Potential connectivity for better security
• Linking with HEC due to SCL• Better assurance on the supply security
due to two sources of supply
Opening of electricity market will have impacts on
• Price structure• Security • Reliability• Choice of optimal supplier
Opinion
Being a mass transit service provider and probably one of the largest electricity consumer in HK, KCRC is closely observing the development of the electricity market reform with an open-minded.
Bottom Lines
To obtain electricity power withGood security
High reliability
Best price
for enabling KCRC to provide good service to passenger
