LOAD DISPATCH AND REPLACING DIESEL BY GAS POWER PLANT TO REDUCE PRODUCTION COST OF POWER GENERATION IN BALI ISLAND

Abstract

Bali Island is powered from three power plants and from Jawa Island through marine cables. The power plant in Bali use diesel fuel which result in high production cost. Meanwhile the production cost at Jawa Island is lower because most of power plants use coal fuel. Supply from Jawa Island is limited 200MW but now days use as peaker and supply from diesel power plants in Bali which are mostly old machine run in full power. This condition has caused high production cost. Therefore we proposed to change the load dispatch and replace the old diesel by gas power plant. The simulation has shown a much lower production cost. The lowest cost is found for the transfer Jawa-Bali in optimum capacity.
