  1. Sustainable Hyderabad Project: Implementing cooperative and technical solutions to increase energy efficiency in irrigation Technical Evaluation and Analysis of Energy Conservation, System Improvement and GHG Emissions Reduction from Capacitor Installation on Agricultural Pumpset Motors February 2013

  2. Project Scope • DISCOM – Co-Operative Electric Supply Society (CESS) • No. of Sub station – 2 • Vattemula Sub-station 33/11 KV • Sanugula Sub-Station 33/11 KV • No. of Feeder – 4 • Namiligondapally Feeder 11 KV • Vattemula Feeder 11KV • Sanugula Feeder 11 KV • Lingampet Feeder 11 KV • Selected feeder for capacitors installation: • Namiligondapally Feeder 11 KV • Sanugula Feeder 11 KV • Total no. of DTR under Namiligondapally & Sanugula feeder: • 100 KVA – 35 No. • 63 KVA – 7 No. • Total Capacity of DTRs – 3941 KVA • No. of Villages – 5 • Namiligondapally • Vattemula • Kothapet • Sanugula • Ramaraopali cBalance Solutions Hub

  3. Project Scope • Total No. of Pumps – 809 • Total Capacity of all pumps – 3028 HP • Pump Type Classifications: cBalance Solutions Hub

  4. Study Scope • DISCOM – Co-Operative Electric Supply Society (CESS) • Sub station- Vattemula Sub-station 33/11 KV • Feeder – Namiligondapally Feeder 11 KV • Total no. of DTR under Namiligondapally feeder: • 100 KVA – 13 No. • 63 KVA – 3 No. • Total capacity of DTRs – 1489 KVA • Total area covered – 10.07 Kms • Total No. of Pumps – 325 • Total Capacity of all pumps – 1176.5HP • Pump Type Classifications: cBalance Solutions Hub

  5. DTR Selection Methodology • Ideal DTR defined as DTR with 33% distribution across categories A, B, C • Deviation from ideal distribution calculated for each DTR: • = (% of Category A Pumps – 33%) + (% of Category B Pumps – 33%) + (% of Category C Pumps – 33%) • DTRs with lowest ‘sum of differences’ and mix of overloaded / non-overloaded DTRs selected for study cBalance Solutions Hub
