The UK’s first battery-powered hotel is now operational in Scotland.

The Gyle Premier Inn in Edinburgh is trialling a new 100kW lithium-ion battery supplied and installed by E.ON at its 200-room site in a bid to improve energy efficiency, secure power supply and enable onsite energy cost savings.

The battery is 3m3 in size and weighs approximately five tonnes. It can run the hotel – including powering meals cooked at its restaurant – for up to three hours. The battery takes two hours to fully charge and will be used for at least two-to-three hours per day, depending on the needs of the National Grid.Premier Inn unveils UK’s first battery powered hotel

As well as powering the hotel, the trial of the new battery storage system allows the Premier Inn to avoid increased peak-time energy costs and generate revenue by offering energy support services to the National Grid. The installation is expected to save the hotel £20,000 per year in energy savings alone.

E.ON will remotely manage the battery’s workload and efficiency from its energy management centre in Glasgow.

The hotel is owned by Whitbread, which plans to cut its carbon emissions in half by 2025 and has already installed solar panels at 169 of its UK sites.  

Cian Hatton, Whitbread’s Head of Energy and Environment, said it was “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”.

Richard Oakley of E.ON added: “The Gyle 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.”
