Last update date: 2020-05-06 12:32"Hong Kong Climate Action Blueprint 2030+" plans to gradually reduce coal-fired power generation, and this year natural gas will meet about half of Hong Kong's electricity supply. The Secretary for the Environment, Huang Jinxing, responded to a question from Members today (6th) that the two power plants each put into operation a new gas-fired generating unit this year, and the proportion of natural gas power generation will increase to about 50%, in line with the "Blueprint" expectations.
As for the offshore wind power generation in Hong Kong, the two power assessments require more than 10 billion yuan, and the power generation capacity is only about 300 megawatts, accounting for less than 1.5% of Hong Kong's total power consumption. The cost is higher than natural gas power generation.

In a written reply, Huang Jinxing stated that power generation and gas production had the highest greenhouse gas emissions in 2017, reaching 26,600 thousand metric tons of carbon dioxide equivalent, accounting for about 65% of the total emissions; last year, coal-fired power generation still accounted for about 44% of Hong Kong ’s overall power generation fuel mix. Natural gas power generation accounts for about 29%, and about 27% is imported from the mainland for nuclear power and local renewable energy.
He also pointed out that each of the two power companies will have a new gas generating unit put into operation this year, the percentage of natural gas power generation in Hong Kong will increase to about 50%, and coal-fired power generation will be reduced to about 25%, which is in line with the expectations of the Hong Kong Climate Action Blueprint 2030+ ; In the next 10 years, the two power companies will continue to replace the retired coal-fired generating units with gas-fired generating units and non-fossil energy sources.

The cost of developing offshore wind farms in Hong Kong is high
Asked about the feasibility and economic benefits of developing offshore wind farms in Hong Kong, Huang Jinxing said that according to the assessment of the power company, Hong Kong has two domestic offshore locations (that is, the water off the Guozhou Islands and the waters near Lamma Island ) It is more suitable for the development of wind farms on a commercial scale. The two power companies have also been conducting wind measurement at the above locations, but the total capital required for the two projects exceeds 10 billion Hong Kong dollars. The total power generation capacity is about 300 megawatts. It is estimated to account for less than 1.5% of Hong Kong's total electricity consumption, and the cost is higher than that of natural gas power generation. He believes that due to various uncertainties, he will continue to pay attention to the development of the relevant parties.
In addition, some Members are concerned about the Hong Kong government's policy of promoting electric vehicles. Huang Jinxing replied that as of the end of March this year, the government fleet had a total of 224 different types of electric vehicles, mainly small and medium-sized motor vehicles, accounting for 9.2% of the total number of government motor vehicles, which is higher than the overall ratio of electric private cars in Hong Kong to 2.2% of the total number of private cars. . As for special purpose vehicles (such as garbage collection vehicles), buses, medium and heavy goods vehicles, there are still no electric vehicle models on the market that meet the operational needs of the department.
