The Tamil Nadu Electricity Board (TNEB) has issued detailed working instructions to its distribution circles all over the State for calculating the revised electricity charges, based on the new tariff, for different categories of consumers.
This follows the tariff order issued by the Tamil Nadu Electricity Regulatory Commission (TNERC).
The Board's instructions, through a circular of August 6, spell out the process of calculating electricity charges according to the revised rates.
Regarding high tension (HT) connections, the TNEB took special readings on August 1 (the day on which the new tariff took effect).
Though no special readings have been proposed for low tension consumers, the Board has worked out a formula to be followed by assessors for calculating the electricity charges. The formula is as follows:
Time gap between the date of meter reading and date of the new tariff coming into force (August 1) will have to be multiplied by the number of units consumed as recorded at the time of meter reading. This has to be divided by the number of days that have gone by since the last meter reading.
The eventual resultant number shows the number of units consumed for calculating energy charges under the new tariff.
Suppose a consumer has consumed 1,220 units from June 11 to August 10 (61 days). In this case, the number of units consumed since August 1 will be 200 units. By applying the latest rate of Rs.4.05 per unit for those consuming over 601 units in two months, the proportionate amount will be Rs.810. The remaining 1,020 units will be calculated as per old rates and this will be Rs.2,391. The consumer has to pay Rs.3,201.
The circular states that the Section Officers are required to exhibit the revised tariff rates in the notice boards in their offices and collection centres and also affix rubber stamps on the meter cards indicating the new tariff rates.
