NORTH SULAWESI 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 

Demand for electricity in North Sulawesi is supplied by interconnection and some isolated systems. The interconnection system is connected through 150 kV transmission network and called Minahasa System. The isolated systems consist of Tahuna, Melonguane, Ondong-Siau, Tagulandang, Beo-Talaud, Lirung, and Molibagu Systems. Peak utilization in 2011 reached 206.39 MW.

Total installed capacity of power plants in North Sulawesi up to 2011 was 342.36 MW consisting Diesel Power Plants 202.56 MW, Hydro Power Plants 51.38 MW, Mini Hydro Power Plants 8 MW, Thermal Power Plants 80 MW, Wind Power Plants 0.08 MW, and Solar Power Plants 0.34 MW. Total electricity sale for North Sulawesi in 2011 reached 987 GWh.

Energy Potentials

North Sulawesi has thermal and hydro primary energy potentials. Thermal potentials are estimated to reach 793 Mwe, scattered in 5 locations namely Air Madidi, Lahendong, Tompaso, Gunung Ambang, and Kotamobagu. Hydro potentials are estimated to reach 16 MW namely in Sawangan.

Electricity Demand Estimate   

          It is projected that demand for electricity for the period 2012-2031 shall grow averagely by 15.1% per year so that in 2031 electricity need is expected to reach 15.6 TWh. To fulfill peak utilization growth of averagely around 14.8% per year until 2031, then additional power of averagely around 219 MW per year shall be needed.
