• RPO will be on the total consumption of electricity, excluding that from hydro sources other than mini hydel projects.

• Electricity generated from rooftop solar PV systems under net metering will qualify to meet solar RPO.

• Obligated entity shall install and maintain a solar generation meter, at its cost, if it counts energy generated from the rooftop solar PV plant to fulfill its RPO obligations.

• Electricity purchased will qualify to meet RPO if the generator does not claim RECs.

• Any generating company ineligible to qualify as captive generating plant as per Indian Electricity Rules, 2005, but having self-consumption will have to meet RPO. 

• Obligations to purchase solar and non-solar energy can be fulfilled only by purchase of solar and non-solar certificates, respectively.
• Obligated entities may fulfill their non-solar RPO obligations through equal number of solar RECs so long as the solar REC price is higher than that of non-solar RECs.

• A renewable energy generator, including an eligible captive generating plant, shall be permitted to retain the certificates for offsetting its RPO in a financial year which is the same as the year of application.

• The renewable energy generator shall not be allowed to retain certificates for offsetting RPO of its group companies as consumers.
