Electricity Billing by Apartment Societies

Almost every  state electricity board has increased the tariff from 01 Apr 2013. The increase has been 10% to 20 % on an average. There are also some new categories introduced. One example is that DHBVN has created three categories of bulk customers and charges different rate for three different categories. So how should the societies charge the individual flats for the electricity bill:

There are two methods which can be used to raise the electricity bill for individual flats:

<(A)   Flat Rate Model

<(B)   Variable / Telescopic Rate Model

 

<(A)  Flat Rate Model

 

What societies do in the flat rate model is that calculate  per unit average rate based on the bulk electricity bill received by the society and charges the same to the individual residents. An example is as follows:

State Haryana /DHBVN

Consumption (units)

MD (kVA)

# of flats

consumption per flat (units / flat)

Tariff for units /flat of more than 800 units per flat (Rs /unit)

FSA (Rs / unit)

Fixed Charges (Rs / unit)

409120

1296

400

1023

5.1

0.81

80

Energy Charges (Rs)

FSA (Rs)

Fixed Charges (Rs)

Duty (Rs)

Municipal Tax (Rs)

Total (Rs)

Average Rate (Rs / unit)

2086512

331387

103680

40912

20456

2582947

6.31

Thus for a flat with electricity consumption of 670 unit per month would have electricity bill = Rs 6.31*670 = Rs 4227.70

Pros:

(i)                  It is a very simple method for calculation

Cons:

(i)                  It does not disincentive the high energy users. As some users use more electricity, the average per flat consumption for the society goes up and the society gets subjected to highest slab rate (applicable only for Haryana as of now)

(ii)                There is a weak regulatory case for such flat tariff. Technically, the society should charge an individual based on the state electricity board individual tariff plan.

 

 

 

<(B)   Variable Rate Model

In the variable rate model, an individual flat is charged based on the individual tariff plan for the state electricity board. For example individual tariff plan for DHBVN is as follows:

Category of Consumer

Tariff for 2013-14 (Applicable from 1 Apr 2013)

Energy Charges (Paisa/Unit)

Fixed Charge (per kW of the connected
load) per month

MMC (per kW per month of the connected load)

Domestic LT
Category I: (Total consumption less than 100 units per month)

 upto 40 units per month

298

Nil

Rs. 100 up to 2 kW and Rs. Rs. 60 above 2 kW

41 to 100 units per month

475

Domestic LT
Category II: (Total consumption more than 100 units/month and upto 800 units/month)

0 - 250 units per month

490

Nil

Rs. 100 up to 2 kW and Rs. Rs. 60 above 2 kW

251-500 units per month

560

501 - 800 units per month

598

Domestic LT
Category III: (Total consumption more than 800 units/month)

801 and above units per month (For total consumption of 801 units and above/month, there shall be single tariff & no slab benefit shall be admissible)

                    598
Any consumer  at his own cost may opt for kVAh tariff of 538/kVAh i.e. applicable tariff in kWh multiplied by 0.90 (standard power factor)

Nil

Rs. 100 up to 2 kW and Rs. Rs. 60 above 2 kW

*FSA charges, municipal tax and duty are extra:

Thus the bill for a flat with 670 units and 6 kw connected load would be:

Consumption (units)

Connected Load (kW)

Energy Charges

Fixed Charges

FSA (Rs / unit)

0 - 250 units per month

251-500 units per month

501 - 800 units per month

670

Rs. 100 up to 2 kW and Rs. Rs. 60 above 2 kW

Energy Charges (Rs)

FSA (Rs)

Fixed Charges (Rs)

Duty (Rs)

Total (Rs)

 Pros:

(i)                  It dis-incentivises the high energy users. As some users use more electricity, the average per flat consumption for the society goes up and the society gets subjected to highest slab rate (applicable only for Haryana as of now)

(ii)                This is the correct regulatory method.

(iii)               The load on common area consumption charges goes down

Cons:

(i)                  It has more complex calculations.

(ii)                It does not benefit high energy consumers.
