According to the Electricity Supply Business Plan (RUPTL) 2021-2030, coal will still dominate Indonesia's energy mix for the next eight years.
In the RUPTL, PLN (state-owned electricity company) also projects that the national coal-fired power generation capacity will increase from 194,558 GWh in 2021 to 264,260 GWh in 2030.
On the other hand, the government aims to gradually cease operations of several coal-fired power plants (PLTU) by 2040 to reduce greenhouse gas emissions.
"The early retirement mechanism for coal-fired PLTUs will be implemented gradually, both naturally and through accelerated retirement, replacing them with new renewable energy," said PLN President Director Darmawan Prasodjo in a press release on Wednesday, October 19, 2022.
