About this member
Private utility company, the exclusive concessionnaire to generate, transmit, distribute, sell, import and export of electricity in Macau.
The predominant type of generation technology deployed is the low speed diesel generator. In fact, this kind of generating units make up of 49% of total capacity installed and generate as much as 91% of total electricity production in 2007. The Technology used in CCB is Combined Cycle (each combined cycle has two gas turbines and one steam turbine), which is substantially less polluting than the technology of generators that equipped the CCA. This represents a very important advance in the field of environmental protection. The construction of a sludge incinerator is another realization of technology being used in pursuit of environmental protection.
The installation of Selective Catalytic Reduction system in all the Diesel generators of lower voltage installed in CCA, has been seen as another significant step in reducing environmental impact. The installation of this system permits a substantial reduction of nitrogen oxides and particulates emitted, to levels well below the limits imposed to similar technologies and combustibles.
Improved and expanded services of the company, along with environmental development have been the major pillars of a vision of the company centered on customers. The company looks for every way to satisfy the needs of its customers and render excellent service quality, while at the same time being an active partner in the contribution for the success of the policies of the MSAR Government.
