🇮🇩 Indonesia Energy Profile #1 Thermal Coal Exporter #2 Geothermal

Indonesia's Coal Paradox

Indonesia is simultaneously the world's largest thermal coal exporter (by volume) and one of the countries most vulnerable to climate change — its 17,000 islands, 40 million coastal residents, and agriculture sector face severe sea-level rise, coral bleaching, and extreme weather threats. This paradox defines Indonesia's energy transition challenge.

Domestic mandate: Indonesia's government mandates that domestic coal prices are capped for the state electricity company PLN ("domestic market obligation"), effectively subsidizing coal electricity and creating a structural barrier to renewables. This policy makes Indonesian electricity among the cheapest in Southeast Asia but locks in coal dependence.

Indonesia's Geothermal Treasure

Indonesia sits on the "Ring of Fire" with more geothermal resource potential than any country in the world (~28 GW technical potential), yet only 3.4 GW is installed — just 12% of potential. Major barriers include high upfront drilling costs ($10–30M/well), exploration risk, remote locations, and difficult permitting in forested areas (Indonesia's geothermal resources often overlap with protected forests).

Key geothermal fields include Sarulla (Sumatra, 330 MW — world's largest single contract geothermal plant at commissioning), Salak (Jawa Barat, 377 MW, Pertamina/KSPC), and Kamojang (Jawa Barat, 235 MW, oldest field, since 1983). Government target: 7 GW geothermal by 2030.

Just Energy Transition Partnership (JETP) — Indonesia

At COP27 (2022), Indonesia signed a $20 billion JETP agreement — the largest in the world — with the United States, Japan, Canada, Denmark, EU, France, Germany, Italy, Norway, UK. The deal aims to limit Indonesia's power sector emissions peak to 2030 and achieve 34% renewables by 2030 (vs ~23% current target).

Implementation challenges: Indonesia's JETP faces significant obstacles: PLN's coal-heavy balance sheet, domestic coal industry political power, grid infrastructure gaps, and a policy environment that requires Indonesian coal receipts to fund social programs. Progress as of 2024 has been slower than the JETP's ambitious targets.

Indonesia's Nickel — The EV Battery Gambit

Indonesia holds the world's largest nickel reserves (~21% of global), primarily in Sulawesi and Halmahera. In 2020, Indonesia banned raw nickel ore exports, forcing investment in domestic processing — a bold industrial policy move that has attracted $15B+ in Chinese investment in nickel smelting and battery material production.

Environmental cost: Nickel smelting is highly energy-intensive and currently powered by coal (often dedicated coal plants built alongside smelters). The HPAL process for battery-grade nickel also generates large volumes of toxic slurry. Indonesia's nickel boom is paradoxically powered by coal — undermining EV battery "green" credentials.
