Can We Think in this Direction? • Loss to MSEDCL as Distribution Co . – Total Power Purchase =1,00,000 MUs/Yr – 1% Loss of MSEDCL= 1000 Mus – Av. Cost of Supply= Rs.5.56/Unit – Revenue Loss for 1% Loss=556 Crs/Yr – Present AT & C Loss of MSEDCL= 18.41 % – Permissible loss for such utility= 13.5 % – Yearly We are loosing revenue of Rs. 2700 Crs (Approx)/Yr ------------------------------------------------------------------------------ – One Units Saved is two units generated? – Allied Issues: • Capital Cost, Fuel Cost • Pollution • Transportation • Plant Load Factor • Administrative & General Expenses. • ROW & Land & Forest Problems ---------------------------------------------------------------------------------------------------------- Loss reduction Means Increase in Supply Side Efficiency murharikele@gmail.com 11

Reasons: AT&C Loss Technical Loss Commercial Loss Universal Service Obligation Metering: Large scale rural Theft – hooking electrification Tampering of meter Ad-hoc expansion without Old/electromechanical proper planning meters Old technology & fragile Nature & Locations of meters infrastructure Billing Too many transformation Inaccurate Reading stages Low power factor Methodology of billing Improper load management Average/in accessible cons. Improper location of DTC Improper tariff & Wrong calculations Substandard material Collection Poor construction methods Payment mode & facilities Non-effective disconnection Loss of opportunity by any reason, to serve consumers is biggest loss of utility 13 murharikele@gmail.com
