Earlier in June, the Government of Andhra Pradesh released an Order (G.O.Ms.No.27) containing guidelines for making payment for surplus energy injected into the grid as a part of the AP Rooftop Solar Net Metering policy. As per this order, payment shall be considered by the concerned APDISCOMS at pooled cost as decided by APERC for that year and this payment will be made effective for 7 years from the date of establishment of such a plant. Our blogpost for more details on this order can be accessed here.
Following this, guidelines for implementation of this net metering policy have recently been released on the APTRANSCO website. Given below are some of the important points from this document.
- A single bi-directional BIS/ISI certified meter is to be installed for export and import
- For PV systems up to: 10 kW – Class 1 accuracy meters, Above 10 kW – 0.5 class accuracy, HT systems (56 kW and above) – 0.2 class accuracy meters are to be installed
- MNRE subsidy, Government of AP subsidy and any other subsidy relevant to solar panel based net metering solution should be front loaded on the consumer cost and the vendor should claim the subsidy component from New and Renewable Energy Development Corporation of Andhra Pradesh (NREDCAP)
- 2 months net bill should be submitted by the vendors to NREDCAP to claim subsidy
- NREDCAP is the nodal agency for release of both MNRE and GoAP subsidy
- Consumer can download the solar rooftop net metering application from from the official websites of APDISCOMS and submit the same to the concerned Divisional Engineer/Operation/APDISCOM
- DISCOMs personnel shall conduct a feasibility analysis of the DTR within 15 working days of the receipt of completed application form
- Approval is granted for installation of SPV system based on the feasibility study
- Consumer should install a SPV system and request DISCOM authorities for inspection within 6 months from receiving approval
- Inspection of equipment, circuitry and meter along with synchronization of the SPV is carried out within 10 working days of receiving the request
Billing and payment:
- In case of net export bill, credit amount will be carried forward to the next month for adjustment against next month import bill. No interest will be payable for this amount carried forward and the net credit available will be refunded twice a year – June and December, deposited in the consumer’s bank account
The original document containing these guidelines can be downloaded here. NREDCAP organised an exhibition on 24th and 25th August on Solar Rooftop PV systems and Net Metering in Hyderabad.
