Ref.No.PR-3/Tariff/ 30457 Dated: 21.09.2005
COMMERCIAL CIRCULAR NO. 9
Sub : Installation of LTMD meters to LT consumers of industrial and commercial category having load of 20 KW and above.
The MERC in its tariff order dated 10th January 2002 has recommended that all consumers particularly LT General Motive Power Consumer category and LT commercial category (opting for MD based tariff) having load more than 20 KW shall be provided with MD based TOD meters. The tariff order also permits the consumer to avail the TOD tariff.
In the matter of connected load i.e. case No. 2 of 2003 the Hon’ble Commission vide its order dated July 14th, 2005 has mentioned as below:
“In case of load drawal exceeding sanctioned load, to be measured through the MD meters (Tri-vector or the Accu-check meters as the situation demands), the consumer shall be billed based on the actual drawn demand and shall be levied penal charges for the unauthorized demand beyond the sanctioned load”.
Hence measurement based assessment should be done for detecting suspected unauthorized extraction of energy beyond the sanctioned load for consumer. This will also be in line with the supply code which has abolished the concept of connected load and developed the code on the basis of sanctioned load only. Instructions have already been issued to the field that no consumer irrespective of the quantum of sanctioned load and whether the energy consumed is being recorded by a LTMD meter or conventional single phase/three phase be penalized for unauthorized connected load on the basis of physical verification. LTMD meters should be installed to all Low Tension consumers having connected load of 20 KW and above even though the consumer has not opted for MD based tariff. Also all new connections of commercial and industrial category irrespective of their load should be released with LTMD meters only. Sanctioned load in terms of kVA Demand of all Low Tension consumers (having sanctioned load of 20 KW or more) should be determined based on the sanctioned load in HP or kW, with 90% power factor, irrespective of whether the consumer has opted for LTMD based tariff or otherwise.
Instructions should be given to record the kVA maximum demand of all such consumers at the time of routine meter reading and in case the kVA Maximum Demand during a particular month happens to be more than the sanctioned load in terms of kVA Demand, penalty should be charged and recovered. Also, Instructions should be given to the respective concerned IT Centers to indicate the sanctioned load on the energy bill of the respective consumers.
All the field officers are instructed to scrupulously follow the above instructions given by the MERC and to ensure that all the consumers having load above 20 KW are installed with MD based TOD meters having facility to record power factor also.
