Hong Kong families with rooftop solar panels or wind turbines could sell energy for up to five times the current electricity price
The Environment Bureau says the higher rate is necessary to incentivise independent producers but assures consumers they won’t see a spike in electricity bills for now
Hong Kong households and businesses that produce renewable energy through rooftop solar installations or wind systems could soon sell their excess supply to the city’s power grid – and charge up to five times the current retail price.
An Environment Bureau proposal submitted to the Legislative Council environmental affairs panel on Monday said the payment to independent producers – known as the feed-in tariff – would be set at HK$3 (US$0.38) to HK$5 per kilowatt-hour (kWh) of electricity to spur investment in clean energy production.
Time for Hong Kong’s power companies to lead the energy revolution for a sustainable city
The city’s two power companies, CLP Power and HK Electric, charge consumers about HK$1.12 to HK$1.15 per kWh.
The bureau said it had worked with an external consultant to study the appropriate feed-in tariff rates for renewable energy systems that could generate different amounts of energy to help recover the cost of their investments quicker.
“[The rates were set] with a view to enabling … owners to recover the cost of the system as well as installation, operation and maintenance costs in around 10 years,” it said.
The clean energy produced will be sold to both power companies – CLP Power, which supplies electricity to Kowloon, the New Territories and Lantau; and HK Electric, which covers Hong Kong Island.
