Guidelines for Energy Accounting of Subdivisions/ Divisions/ Circles/ Zones of MSEDCL

Energy accounting has two basic parameters

1. Input2. Sale or consumption

The difference between Input and Sale is Loss and ratio of this Loss to Input is % Loss

---------------------------------------------------------------------------------------------------------------------------------

Input has four components

1. Input on 33, 22, 11 kV feeders from MSETCL to Subdivisions/ Divisions/ Circles/ Zones ofMSEDCL

Readings (in MUs), submitted by EHV (O&M) circles, will be considered as input to

MSEDCL. In case of any dispute, the same should be resolved by concerned Suptd. Engineers

of MSEDCL and MSETCL or, if needed, by Zonal Chief Engineers of MSEDCL and MSETCL

2. Input on EHV feeders (66 kV & above) from MSETCL to MSEDCL EHV consumers underSubdivisions/ Divisions/ Circles/ Zones of MSEDCL

In case of EHV consumers, jurisdiction of MSEDCL starts from the Billing meter of EHV

consumer, hence MSEDCL Input point in case of EHV consumers is billing meter of

consumer.

3. Input at Distribution network directly to 33,22,11 kV network (33/11 substations, 22kV or11kV switching stations) by other power generators( CPP,IPP or NCE sources like windmill,

bagasse plant, biomass plants, etc) or by MSPGL small hydro power stations like Dimbhe,

Manikdoh, Vindhyachal, Kanher, Yawateshwar, Tervan-Medhe.

In such cases net of energy received by MSEDCL Subdivisions/ Divisions/ Circles/ Zone is

to be taken as input for that particular Subdivisions/ Divisions/ Circles/ Zone. The figures

reported by field offices needs to be exactly same as figures in Energy bill of MSPGCL or bill

of generator and also those appearing in report of CE(Comm) report.

4. Input due to Cross-Over energy exchangeThis energy transaction will be positive for energy import and Negative for energy export. It

is observed that one entity i.e. Subdivisions/ Divisions/ Circles/ Zone reports energy transaction in

the form of import or export, but other Subdivisions/ Divisions/ Circles/ Zone denies or disputes

this import or export.


2/4

For this purpose all cross-over points must be metered.

Installation of meter, maintaining this metering arrangement good & accurate condition,reading & reporting of these meter readings is responsibility of both importer and exporter

Reading reported by importing office i.e. Subdivisions/ Divisions/ Circles/ Zone will form abase for the purpose of energy accounting.

If there is any dispute between two offices under control of one authority regarding cross-overpoint selection, meter installation, meter maintenance, its monthly readings, it will be

responsibility of controlling authority to resolve it.

If controlling authorities are different, it will be responsibility of next higher authority toresolve it.

Disputes between inter-zonal cross-over points shall be referred of CE(IR) Head Office. All such disputes must be resolved before reporting the figures, to avoid unnecessary delay.

-------------------------------------------------------------------------------------------------------------------------------------

Sale has five components

1. HT ( High Tension consumers) SaleHT sale is net sale to all HT consumers (HT + EHV). This is sale arrived after deducting Credit

energy units on account of third party sale from actual energy consumption recorded on meter.

2. LT (Low Tension consumers) SaleLT sale is net sale to LT consumers (except LT-Ag metered and consumers).

3. LT-Ag metered SaleThis is sale to Low Tension Metered Agricultural consumers.

Majority of LT-Ag consumers are billed For the purpose of energy accounting quarterly consumption of metered Ag consumers is

considered.

For first two months of any quarter, LT-Ag consumption units are taken on pro-rata basis (1/3rdof the total consumption of previous quarter for 1st month and 1/3rd for 2nd month)

Actual LT-Ag units become available at the end of the quarter To match the quarterly data, the 1/3rd units considered in 1st month and 1/3rd units considered

in 2nd month are deducted from the total units for the quarter and balance units considered for

the last month of quarter


3/4

4. LT-Ag Unmetered SaleThis is sale to Low Tension Unmetered Agricultural consumers.

At the end of quarter, IT section computes quarterly units consumed by meteredLT- Agricultural consumers in the Zone by excluding all readings other than Normal meter

status readings.

IT section computes average quarterly load of metered Agriculture consumers having normalmeter status in the Zone.

Compute Zone Index (kWH/HP) for the quarter. Compute quarterly consumption of unmetered agriculture consumers with this index

(kWH/HP)

For first two months of any quarter LT-Ag consumption units are taken on pro-rata basis (1/3rdof the total consumption of previous quarter for 1st month and 1/3rd for 2nd month)

Actual LT-Ag units become available at the end of the quarter To match the quarterly data, the 1/3rd units considered in 1st month and 1/3rd considered in 2nd

month are deducted from the total units for the quarter and balance units considered for the

last month of quarter

5. Sale shown against Credit BillingThis is net units given to HT consumers as Credit in their bill against energy pumped by them

in grid (mainly Non-conventional energy sources like wind energy generators)

This is applicable to consumers availing benefit of third party sale. These consumers get net

bill (Actual energy consumed Credit energy on account of third party sale)

For the purpose of energy accounting actual consumption recorded on meters needs to be

taken; hence these units are shown separately.

All sale figures will be final figures reported by IT section

Local IT centers and Head Office IT section must have same figures. Field officers, IT center officers, HO (IT), CE (IR) must ensure that only figures reported by IT

section will be used for energy accounting.

The figures reported by IT center latest by 40th day of the month under report will beconsidered for energy accounting.

Changes if any reported after that will be accommodated at the end of financial year afterreconciliation of data for that year.


4/4

Points to remember

1. As energy accounting report is a part of performance evaluation at every level ofadministration, a due care should be taken at every level.

2. All disputes regarding energy inputs from MSETCL, cross-over point energy transactions,energy sale data from IT section needs to be resolved at lowest possible level.

3. As these reports are submitted to management and further to MERC after approval ofManaging Director, it becomes difficult to accommodate any changes reported after

finalization of report.

4. To avoid such situation all information, modifications, updations must be submitted withintime limits given below

EHV(MSETCL) feeder input data Within 20 days from report under month

EHV consumer consumption data - Within 20 days from report under monthDistribution level input data - Within 20 days from report under monthCross-over point data - Within 20 days from report under monthBilling Data from IT section - Within 40 days from report under month

Only the Information received observing these cut-off dates will be treated as final

guidelines energy accounting
