  • Electrification Ratio: 73% (Java Island Electrification ~100%)
  • Electricity Source: 48% Coal, 22% Gas, 12% Oil, Hydro 11/7%
  • Electricity Subsidy: 4% from National Budget (noted Oil Subsidy 14%)

  1. Supply and Demand. The demand of energy is always increasing, while the supply is limited, increasing population. (Economic Issues)
  2. Price of electricity, price is increasing, therefore need a subsidy. Impact to government budget (Policy Issues)
  3. Dependency on Fossil Fuel, Renewables is very small ~10% (Tech Issues)
  4. Distribution, 80% power plant in Java (Politic Issues, Regional Autonomy)
  5. National issues (energy security, green/clean energy awareness, industry, investment, image/branding)

Additional: Data availability & reliability Issues: the data seems inaccurate, don’t expect detail level, of course calculation might be wrong. Even IEA said that to have accurate data is difficult
