Damaged plant disrupts electricity in Jakarta, Tangerang

Publication Date : 13-05-2014


Some parts of Jakarta and Tangerang experienced rolling blackouts Monday following problems at the gas-fired Muara Karang power plant in North Jakarta.

“Jakarta and Tangerang are suffering a deficit of some 600 megawatts [MW] due to the problems in Muara Karang power plant’s Kembangan sub-system and Muara Karang-Gandul transmission system,” state-owned electricity company PT PLN communications and environment deputy manager, Roxy Swagerino, said in a release made available to The Jakarta Post on Monday.

He said the affected areas were Grogol; Budi Kemuliaan; Kebon Sirih; Semanggi; Kebayoran Lama; Kebon Jeruk; MH Thamrin; Hayam Wuruk; Tanah Abang; Bintaro; Daan Mogot; BSD City; and Lippo Karawaci.

In addition, the problem also disrupted Jakarta’s Duri-Tangerang commuter-line services.

Meanwhile, the blackout also created chaos in Jakarta as traffic lights went out in a number of locations.

“The traffic light problem caused gridlock between Pos Pengumben and Joglo,” said Jakarta Police’s Traffic Management Center on its Twitter account at 4:46 p.m. on Monday.

Congestion also occurred on the Antasari flyover heading to TB Simatupang.

PLN senior manager for corporate communication Bambang Dwiyanto said the disruption was due to system failure and not a transformer malfunction.

“We are investigating the cause of the disruption. Recovery measures and electricity maneuvers have been taken. We expect everything to be normal tonight so that we won’t see any scheduled blackout,” Bambang said Monday.

The Muara Karang plant is the backbone of electricity supply to Jakarta with 1,500 MW in capacity. Jakarta’s electricity peaks at 5,500 MW, which is supplemented by a 1,000 MW power plant in Tanjung Priok and other high voltage networks connected to the Java-Bali system, according to Bambang.

Disruption in Muara Karang occurred at the same time as disruption at Pacitan power plant in East Java, according to Bambang.

Disruption in Pacitan occurred prior to Muara Karang, at around 3:30 p.m. “We’re still investigating whether the two are related,” he said.
