Customers of Hong Kong’s CLP Power are set to pay higher power bills next month, as the company increases its fuel costs for a third consecutive month to 42.6 HK cents (5.4 US cents) per unit of electricity, up 5.4 per cent from May.CLP Power, which serves over 80 per cent of Hong Kong’s population, announced its fuel cost for June at 42.6 HK cents per kilowatt-hour (kWh) on Tuesday, up from 40.4 HK cents in May.CLP’s monthly fuel cost has been rising steadily since March. The charge for June marked an 8.7 per cent increase from 39.2 HK cents per unit of electricity in March.According to CLP’s bill calculator, a typical three-member family, which consumes 275 kWh of electricity monthly, is estimated to pay HK$380.09 for its power supply this month.The adjustment came after HK Electric, the city’s other utility firm that mainly serves Hong Kong Island and Lamma Island, increased its June fuel cost to 31.3 HK cents per unit of electricity.CLP Power’s net tariff – the total price paid by consumers – is generally calculated by combining the basic tariff and the fuel cost adjustment, which includes both monthly and annual figures.
