Indonesia-based state-owned power utility Perusahaan Listrik Negara (PLN) is looking for additional supply of 28 million metric tons of coal every year after it received an order from the government to construct coal-fired plants together producing 7,000MW of electricity.

The government has plans to develop a total of 15,000MW of electricity through different sources such as coal, geothermal, and hydro.

PLN has also been asked to depend less on diesel and use cheap energy sources like coal to produce electricity, reported The Jakarta Globe.

Perusahaan Listrik Negara coal director Helmi Najamuddin said, "Every 1,000 megawatt of power capacity consumes 4 million tons of coal a year."

According to Helmi, the utility will set a tender to seek coal supplies if the government issues relevant regulation.

Currently, almost 60% of Indonesia’s electricity is produced using coal as a source.
