The annual electricity expenditure of hotels operating in this mode depends on the scale, facilities, operation and many other factors of the hotel.

Suppose a hotel chain has 10 branches, and each branch consumes 500,000-3 million kWh of electricity every year. Then the total electricity consumption of the whole hotel chain is about 5-30 million kWh a year.

According to the information that the electricity charge is usually the biggest expenditure of the hotel except the site cost and labor cost, it can be estimated that the electricity charge of chain hotels accounts for about 20%-30% of the whole operating cost. Therefore, the electricity expenditure of the whole hotel chain is about 6.5438+0 million-9 million.
