Sainsbury’s has entered a ten-year deal with clean technology company RLtec to provide smart grid technology in over 200 stores, expected to save 10,000 tonnes of carbon dioxide per year in the UK.
This is the first commercial deal of its kind and has been implemented after a successful trial run in three of Sainsbury’s stores in the south-east.
The technology will manage the power consumption of equipment by responding automatically to changes in the balance between supply and demand on the grid. This eliminates the constant need for carbon dioxide producing power stations that are currently held in reserve to perform the balancing service.
RLtec’s technology can also change the timing of heating and ventilation systems to match demand on the grid. Overall the system is expected to improve management of electricity supply and demand across the entire national grid and boost energy efficiency.
Sainsbury’s property director Neil Sachdev said, ‘By introducing this technology, we will cut the UK’s dependence on fossil fuels, reduce our own energy costs and reduce our carbon dioxide emissions. As a large retailer, we are able to make a tremendous difference by investing in new technology and rolling it out onto our estate.’
