At the Group’s Royal National, Tavistock, Imperial and President Hotels they provide nearly 3,000 guest rooms for visitors to the Capital. Heat and hot water is supplied by combined heat and power units. Being in close proximity to one another, the four hotels are served by two plant rooms, with two plant rooms on standby to act as backup during scheduled maintenance periods. The Royal National and Tavistock hotels share one 122kWe and one 225kWe unit. The Imperial and President Hotels share two 122kWe units.
Rather than purchase the systems outright, they chose to use ENER-G’s Discount Energy Purchase agreement. Under this arrangement, they agreed to buy energy at discounted rates, thereby making immediate savings. It is estimated that the systems will save the group over £40,000 per annum. The average carbon savings are approximately 800 tonnes of CO2 per annum.
