A hotel in Edinburgh has become the first battery-powered Premier Inn to enable it to manage its energy consumption more positively.
The Gyle, at Edinburgh Park, is trialling the new 100kW lithium ion battery to help secure power supply and enable energy cost savings on-site.
The Whitbread-owned Premier Inn has a battery 3m3 in size which will take two hours to charge and operates by drawing power from the National Grid during off-peak periods. It has the capacity to run the 200-room hotel – including meals cooked at its Thyme bar and grill – for up to three hours.
The five tonne battery will be used for at least 2-3 hours per day on-site, depending on the needs of the National Grid.
The hotel was chosen as the first site to trial the battery in part because Scotland is a large producer of renewable power, such as wind power, and the battery will help the National Grid by reducing demand from the system.
The battery trial allows the Premier Inn site 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.
The battery technology has been supplied and installed by E.ON, who will be remotely managing the battery’s workload and efficiency from its energy management centre in Glasgow.
Premier Inn currently has more sites with solar panels than any other hotel chain in the UK, with a total of 169 to date.
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”.
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.”
If successful, the trial could be extended more widely across the Premier Inn estate.
