SP Energy Networks has launched a public consultation on plans to route a new overhead line to connect the proposed Callisterhall Wind Farm, near Winterhope Reservoir east of Lockerbie, to the Gretna substation in Dumfries & Galloway. A 15km 'preferred route’ has been identified for feedback.
The developer-funded connection would be built using dark brown wooden poles, 14–16 metres high and spaced roughly 65–100 metres apart. It is intended to bring more renewable power onto the network to meet rising electricity demand and support low‑carbon technologies such as electric vehicles and heat pumps.
Residents can view proposals, meet the project team and ask questions at a local drop‑in on Tuesday 2 December, 2–7pm, at Chapelknowe Village Hall, Canonbie DG14 0YF. Further information is also available online at: callisterhall_wind_farm_connection
The consultation runs from 1 December 2025 to 16 January 2026. Feedback can be provided via an online form (live from 1 December), by post to: Callisterhall Wind Farm Connection, Land and Planning Team, SP Energy Networks, 55 Fullarton Drive, Glasgow, G32 8FA, or by email to: callisterhallconnectionproject@spenergynetworks.co.uk
Input from this first round, alongside environmental survey findings, will inform the final proposed route. SP Energy Networks anticipates further public engagement in late 2026 and plans to submit a consent application to the Scottish Government’s Energy Consents Unit in spring 2027.
A spokesperson for SP Energy Networks said: "We’re delivering the biggest upgrade the grid has ever seen – ensuring our electricity network supports a cleaner and greener future for all – and working with the communities we serve to deliver the best possible outcomes is at the heart of this.
"The project is currently in its early stages, and we would like to hear your views on the preferred route running from the proposed Callisterhall Wind Farm to the substation at Gretna.
"There is real value and benefit in communities taking part in consultations and we hope that people take the time to look at the proposals and feedback or if they can, come along to the community drop-in."
