  1. PATANCHERU DSM STUDY No. of services EHT HT HT = = = = • 107 • 132 kV • 33 kV • 96 11 kV (out of 107 only 67 are operational) Total CMD = 40,422 kVA

  2. REFERENCE BASIS FOR UTILITY IMPACTS ESTIMATION • Cost of Saved Capacity (CSC), Rs/kW or Rs./kVA = • Cost of Saved Peak Capacity (CSPC), Rs/kW or Rs./kVA = • Cost of Saved Energy (CSE), Rs/kWh =

  3. 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.)

  4. 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

  5. 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

  6. 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%.
