JAKARTA - PT PLN (Persero) has successfully fully operated the Muara Enim Extra High Voltage Air Line (SUTET) 275 kilovolts (kV) and two Extra High Voltage Substations (GITET).

These two infrastructures are known to contain a Domestic Component Level (TKDN) of more than 90 percent.

The operation was marked by the provision of a second line of voltage (energy) connecting Muara Enim-Gumawang by the PLN of the Southern Sumatra Development Main Unit (UIP SBS) on Saturday, November 2, after previously the first line was successfully operational on May 7, 2024.

PLN's New Renewable Project and Energy Management Director, Wiluyo Kusdwiharto explained, the operation of the Muara Enim-Gumawang 275 kV SUTET will further strengthen the electricity system on the island of Sumatra, especially the South Sumatra and Lampung regions.
