GESCOM Aggregate Technical & Commercial Losses

Slide 2:

Introduction Reforms in power sector in Karnataka initiated in 1999 KEB corporatized – KPTCL came into existance in 1999 Transmission and distribution activities unbundled – 5 ESCOMs incorporated from 1 st June 2002. They are BESCOM, MESCOM, HESCOM, GESCOM & CESCO All ESCOMs took over distribution activity from 01.06.2002

Slide 3:

Concept All ESCOMs purchase power from CGS, SGS & IPPs to distribute the power to consumers Consumers billed as per tariff fixed by KERC Energy losses are of two types:- – viz, Technical & Commercial Technical losses: – Due to transmission, iron and copper losses in transformers etc.

Slide 4:

Concept Commercial losses due to theft of energy/illegal extraction of energy/wrong billing. Aggregate Technical & Commercial losses:- Means Yardstick for measuring the efficiency of ESCOMs AT&C losses to be calculated, monitored and remedial measures to be taken Inefficiency in collections and containing losses adversely affects the ESCOMs

Slide 5:

Approach & Methodology T & D Losses - Difference between the Energy Input and Energy Sold Collection Efficiency - Ratio of amount Collected against amount billed. Units realised - Product of Units Billed or Sold AT & C Loss – 1-(Billing Efficiency X Collection efficiency).

Slide 6:

In a simple terms, the formula for calculating AT & C loss can be given as under. AT & C Loss = 1 – Where : Sales = Total sales during the month (in Kwh) as per DCB Energy Input = Units received at Interface points Amount Billed = Demand as per DCB Amount Collected = Collection as per DCB Approach & Methodology Sales (Kwh) Energy Input (Kwh) Amount collected Amount Billed X X 100

Slide 7:

AT & C Losses of Company for the month of June 2009 Energy Input : 453.80 MU Sales : 347.37 MU Demand : 100.360Crores Collection : 098.33 Crores ( Assumed 100% collection of LT1,LT4,LT6, HT1&HT3) AT&C Loss = 1- (Sales/Input X Collection/Demand)100 1- (347.37 MU/453.80 MU X 98.33 Cr/100.36 Cr)100 1- (0.77 X0.0.98) 1-(0.75)100 1-0.75=0.25x100 AT&C LOSS IS 25%

Slide 8:

Calculation at Divisional Level Energy Input : Input energy (in kWh) at all interface points available in the Division (excluding auxiliary consumption of KPTCL owned stations) (+) Energy Imported from adjoining Divisions (-) Energy Exported to adjoining Divisions


How to Reduce loss:- TECHNICAL & COMMERCIAL LOSSES: Proper maintenance of DTCs & LT Lines 100 % Meter Reading and Billing Detecting theft and pilferage Detecting unauthorized installations bringing them to account Opening of test reports with out any delay Periodical rating and calibration of meters Frequent check of meters of High yielding revenue installations Prevention of theft by sealing Terminal cover and body of the meter. Increase in collection efficiency Replacement of MNR meters and fixing of meters to DC installations for all Tariff category. Vigil over MFFs Meter Reading and billing activities
