Operation and maintenance strategies of a coal-fired Power Station in Hong Kong

The prosperity of Hong Kong highly relies on devoted people from various industries, and power industry is one of them to keep the city prosper. To ensure power supply of high quality, three aspects are what we concern most, “Reliable and safe supply of electricity”, “Environmental Care” and “Reasonable tariff”. They are the three vital targets for that we carried out myriads of actions and strategies to achieve over the years. However, the three aspects are not easy to fulfill simultaneously as we hope. Whenever we hope to maximize the performance of either “Reliability and Safety”, “Environment” and “Tariff”, there is always trade-off in other two aspects due to the limit of resource and their fundamental natures. For example, installation and upgrade of machines to enhance the emission of power generation improves the performance in terms of environment but, in the meantime, it necessarily increases the tariff due to the increased cost and affects the reliability and safety of electricity supply due to the threat posed by additional operation and maintenance activities.
