We have continued to invest in our gas supply network ensuring that capacity keeps pace with growing demand. Our supply network has grown over the years, currently extending to over 3,500 km serving more than 1.8 million customers throughout Hong Kong.
Grid Control Centre
Gas supply pressure must be carefully monitored and controlled at all times. To this end, we have operated a 24 x 7 grid control centre, equipped with a sophisticated Supervisory Control and Data Acquisition system (SCADA), since the early 1980s. With precision instruments installed at strategic locations throughout our network, the system continuously monitors the status of our entire supply network, raising an alarm if any abnormality is located. This greatly enhances our operation efficiencies and allows us to effectively provide a safe and reliable gas supply to our customers.
Geographic Information System (GIS)
A state of the art Geographic Information System (GIS) provides detailed computerised drawings of all our pipelines with every item of necessary information such as location, depth, materials, diameter, pressure ratings, etc. of the network being readily available. With the ready accessibility of this information and its sophisticated analysis functions, GIS not only enhances our daily operational efficiencies, it also improves our network planning. Working in conjunction with the SCADA system, GIS provides an indispensable tool in the management of our network, enabling the handling of any gas emergencies much more swiftly and effectively.
