  • Sanctioned load/contracted load
    Sanctioned load is the maximum demand which is to be supplied by the discom to the consumer as indicated in the agreement between them. It is denoted in kW, kVA, or HP.
  • Distribution transformer (DT) capacity
    A distribution transformer is a step-down transformer which is used for electric power distribution. DT capacity is the maximum load that can be put on a transformer within voltage limits by the electricity-generating consumers.
  • Surplus generation
    It is the difference in electric power exported from the RTS plant and imported from the grid. It is denoted in kW, kVA, or HP.
  • Cap on export with respect to consumption
    It is the limitation put on the export of electricity to the transformer with respect to the consumer’s total consumption.
  • Billing period
    The time period for which regular electricity bills are prepared for the consumers by the discom.
  • Settlement period
    The time period within which consumers should be compensated for the surplus energy injected into the grid if it has not yet been settled in the billing period.
  • Range allowed
    This is the approved minimum and maximum capacity of the rooftop solar system which can be installed by an eligible consumer.
  • Average power purchase cost (APPC) rate
    The weighted average pooled price at which the discom purchased electricity from its energy suppliers, except those based on renewable sources, including its self-electricity generation cost in the previous year.
  • Feed-in tariff (FiT)
    The payment made in proportion to the power generated to consumers who generated electricity from renewable sources and provided it to the grid.
  • Group-net metering
    An arrangement whereby the surplus energy which is generated from a renewable source and fed into the grid through net metering is adjusted within the same discom’s area of supply in more than one electricity service connection(s) of the same consumer.
  • Virtual-net metering
    An arrangement in which the entire energy which is generated from a renewable source is exported to the grid through a net meter or gross meter, and the exported energy is adjusted within the same discom’s area of supply in more than one electricity service connection(s) of the participating consumer.
