In addition, power supply from Gandul Extra High Voltage substations in Depok, West Java Province, will be channeled to Muara Karang gas and steam power plant (PLTGU) to supply electricity to the Indonesian capital city, Jakarta.
Acting President Director of PLN Sripeni Inten Cahyani said here on Sunday that the power supply to Jakarta was expected to recover within three hours.
"We apologize for the inconvenience today, and currently all efforts have been made to recover the Java-Bali power system, especially in the area of West Java, Banten, and Jakarta," Cahyani said.
The company has focused on power supply to PLTGU Muara Karang and PLTGU Priok to recover the system in the capital city.
Previously, PLN has recovered the operation of hydro-generated power plant (PLTA) Saguling and PLTA Cirata which are functioned as power stabilizer, and, at the same time, supply the electricity to PLTU Suralaya through Cibinong, Depok, Gandul, Lengkok, Balaraja and Suralaya extra high voltage substations.
PLTU Suralaya is expected to return to its normal operation within six hours to normalize power system in West Java and Banten.
Blackout that affected thousands of homes and public facilities in West Java, Jakarta, and Banten was caused by several troubles in the extra high voltage 500 kV transmission of Ungaran - Pemalang.
"PLN has taken its best efforts and will have evaluation to prevent recurrence of today's incident," Cahyani said.
