Generation

The actual capacity of CEM’s generation consists of three power stations located respectively in the Macau City namely Macau Power Station (CMC) and two on the Coloane Island namely Coloane A Power Station (CCA) and Coloane B Power Station (CCB). Together, CEM has a total installed capacity of 472 MW.

The predominant type of generation technology deployed are the low speed diesel generator (CCA) and the combined cycle gas turbine (CCB). In fact, these 2 kinds of generating units make up of 58% and 29% of total capacity installed and generated as much as 99.9% and 0.1% of total electricity production in 2013 respectively.

In 2013, the gross energy demand was 4409 GWh of which 222 GWh was produced by CEM and 4187 GWh has acquired from external suppliers. The energy breakdowns between CEM production and energy acquisition were respectively 5% and 95%. And the annual growth rate was 1.5%. The maximum values registered for energy and daily load demands were respectively 16.1 GWh and 765.6 MW.
