This is part of PLN’s ambition to achieve carbon neutrality by 2060, its senior vice president Darmawan Prasodjo said in a televised hearing in parliament.
The Indonesian government aims for 23% of energy to come from renewable sources by 2025, up from around 11% last year, but progress on renewable energy projects has been slow.
“We are building a timetable for phasing out coal-fired power plants,” Darmawan said.
The first phase of this will see the closure of three coal-fired power plants by 2030 with a combined capacity of 1.1 gigawatts.
These are the Muara Karang power station in the capital Jakarta, the Tambak Lorok power station in Semarang, the largest city in central Java, and a gas and coal power station in Gresik, a regency of East Java.
In 2035, PLN intends to retire its conventional power plants with a total capacity of 9 gigawatts, Darmawan said.
By 2040, “supercritical” coal-fired power plants, or those using less polluting technology, with a total capacity of 10 gigawatts, will be closed.
The final phase of the coal phase-out will see its “ultra-supercritical” coal-fired power plants shut down by 2056.
“Then we will achieve carbon neutrality in 2060,” said Darmawan.
The fourth most populous country in the world has a potential capacity of over 400 gigawatts for sources such as hydropower, solar and geothermal energy, but only about 2.5% had been used in 2020, according to government data. .
Despite the pressure for greener energy use, President Joko Widodo last year urged ministers to speed up plans to build power plants to improve the country’s downstream coal sector.
