Conditions applicable to HT installations and billing

HIGH TENSION SUPPLY
Applicable to Bulk Power Supply of Voltages of 11KV (including 2.3/4.6 KV) and above at Standard High Voltage or Extra High Voltages when the Contract Demand is 50 KW / 67 HP and above.

1. Billing Demand

A) The billing demand shall, during unrestricted period, be the maximum demand recorded during the month or 75% of the CD, whichever is higher.

B) When the Licensee has imposed demand cut of 25% or less, conditions stipulated in (A) shall apply.

C) When the demand cut is in excess of 25%, the billing demand shall be the maximum demand recorded or 75% of the restricted demand, whichever is higher.

D) If at any time the maximum demand recorded exceeds the CD or the demand entitlement or opted demand entitlement during the period of restrictions, if any, the consumer shall pay for the quantum of excess demand at one and half times the normal rate per KVA per month as deterrent charges as per Section No. 126(6) of Electricity Act 2003. If the time of day Meter is fixed and is operational, there will be no penalty for over drawal upto 1.2 times the Contract Demand during off peak hours provided the Licensee has declared the peak and off peak periods. For over drawal during peak periods and over drawal above 1.2 times the Contract Demand during off peak hours, the penalty shall be one and half times the normal rate.

E) During the periods of disconnection, the billing demand shall be 75% of CD or 75% of the demand entitlement that would have been applicable, had the installation been in service whichever is less. This provision is applicable only if the installation is under disconnection for the entire billing month.

F) During the period of energy cut, the consumer may get his demand entitlement lowered, but not below the percentage of energy entitlement, (E.g., In case the energy entitlement is 40% and the demand entitlement is 80%, the re-fixation of demand entitlement cannot be lower than 40% of the CD). The benefit of lower demand entitlement will be given to effect from the meter reading date of the same month, if the option is exercised on or before 15th of the month. If the option is exercised on or after 16th of the month, the benefit will be given effect to from the next meter reading date. The consumer shall register such option by paying processing fee of Rs.100/- at the Jurisdictional sub-division office.

(i) The billing demand in such cases shall be the “Revised (Opted) Demand Entitlement” or the recorded demand, whichever is higher. Such option for reduction of demand entitlement is allowed only once during the entire span of that particular “Energy Cut Period”. However, the consumer can opt for a higher demand entitlement up to the level permissible under the demand cut notification and the benefit will be given effect to from the next meter reading date. Once the consumer opts for enhancement of demand, which has been reduced under Clause (F), no further revision is permitted during that particular energy cut period.

(ii) The opted reduced demand entitlement will automatically cease to be effective when the energy cut is revised. However the facility for reduction and enhancement can be exercised afresh by the consumer as indicated in the previous paras.

G) For the purpose of billing, the billing demand of 0.5 KVA and above will be rounded off to the next higher KVA and billing demand of less than 0.5 KVA should be ignored. 

2. Power factor (PF) 

It shall be the responsibility of HT consumer to determine the capacity of PF correction apparatus and maintain an average PF of not less than 0.90. 

(i) The specified P.F. is 0.90. If the power factor goes below 0.90 Lag, a surcharge of 3 Paise per unit consumed will be levied for every reduction of P.F. by 0.01 below 0.90 Lag. 

(ii) The power factor when computed as the ratio of KWh / KVAh will be determined up to 3 decimals (ignoring figures in the other decimal places) and then rounded off to the nearest second decimal as illustrated below:

(a) 0.8949 to be rounded off to 0.89
(b) 0.8951 to be rounded off to 0.90

In respect of Electronic Tri-Vector meters, the recorded average PF over the billing period shall be considered for billing purposes. If the same is not available, the ratio of KWh to KVAh consumed in the billing month shall be taken.

3. Rebate for supply at high voltage:

If the consumer is availing power at voltage higher than 13.2 KV, he will be entitled to a rebate as indicated below:
Supply Voltage:       Rebate
A) 33/66 KV              1 Paise/unit of energy consumed 
B) 110 KV                 2 Paise/unit of energy consumed
C) 220 KV                 3 Paise/unit of energy consumed

The above rebate will be allowed in respect of all the above voltage class installations including the existing installations and also for installations converted from 13.2 KV and below to 33 KV and above and also for installations converted from 33/66 KV to 110/220 KV from the next meter reading date after conversion / service / date of notification of this Tariff order as the case may be. The above rebate is applicable only on the consumption of normal energy consumed by the consumer including the consumption under TOD Tariff and is not applicable on any other energy allotted and consumed, if any, viz.,

i) Wheeled Energy
ii) Any energy including the special energy allotted extra over and above normal entitlement.
iii) Energy drawal under Rs.3.80 special incentive scheme.

The above rebate is not applicable for Railway Traction.

4. In respect of Residential Quarters/ Colonies availing Bulk power supply by tapping the main HT supply, the energy consumed by such Colony loads metered at single point shall be billed under HT-4 tariff schedule. No reduction in demand recorded in the main HT meter will be allowed.

5. Energy supplied may be utilised for all purposes associated with the working of the installations such as Office, Stores, Canteens, Yard Lighting, Water Supply and Advertisements within the premises.

6. Energy can also be used for construction, modification and expansion purposes within the premises.

7. Power supply under HT-4 tariff schedule may be used for Commercial and other purposes inside the colony for installations such as Canteen, Club, Shop, Auditorium etc., provided this load is less than 10% of the CD.

8. In respect of Residential Apartments availing HT Power supply under HT-4 tariff schedule, the supply availed for Commercial and other purpose like Shops, Hotels, etc., will be billed under appropriate tariff schedule (Only Energy charges) duly deducting such consumption in the main HT supply bill. No reduction in the recorded demand of the main HT meter is allowed. Common areas shall be billed at Tariff applicable to predominant consumer category. 

9. Seasonal Industries

(a) The industries who intend to utilise seasonal industry benefit shall conform to the conditionalities under para no. 25 of general terms and conditions of tariff (applicable to both HT & LT).
(b) The industries that intend to avail this benefit should have Electronic Tri-Vector Meter fitted to the installation.
(c) Monthly charges during the working season shall be the demand charges on 75% of the contract demand or the recorded maximum demand during the month, whichever is higher, plus the energy charges
(d) Monthly charges during the off season shall be demand charges on the maximum demand recorded during the month or 50% of the CD which ever is higher plus the energy charges.
