(9) For the energy to be billed or settled as per the provisions under sub-regulation 4, 5 and 8, the distribution licensee shall raise bills or carry out necessary adjustment, as the case may be, in the following manner and at the following rates:-
(i) Energy Charges:-
(a) The quantum of energy for which the energy charges are to be recovered by the distribution licensee for a billing period as per sub-regulation (4) shall be billed to the consumer at the rate(s) of energy charges, applicable as per the applicable tariff:
Provided that where different rates of energy charges are applicable for different times of the day (normal, peak and night hours etc.) as per the applicable tariff, the energy accounting shall be done separately for each time of day as per sub-regulation (8) and energy charges shall be recovered at respective rates for respective quantums of chargeable net energy.
1 [ (b) The distribution licensee shall settle the quantum of energy to be settled for anytime of the day at the end of the settlement period in accordance with subregulation (5) and (8), in the following manner, namely:—
(i) in cases where the Letter of Approval is issued as per the subregulation (3)of Regulation 7, also duly taking into account the 3rd proviso to the same, on or before 15.11.2018, the amount payable to the consumers for such energy shall be worked out at a fixed rate of Rs. 5.00 per kWh of the energy to be settled in case of consumers covered under single part tariff and at a fixed rate of Rs. 4.50 per kVAh in case of consumers covered under two parts tariff:
Provided that if the amount of subsidy or grant or both, available to eligible consumer under the relevant scheme(s) of the Government(s) (State or Centre) or their agencies, exceeds 50% of the normative capital cost of the rooftop solar PV system, the aforesaid rates of Rs. 5.00 per kWh and Rs.4.50 per kVAh, as applicable, shall be reduced by 50% and such eligible consumer shall, for such purposes, be deemed to have availed the total (maximum) subsidy or grant, or both, as available under such scheme(s) irrespective of the amount actually availed by him;

“ (b) For the quantum of energy to be settled for any time of the day at the end of the settlement period in accordance with sub-regulation 5 and 8, the distribution licensee shall pay, byway of adjustment of amount in future electricity bills, at a fixed rate of Rs. 5.00 per kWh of the energy to be settled in case of consumer covered under single part tariff and at a fixed rate Rs. 4.50 per kVAh in case of consumer covered under two parts tariff:
Provided that the if the amount of subsidy or grant or both, available to eligible consumer from Government agencies exceeds 50% of the capital cost of the rooftop solar PV system, the aforesaid rates of Rs.
5.00 per kWh and Rs. 4.50 per kVAh, as applicable, shall be reduced by 50%;
Provided further that the Commission may, by order, revise the aforesaid rates of Rs. 5.00 per kWh and Rs. 4.50 per kVAh, as and when it finds it expedient to do so;
Provided further that in the event of revision of such rates as per the second proviso to this subregulation, such revised rates shall be applicable only for such cases in which letter of approval is yet to be issued in accordance with the provisions contained in the regulation 7.” 12 Compendium of HPERC Regulations, March 2021

Provided further that average demand for any time of day block of the billing period shall also be worked out on the basis of the net import, if any, of energy by the eligible consumer during the billing period (but without adjustment of electricity credits) from the distribution system in respect of respective times of the day over the billing period.
1 [(iii) Other charges:—
(a) Any other charges as per the applicable tariff shall be charged to the consumer at par with other consumers of similar category who are not generating any Rooftop Solar PV power under this scheme.
