Indonesia, as an archipelagic nation with a tropical climate, is blessed with ample renewable energy (RE) resources, including geothermal, hydro, solar, biomass, and wind energy. However, the RE share in the power mix is stagnating around 11%. At the same time, it is the largest thermal coal-exploring country (400 million tonnes in 2020), with an annual average of coal production reaching as high as 600 million tonnes. Around a quarter of the total coal production is utilized for domestic use in coal-fired power plants, translating to at least 50% of Indonesia’s total installed capacity and contributing to 34% of Indonesia’s total greenhouse gas (GHG) emissions. The need to reduce GHG emissions from the energy sector, particularly by reducing coal use, thus becomes more urgent than ever considering the newly announced national goal to reach net zero emissions by 2060 on top of the nation’s commitment to reduce its GHG emissions by 29% below the business-as-usual scenario by 2030.
