On the understanding based on the explanation and briefing given to us, the requirement of this
assignment is to calculate the power / units procured for the purpose of mitigating load shedding
in the areas which were declared ZLS zones so as to fmd the cost of those units.
It is also given to understand that Franchisee is expected to supply everyday for 12 Hours at a
mutually agreed rate and in the event of non-performance of the expected condition; the actual
supply time will have to be considered.
Further it is given to understand that, in the event of the total power regularly ordered from the
Franchisee is in excess of the requirement in the ZLS then in that event, such power shall not be
accounted for as units used for mitigating load shedding in ZLS area and accordingly such units
shall be at the cost of the Distribution Company and not to' be charged to the Consumers of ZLS
area.
Further it is explained to us and as per our understanding, the energy used for mitigating load
shedding in the said area is calculated on the basis of average load and the duration of the planned
load shedding, where the planned load shedding means the proposed load shedding if the ZLS is
not proposed for any area.
Further it is understood that the "average load" referred to in the calculation is in fact not exactly
the "average load" as computing the same is highly complicated and complex process and hence
the average load is considered as the general running load during the period in which the load
shedding is avoided under ZLS.
We have relied on the expert for the technical verification and the appropriateness and
reasonableness of assumptions and methods used and their application are the responsibility of
the expert however we have obtain an understanding of those assumptions and methods to
determine that they are reasonable b~sed on our knowledge of your business and on the results of
our review process.

1) Timings, factors, figures and parameters provided by various units like Corporate
Office, field units are taken as correct at their face value and their authenticity is not
verified.
2) Actual Quantities used from the Grid or given to the Grid are assessed ones and not
actually measured. However the method adopted is the possible one to arrive at the
nearest to the actual figures. Under the circumstances, the factors and figures are not
as accurate but are nearest to the actuals.
3) Average load of feeders were taken as the loads established during previous year
2009-10. Similarly Base losses are taken as observed during the year April 2010 -
March 2011.
1) % distribution and collections losses based on the performance during the year 2009
-2010 for grouping the areas.
2) Average loads of areas concerned
3) Load profile statement
4) MW and MUs requirement sheet to mitigate load shedding as per individual
circulars from Corporate Office and the consolidated statement
5) Statements showing Units purchased, power purchase cost, reliability charges.
6) Calculation of financial implication of Zero Load Shedding Program wherein as per
the information provided, the amount burden for mitigating Load shedding is
Rs.(6.25)Cr, Rs. (6.10) Cr and Rs. (4.99) Cr for the months of January, February
and March 2011 respectively. The total burden for this quarter being Rs.(17.34) Cr.
Based on the above, we state that the documents produced before us does not contain material
arithmetic discrepancies.
