Java-Bali?s grid suffers power supply shortage of 560 MW: PLN

PLN?s president director Eddie Widiono said in Jakarta Friday that blackouts were expected to begin again in several parts of Java and Bali as several potential power plants were being repaired. However, further blackouts could be prevented, except in Surabaya, East Java, following the company?s move to maximize the power supply from Mrica hydropower plant in Central Java.
?The Tambak Lorok combined cycle power plant has already been completely repaired,? he said, adding that improvement regarding operation arrangement has already been made.
Blackout still occurs in Surabaya, East Java that affects industrial customers due to the lowering power supply from Gresik combined cycle power plant. The plant uses oil to generate the plant instead of gas following the explosion of gas pipeline owned by state oil and gas company Pertamina in Porong, Sidoardjo, East Java.
Rolling blackouts occurred in several parts of Java and Bali for consecutive two days since Wednesday due to the reduction in power supply as the result of damages suffered by Paiton coal-fired power plant?s Unit 8 and Suralaya coal-fired power plant?s Unit 6.
Paiton coal-fired power plant operated by Paiton Energy Persada failed to work normally November 7, 2006 but as of yesterday (Nov. 24), its damage could not be handled.
Suralaya coal-fired power plant operated by Indonesian Power, a subsidiary of PLN, whose operation was disrupted by the damage, can now operate normally, following intensive repair.
Tanjung Jati B coal-fired power plant that started operation last month also failed to operate normally due to a problem with its condenser. ?We are still waiting for the spare part. Hopefully, the spare parts will arrive in the next two weeks. For the time being, the plant can operate but its power outlet is below the capacity,? said the plant?s operational manager Affianto Hapsoro. (godang)
