Interventions  Feeder separation : Jyoti Gram Yojana  Around 576/ 2000 in Rs.350/1200 Cr.  24x7 power supply to villages  8 hrs. a day power supply to farm-sector  Innovation of Special Design Transformers  Establishment of Area Load Dispatch Centre  Creation of Energy Management Centre

Regrouping of Ag- feeders  Analysis of total load, peak & off peak demand  Regrouping of ag-feeders: 16 to 35 to 59  A group to have about 50 MW of demand  Range of Max m & Min m demand in MW changed  1993 & 1152 (Gap:801MW) to 2070 & 1687(Gap:383MW)  Flattened load curve resulted

GEDA norms for EE Pumps Rating, HP Discharge LPHx1000 Declared overall Eff. Min. overall Eff. for field condition >57%>54.15% >61%>57.95% The above mentioned Overall Efficiency is minimum required for Field condition as per GEDA Norms.

IRMA Findings  Only 21% of EE pumps of average age of 1 yr and 35% of average age of 3 months met with GEDA efficiency norms  Increase in failure rate with age may be related to poor design efficiency of the pumps.  EE pumps are more energy efficient (combined median 49.82%) than non EE Pumps (combined median 40.87).

On supply side:  Providing LT capacitor  Installation of APFC panels  Feeder bifurcation: 893 feeders  HVDS: 7439  Providing amorphous transformers DTRs of GIDC, Urban, Industrial & JGY feeders  Load balancing of DTR  Mass awareness programmes
