A 200-room Premier Inn in Edinburgh claims to be the first hotel in the United Kingdom to install a 100-kilowatt lithium ion battery.
It expects the new system to save £20,000 ($25,000) in energy costs every year.
The 3m3 lithium ion battery will be capable of powering the whole building, including the restaurant, for up to three hours at a time after a two-hour charge.
Premier Inn’s parent company Whitbread said the trial of the battery storage technology will help its commitment to halve its carbon emissions by 2025.
Electricity company E.ON has supplied and installed the technology at the hotel.
The hotel chain follows other companies including B&Q, a British multinational DIY and home improvement retailing company, and Veolia, an environmental service firm, which both installed lithium ion battery power systems in 2018.
