Scottish Water's £2.3m Solar Power and Battery Energy Storage Scheme
Scottish Water has completed work on a £2.3 million solar power and battery energy storage scheme which is set to save around 169 tonnes of carbon annually.
The scheme, at Howden Water Treatment Works near Selkirk, consists of 2,112 ground-mounted solar panels and 15 racks of batteries to store the power generated – which will meet over a third of the site’s power usage and support Scottish Water’s drive to reach net zero emissions by 2040.
The battery energy storage system, the first of its kind on a Scottish water treatment asset and only the second on a Scottish Water site to date, means 100 per cent of the renewable power generated by the scheme can be used on site whenever it is needed.
Scottish Water Horizons Project Manager Alan Mearns said: “This scheme will generate 1.2 megawatts of green electricity, providing just under 35% of the annual electricity needed to power the site and will make a massive difference to the carbon footprint of the treatment works."
