Electricity in Indonesia is provided by either independent  or state-owned power producers, and subsequently  distributed to households and businesses throughout  the Indonesian archipelago by a state-owned enterprise.

Historically, power outages occurred when the power  generator in the power plant had been damaged  or temporarily halted due to a safety consideration.  Inside a power generator, the counterweight, a critical  component, relies on long bolts to connect it to its  rotating parts which move at the speed of 600 rpm. If just one of the long bolts breaks, the power generator  will be disrupted or may even be damaged which could  either take a long time to be repaired, or worse, require  a replacement.
