Regulations 12 and 50 on the utilisation of Renewable Energy for the Provision of Power
Regulation 12 sets the tariffs for solar, wind, hydro, biomass, biogas, city waste to energy, and geothermal power plants. It stipulates that a renewable tariff is capped at 85% of the electricity supply costs (BPP) for the region in question, and 100% of BPP for geothermal and city waste to energy plants, provided the regional BPP is higher than the national average. If the regional BPP is lower than the national average, then the tariff is capped at 100% of the BPP, unless otherwise agreed in the case of geothermal and city waste to energy plants. The purpose of this rule is to reduce the average BPP (i.e., the cost of generation) across Indonesia.
Regulation 50 formally replaced Regulation 12.
