Besides the three plants, Indonesia Power, one of the largest electricity power generating companies in the country, operates five other power plants - at Tanjung Priok in Jakarta, at Kamojang and Saguling in West Java, Mrica and Semarang in Central Java, Perak in East Java, and Bali, with a total capacity of 8,888 MW.
Data from the Energy and Mineral Resources Ministry shows Indonesia has total reserves of coal of 104.7 million tons. The country's geothermal capacity is 27,510 MW, or about 40 percent of the world's geothermal capacity.
However, the great potential is nowhere near fully utilized domestically, while 70 percent of the country's coal is earmarked for export.
Young Entrepreneurs' Association (Hipmi) chairman Eric Aksa urged the government to speed up coal production for domestic use, saying it would help the private sector survive during the global economic crisis, because coal had "competitive advantages". The authorities should change their paradigm concerning the use of coal as a revenue booster. We should now treat it as a factor to boost the national economy. China and India had taken the approach of prioritizing domestic demand.
