Jakarta. State-controlled electricity company PLN has been investigating the cause of Tuesday’s (02/01) sustained power outage in the greater Jakarta area to improve the company's mitigation system in the future, an official told the Jakarta Globe on Wednesday.
I Made Suprateka, corporate communication of PLN, said a four-hour outage in Jakarta and surrounding areas on Tuesday morning was caused by unresponsive operating systems at Gandul and Muara Karang power stations in Depok, West Java, and West Jakarta, respectively.
The outage affected 15 other power stations as well, mostly those that supply electricity to North Jakarta. During the outage, 63 power stations were still operating, Made said.
He added that the company has been calculating losses caused by the outage, but "the first thing is we try to find the cause of it to conduct risk mitigation, so it won’t happen again."
"We still need to examine the event to make corrections [for the future]," he added.
The accident has exposed a vulnerability in basic infrastructure in Indonesia’s capital.
Even though some power stations resumed normal operations, the outage disrupted the Indonesia Stock Exchange (IDX) trading system early on Tuesday.
