- PLN is already using the bioenergy of the Steam Power Plant through cofiring technology.
- PLN has produced up to 487 MWh of green energy from the cofiring program.
- This achievement is proof of PLN’s seriousness in supporting the government in accelerating the use of new and renewable energy towards the target of 23 percent by 2025.
PLN, together with the Ministry of Energy and Mineral Resources and state-owned enterprises, held a bioenergy seminar on June 30, 2022. The seminar was themed “Increasing the NRE Mix by 23 percent through the Sustainability of Cofiring Fuel Supply and Bioenergy Generators.”
Currently, PLN is already using the bioenergy of the Steam Power Plant through cofiring technology. Through this cofiring technology, PLN can reduce its dependence on coal and produce cleaner energy.
Cofiring is a technology to substitute coal with biomass as a fuel for steam power plants. This biomass can be sourced from energy crops, plantation waste, agricultural waste, carpentry waste, and even domestic waste.

PLN has produced up to 487 MWh of green energy from the cofiring program. The achievement in 2021 is 269 MWh, while from January to May 2022 it is 218 MWh. And until May 2022, cofiring technology has been implemented in 32 steam power plants throughout Indonesia.
This achievement is proof of PLN’s seriousness in supporting the government in accelerating the use of new and renewable energy towards the target of 23 percent by 2025. PLN has a very significant role in achieving this target. In accordance with the roadmap contained in the 2021–2030 RUPTL, PLN will also increase the portion of clean energy-based generators through co-firing technology.
In the implementation of cofiring, the PLN Group has built a supply chain for the supply of biomass raw materials. This is done through mentoring, development, the cultivation of energy plants, and the use of waste. Waste that can be used includes sawdust, woodchip, corncobs, and solid recovered fuel (SRF) from waste. In this case, community participation is needed in the management of waste and energy plants as the raw material for the biomass.
In 2022, it is estimated that the need for biomass for cofiring fuel will reach 450,000 tons. Then, in 2023, it will increase five times to 2.2 million tons of various types of biomass. To maintain the sustainability of the supply of biomass raw materials, collaboration is needed both between SOEs and other stakeholders.

PLN has obtained supply certainty from the synergy of SOEs, regional governments, and even the private sector. According to the President Director of PLN, collaboration between PLN and local governments can achieve two targets at once. First, helping the local government to be able to process municipal waste into an energy source that has economic value. Second, PLN requires biomass to support the co-firing program at the steam power plant. With this collaboration, city waste that was previously allowed to accumulate can be processed together to become a domestic energy source.
PLN will gradually continue to apply co-firing technology to 52 steam power plants with a total capacity of 18 GW by 2025. To support this program, PLN requires a supply of biomass to reach 10.2 million tons per year by 2025, with carbon emissions of 11 million tons of CO2 and greenhouse gases annually. Later, this program can reduce carbon emissions by 11 million tons of CO2 and greenhouse gases every year.
