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 for its coal-fired power generating units. In 2017, the Group completed the ultra-low-emission technical upgrade works of six coal-fired power generating units in total. As of 31 December 2017, the Group had completed the ultra-low-emission technical upgrades of all nineteen coal-fired power generating units.
In 2017, the operational ratio of desulphurization facilities for the coal-fired power generating units of the Group was 100% (2016: 100%), and the efficiency ratio of desulphurization was 98.42% (2016: 96.67%); the operational ratio of denitration facilities reached 100% (2016: 99.92%) and the efficiency ratio of denitration reached 92.98% (2016: 84.14%).
During the year under review, the environmental protection indicators for coal-fired power generating units were further improved:
the emission rate of sulphur dioxide (SO2) at 0.063g/kWh, representing a decrease of 0.087g/kWh as compared with the previous year;
the emission rate of nitrogen oxide (NOx) at 0.095g/kWh, representing a decrease of 0.090g/kWh as compared with the previous year; and
the emission rate of flue gas and dusts at 0.013g/kWh, representing a decrease of 0.022g/kWh as compared with the previous year.
To prevent pollutants from exceeding the emission standards at source, the Group has also incorporated concepts and requirements of social responsibilities in the management of suppliers, and clearly stipulates that the materials must meet the standards of 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 labor tools and labor protection gears that are compliant with safety standards, while a variety of safety knowledge, safety skills training, as well as emergency training and drills 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 the Prevention of Occupational Diseases and other laws and regulations relating to safety and hygiene.
In order to further enhance its core competitiveness and promote sustainable development, the Group has established the accredited QHSE "three standards" management system that complies with the international standards, which plays an important role for the Company to pioneer the innovative management model, enhance the management quality and promote transformational development.
In 2017, no material 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 safety production regulations of China. No fines or charges were imposed due to violation of regulations.
