Effect of Using Low Range Calory Coal on Electricity ...

More than IDR 1.5 B have been saved by replacing the original coal of typical 5000 kcal/kg (ar) with LRC, equivalent to around 1.8 TWh power generation, during June 2020. The success of this coal switching operation can be applied in other coal-fired power plants in Java-Bali grid, to obtain a better electricity production cost.
