Power Charges – Methodology for Calculation

Objective:	Transparent billing procedures for all utilities.
Utilities Details:
	a) Electricity
	b) Air-conditioning

a) Electricity

The electricity charges consists of two major components namely

- Fixed Demand (KVA) Charges

- Variable energy (Kwh) Charges

Fixed Charges:

Rate:

Fixed demand will be charged at the prevailing Tamilnadu Electricity Boards (TNEB) rate of Rs.300 / KVA / Month.

Apportion Basis:

As detailed in Clause-2 of base building specifications, each occupant is allotted KVA Demand at 1.25 KVA per 100 sft of chargeable area.

The monthly “Sanctioned Demand Charges” as billed by TNEB will apportioned on the bases of allotted KVA demand as detailed above in clause -2 of base building specifications.

Sample Calculations:

Occupant-A Chargeable area	: A sft.
Occupant-B Chargeable area	: B sft.
Occupant-C Chargeable area	: C sft.
Total Chargeable area	: A+B+C sft.
Monthly Demand Charges	: Rs. X as billed by TNEB
Monthly Interest on development	: Rs. Y
Deposit made to TNEB
Total Demand Charges	:Rs. (X + Y)
Demand Charges of Occupant A	: Rs. (X+Y)* A sft. / (A+B+C) sft
Demand Charges of Occupant B	: Rs. (X+Y)* B sft. / (A+B+C) sft
Demand Charges of Occupant C	: Rs. (X+Y)* C sft. / (A+B+C) sft
Total Demand Charges collected	: Rs. (X+Y)

Variable energy (Kwh) Charges

Rate:

Basis of calculation for energy charges

Total TNEB Bill (Energy + Demand Charges)	Rs.Z1
Total Demand Charges	Rs.X
Cost of Diesel + Lub Oil for standby DG’s	Rs.Z2
Net Energy (Kwh) Charges	Rs.(Z1+Z2-X)

Basis of calculation for energy (Kwh)

Total TNEB billed Energy (Kwh Units)	: EB KWh
Occupant A Energy (sum of all occupant A energy meters)	: a Kwh
Occupant B Energy (sum of all occupant B energy meters)	: b Kwh
Occupant C Energy (sum of all occupant C energy meters)	: c Kwh
Chiller Energy (sum of all chiller energy meters)	: d Kwh

Total Energy (except for common area)	: (a+b+c+d) Kwh
Total Energy except for common area including 4% Transmission losses	: (a+b+c+d)* 1.04 Kwh.

Common Area Energy	(EB KWh - (a+b+c+d)* 1.04 Kwh) : e Kwh.
Occupant A energy bill	: Rs. (Z1+Z2-X)* a KWh/ (a+b+c+d+e)*1.04 KWh
Occupant B energy bill	: Rs. (Z1+Z2-X)* b KWh/ (a+b+c+d+e)*1.04KWh
Occupant C energy bill	: Rs. (Z1+Z2-X)* c KWh/ (a+b+c+d+e) *1.04KWh
Common Area energy bill to be paid by developer from O&M charges	: Rs. (Z1+Z2-X)* e KWh/ (a+b+c+d+e)* 1.04 KWh

AC Btu charges calculations

Total Btu Charges	: Rs. (ZI+Z2 - X)* d KWh/ (a+b+c+d-1 e) KWh
Btu Generated by Chillers	: BT Btu
Unit Btu rate (xx Rs. / Btu)	: {Rs. (Z1+Z2 -X)* d KWh/ (a+b+c+d+e) KWh}/ BT Btu,:
Occupant A Btu	: B1 Btu
Occupant B Btu	: B2 Btu
Occupant C Btu	: B3 Btu
Common Area Btu	: {BT-(B1+B2+B3)*1,02} Btu.

Occupant A AC Charges : Rs. xx*B1

Page 23 of 24

Occupant B AC Charges	: Rs. xx*B2
Occupant C AC Charges	: Rs. xx*B3
Common Area AC Charges by developer from O&M charges	: Rs. xx*{BT-(B1+B2+B3)}

Note: The demand and KWh rates are based on prevailing TNEB rates. For billing purpose, the rates prevailing on the date of invoice shall be applicable.
