In positive response to the policy of "Action Plan of the Upgrade and Renovation for Coal-fired Units to Achieve Energy Saving and Emission Reduction (2014–2020) (煤電節能減排升級與改造行動計劃(2014–2020年))" issued by the PRC government, the Group continued to strengthen the environmental protection measures to its coal-fired power generating units. For the year ended 31 December 2016, the Group had thirteen coal-fired power generating units completed the ultra-low-emission improvement works. For the remaining coal-fired power generating units, we will also speed up the implementation of ultra-low-emission projects.
In 2016, the operational ratio of desulphurization facilities for the coal-fired power generating units of the Group was 100% (2015: 100%), and the efficiency ratio of desulphurization was 96.67% (2015: 96.23%); the operational ratio of denitration facilities reached 99.92% (2015: 99.70%) and the efficiency ratio of denitration reached 84.14% (2015: 80.10%).
During the year under review, environmental protection indicators for coal-fired power generating units were further improved:
the emission rate of sulphur dioxide (SO2) at 0.150g/KWh, representing a decrease of 0.048g/KWh compared with the previous year;
the emission rate of nitrogen oxide (NOx) at 0.185g/KWh, representing a decrease of 0.027g/KWh compared with the previous year; and
the emission rate of dusts at 0.035g/KWh, representing a decrease of 0.015g/KWh compared with the previous year.
To prevent pollutants from exceeding the emission standards, the Group also incorporates concepts and requirements of social responsibility in the management of suppliers, clearly stipulates that the materials must meet the relevant national environmental protection laws while signing material purchase contracts.
During the year under review, all the power plants in which the Group has operational control, complied with the relevant environmental protection regulations of China. No fines or charges were imposed due to violation of regulations.
The Group's employees are equipped with labour tools and labour protection gears that are compliant with safety standards, while a variety of emergency training and exercises have been arranged, as the Group continues to improve its conditions for operations in strict compliance with the Laws of The People's Republic of China on the Safety Production and the Laws of The People's Republic of China on and the Prevention of Occupational Diseases and other laws and regulations relating to safety and hygiene. In addition, the Group has clearly specified the requirements of the index when making contracts with the coal suppliers, ensuring the safety of transportation and storage.
In 2016, no material safety accident in the aspects of employees, facilities and environmental protection occurred in the Group.
During the year under review, all operating power plants in which the Group has operational control, complied with the relevant production safety regulations of China. No fines or charges were imposed due to violation of regulations.
