Scottish Water has revealed plans to deploy more than 400MW of large-scale battery storage across its estate.
The company has formed a partnership with Bluestone Energy, which will install and manage the batteries.
Bluestone has submitted proposals to the Scottish government to build 207MW of battery storage at Scottish Water’s Laighpark wastewater treatment works, Stanely water treatment works and Linwood wastewater pumping station.
These first three systems will each comprise 20 battery storage units with a combined power output of 69MW and storage capacity of 69MWh, as well as a control room and infrastructure to connect to the local electricity network. The sites were chosen for proximity to SP Energy Networks substations with available connections points and grid capacity.
Donald MacBrayne, business development manager of Scottish Water’s commercial subsidiary, Scottish Water Horizons, said: “These projects align with Scottish Water’s ambitions to be net zero by 2040 and goes beyond by working in partnership with others to reduce their emissions too. By taking this approach we can all make significant contributions to Scotland’s net zero goals.”
He said the batteries will not supply power directly to the water company, but will provide a source of revenue from leasing the land that can be reinvested in renewable projects.
Following the first three projects, Bluestone Energy will add storage systems to three further Scottish Water sites, bringing the total power output across all six facilities to 403MW.
