Electricity in Indonesia
Find out about power supply and electricity providers in Indonesia...
Indonesia's standard electricity supply is usually 220 volts AC with a frequency of 50 hertz, although 110 volts is still used in some areas. Conversion to 230 V is in progress throughout the country. For other equipment a transformer or adaptor is required unless the appliance has a multi-voltage option.

For diagrams see:
Indonesia uses both screw type and bayonet light bulbs, with screw fittings being the most common. Light bulbs are energy efficient.
Indonesia uses the PAL-B television system which will be abandoned in 2018. Since 2008, broadcasts have been available simultaneously with DVB-T.

Electricity in Bali, Indonesia
Voltage can be unstable in Indonesia in that it has many spikes and surges. Some electrical devices, for example computers, washing machines and refrigerators, may not work and/or will be damaged after a while.
For these reasons it is worth considering purchasing an AC voltage stabiliser. This should be 20 percent more than the power supply. So for a home with a power supply of 5,500 Watts (5.5 KW), a stabiliser for 6,600 Watts is required. An average stabiliser works between 140 volts and 270 volts.
In some areas in Bali during peak hours, for example from 18:00 to 22:30, voltage can be reduced to below 140 volts. Without a stabiliser the power supply starts and stops frequently and many electrical devices will stop working. If the problem is frequent, contact PLN.
Before renting accommodation, check the power supply wattage. For example, a home with two air conditioning units, a refrigerator, water pumps and other common electrical devices will need a minimum of 4,400 Watts. Almost all houses in Bali have a power supply lower than 4,400 watts. Check the wattage with PLN before signing any contracts. It is possible to request an upgrade of the power supply, however, there is a waiting list and it can take up to one year, due to lack of power in the area.
Power outages are very frequent in Bali and can be caused by two different reasons.
- Rotating outages occur when works and maintenance are carried out over several months and the outages rotate between different areas, usually twice a week, each time for up to seven or eight hours in each area.
- There are also power outages due to tropical storms, flooding and small maintenance.
Many companies, hotels, restaurants and private individuals use Gensets (generators) to produce electricity during outages. Gensets can be either gas or diesel, with the diesel Genset being the most common. Gensets are easy to find and can be purchased in most hardware stores.
