Power blackouts in Jakarta, because there are bottlenecks in the IBT 500/150 kV electric transmission in Jakarta

PT Perusahaan Listrik Negara (Persero) considered that the electricity supply in Jakarta is not constrained by energy sources in the region. In the event of a power cut, it is caused by congestion due to damage electrical relay and Master Cawang Kembangan, because there are bottlenecks on the 500/150 kV IBT Main Relay Cawang after burning, "said Deputy Director of Engineering PLN Doddy Hertanto in Jakarta.He explained, due to damage two of the seven main guardhouse, Jakarta experienced a deficit of electricity supply to 800 megawatts.
The deficit occurred because interbus transformer (IBT) in the capital city could not meet the required electrical load. Almost all IBT got loads more than 80 percent, and some even have full 100 percent. This damage berpontensi IBT itself. "In October 2009, in Jakarta peak load reached 17,000 megawatts. No problem with IBT from 500 kV to 150 kV because IBT is broken,"

To overcome this, he said, PLN will speed up resolution of the main relay station improvements expected to be completed MH and on December 19, 2009. PLN will also increase the number of IBT 500/150 kV 500 MVA at each bus shelter is the parent of the parent and to build 500 kV bus shelter at the Muara Tawar and Duri Kosambi which will be completed until 2013.

To meet the electricity needs in Jakarta, there needs to be 500 kV transmission network in the north (Muara Tawar-Muara Karang-Suralaya). However, it needs participation from the community. "Because of land acquisition costs would be enormous," Doddy said.

Department faculty Faculty of Electrical Engineering, University of Indonesia, Iwa Garniwa, say, the primary source of electrical energy in Indonesia actually very abundant. Electricity supply and the load was still in a balanced condition, although still lacking electricity reserves. The government kedala been unable to realize the power development plan in a timely fashion. This can be seen from thes project schedule generating 10,000 megawatts of electricity.
