The fragility of the Java-Bali power grid was once again emphasized when large areas of the two islands suffered "brown outs" or temporary suspensions of power on Wednesday evening, November 8, 2006, when the interconnecting power system experienced a 500 mega watt power deficit.
The latest power system failure follows by approximately 3 weeks an island-wide outage that occurred on October 16, 2006.
According to Tempo Interaktif, the deficit occurred when the Cilegon Power Station (240 MW) shut down due to a lack of gas supplies and the Cirata Power Station at Purwakarta (8 x 125 MW) reported insufficient water at its dam sites to drive its water turbines.
Other power stations reporting technical difficulties included Unit #8 at Paiton (600 MW), Unit #2 at Cilicap (300 MW), Unite #1 Muara Tawar Steam Turbine (180 MW) and Unite #2 Gresik Steam Turbine (170 MW).
Those areas affected by the staggered "brown outs" in the Bali-Java power grid were Ponorogo, Madium, Jember, Malang and Pasuruan in Java. Meanwhile, Singaraja, Badung and Jembrana were among those areas affected in Bali.
