SOUTH SULAWESI ELECTRICITY SUPPLY PLAN

          For those who are engaged in developing of power plants, I would like to share the following points with regard to the above subject. Warm regards.

Electricity Condition

Demand for electricity in South Sulawesi is supplied by interconnection and some isolated systems. The interconnection system is connected through 150 kV transmission network and called South Sulawesi System. The isolated systems consist of Malili-Inco and Selayar Systems. Peak utilization in 2011 reached 583.08 MW.

Total installed capacity of power plants in South Sulawesi up to 2011 was 1,120.34 MW consisting of Steam Power Plants 215.50 MW, Gas Power Plants 182.72 MW, Steam and Gas Power Plants 135 MW. Diesel Power Plants 419.91 MW, Hydro Power Plants 156.62 MW, Mini Hydro Power Plants 10.10 MW, Micro Hydro Power Plants 0.29 MW, and Wind Power Plants 0.20 MW. In 2011 total electricity sale for South Sulawesi reached 3,246 GWh.

  

Energy Potentials

South Sulawesi has diversified primary energy potentials namely coal, hydro, and thermal. Coal potentials are estimated to reach 231.24 million tonnes. Hydro potentials are estimated to reach 1,567.8 MW, scattered in 7 locations namely Masuni, Mong, Lasolo-4, Poko, Malea, Batu, and Bonto Batu. Thermal potentials are estimated to reach 463 Mwe, scattered in 14 locations namely Limbong, Parara, Pincara, Bituang, Sangalla, Watansoppeng, Sulili, Malawa, Baru, Watampone, Todong, Kampala, Massepe, and Sengkang.

Electricity Demand Estimate   

         It is projected that demand for electricity in South Sulawesi for the period 2012-2031 shall grow averagely by 11.9% per year so that in 2031 electricity need is expected to reach 29.6 TWh. To fulfill peak utilization growth of averagely 11.6% per year until 2031, then additional power of averagely 410 MW per year shall be needed.
