Condition of System

Power needs of Lampung Province almost all (99%) supplied by P3B Sumatra through 150 kV transmission network in Southern Sumatra Interconnection System (Sumbagsel) and the rest is supplied by isolated power plants scattered across the province of Lampung like: System of Bengkunat, Simpang Causeway, Pulau Sabesi , Krui, Pugung Tampak and Wiralaga

Of the seven systems that supply electricity in the province of Lampung, 4 systems (System Bengkunat, Pulau Sabesi, Pugung Tampak and Wiralaga) is in “Alert” and 3 other systems (System Sumbagsel, Krui and Simpang Pematang) are in the condition of “deficit” .

Currently Lampung Province electrification ratio just reaches 48.82% and the ratio of electrified villages by 100%. The PLN waiting list has reached 76,025 request or for 88.3 MVA.

 Balance of Power

Provinces of Aceh, North Sumatra, West Sumatra, Riau, Riau Islands, Bengkulu, Jambi, South Sumatra and Lampung electrical systems have been well interconnected with the electric power transmission lines 150 kV System, known by the name of Sumatra system. Thus, the balance of power throughout the province represented by the balance of power of Sumatra system, where in 2010 the capacity of the system can not meet peak loads that exist so that a deficit of 460 MW. As for the following years the condition of Sumatra System is in good condition.

Additional Infrastructure Plan for Electricity

The assumption of population growth estimated at 0.9% per year and the economic growth of 6.2% per year, so assuming the electrical energy demand is expected to grow at an average of 10.3% per year.

In an effort to meet the needs of electricity in the province of Lampung, it has been planned additional electricity infrastructure from the year 2010-2014 as follows:

  • Power plants of 664 MW
  • Transmission of electricity 1056 kms
  • 650 MVA substation
  • new renewable energy program (EBT) and network:
    • PLTS 50 WP is spread as much as 57,500 units
    • Centralized PLTS 15 kW 8 units
    • PLTMH 1650 kW
    • The 1540 distribution substation units (78 250 kVA)
    • Medium Voltage Network 7000 kms
    • Low Voltage Network 6290 kms.
