ANALYSIS OF DSM MEASURES INVOLVED


Identification of Applicable Energy Efficient
Technologies (EETs)


Analysis of Technical and Economic Viability of
EETs and DSM Measures


Consumer Impacts (Energy Saving, Demand
Saving, Cost Saving, Investment, Payback
Period, etc.)


Utility Impacts (Demand Saving, Energy Saving,
Measure Cost, Cost of Saved Energy (CSE),
Cost of Saved Capacity (CSC), etc.)

REFERENCE BASIS FOR UTILITY IMPACT ESTIMATION


T&D Loss Factor (TDLS) is taken as 0.10
corresponding to T&D Losses in the System for
EHT and HT Segments


Capacity Utilisation Factor (CUF) is taken as
0.78, being the PLF of Thermal Plants


Peak Capacity Utilisation Factor (PCUF) is taken
as 0.90


Utility Discount rate is taken as 9%. This is
based on an Interest Rate of 15% and Inflation
Rate of 6%.
