APPROACH TOWARDS KVAH TARIFF DETERMINATION
Background and Context
1.1. In July 2013, PSPCL had submitted a petition to the Hon’ble PSERC for the introduction of kVAh
tariff on Large Supply (LS) consumers with a minimum connected load of 100 kW. The Hon’ble
Commission had then advised PSPCL to submit a revised petition after including the provision of
introducing kVAh tariff for Medium supply category consumers as well as assessing the impact of
implementing kVAh tariff on all the said consumers on an annual basis.
1.2. In light of the above, this study proposes that kVAh tariff be implemented on the following categories
of consumers:
• Large Supply (LS) Consumers: All sub-categories
• Medium Supply (MS) Consumers
1.3. This report lays out the methodology used for carrying out the analysis for identifying the respective
consumption factors and assessing the impact on consumers, as well as findings from the study.
Data Analysis
1.4. For assessing the impact of implementation of kVAh tariff on the consumers in the above categories,
and estimating the required conversion factor, the billing details from the Meter Reading Download
(MRD) files of LS & MS Consumers for the period FY 2012-13 has been considered.
1.5. The following parameters which have been extracted from the respective MRD files for the analysis:
•
Large Supply (LS) billing data:
•
Tariff sub-category
•
Billing cycle
•
Consumer name
•
Consumer’s connected load
•
Energy consumption in kWh
•
Current SOP
•
Surcharge/rebate due to
Power Factor
•
Average Power Factor

in
Medium Supply (MS) billing data:
•
Billing cycle
•
Consumer’s master key
•
Consumer’s connected load
•
Energy consumption in kWh
•
Current SOP
•
kVAh meter reading
Approach
1.6. In purely mathematical terms, the kVAh recorded by the meter can be correlated to the kWh by the
equation as under:
KVAH = KWH
Power Factor
3|Page
- (1)
1.7. Considering that power factor is always less than one, the kVAh reading recorded in a meter would
always be more than the kWh reading.
1.8. For the purpose of implementing kVAh tariff on all LS and MS category consumers in PSPCL, a
revenue neutral approach has been adopted wherein the overall revenues/bill for a particular
consumer category/sub-category would remain the same as is the case with the current kWh billing
system.
1.9. Therefore, in order to arrive at the kVAh based tariffs in a revenue neutral scenario, we have used a
multiplication/conversion factor, which is normally equal to the desired value of the power factor, and
the equation as:
Tariff KVAH = Tariff KWH x Conversion Factor
- (2)
1.10.
For instance, in the event that in the existing scenario the net Power Factor surcharge/rebate for a
particular consumer category is nil, the conversion factor (CF) would be equal to the power factor
(PF).
Methodology and Assumptions
1.11.
In case of several consumers, the recorded power factor in the billing database is more than one.
Since the tri-vector meters are built on a logic which does not record a leading power factor hence
such readings have been attributed to incorrect meter reading and hence have been ignored in the
current study.
1.12.
Billing data comprising of zero SOP or zero power factor have been ignored for the calculations
as they would skew the findings of the study.
1.13.
LS category consumers:
1.13.1. For LS category consumers, except the data sets as mentioned in the above two points,
the parameters mentioned in Point No. 1.5 have been used as recorded to determine the
current energy bill, net of power factor surcharge/rebate, for all consumers and
subsequently the desired revenue neutral Conversion Factor.
1.14.
MS category consumers:
1.14.1. For MS category consumers the kVAh consumption has not been recorded in the MRD
data. Instead a kVAh reading has been recorded for each consumer category. Therefore, the
KVAH reading recorded in the previous cycle has been subtracted from the kVAh reading
recorded in the current cycle to determine the kVAh consumption.
1.14.2. The KVAH consumption so estimated has been utilized to determine the Power Factor of
the consumer during the current cycle by using the formula provided at point 1.6.
1.14.3. The estimated Power Factor has been used to determine the Power Factor Surcharge /
Penalty as per the applicable slab rates:

1.14.4. Consumers with kVAh reading in current cycle less than that in previous cycle have not
been considered.
1.14.5. Consumers with KWH consumption as non zero but kVAh consumption in current cycle
being equal to that in previous cycle have not been considered.
Achieving Revenue Neutrality
1.15. In order to maintain revenue neutrality by implementation of kVAh tariff for the FY 2012-13, we
have taken into consideration only the following four parameters:
•
kWh Consumption (Recorded values for LS and MS)
•
kVAh Consumption (Recorded values for LS; Determined values for MS)
•
Revenue from SOP (Recorded values for LS and MS)
•
PF Surcharge / Rebate (Recorded values for LS; Determined values for MS)
1.16. The PF surcharge/rebate is added to the revenue from SOP to calculate the ‘net bill’ payable for each
consumer. (Bill attributable to energy consumption and PF)
1.17. The net bill so determined is then divided by the kWh consumption recorded to arrive at the ‘net per
unit billing rate’ of the consumer
1.18. The ‘net per unit billing rate’ is then multiplied to the ‘conversion factor’ (as elaborated in point 1.9)
to determine the ‘per unit KVAH tariff’ applicable on the consumer.
1.19. The ‘per unit kVAh tariff’ so derived is multiplied to the kVAh consumption recorded for each
consumer in the billing database to arrive at the revenue from each consumer after implementation
of kVAh based billing. This revenue is added up to arrive at the total revenue of PSPCL in case of
adoption of kVAh tariff. Then the assumed Conversion Factor (CF) is varied in multiples of 0.001
and the corresponding change in revenue from kVAh tariff observed. The revenue neutral point
(where revenue as per current tariff as calculated earlier and revenue at kVAh tariff is equal) is then
determined to be the ‘Revenue Neutral CF’. This Revenue Neutral CF is subsequently used as the
conversion factor for assessing the impact on the individual consumers of that category. This
exercise is carried out for all the different consumer categories.
Tariff Categories
1.20. In the billing system of PSPCL, the billing details of the consumer are stored as per their respective
tariff codes. The codes of the billing system and for the various categories are given as below:

1.21.For the purpose of the study, the analysis has been carried out across all the above tariff categories
for consumers with connected load above 100 kW and for MS category consumers.
Variations in Power Factor across categories
1.22. Although the Hon’ble PSERC’s tariff order for FY 2013-14 only differentiates the LS, Railways,
NRS, Domestic and MS category consumers on the basis of tariff, we have carried out this study for
even the sub-categories within the LS category. The reason for doing this is the presence of huge
variations in the Power Factor across categories. The review of Power Factors for all consumers in
all the above categories for FY 2012-13 have been captured below.

Seasonality of Power Factor
1.24.Apart from variations within a category across consumers, the Power Factor also varies significantly
on the account of seasons.
1.25.It was observed that the revenue neutral conversion factor (or power factor) does not remain constant
throughout the year and as such varies as per the load pattern from month to month.

Findings of the study
1.27.Based on the approach to attaining revenue neutrality as discussed in Point 1.19 and the
consideration of the above factors, the exercise for estimating the Revenue Neutral CF aggregated
for FY 2012-13 for all the consumer categories in question independently, has been carried out.
Additionally, the Revenue Neutral CF for each month for each category has also been computed in
order to capture the variations in monthly impact owing to the seasonal variations in energy
consumption and load patterns. The category-wise results based on the data for the entire of FY
2012-13, have been discussed below. The summary of the monthly impact and the overall profile of
the individual categories have however been given in the Annexure.

Conclusion
1.28.
After considering the impact on PSPCL as well as the various consumers due to the shift from
kWh billing to kVAh based on various tariff conversion factors, the following conversion factors
have been determined for the individual consumer categories in order to maintain a revenue neutral
situation. It is therefore prayed in front of the Hon’ble PSERC that the following tariff conversion
factors be used for billing on kVAh basis.
