What is the Inveraray-Crossaig project?

The aim of the project is to reinforce the existing transmission network between Inveraray and Crossaig to enable renewable energy projects to connect to the electricity network, and to ensure security of supply. The main elements of the project are as follows:

  • Construction of a new 275kV overhead line, initially operated at 132kV between Inveraray and Crossaig (connecting to the new Craig Murrail Substation)
  • Extend the existing connection from Port Ann to the new overhead line.
  • Decommissioning/removal of the existing 132kV transmission line between Inveraray and Crossaig.

Requests have been made to National Grid by a number of wind farm developers for transmission grid connections in the Argyll and Kintyre area. We are responsible for providing the infrastructure required to connect the wind farms to the electricity network.

Why is the project required?

As the transmission licence holder in the north of Scotland we have a duty under Section 9 of the Electricity Act 1989 to facilitate competition in the generation and supply of electricity. We have obligations to offer non-discriminatory terms for connection to the transmission system, both for new generation and for new sources of electricity demand.
The aim of the project is to enable renewable energy to connect to our transmission network. Under our Network Operators Licence this connection should be efficient, co-ordinated and economic, whilst having the least possible impact on the environment.

What does the Inveraray-Crossaig project compromise?

In order to provide the required increase of capacity, it is proposed to replace the existing 132kV overhead line between Inveraray switching station to Crossaig substation with a 275kV overhead line. It is intended that the new line will be initially operated at 132kV but with capacity to operate at 275kV, and so it is being constructed as being 275kV capable.

The main elements of the project are as follows:

  • Connection to the existing switching station in Inveraray 
  • Construction of a new overhead line capable of operating at 132 kV or 275 kV between Inveraray and Crossaig
  • Decommissioning andremoval of the existing 132 kV transmission line between Inveraray and Crossaig; and
  • Connection to the 132 kV substation at Crossaig

How do we select a final route for the overhead line?

Since the public introduction of the project in 2014, we have been working with a multi disciplinary team of consultants to identify a corridor within which a new overhead line could be routed. Public exhibitions were held in March 2016 to consult with interested parties on the proposed route corridor.

The existing overhead line runs from Inveraray switching station to the new substation at Crossaig and is approximately 83km in length.

It runs easterly through Mid Argyll, adjacent to Loch Fyne and into the Kintyre Peninsula. The line passes through or in close proximity to areas such as Minard, Port Ann, Lochgilphead, Inverneil and Tarbert. Past Tarbert the line is further inland, passing through Whitehouse and ending at Crossaig.

The proposed route corridor that has been identified is adjacent to the existing line in many areas. In defining the proposed route corridor, we considered potential impacts to properties, settlements and other environmental factors. In some locations, the proposed route corridor deviates from the alignment of the existing line to minimise potential impacts on these receptors where possible.

Within that corridor, we are currently working to identify a preferred route alignment. This will include an aerial survey of the proposed route corridor which will aid with the detailed design of the project. With this survey data, the team will begin the next phase of design which will include placement of towers for the new overhead line.

In addition to the aerial survey, there will be ground level surveys taking place to establish the access requirements to accommodate the construction phase of the project. Consultation on the preferred route alignment will be finalised and an accompanying Environmental Impact Assessment and an application under Section 37 of the Electricity Act 1989 will be submitted to the Scottish Government Local Energy and Consents.

Why are the proposals for the upgrade of the electricity network between Inveraray and Crossaig being promoted?

The current transmission infrastructure has developed over many years; originally it was built to connect the demand centres that are spread around the north of Scotland and the remote  the remote  multiple hydro electric power stations developed mainly in the 1950s and 60s. However, with the recent increase in renewable generation, in particular wind generation, the pattern of electricity supply and consumption has changed dramatically. As a consequence parts of the transmission network now need substantial upgrading as we seek to meet our licence obligations to develop and maintain an economic, efficient and coordinated system as well as ensuring security of supply to electricity consumers.

Following detailed analysis of required system transfers and comparing this with actual network capacity, we have identified the need to upgrade the transmission network between Inveraray switching station and Crossaig substation.

The need to upgrade the network between Inveraray and Crossaig is reviewed by our transmission business and National Grid (in its role as Great Britain system operator) on an annual basis, and the anticipated timing of the Project may change in response to changing economic signals from a range of electricity generation and demand scenarios.

What will happen if renewable energy projects cancel their connection request?

We have an obligation to respond to the demand for connections that are contracted to connect to the electricity transmission network or that are forecasted to connect. The generation market is kept under annual review. If a developer has a contracted connection date, we must work to that date until the developer modifies its connection application or withdraws it. For these projects, our transmission business and National Grid as transmission system operator are monitoring the activities and progress of many renewable developments including onshore and offshore wind, hydro, pumped storage, wave, tidal, solar and existing generation plant that may increase or decrease their contracted output to the grid. 

Why can't the replacement line follow exactly the same route as the existing overhead line?

Construction of the new overhead line will take approximately three years and during that time the existing overhead line must remain operational to provide power to customers.. Therefore it is not possible to build over the existing overhead line which at a minimum must be kept 50m away to meet operational regulations.

There will be places where the new line must cross the existing line; however the timeframes will be kept to a minimum and contingency plans shall be put in place to overcome the technical challenges.

How do we consult on our proposals?

As a responsible developer, we believe that it is important to seek public opinion on our proposals and take that feedback into consideration when developing their projects. Consultation events are therefore held at defined stages of project development in various locations along the route of the proposed line. These consultation events are widely publicised in order to ensure that as many people as possible are made aware of them. 

Prior to consultations held in March 2016 on the preferred route corridor, the services of a mailing company were utilised to mail drop over 10,000 information notices to houses in local postcodes. Elected members and Community Councils also received information notifications via post. The events were advertised in the local newspapers and posters were placed throughout the local communities. The events were also advertised via our social media platforms and on our dedicated project webpage.

A similar approach will be adopted to ensure the effective publicising of future consultation events

 

Consultation Close Date

SSEN would like to extend thanks to all who took the time to attend our recent consultation events held between 26 September - 4 October 2017 at Inveraray, Ardrishaig, Skipness and Carradale. We are keen to recieve as much feedback as possible prior to Friday 3rd November and would encourage all interested parties to submit comments before this date. This can be done via the link on the left hand side of the Project Overview page or by contacting the Community Liaison Manager direct.

Consultation Document

You can find the Inveraray to Crossaig Consultation Document in the "Project Documentation" section, titled ‘Inveraray to Crossaig 275 kV OHL Alignment Selection Consultation Document’. The associated Figures are also available for download. The Consultation Document and Figures provide a summary of the alignment choices considered during the design process which has been carried out since the last public exhibition in March 2016. The alignment choices we have considered are included, along with the reasons for our choice of Preferred Alignment. This document was provided to the Scottish Government’s Energy Consent Unit and Statutory Consultees in June 2017.

Scoping Report

We have sought a scoping opinion from the Scottish Government for the proposed Inveraray-Crossaig overhead line. Copies of the scoping request and supporting information can be accessed within the project documentation tab. The purpose of the scoping request is to establish the scope of the Environmental Impact Assessment Report.

Project Newsletter

As the project team continue to establish a route alignment for the replacement overhead line, further consultation on the Inveraray-Crossaig project is now scheduled for Autumn 2017. However, as we aim to ensure that the local community are well informed of the work that has been carried out since the last public consultation; an in-depth project newsletter shall be published in the summer time. The newsletter shall involve details of the survey work undertaken, changes to the initial proposals and further details of the environmental constraints currently being considered. There will also be an opportunity to provide feedback on the newsletter which will be digitally uploaded to the project webpage. If you would like to receive a hard copy of the newsletter once published, please email the project Community Liaison Manager to register your interest and provide an address.

Consultation Rescheduling

During the most recent public consultation events held for the Inveraray-Crossaig Overhead Line Reinforcement Project in March 2016, the indicative project timeline displayed further consultation events scheduled for August 2016. In late summer the project underwent a period of review resulting in a postponement of consultation. We are continuing to progress with the project and are currently in the process of identifying a route alignment. Public consultation events displaying the route alignment are intended to be held in the first quarter of 2017. Once dates are selected in the New Year the events will be publicly advertised and local communities informed. If you have any questions regarding the project or further consultation dates, please do not hesitate to contact our Community Liaison Manager, Kelly Scott.
