The figure indicates progress in the utility’s objective to achieve net zero emissions by 2040, which is five years ahead of the national target in Scotland, according to The Herald.

Solar panels are generating electricity at 100 Scottish Water sites, such as treatment works, pumping stations, as well as operational buildings.

The most recent installation is near Falkirk at Kinneil Kerse Wastewater Treatment Works. 

The combined installations generate roughly 25.1 gigawatt hours of renewable electricity per year, helping to decrease dependence on the electricity grid, reduce carbon emissions and safeguard the business from energy price volatility. 

The utility’s commercial subsidiary, Scottish Water Horizons, spearheads the programme - which was established in 2011 - identifying sites where renewable energy projects can provide both environmental and operational benefits.

The installations incorporate biodiversity measures, such as wildflower meadows, bird and bat boxes, and habitat enhancements for amphibians and reptiles.

Milngavie Water Treatment Works, Newbridge Wastewater Treatment Works near Edinburgh and Longman Drive in Inverness are some examples of current installations. 

Solar projects have also been delivered on Bute, in the Borders and at locations within urban and rural Scotland.

Donald Macbrayne, business development and delivery manager at Scottish Water Horizons, said: “These schemes are helping to reduce carbon emissions, lower operational costs and make our sites more resilient. 

“They also provide long-term value for customers by reducing our exposure to volatile electricity prices.”

Gillian Martin, cabinet secretary for climate action and rural affairs, said: “Alongside work to preserve biodiversity, these projects show how climate action can support nature recovery while helping drive Scotland’s transition to net zero.”
