REFERENCE BASIS FOR UTILITY IMPACTS ESTIMATION
 Cost of Saved Capacity (CSC), Rs/kW or Rs./kVA
Total Measure Cost (Rs.)
= Saved Peak Capacity kW or kVA PCF  1 TDLF  CUF

 Cost of Saved Energy (CSE), Rs/kWh
Total Measure Cost (Rs.)  CRF
= Annual Energy Savings (kWh)
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.)
OVERVIEW OF APPLICABLE DSM MEASURES
 Power Factor Improvement at Plant Sub-Station
 Replacement of Conventional Ballasts (Chokes) on
Fluorescent Lamps (FTLs) by Low Loss Ballasts
 Replacement of GLS Lamps by FTLs with Low Loss
Ballasts
 Replacement of GLS Lamps by Compact Fluorescent
Lamps (CFLs)
 Replacement of HPMV Lamps by HPSV Lamps
 Lighting Voltage Controller
 Soft-starter/Energy Saver
 Replacement of Pump by High Efficiency Pump
 Replacement of Fan by High Efficiency Fan
OVERVIEW OF APPLICABLE DSM MEASURES
 Replacement of Single Stage Air Compressor by Two
Stage Air Compressors
 Replacement of Reciprocating Air Compressor by
Screw Air Compressor
 Replacement of Reciprocating Refrigeration
Compressor System by Centrifugal Compressor
 Replacement of Reciprocating Refrigeration
Compressor System by Screw Compressor
 Replacement of Vapour Compression Refrigeration
System by Vapour Absorption System
(Water-Lithium Bromide)
 Replacement of Vapour Compression Refrigeration
System by Vapour Absorption System (Aqua-Ammonia)
 No Load Energy Saver for Welding Sets
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%.
