While the accommodation sector still represents a relatively small percentage of the UK’s total energy demand, it is also one of the fastest-growing proportions. Since 1990, the total energy consumption of the hotel sector in the UK has doubled, and now makes up around 1% of total demand. Energy efficiency in that period has improved significantly, with the typical hotel now using 20% less energy per bed. Despite these improvements, energy costs now represent a growing proportion of the hotel’s overall overheads. Alongside pubs and restaurants, hotels were one of the sectors hardest hit by the energy crisis, driving hundreds out of business.

Energy challenges faced by hotels

Hotels face complex energy management challenges, with a need to consistently meet the expectations of guests with reliable power, with a competitive industry making them reluctant to pass costs on to those guests directly. Alongside 24-hour use of lighting and electrics in rooms, hotel energy costs are often increased by swimming pools, gyms, spas and restaurants. A growing number of guests look for hotels that can provide EV charging facilities overnight, with rapid EV charging representing a significant increase in energy consumption as well as demand on grid connection.

Consumers increasingly take sustainability factors into their purchasing decisions, and their choice of hotels further reflects that. Tourism awards are a key part of raising the profile of many hotels, particularly high-end destinations, and sustainability efforts are a growing factor considered by awards bodies. Bolstering carbon reduction efforts, and effectively communicating those improvements to key audiences, is vital.

Technologies that can help hotels

As well as keeping energy costs down, ensuring that guests enjoy a stay unaffected by power disruption is important for hotels. A battery energy storage system is a good way of achieving this, as well as addressing other energy management priorities at the same time. In the event of power disruption, a battery energy storage system can keep a site operational and ensure that the experience of guests isn’t impacted. It can also be used to buffer the growing number of rapid EV chargers used by hotels, rather than placing additional strain on their grid connection. With many hotels having already invested in on-site generation such as solar panels, a battery can maximise their efficient by storing power generated during periods of sunny weather and allowing it to be used at other times when generation is lower, such as overnight.

Voltage optimisation works by lowering and conditioning incoming voltages, with the average UK site being supplied with an overvoltage from the grid. This can significantly improve energy efficiency and reduce energy costs, while also reducing wear and tear on equipment and infrastructure and subsequent maintenance costs.
