Onyx Ta-Ho Environmental Services Co. has been entrusted from June 1995 to October 2007 by Taiwan Cement Corporation to operate and maintain the power generation and power supply for its HuaLien Cement Plant. The scope of service as follows:
69 kv/6.9 kv main substation
7,330 kw waste heat recovery system
3 heavy oil/diesel engine generators (3 x 6,330 kw)

As an alternative, TCC use the waste heat from flue gas emitted by cement kiln and clinker cooler to produce steam that serves as power source for a steam turbine generator. The power generated by this steam turbine generator covers for more or less one third of power demand of HuaLien Cement Plant.

In addition, 3 heavy oil/diesel generators complete the power generation system of the cement plant.

This stable power supply provided by HuaLien Cogeneration Plant has been enabling TCC to reduce its power cost still producing regular cement.
