Lowering GHG emissions

We are committed to using all resources, including fuel, water and other natural resources efficiently and conservatively, and to increase the use of renewable resources.

Fuel Use

In 2017, the total fossil fuel consumption for power generation increased compared to 2016, with the use of 4.0% more coal and 5.3% more gas. For coal consumption, this was due mainly to increased output from Jhajjar in India and Fangchenggang in Mainland China, outweighing the reduction in output from Yallourn and Mount Piper in Australia, and Castle Peak in Hong Kong. For gas consumption, the increase was due to more generation from Tallawarra in Australia and Black Point in Hong Kong.

In 2017, our Group’s carbon intensity decreased to 0.80kg CO2/kWh from the 2016 level of 0.82kg CO2/kWh. It was mainly due to decreased output from the coal-fired plants of Castle Peak power station in Hong Kong, Mount Piper and Yallourn power stations in Australia; and increased output from the gas-powered and more fuel-efficient Tallawarra Power Station in Australia. The significant decrease in generation from less efficient coal plants and increase in output from a more efficient gas one in Australia meant less carbon emissions were emitted per unit of electricity sent. This reduction in carbon emissions is a trend we expect to build upon with the addition of our investment in the Yangjiang nuclear power station.

The carbon intensity of the electricity used by our customers in Hong Kong in 2017 was 0.51 kg CO2e/kWh, a decrease from 2016 (i.e. 0.54 kg CO2e/ kWh). This was a result of reduced coal consumption and maintaining the increased consumption of natural gas to meet the Government’s emissions requirements in Hong Kong, plus increased output from Guangdong Daya Bay Nuclear Power Station (GNPS) in Mainland China.
