SP Energy Networks has announced the successful completion of a key upgrade of overhead powerlines in Ayrshire to help enable growth and support the transition to net zero in the area.

The £9.5 million project – connecting Chipperlaigan and Ayr substations – started in 2021 and involved comprehensive rewiring and steel works on 29 towers spanning more than five miles.

The project is a stepping stone in the right direction for East and South Ayrshire as the areas progress towards the Scottish Government target of becoming net zero by 2045.


The refurbished route, an integral part of the energy infrastructure in Ayrshire, has undergone a significant transformation as part of our commitment to modernise and enhance our network.

Originally constructed in 1966, the 275 kV double circuit overhead line serves as a vital link in the regional power grid. The modernisation of the network will help support the growing demand for green energy solutions such as electric vehicles and heat pumps.

Pearse Murray, SP Transmission Director at SP Energy Networks, said: "This upgrade will help ensure people across Ayrshire can benefit from a modern and resilient electricity network that will make it easier than ever for them to make greener choices in their daily lives.

"Our thanks to local communities for their support as we carried out this vital work in the transition towards net zero carbon emissions and a cleaner and greener future."

The work in Ayrshire aligns with SP Energy Networks' commitment to ensuring energy security for the UK, supporting job creation, the supply chain, and the broader economy.
