EAST KALIMANTAN ELECTRICITY SUPPLY PLAN

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

Electricity Condition

Electricity system of East Kalimantan consists of interconnection and some isolated systems. The interconnection system is connected through 150 kV transmission network and called Mahakam System. Peak utilization in 2011 reached 401.86 MW.

Total installed capacity of power plants in East Kalimantan up to 2011 was 752.64 MW consisting of Steam Power Plants 78.50 MW, Gas Power Plants 82.40 MW, Steam and Gas Power Plants 60 MW, Gas Machine Power Plants 46.04 MW, Diesel Power Plants 477.61 MW, Wind Power Plants 8 MW, and Solar Power Plants 0.09 MW. In 2011 electricity sale for East Kalimantan reached 2,277 GWh.

Energy Potentials

East Kalimantan has diversified primary energy potentials namely oil, natural gas, coal, hydro, thermal, and coal bed methane. Oil potentials are estimated to reach 670 MMSTB, natural gas 19.76 TSCF, and coal 49,526.90 million tonnes. Hydro potentialas are estimated to reach 168 MW namely in Kelai. Thermal potentials are estimated to reach 30 Mwe, scattered in 4 locations namely Sebakis Nunukan, Sajau Bulungan, Semolon Malinau, and Mengkausar Malinau. In addition, there are also estimated Coal Bed Methane potentials for 106.3 TCF.

Electricity Demand Estimate   

        It is projected that demand for electricity in East Kalimantan for the period 2012-2031 shall grow averagely by 15.9% per year so that in 2031 electricity need is expected to reach 42.8 TWh. To fulfill peak utilization growth of averagely around 15.6% per year until 2031, then additional power of averagely around 555 MW per year shall be needed.
