Principles of Tariff FixingCost based , technology specific and
three tiered tariff
Tier 1: Years 1- 6
Tier 2: Years 7 – 15
Tier 3: Years 16 - 20This tariff will be limited to small power
producers ( Capacity up to 10 MW)CEB pays only 90 % of the avoided cost Any difference will be provided by the GOSL
through Sustainable Energy Authority (SEA)

Principle of Tariff Fixing
This tariff have been designed to eliminate the problems of negative cash flows experienced by many small power producers during the period of loan repayment.Tariff will be revised once a year due to rapid changes in the project costs, exchange rates and interest rates, etc. 20 year term of the power purchase
agreement

Three tier tariff estimationEscalation of O & M. This will be calculated using the average of Sri Lanka Consumer Price Index (SLCPI) rates of change and SLRs/USD rates of change for the five preceding years.
Source for SLCPI & SLRs/USD – Central bankThe five year average SLCPI – 8.75
Depreciation of rupee against the USD – 6.11%
