We have successfully completed an £8.4million upgrade of our Kilmarnock Town substation, helping to boost capacity and resilience in the region.
The UK’s electricity demand is set to double by 2050 as more homes and businesses have their power needs, including heating and transport, met by electricity. The upgrade of Kilmarnock town substation will help more locally generated power connect to the grid and be transported across the country – providing more green electricity to support everyday lives.

The £8.4 million investment is part of wider work to boost the transmission network across the UK, helping to unlock economic growth and increase energy security, all whilst moving the country towards an all-electric future.
Work on the substation started in March 2023 and focused on replacing two aging transformers and upgrading other substation equipment that had reached the end of its operational life, including switching gear and circuit breakers.
Through this modernisation, the East Ayrshire substation now boasts increased capacity to meet future energy demands and allows more communities to benefit from secure and reliable supplies.
This investment to support green energy transmission aligns with the UK’s ambition to achieve a clean power system by 2030 and net zero emissions by 2050.
Jason Mcinally, Project Manager at SP Energy Networks said "With the completion of our Kilmarnock Town substation upgrade project, we’re improving the reliability of the power supply for homes and businesses in Kilmarnock and surrounding areas.
“Kilmarnock is now better equipped than ever to meet the demands of a low-carbon future. For decades to come the region will play a key role in renewable energy generation, helping more people across the UK to access clean, green, secure energy.
“I’d like to thank our hard-working team and contractors who helped make this transformation happen and all with minimal disruption to the local community throughout.”
