Electricity sector in Macau

In 2012, CEM produced 376 GWh to supply 8% of Macau's 4,344 GWh gross energy demand, while the remaining 3,968 MW (92%) was imported from Mainland China through Guangdong Power Grid under China Southern Power Grid Company.

Almost all CEM's power network is constituted by underground cables which mainly come from Europe, United States and South Korea.

These five interconnection circuits give a total of 1,750 MVA importation electric capacity for Macau from Guangdong in Mainland China.

By the end of 2007, CEM was providing electricity to 211,238 customers, in which 75% of them are in the Macau Peninsula, while the remaining 21.9% are in Taipa and 3.1% in Coloane.

CEM was the first public utility company in Macau and the first power company in Hong Kong and Macau to obtain the certification ISO 14064-1 Greenhouse Gases Management System by taking systematic and genuine actions against greenhouse gases emissions.

In order to cope with the growing concern on environmental issues, CEM has invested more than MOP 450 million to improve CEM environmental performance, including investment in Selective Catalytic Reduction Systems, Natural Gas Conversion, Air Quality Monitoring Systems, Scrap Yard, Noise Control Facilities etc.
