SP Energy Networks sets out updated proposals for major grid upgrade in Fife

09/06/2026

We have published revised plans for essential upgrades to the electricity transmission network in Fife.

The proposals are part of our long‑term investment to unlock regional economic growth, increase capacity and ensure a secure and reliable power supply for future generations.

As electricity demand across Scotland is expected to double by 2050, we are proposing to extend Mossmorran substation near Cowdenbeath and increase the voltage of existing overhead transmission lines in Fife.

These upgrades will create additional capacity on the network, enabling more renewable energy to be transported efficiently from where it is generated to homes and businesses across the country.

We are seeking feedback from local communities on the updated proposals and comments received during this consultation will help shape the final design for the substation layout, access, drainage and landscaping.

Local residents are invited to meet the project team, view the updated plans and ask questions at the following community drop-in events:

Tuesday 23 June, 2pm–7pm Auchtertool Village Hall, Main Street, Auchtertool, KY2 5XW

Wednesday 24 June, 11am–4pm Crossgates Royal British Legion, 60 Main Street, Crossgates, Cowdenbeath, KY4 8AW

Anyone who cannot make it along on the day can ask any questions or share their views via the TKUP Project website: https://www.spenergynetworks.co.uk/pages/tkup.aspx

Much of Scotland’s transmission network was built between 50 and 100 years ago. While it has evolved over time, sections of the network are now nearing operational limits at a time when more wind, solar and battery storage projects are seeking to connect.

To accommodate this growth, the voltage of overhead lines between Tealing and Kincardine will increase from 275kV to 400kV. This requires upgrades at Mossmorran and Westfield substations, along with a new substation at Conland, north of Leslie.

Ian Page, Project Manager for the Mossmorran substation upgrade said, “Following the previous consultation, we are giving the community a further opportunity to review the revised proposals and make comments before we finalise the design that we will submit for planning consent.”

“Local feedback is a crucial part of developing our designs and it is important that we listen and take this on board where we can, to create the optimal design for the expansion of Mossmorran facility and get more clean, green electricity into the grid network.”
