System Conditions

Electricity demand in the province of North Sumatra almost the entire burden (99.9%) supplied by P3B Sumatra through 150 kV transmission network in Northern Sumatra Interconnection System (Sumbagut). Besides, some regions in North Sumatra is still in small systems such as System of Nias and South Nias.

3 system that supplies electric power in North Sumatra province are in  “deficit” condition (power outages happens to some customers due to installed capacity could be smaller than the peak load).

Currently North Sumatra Province electrification ratio reached 69.68% and the ratio of electrified villages of 84.07%.

 

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, known by the name of Sumatra System. Thus, the balance of power throughout the province represented by the balance of power system Sumatra, 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 Electricity Infrastructure Plan

The assumption of population growth in the province of North Sumatra is estimated to average 1.0% per year while economic growth for the same period is projected at 6.7% per year, so with that assumption the electrical energy demand is forecasted to grow on average by 7.3% per year.

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

  • Power plants of 1986 MW (about 340.8 MW is expected to be operational in 2010)
  • Transmission of electricity 1530 kms
  •  4670 MVA Substation
  •  New & renewable energy program (EBT) and network:
    • PLTS 50 WP is spread as much as 31,700 units
    • Centralized PLTS 15 kW 4 units
    •  MHP 1360 kW
    • PLT wind 320 kW
    • Substation distribution 1400 units (71 250 kVA)
    • Medium Voltage Network 3.610 kms
    •  Low Voltage Network 3.110 kms.
