Comparison of Existing and Newly Proposed Electricity Tariff and Rebate Schemes in Hong Kong MUI KW*, Wong LT, Cheung CT, Satheesan Manoj Kumar


Potential future cooling energy savings can be achieved through the use of incentives. This study proposes a new electricity tariff and rebate scheme to enhance the existing scheme in Hong Kong and encourage cooling energy savings during the summer months. In the study, the per–area cooling energy consumption for the public housing sector during the summer months (May to October) is benchmarked using a 5–star rating system to the determine its incentive level on the proposed tariff list. Under the proposed scheme, 5–star households will get a higher rebate rate while those with a star only will not receive any rebate. For the same amount of energy reduced, the application example demonstrates that the proposed scheme can save money as much as two times more than the existing scheme.
