Central Java Province

System Conditions

Electrical system in the province of Central Java is a part of the system interconnection of Java-Madura-Bali. The main supply for the needs of electric power in Central Java province other than the transmission system 500 kV and 150 kV is the power plant / PLTGU Tambaklorok, Mrica Hydroelectric, PLTU Cilacap, and PLTP Dieng.

Currently electrification ratio of Central Java province has reached 71.24% and the ratio of electrified villages by 100.00%. While the PLN waiting list has reached 136 588 request or of 110.2 MVA.

Balance of Power

Province of DKI Jakarta, Banten, West Java, Central Java, DI. Yogyakarta, East Java, and Bali have been well interconnected on electric power transmission lines 150 kV and 500 kV are known by the name of the Java-Madura-Bali  Interconnection System. Thus, the balance of power throughout the province represented by the balance of power of Java-Madura-Bali interconnection system, where in 2010 and 2011 systems are in good condition, whereas in 2012, 2013 and 2014 the capacity of the system can not meet peak loads that exist so that experiencing deficit.

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 Central Java Province, it has been planned additional electricity infrastructure from the year 2010-2014 as follows:

  • Power plants of 3780 MW (about 630 MW is expected to be operational in 2010).
  • Transmission of electricity 2104 kms (including the Province of Yogyakarta).
  • 6616 MVA Substation (including the Province of Yogyakarta).
  • new renewable energy program (EBT) and network:
    • PLTS 50 WP is spread as much as 14,550 units.
    • Centralized PLTS 15 kW 9 units.
    • PLTMH 900 kW.
    • The 1175 distribution substation units (62 500 kVA).
    • Medium Voltage Network 3690 kms.
    • Low Voltage Network 3350 kms.

D.I. Yogyakarta Province

System Conditions

Electrical system in the province of D.I. Yogyakarta is a part of the system interconnection of Java-Madura-Bali. The main supply for electricity demand in the province of DI Yogyakarta is the transmission system 500 kV and 150 kV.

Currently electrification ratio D.I. Province Yogyakarta has reached 84.48% and the ratio of electrified villages by 100.00%. While the PLN waiting list has reached 4562 requests or of 6.4 MVA.

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 electricity in the province of DI Yogyakarta, it has been planned additional electricity infrastructure from the year 2010-2014 as follows:

  • Transmission of electric power into the recap of Central Java Province.
  • Substation  included in the recap of Central Java Province.
  • new renewable energy program (EBT) and network:
    • PLTS 50 WP is spread as much as 14,550 units.
    • Centralized PLTS 15 kW 4 units.
    • PLT wind 320 kW.
    • The distribution substation into the recap of Central Java Province.
    • included in the Medium Voltage Network recap of Central Java Province.
    • Low Voltage Network included in the recap of Central Java Province.
