• Electricity injected less electricity consumed should be considered as the banked electricity for the next billing cycle within the settlement period.
• Electricity consumed less electricity injected into the grid shall be treated as net electricity consumption and should be billed as per applicable tariff of the respective consumer category after taking into account any electricity credit balance from the previous billing period.
• In case of time of day tariff, electricity consumption in any time block should be first compensated with the electricity injected in the same time block. Any excess injection, over and above the consumption, in any other time block in a billing cycle should be accounted as if the excess injection occurred during non-peak hours.
