Indonesia, which holds the world’s largest geothermal reserves, is aiming to have a total of 3.35 gigawatts (GW) of geothermal power production capacity by 2030.
Indonesia needs to tap into renewable energy sources, particularly geothermal and solar energy sources, as one of the world's most populous country and a major global emitter is decarbonizing its economy.
“Demand and potential for renewable energy in Indonesia are soaring, it is expected that the Indonesian energy demand will increase considerably,” Coordinating Economic Affairs Minister Airlangga Hartarto said during a JakPost UpClose webinar on Tuesday.
The latest edition in The Jakarta Post’s public webinar series, themed “G20 Energy Transition: Toward Zero-Emission Partnerships”, was held in conjunction with Indonesia’s 2022 G20 presidency.
Edwin Nugraha Putra, executive vice president of electricity system planning at PLN, told the webinar that the state-owned electricity company had designed several strategies to transition from high-carbon energy sources. These included expanding the capacity of its gas-fired power plants, increasing cofiring at its existing coal-fired power plants (PLTU) and converting more power plants from diesel to renewables.
“By the end of 2060, we will put all kinds of renewable energy, including geothermal power and hydropower, in the system. If we still need more, it will come from wind and solar,” Edwin added.
PLN is currently developing a geothermal power plant with an installed capacity of 590 megawatts (MW), consisting of 360 MW generated by PLN and 230 MW generated in collaboration with state-owned geothermal company PT Geo Dipa Energi and state-owned Pertamina Geothermal Energy.
