System conditions
Electricity needs are served in DKI Jakarta Province of energy transfer from the Java-Madura-Bali (Jamali) interconnection system as the main supplier through SUTET network (500 kV) and SUTT (150 kV and 70 kV), in addition to the supply of PLTU-PLTGU Muara Karang and Priok. Jamali system in a condition of “Alert”.

Additional Electricity Infrastructure Plan
The assumption of population growth in Java Madura, Bali an estimated 1% per year and GDP growth for the same period is projected at 6.1% per year, so assuming the electric energy demand growth is expected to grow at an average of 10.0% per year.
In an effort to meet the needs of electric power in the Province of Jakarta, it has been planned additional electricity infrastructure from the year 2010-2014 as follows:
- Power plants of 1437 MW (about 694 MW is expected to be operational in 2010)
