FLI CALCULATION

5 ~ 55%**

*: for the purpose of this presentation, not including EADTX and FLI Adjustment Amount. **: 5 ~ 55% of a weighted average of FLIb during Phase 1 is applied for FLIb during Phase 2 ***: 5 ~ 100% of FLIb during Phase 1 is applied for FLIb during Phase 2

5 ~ 100%*** 3 years

12 years (Phase 1) 8 years (Phase 2) FLIb varies every 3 years

FLIb is fixed during whole lease period : FLI b）

Phase 1 : D (calculated every 6 months)

For COD: average of “OM” used to refer to the audited report of IP and PJB [Rp/kWh]

For others (every 3years): O&M Costs [Rp./kWh] for the payment period including FLIb Determination date

For COD: (average cost of fuel [Rp./kg] purchased by PLN prior to COD) x (Unit Heat Rate) / (HHV of fuel) For others (every 3years): Fuel Costs [Rp./kWh] for the payment period including FLIb Determination date
