BENGKULU ELECTRICITY SUPPLY PLAN

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

Electricity Condition

Electricity system of Bengkulu together with Jambi 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 Muko-Muko, Manna, and Kaur. In 2011 peak utilization in Bengkulu System was 122.82 MW.

Total installed capacity of power plants in Bengkulu up to 2011 was 273.08 MW consisting of Diesel Power Plants 37.04 MW and Hydro Power Plants 236.04 MW. Total electricity sale in Bengkulu in 2011 was 494 GWh.

 

Energy Potentials

Bengkulu has diversified energy potentials consisting of coal, thermal, hyro, and coal bed methane. Coal potentials are estimated to reach 227.32 million tonnes, thermal potentials are estimated to reach 1,362 Mwe, scattered in 5 locations namely Tambang Sawah, B Gedung Hulu Lais, Lebong Simpang, Suban Ayam, and Kepahiang/G Kaba. Hydro potentials are estimated to reach 50 MW, scaterred in 2 locations namely Padang Guci-2 and Simpang Aur. Coal bed methane potentials are estimated to reach 3.6 TCF.

 

Electricity Demand Estimate

               It is projected that demand for electricity in Bengkulu for the period 2012–2031 shall grow by 18% per year so that in 2031 electricity need is expected to reach 12.6 TWh. To fulfill estimated peak utilization growth of averagely around 17.7% per year until 2031, then additional power of averagely around 177 MW per year shall be needed.
