or exported energy is billed or credited or carried over on the basis of the retail tariﬀ . This process shall

continue until the end of the settlement period. At the end of the settlement period, credit i.e the net

units of surplus generation available if any shall get lapsed;

6.3 In case the Eligible Consumer is within the ambit of Time of Day (ToD) tariﬀ , the electricity consumption

in any time slot, i.e. peak hours, oﬀ -peak hours, etc., shall be ﬁ rst compensated with the quantum of

electricity injected in the same time slot; any excess injection over and above the consumption in any

other time slot in a Billing Cycle shall be accounted as if the excess injection had occurred during

oﬀ -peak hours;

6.4 Net billing or Net feed-in:

6.5 The monetary value of the imported energy is debited based on the applicable retail tariﬀ ; The monetary

value of the exported energy is credited based on the feed-in tariﬀ determined by the Commission. The

monetary value of the exported energy is deducted from the monetary value of imported energy to arrive

Oct. 20, 2021]

TAMIL NADU GOVERNMENT GAZETTE

171

at the net amount to be billed. If the cumulative credit amount exceeds the debit amount during any

billing cycle, the net credit is carried over to the next billing cycle. At the end of a 12-month settlement

period, the consumer has the option to receive payment of the net credit balance (if any) or have such

credit balance carried-over to the next settlement period;

6.6 Gross-metering:

6.7

Gross metering is permitted for eligible consumer or generator who opt to sell all generated solar energy

to the distribution licensee. An eligible consumer or generator under the gross metering scheme shall

inject the entire power generated from the GISS station to the distribution system of the distribution

licensee to the nearest HT network of same voltage. The exported solar energy is credited at the feed

in tariﬀ determined by the Commission. The amount is credited in the Generator/consumers electricity bill

for every billing cycle or paid to the solar generator/ GISS station owner if the generator/ station owner

is not a consumer;

6.8

Net work charges are leviable for the total energy generated in Net metering and Net billing or Net feed-

in mechanisms. Net work charges are not applicable to Gross metering mechanism;

6.9 General:

(i)

Any other charges determined by the Commission from time to time shall be leviable to the eligible

consumer/prosumer/generator;

6.10 For the purpose of billing the import, export and net energy, the units and other allied parameters

recorded in the respective import and export and net register of the consumer bidirectional meter shall be

reckoned respectively. The maximum demand recorded in the gross generation meter or inverter, as the

case may be, shall not exceed the sanctioned/ contracted plant capacity of GISS in any billing cycle. If

the demand exceeds the sanctioned limit in any billing cycle, the quantum of exported units recorded in

the bi-directional meter during the respective demand integration period (DIP) in case of gross metering

and respective billing cycle in case of net-metering and net billing, proportionate to the portion of demand

that exceeded over the sanctioned limit, shall be treated as inadvertent injection in to the grid and shall

not be eligible for payment by the Licensee;
