JAMBI ELECTRICITY SUPPLY PLAN

For those who are interested in developing power plants in Jambi, I would like to share the following points with regard to the above subject. Hopefully they woud be of use.

Electricity Condition

Electricity system of Jambi together with Bengkulu and South Sumatera has been interconnected through 150 kV transmission network called South Sumatera, Jambi, and Bengkulu (S2JB) system. Almost all of electricity need (96%) of S2JB is supplied by Sumatera Power Distribution and Transmission Center (SPDTC) through 150 kV transmission network in Southern Sumatera Interconnection System (SSIS) and the rest is supplied by isolated system power plants in Muara Sabak, Tanjung Jabung Timur, and Sarolangun. In 2011 peak utilization in Jambi System was 235.94 MW.

Total installed capacity of power plants in Jambi up to 2011 was 273.61 MW consisting of Steam Power Plants 6 MW, Gas Power Plants 164.97 MW, Gas Machine Power Plants 36.50 MW, Diesel Power Plants 65.92 MW, and Micro Hydro Power Plants 0.22 MW. Total electricity sale of Jambi in 2011 was 1,054 GWh.

Energy Potentials

Jambi has diversified energy potentials consisting of coal, thermal, and hydro. Coal potentials are estimated to reach 2,341.97 million tonnes. Thermal potentials are estimated to reach 1,032 MWe scattered in 8 locations namely G Kapur Kerinci, G Kaca Kerinci, Sungai Betung, Semurup, Lempur, Air Dikit, Graho Nyabu, and Sungai Tenang. Hydro potentials are estimated to reach 373.9 MW scattered in 2 locations namely Merangin-2 and Merangin-5.

Electricity Demand Estimate

 

It is projected that demand for electricity in Jambi for the period 2012–2031 shall grow by 20% per year so that in 2031 electricity need is expected to reach 35.5 TWh. To fulfill estimated peak utilization growth of averagely around 19.6% per year until 2031, then additional power of averagely around 490 MW per year shall be needed.
