FLI CALCULATION UNIT 1-2
Basic concept of FLI calculation is “Risk & Profit Sharing” between PLN and CJP.
FLI consists of (i)Fixed Portion (“FLIb”) and (ii)Variable Portion (“D”).

[FLIb] = (Expected Proft by operation of TJB on FLIb Determination Date)
= {(Expected revenue by electricity sales) – (Generating Costs)}

Expected Fuel
Cost (Fb)
