Customers of Hong Kong’s CLP Power are facing higher electricity bills in June, with the company increasing its fuel cost charge by 5.4 per cent from May, its third consecutive monthly rise.

CLP Power, which serves more than 80 per cent of Hong Kong’s population, announced on Tuesday that its fuel cost adjustment for June would rise to 42.6 HK cents (5.4 US cents) per kilowatt-hour (kWh), up from 40.4 cents in May.

CLP’s monthly fuel cost charge has been rising steadily since March. The charge for June marks an 8.7 per cent increase from 39.2 cents per unit of electricity in March.

According to CLP’s bill calculator, a typical three-member family consuming 275 kWh of electricity monthly is estimated to pay HK$380.09 for its power supply this month.

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.

The monthly fuel cost adjustment is calculated based on a comparison between the actual average fuel price over the three preceding months and the fuel price projection.
