A Scottish hotel has become the first in the UK to be powered by battery.
The Gyle Premier Inn in Edinburgh has installed a five-tonne battery which will charge up from the national grid during cheaper-rate off-peak periods and power the 200-room venue for several hours each day.
The technology is expected to cut the hotel's energy bill by £20,000 a year, as well as reducing its environmental footprint.
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.
Cian Hatton, Whitbread's head of energy and environment, said: "Batteries are of course everyday items, more commonly associated with powering small household goods like the TV remote control, so it's incredibly exciting to launch the UK's first battery-powered hotel – an innovation which will save money, ensure security of supply and support the transition to a more flexible grid."
The hotel chain follows other companies including B&Q and Veolia, which both installed lithium ion battery power systems in 2018.
Electricity company E.ON has supplied and installed the technology at the hotel and will remotely control the battery's workload and efficiency from its energy management centre in Glasgow.
Richard Oakley, customer accounts director at E.ON, said: "The Gyle at Edinburgh Park is already an energy efficient hotel thanks to the remote monitoring and management of its systems from our control centre in Glasgow.

"By adding the flexibility of battery storage we can also help Whitbread to upgrade to the full-board option of drawing electricity from the grid when prices are low, storing that energy for use at peak times and having the ability to sell it back to the grid to help balance supply and demand on the network.
"Premier Inn is showing how hotel chains and large power users can further save money, reduce their carbon footprint and support the development of a lower-carbon, smarter energy grid in the UK."
