PLN SUFFERS POWER DEFICIT OF 460.2 MW

Jakarta, Nov 17 (ANTARA) - State-owned electricity company PLN in October 2009 suffered a power deficit of 460.2 Megawatts, according to data obtained from PLN on Monday.

The data showed that of the 24 power distribution systems, 11 experienced a power deficit, two were under an alert status and the other two were in normal condition.

According to the data, the state-owned power utility company divided the conditions of its power distribution systems into three categories, namely normal, on alert and in deficit of power supply.

In the normal condition, PLN does not impose a rotating power cut because it has enough power reserves for operations. The alert condition indicates that PLN does not impose a power cut but it has the potential to cut power because its power reserves are smaller.

In the meantime, the deficit condition causes PLN to impose rotating power outage because its capacity to supply electricity is smaller than the needed one during peak load, or there is a disturbance in the transmission system.

The 11 power supply systems which experienced power distribution deficits in October were those of the Southern Sumatra system suffering a deficit of 198.3 MW, South Sualwesi (145.7 MW), Northern Sumatra (70 MW), Minahasa (27.51 MW), Tanjung Pinang (7.4 MW), Poso (1.71 MW), Sampit (0.8 MW), Kendari (2.1 MW), Palu (5.96 MW), Ambon (0.56 MW) and Singkawang (0.16 MW).

The systems which were still on the normal conditions were the Java-Madura-Bali and the Bontang systems.

Those experiencing the alert status were the Banka, Belitung, Batam, Pontianak, Lombok, Barito, Mahakam, Gorontalo, Kupang, Ternate and Jayapura systems. *
