JAKARTA - PLN Nusantara Power reported that throughout the first half of 2025, the company managed to produce 472.2 GWh of clean energy. This amount is equivalent to reducing carbon emissions by 525 thousand tons of CO2, as a result of co-firing innovations applied to 25 coal PLTUs.

President Director of PLN Nusantara Power, Ruly Firmansyah, emphasized that the company's commitment to supporting the achievement of Net Zero Emission (NZE) in 2060 remains a priority. Not only through the development of renewable energy-based plants (EBT), but also by adopting an effective strategy to encourage the application of clean energy to existing Steam Power Plants (PLTU).

"We have been conducting studies related to co-firing technology since 2018, and have now implemented co-firing in 25 PLTUs spread across Java and outside Java. Several PLTUs outside Java have even reached a co-firing level of up to 100 percent," said Ruly, Wednesday, August 6.

This co-firing innovation, he continued, is a strategic step in realizing clean energy, as well as being part of the PLN's "green booster" program to achieve the national EBT energy mix target. Co-firing is considered a quick and effective solution in reducing carbon emissions and increasing the contribution of green energy without the need to build new plants.

Co-firing is a combustion substitution technique at PLTU, where part of coal fuel is replaced by biomass, which also supports reducing dependence on fossil fuels.

"In addition to reducing emissions, co-firing also has the potential to overcome waste problems and encourage a circular-based economy, where one of the fuel sources can come from solid Jumputan Fuel (BBJP)," explained Ruly.

PLN Nusantara Power has also entered into partnerships with four Japanese companies, namely Toshiba, Sumitomo Heavy Industries (SHI), Mitsubishi Heavy Industries (MHI), and Ishikawajima-Harima Heavy Industries (IHI Corporation), to develop clean energy in generating units through various technologies such as biomass processing plant, co-firing amonia, AQCS (air quality control system), CCUS (carbon capture, utilization and storage).
