Rogerhill Solar and Battery Energy Storage System 132kV Grid Connection

Scotland is a world leader in the fight against climate change. We are producing more clean, green energy than ever before, and we need to strengthen the transmission network so we can get it to the homes, businesses, hospitals and public services that need it.

As part of their commitments to tackling climate change, the Scottish and UK Governments have set legally binding targets to reach net zero in their greenhouse gas emissions by 2045 in Scotland and by 2050 in the rest of the UK. In delivering net zero, the demand for electricity is forecast to grow rapidly over the next few years, with electric vehicles replacing petrol and diesel, and increased electrification of heating, industry and transport networks. In addition, the electricity generation system is undergoing transformational change with traditional power stations being replaced by renewable sources, i.e., hydro and wind power etc.

As an electricity transmission licence holder, SP Transmission plc (SPT), a wholly owned subsidiary of SP Energy Networks (SPEN), is responsible for the transmission of electricity in central and southern Scotland and has a legal duty under the Electricity Act 1989 to provide grid connections to new electricity-generating developments. We have been contracted via the National Energy System Operator (NESO) to provide a connection from the proposed Rogerhill Solar and Battery Energy Storage System 132kV Grid Connection, located approximately 0.5 km west of Blackwood, to Coalburn North substation, located approximately 2 km south of Coalburn, within the South Lanrkshire Council area.

The Proposal

The proposed 132kV connection between Rogerhill Solar and Battery Energy Storage System 132kV Grid Connection and Coalburn North involves the construction of twin overhead lines (OHL) over a distance of approximately 7 km.

SPEN’s policy is to seek a continuous OHL for transmission connections, in line with statutory license requirements.

The final design, including how the connection enters each substation, is still under development and may include terminal poles or a section/sections of UGC.

Rogerhill Environmental Planner

We are consulting the public on our proposals between 29^th January 2026 and 26^th February 2026.

You can view physical consultation materials and share feedback at the following event:

Thursday 29^th January at, The Fountain Community Centre, 11 Abbeygreen, Lesmahagow, Lanark ML11 0HD, between 3PM and 8PM.

You can also share your views by email at rogerhill.connection@spenergynetworks.co.uk or write to:

Feedback can also be provided via our online feedback form (opens in a new window)

What happens next?

Comments received during the consultation on our preferred route will be taken into consideration alongside findings of environmental surveys to help identify the final proposed route.

We are planning to hold a second round of consultation in 2026 to share how we have taken on board your comments and seek feedback on our final proposals before we submit a Section 37 application to the Scottish Government Energy Consents Unit to seek permission for the development.

FAQs

Who are SP Energy Networks?

SP Energy Networks is part of the Scottish Power Group. We are responsible for the transmission and distribution of electricity in Central and Southern Scotland (through Scottish Power Transmission), and, through SP Manweb, the distribution network in North Wales, Merseyside, Cheshire and North Shropshire. Our role is to maintain, operate and invest in our network to secure a safe, reliable, and economic service for current and future consumers.

What statutory obligations does SP Energy Networks have?

Our statutory obligations are set out in the Electricity Act 1989 and in our transmission licence. We must develop and maintain an efficient, coordinated, and economical transmission system in accordance with security and quality of supply standards. We must offer to connect new power generators to the system and make sure any work we do keeps disturbance to the natural and built environment and the people who live in it, work in it, or enjoy it, to a minimum.

Who regulates SP Energy Networks?

We are regulated by Ofgem (Office of the Gas and Electricity Markets), an independent national regulatory body. Further information about Ofgem is available at:

www.ofgem.gov.uk

What exactly are you proposing?

The proposed 132kV connection between Rogerhill Solar and Battery Energy Storage System 132kV Grid Connection and Coalburn North substation involves the construction of overhead lines (OHL) over a distance of approximately 7 km. The final design, including how the connection enters each substation, is still under development and may include terminal poles or a section/sections of UGC.

How much will the project cost?

We are at an early stage of project development, and we won’t be able to cost the project fully until we have a definite proposal.

How are you consulting local people?

We are planning two rounds of public consultation before we submit our Section 37 application to Scottish Government’s Energy Consents Unit.

First round consultation dates:

Date	Venue	Time
Thursday 29th January 2026	The Fountain Community Centre, 11 Abbeygreen, Lesmahagow, Lanark ML11 0HD	3PM - 8PM

If you are not able to attend the public consultation event, there are other ways you can provide feedback:

Can you tell me more about Electric and Magnetic Fields (EMFs)?

SPEN follows the advice of independent experts, and all overhead lines comply with UK Government Policy, which is based upon adoption of the 1998 guidelines published by the International Commission on Non-Ionising Radiation Protection (ICNIRP). This policy was reaffirmed in a Written Ministerial Statement in October 2009.

The guidelines state that the levels of field required to achieve compliance are as follows:

Electric Field – 9kV/m

Magnetic Field – 360 microtesla

There has been a lot of research into whether electric and magnetic fields have any effect on health, and over £300m and many decades has been invested in investigating this issue around the world. Research still continues but the balance of scientific evidence to date suggests that EMFs do not cause disease.

We have dedicated EMF resources to assist the public and to provide further information, including, if appropriate, home visits and measurement of electric and magnetic fields. Copies of the leaflet “EMFs – the facts” were available at our public consultation events. We also directed people to the website www.emfs.info for further information.

Electric and Magnetic fields – The Facts is a document produced by the UK electricity industry.
