    TEMPO.CO, Jakarta - State power company PLN has reactivated 15 power plants to supply the Java-Bali grid. The power plants generate a total of 12,378 megawatts (MW) of electricity.

    In addition to the 15 power plants that began transmitting electricity Tuesday morning, PLN has also operated 23 extra-high voltage substations (GITET) and will add three additional power plants.

    "The entire system is normal and we will continue to maintain the stability of this system," PLN acting CEO Sripeni Inten Cahyani said in her official statement, Tuesday, August 6.

    Among the reactivated power plants are the Suralaya steam power plants (seven units); Salak geothermal, Saguling hydropower, and Indramayu steam power plant (two units).  The three additional ones are steam power plants Pelabuhan Ratu 1, Pelabuhan Ratu, and Suralaya 1. 

    According to Sripeni, the recovery was successfully carried out since Monday, August 5, at 17.50 (Jakarta), 21:20 (Banten), and 23:27 (West Java).

    PLN has also announced that the company would compensate affected customers by reducing August's electricity bills by 20 to 30 percent.   

    On Sunday, millions of PLN customers in Jakarta, West Java and Banten had to live without electricity due to a massive blackout caused by interference to the company's 500-kV high-voltage power transmission line in Ungaran-Pemalang. 

    After further investigations, it was suspected that the interference was caused by an explosion at a high-voltage power transmission line, as witnessed by residents of Malon Village in Gunungpati, Semarang City.
