B&Q DC to install batteries to store solar power
02 August 2018
The Swindon distribution centre already has 552 rooftop solar panels but a lot of energy has been exported to the grid when on-site demand is low.
Kingfisher’s Swindon distribution centre uses 3.5MW of power per year on average. Currently, around 35% of the power generated by the solar panels at the site is exported back to the grid as surplus.
The energy storage batteries will mean that this energy can be stored and released back to the building to provide power during periods of peak pricing. The timed release of energy can also support its overnight operations, when the solar panels are dormant. The batteries will reduce the site’s grid power consumption by 31%, with some days where zero grid energy will be used to power the site.
These installations form a key part of Kingfisher’s aim to reduce grid energy consumption across its UK property portfolio.
Solarcentury, Kingfisher’s renewable energy partner, will manage the installation with batteries supplied by Samsung.
Each battery rack is the size of a large domestic fridge-freezer. Each one has a capacity of 94.5KW, with the total planned capacity equating to 756KW. The batteries will be able to store 40% of the power generated by the solar roof panels. The system will also power electric car charging points in the car park. Solarcentury will project manage the installation, and its ongoing maintenance and monitoring systems. The project is expected to be completed in early September 2018.
The system will complement an existing biomass boiler and chipper which will provide renewable heat for the site.
Kingfisher already purchases 100% of its UK electricity from renewable sources.
The installation is the latest milestone in Kingfisher’s strategic roadmap for sustainable growth to 2025 and moves the company towards its goal of becoming a net positive business by 2050.
