Secretary General of Indonesian Coal Society Indonesia

The Indonesian situation has arisen from the imbalance of electric power demand growth and the development of its supply capacity. With the difficult condition of investment as today, it is difficult to implement network expansion and power plant construction. The advantages of developing small scale power plant are: relatively more competitive compared to Diesel Plant, can be used to provide electricity to coal mining process or steam that may be required for drying of coal to get lower moisture content, and requires relatively low financing capability to install, requires 20 kV lines to distribute its generated electricity hence it could assist the Government/PLN to provide electricity especially in the city nearby the mining complex, and relatively easier and faster to install. The coal fired Steam Power Plant (2 X 7 MW) consist of 2 (two) complete Stoker Boiler, capable of burning and fired with a wide range of coal without any problem in achieving the plant efficiency as well as environmental requirement. The efficiency of the boiler is 84 % and overall efficiency is 21 %. The Project have selected 80 % as the capacity factor for the purposes of the Feasibility Study after a concentrated effort to balance a low tariff rate, efficiency, project viability, increased local funding and risk sharing. The proposed Tariff Rates would b
