Keywords: Waste Heat Recovery Power Generation (WHRPG), electrical power, renewable energy


The coal combustion processes which require high temperature will produce waste heat energy. The energy   can be used as generator propulsion to produce electrical energy.  Thus, Semen Padang Corporation has successfully got  funding from the Japan government, New Energy Technology Development Organization (NEDO) to build the installation Waste Heat Recovery Power Generation (WHRPG) located in the production area of Semen Padang Corporation, Indarung V. Furthermore, heat energy process can not be operated manually, so control system is needed to control this WHPRG performance. The operational of WHPRG can produce electricity power 196.15 MW  as to reduce the electric power that must be supplied by Indonesian Electricity Corporation. Besides that, the outcome of Semen Padang Corporation can be saved 33 billion Rupiah per year and CO2 emission can be declined 33,000 tons per year.
