connection route due to topography and proximity to settlement

No

Foyers Over 25 km from wind farm site

No opportunities to extend substation site due to physical constraints

Grid connection would require routeing through challenging terrain Potential for grid connection route to impact upon properties and settlements

No

Other options along the Beauly to Denny overhead line

Options to the west, south west or south east of the wind farm considered but discounted due to extremely challenging topography

Potential for impact upon designated sites, such as the Cairngorms National Park and the Monadhliath SAC / SSSI

No

Melgarve Shortest and most direct route from wind farm to transmission network Sparsely populated area with good access from the local road network Grid connection would require routeing through challenging terrain

Yes

Plan Showing Strategic Sites Considered

Substation Site Selection (Detailed)

Following identification of the Melgarve area as a potential area for a new substation site, we are undertaking a detailed site selection exercise to identify the most suitable site to accommodate a new substation. The new substation site should be located as close to the existing transmission network as possible to minimise further connection requirements to the network. Substations should be located on relatively flat ground with good ground conditions (avoiding areas of deep peat). Areas where opportunities exist to visually screen the substation site are preferred in order to minimise potential landscape and visual impacts, and other environmental impacts should be minimised where possible. Environmental designations within the vicinity of the study area include the Cairngorms National Park, the Monadhliath Special Area of Conservation (SAC) / Site of Special Scientific Interest (SSSI), the River Spey SAC / SSSI and the Corrieyairack Pass Scheduled Ancient Monument. Potential impacts on these designated sites, as well as other environmental considerations, should be minimised as far as practicable. Potential site options are being investigated throughout the study area. Initial indications suggest that a substation site within the area marked as Option B on the plan below could be feasible from a technical and environmental perspective. Throughout the life of our projects, we aim to work positively with the local community, stakeholders and interested parties. We welcome comments on our proposals in order to ensure that local issues are taken into account when designing projects.

Substation Site Selection Plan

Substation - Consenting Process

Consent for construction of the new substation would likely be sought by way of a planning application to The Highland Council under the Town and Country Planning (Scotland) Act 1997. Due to the size of the substation being in excess of 2 hectares, the development falls within the category of ‘Major Development’ under the Town and Country Planning (Hierarchy of Development) (Scotland) Regulations 2009 (The Hierarchy Regulations). The site will be the subject of a rigorous environmental appraisal to assess potential impacts on factors such as ecology and ornithology; soils and hydrology; cultural heritage; habitat and flora; and landscape character and visual amenity. The appraisal would evaluate potential environmental impacts of the preferred substation site and provide appropriate measures to mitigate against such impacts as appropriate.


6

Substation Design Options

Gas Insulated Switchgear (GIS)

Air Insulated Switchgear (AIS)

The new substation would either comprise Air Insulated Switchgear (AIS), or Gas Insulated Switchgear (GIS). Within an AIS, the live electrical equipment uses air as the insulating medium. This results in a larger footprint due to the clearance distances required between electrical equipment. Within a GIS, live electrical equipment uses a special gas as the insulating medium, usually SF6 gas. Live electrical equipment is enclosed in a building, rather than exposed, and the use of the gas reduces the clearance distances required between electrical equipment. This results in a smaller footprint for a GIS compared to an AIS. The figures below provide a comparison of these two options.


7

Grid Connection - Overhead or Underground? In combination with the substation site selection process, we are undertaking a detailed assessment to identify potential grid connection routes and options. The grid connection route from the wind farm on-site substation to the new substation site will be approximately 8 km in length. A key consideration for this grid connection will be whether to proceed with an overhead (steel lattice tower) connection, or an underground cable connection. Both options have a number of factors to consider, such as constructability, environmental impact and maintenance requirements. As part of our consultation process we are seeking to engage with members of the public, the local planning authority and other key stakeholders to discuss these issues before arriving at a preferred solution.

Grid Connection - Route Selection As part of the route options appraisal, a number of corridors have been identified which are potentially suitable for either an underground cable or overhead line connection. The approach we are taking in identifying and assessing possible corridors capable of accommodating a new grid connection is consistent with national guidance on the routeing of steel lattice towers (if an overhead option were taken forward). The guidance recommends a hierarchical approach to routeing which avoids major areas of highest amenity first, then avoids smaller areas of high amenity, and which then considers factors such as backdrop, woodland and orientation. Other factors such as topography, peat depth and habitat type are also considered. Using this approach, four main grid connection corridors have been identified, as shown in the figure below. These options will be subject to more detailed technical and environmental surveys in order to identify a preferred route.

Grid Connection - Consenting Process

An overhead line would require consent under Section 37 of the Electricity Act 1989 and would be subject to determination by The Scottish Ministers. Permission to install an underground cable would be subject to discussion with The Highland Council. Either option would be the subject of a rigorous environmental appraisal which would assess impacts on ecology and ornithology; soils and hydrology; cultural heritage; habitat and flora; and landscape character and visual amenity. The appraisal would evaluate potential environmental impacts of the preferred grid connection route and provide appropriate measures to mitigate against such impacts as appropriate. We will continue to work with environmental consultants and grid connection engineers to identify a technically feasible and economically viable route which gives rise to:

The least disruption to the amenity of people living and working in the area; The least impact on the physical and natural environment, and on nationally important species, habitats and cultural assets; and The least disruption to current land use and management practices.

APPENDIX 5: EXHIBITION LEAFLET (FEBRUARY 2015)

About SSE Power Distribution

Project Description

As we are the only company that owns an electricity

transmission network in the north of Scotland we are

closely regulated by the energy regulator Ofgem.

Our licence stipulates that we are obliged to develop and

maintain an efficient, coordinated and economical

system of electricity transmission.

Our responsibilities also extend to ensuring that there is

sufficient network capacity and a connection for

developers who wish to export their generated electricity

to the national grid.

Throughout the life of our projects, we aim to work

positively with local communities and keep people

informed about what we are doing. This is particularly

important when we are developing a proposal and we

want to understand what local people think about our

plans.

Scottish and Southern Energy Power Distribution is

part of the SSE plc group of companies. We own,

maintain and invest in the electricity networks in the north

of Scotland – the electricity transmission network (132

kV and above) and the electricity distribution network

(below 132 kV). In Scotland, Scottish and Southern

Energy Power Distribution is made up of two

businesses:

Ÿ Scottish Hydro Electric Transmission (SHE

Transmission) owns and maintains the electricity

transmission network across the north of Scotland,

in some of the UK’s most challenging terrain; andŸ Scottish Hydro Electric Power Distribution

(SHEPD) operates the high and low voltage electric-

ity network that distributes electricity to around

700,000 customers in north mainland Scotland and

the Scottish islands.

A request has been made to National Grid by the

developer of Stronelairg wind farm to provide a grid

connection to connect the wind farm. As the wind farm is

in our licence area, we are responsible for providing the

infrastructure needed to connect the wind farm.

The proposed grid connection would comprise two key

elements:

Ÿ A new 400 / 132 kV substation located adjacent to

the existing transmission network; and

Ÿ An underground cable to connect the wind farm to

the new substation.

We have undertaken a route options appraisal and

substation site selection exercise to identify the route

and location for the grid connection, taking into

account, amongst other criteria, environmental factors

to minimise any potential adverse impacts on natural

and cultural heritage resources. We have identified a preferred substation site and

underground cable route and are currently completing

our technical and environmental studies. We aim to

submit a planning application for the substation site

during late Spring 2015.

We welcome comments on our proposals in order to

ensure that local issues are taken into account when

designing projects.

Stronelairg Wind Farm: Location

Following a detailed substation site selection exercise,

we have identified a suitable site for developing a

substation within the Melgarve / Garva Bridge area.

This was considered the most suitable due to proximity

to the wind farm, capacity of the existing transmission

network and potent ia l to avo id s ign ificant

environmental effects. The substation would comprise Gas Insulated

Swi tchgear and would have a footpr in t o f

approximately 165m x 125m. Opportunities exist to

develop a landscaping strategy that would help screen

the substation from nearby receptors.

Consent for construction of the new substation will be

sought by way of a planning application to The

Highland Council under the Town and Country

Planning (Scotland) Act 1997. Due to the size of the

substation being in excess of 2 hectares, the

development falls within the category of 'Major

Development' under the Town and Country Planning

(Hierarchy of Development) (Scotland) Regulations

2009.

A key consideration for this grid connection has been

whether to proceed with an overhead line (steel lattice

tower), or an underground cable. We have undertaken a series of technical and

environmental studies to enable us to reach a decision

on the method of connection, and have consulted

widely with the local planning authority, key

stakeholders and the public. Following our survey work and taking on board

comments received during our consultation exercise,

we have decided to proceed with an underground

cable connection.

Underground electricity cables are deemed to be

permitted development (with planning permission

granted for any such permitted development) under

The Town and Country Planning (General Permitted

Development) (Scotland) Order 1992 (“GPDO”),

subject to certain exceptions such as avoidance of

significant impacts on designated sites. Permission to

install an underground cable would be subject to

discussion with The Highland Council.

Who We Are Scottish and Southern Energy Power Distribution is part of the SSE plc group of companies. We own, maintain and invest in the electricity networks in the north of Scotland – the electricity transmission network (132 kV and above) and the electricity distribution network (below 132 kV). In Scotland, Scottish and Southern Energy Power Distribution is made up of two businesses:

Scottish Hydro Electric Transmission (SHE Transmission) owns and maintains the electricity transmission network across the north of Scotland, in some of the UK’s most challenging terrain; and Scottish Hydro Electric Power Distribution (SHEPD) operates the high and low voltage electricity network that distributes electricity to around 700,000 customers in north mainland Scotland and the Scottish islands.

Keeping the Lights On and Supporting Growth

SHE Transmission owns around 5,000km of electricity transmission infrastructure which spans about 70% of the land mass of Scotland. Electricity networks like this provide a physical link between electricity generators and electricity users. We have three main objectives over the next decade:

To keep the lights on for our customers across the north of Scotland; To invest for a greener future; and To minimise, as far as possible, our impact on the environment.

As we are the only company that owns an electricity transmission network in the north of Scotland we are closely regulated by the energy regulator Ofgem. Our licence stipulates that we are obliged to develop and maintain an efficient, coordinated and economical system of electricity transmission. Our responsibilities also extend to ensuring that there is sufficient network capacity and a connection for developers who wish to export their generated electricity to the national grid.

Our Approach

Throughout the life of our projects, we aim to work positively with local communities and keep people informed about what we are doing. This is particularly important when we are developing a proposal and we want to understand what local people think about our plans. We endeavour to take the time to discuss proposals with local community councils, encourage engagement from the wider community and listen to the feedback we receive. We will do our best to answer any questions and address issues or concerns that are raised with us. If our project progresses into construction, we will continue working closely with the local community to ensure that our work has as little impact on the lives of those living and working in the area and as many long term positive effects as possible.

Project Background

We are the licenced owner of the electricity transmission network in the north of Scotland. Operating under licence means that we have certain obligations that we must fulfil. These obligations include maintaining the existing network to ensure that the lights stay on and investing in the network to provide the infrastructure needed to allow generation developments to connect to it. The transmission network gathers energy from power stations, hydro-electric generation schemes and wind farms and carries it to areas where it is to be used. We work with the Transmission System Operator, National Grid, who is responsible for operating the transmission network across the whole of Great Britain, to make sure that power flows smoothly and reliably across our network. A request has been made to National Grid by the developer of Stronelairg wind farm to provide a grid connection to connect the wind farm. As the wind farm is in our licence area, we are responsible for providing the infrastructure needed to connect the wind farm. We have undertaken a route options appraisal and substation site selection exercise to identify the route and location for the grid connection, taking into account, amongst other criteria, environmental factors to minimise any potential adverse impacts on natural and cultural heritage resources. We want to seek views from local residents about our proposals.

Project Description

The aim of the project is to provide a grid connection for Stronelairg wind farm to the transmission network. The proposed grid connection would comprise two key elements:

A new 400 / 132 kV substation located adjacent to the existing transmission network; and An underground cable to connect the wind farm to the new substation.

We have identified a preferred substation site and underground cable route and are currently completing our technical and environmental studies. We aim to submit a planning application for the substation site during late Spring 2015.

Substation Site Selection (Strategic)

In order to identify a suitable site to accommodate a new substation, we initially undertook a strategic review of potential locations utilising the existing transmission network within the general vicinity of Stronelairg wind farm. Potential options considered are shown in the table and figure below. An appraisal of these strategic options was undertaken to assess the potential positive and negative aspects of each possible location. This process eliminated unsuitable sites on the grounds of economics, engineering, and environmental considerations. The Melgarve / Garva Bridge area was considered the most suitable for the proposed substation due to proximity to the wind farm, capacity of the existing transmission network and potential to avoid significant environmental effects. A detailed site selection process was then undertaken in this area.

Substation Option Comments Taken forward for further consideration

Auchterawe Substation Fort Augustus

Over 20 km from wind farm site Auchterawe substation site currently at capacity and significant additional redevelopment would be required to accommodate connection. This could also result in additional reinforcement of the transmission network required around the Fort Augustus area Potential for significant technical and environmental challenges with grid connection route due to topography, proximity to settlement, and complexities of Caledonian Canal crossing Technical challenges and limitations with underground cable over this length (20km) Overall, not an economical or efficient solution

No

Foyers Substation Over 25 km from wind farm site No viable opportunity to extend Foyers substation site due to physical constraints Requirement for technically challenging rebuilding of the Foyers-Knockngael 275 kV overhead line Grid connection would require routeing through challenging terrain with potential for significant technical and environmental challenges Potential for grid connection route to impact upon properties and settlements Overall, not an economical or efficient solution

No

Other options along the Beauly-Denny overhead line

Options to the west, south west or south east of the wind farm considered but discounted due to extremely challenging topography Potential for impact upon designated sites, such as the Cairngorms National Park and the Monadhliath SAC / SSSI

No

Melgarve / Garva Bridge

Shortest and most direct circuit route from wind farm to transmission network Sparsely populated area with good access from the local road network Grid connection would require routeing through challenging terrain Suitable location relative to Beauly-Denny overhead line to accommodate output from the wind farm without requirement for further reinforcement of the transmission network.

Substation Site Selection (Detailed)

Following identification of the Melgarve area as a potential area for a new substation site, we undertook a detailed site selection exercise to identify the most suitable site to accommodate a new substation. The new substation site needs to be located as close to the existing transmission network as possible to minimise further connection requirements to the network. It is also important to identify an area of relatively flat ground with good ground conditions. Areas where opportunities exist to visually screen the substation site are considered in order to minimise potential landscape and visual impacts, and other environmental impacts are minimised where possible. Environmental designations within the vicinity of the study area include the Cairngorms National Park, the Monadhliath Special Area of Conservation (SAC) / Site of Special Scientific Interest (SSSI), the River Spey SAC / SSSI and the Corrieyairack Pass Scheduled Ancient Monument. Potential impacts on these designated sites, as well as other environmental considerations, are minimised as far as practicable. Considering these technical and environmental factors, the area marked on the plan near Garva Bridge was identified as the preferred site for the proposed substation. Throughout the life of our projects, we aim to work positively with the local community, stakeholders and interested parties. We welcome comments on our proposals in order to ensure that local issues are taken into account when designing projects.

Substation Site Selection Plan

Substation - Consenting Process

Consent for construction of the new substation will be sought by way of a planning application to The Highland Council under the Town and Country Planning (Scotland) Act 1997. Due to the size of the substation being in excess of 2 hectares, the development falls within the category of ‘Major Development’ under the Town and Country Planning (Hierarchy of Development) (Scotland) Regulations 2009. The site will be the subject of an environmental appraisal to assess potential impacts on factors such as ecology and ornithology; soils and hydrology; cultural heritage; habitat and flora; and landscape character and visual amenity. The appraisal would evaluate potential environmental impacts of the preferred substation site and provide appropriate mitigation measures.

Substation Design Options

Indicative 3D Model of Substation (GIS)

During analysis of the design options available to us for the new substation, we considered two principle options:

A substation comprising Air Insulated Switchgear (AIS). Within an AIS, the live electrical equipment uses air as the insulating medium. This results in a larger footprint due to the clearance distances required between electrical equipment. Initial design studies suggested the footprint could be approximately 260m x 260m; or

A substation comprising Gas Insulated Switchgear (GIS). Within a GIS, live electrical equipment uses a special gas as the insulating medium, usually SF6 gas. Live electrical equipment is enclosed in a building, rather than exposed, and the use of the gas reduces the clearance distances required between electrical equipment. This results in a smaller footprint for a GIS compared to an AIS. Initial design studies suggest the footprint could be approximately 165m x 125m.

On reviewing the two options we determined that a substation comprising GIS would be the most appropriate solution for this site. The indicative 3D model below gives an impression of the layout of the substation when viewed from above. Landscape mitigation opportunities to minimise potential landscape and visual impacts are discussed on the following board.

Substation Landscape Mitigation Opportunities

Indicative Plan of Substation

The plan below shows the substation platform within the context of the Proposal of Application Notice boundary. The plan also demonstrates the potential opportunities that exist for landscaping around the substation to minimise potential landscape and visual impacts of the substation to the surrounding area. Landscaping opportunities at this site could include the use of bunds and mixed woodland screen planting. As we develop our final substation design, we will work closely with our project landscape architects to ensure a suitable landscape strategy is proposed at this site.

Substation Site — Environmental Information

Draft Zone of Theoretical Visibility

The new substation site would connect to Tower number 64 on the new Beauly-Denny overhead line, 2 km west of Garva Bridge, as shown in the photograph below. A series of environmental surveys have been carried out at the site to date, a summary of these surveys is provided below.

Environmental survey summary: Habitat surveys classify the site as located partly on an area of wet heath and partly on an area of felled plantation forestry. This is an area of low conservation value. No sign of protected species identified within the immediate vicinity of the substation site. No nesting birds identified within the immediate vicinity of the substation site. Peat probing results show that the substation site would be located on shallow peat. The substation site is not located close to watercourses and SEPA flood risk mapping demonstrates the area is not at risk from flood-ing. Cultural heritage surveys have not identified any sites of significance within the vicinity of the substation site. Scheduled sections of General Wade’s Road would not be physically impacted by the development and visibility of the substation from the road would be limited. Noise sensitive receptors (properties at Garvamore, Garvabeg and Drummin Bothy) are all over 2.5km from the substation site. Potential impacts during operation are therefore expected to be negligible. A draft Zone of Theoretical Visibility has been produced to demonstrate the potential visibility of the substation. This shows that visibility would be relatively limited, particularly from properties in the wider area and important recreational routes.

Grid Connection - Overhead or Underground?

In combination with the substation site selection process, we have undertaken a detailed assessment to identify potential grid connection routes and options. A key consideration for this grid connection has been whether to proceed with an overhead line (steel lattice tower), or an underground cable. Both options have a number of factors to consider, such as constructability, environmental impact and maintenance requirements. We have undertaken a series of technical and environmental studies to enable us to reach a decision on the method of connection, and have consulted widely with the local planning authority, key stakeholders and the public. Following our survey work and taking on board comments received during our consultation exercise, we have decided to proceed with an underground cable connection.

Grid Connection - Route Selection

We identified a number of potential route corridors for the underground cable connection. Our approach considered potential environmental impacts on habitats and protected species, birds, peat depth, impact on watercourses and cultural heritage, as well as consideration of potential landscape and visual impacts. Our preferred route, shown on the figure below, has sought to minimise these impacts where possible, whilst being technically and economically achievable.

Grid Connection - Consenting Process

Underground electricity cables are deemed to be permitted development (with planning permission granted for any such permitted development) under The Town and Country Planning (General Permitted Development) (Scotland) Order 1992 (“GPDO”), subject to certain exceptions such as avoidance of significant impacts on designated sites. We are undertaking an environmental appraisal which will assess impacts on ecology and ornithology; soils and hydrology; cultural heritage; habitat and flora; and landscape character and visual amenity. The appraisal would provide appropriate measures to mitigate against such impacts. Permission to install an underground cable would be subject to discussion with The Highland Council.
