tate electricity firm PLN said Tuesday that the power system on Java was back to normal after a massive blackout hit Greater Jakarta, West Java and Banten on Sunday for more than eight hours.
The system started to operate normally on Monday at 5:50 p.m. in Jakarta, at 9:20 p.m. in Banten and 11:27 PM in West Java.
"Alhamdullilah [praise God] the whole system is back to normal and we will ensure its stability," PLN acting president director Sripeni Inten Cahyani said in a statement.
The firm stated that 12.3 gigawatts (GW) of power had been restored with 23 high voltage substations active. The peak load in the affected areas was recorded at 13.6 GW on Tuesday, while the system's capacity stands at 15.3 GW.
PLN also said 15 power plants, which supply the Java-Bali power system, had been operating since Tuesday morning, most of which were coal-fired power plants (PLTU).
"There are three other PLTU that will come into the system tonight, namely PLTU Pelabuhan Ratu 1, PLTU Pelabuhan Ratu 3 and PLTU Suralaya 1," Sripeni said.
She further gave assurances that the 500-kilovolt (kV) transmission line, which was disrupted on Sunday that led to the blackouts, and the 150 kV line were back to normal.
At the same time, the firm reiterated its commitment to compensate the affected customers, which were estimated at 21.3 million people. It said the compensation would be given to all customers segments, including prepaid ones.
