NEM Excess Energy Calculation

The surplus energy supply to NEM consumers will be determined based on the leading displaced cost of the necessary voltage level supplied at the existing coupling point. Note also that the net electricity billing shall be calculated based on the following criteria:

Net Billing = [Energy Consumed from DL (kWh) x Gazetted Tariff] – [Energy Exported to DL (kWh) x Displaced Cost]

i.e energy consumed shall be multiplied by the subscribed tariff plan and subtracted from the exported energy and multiplied by the displaced cost.

Unexhausted credits shall be rolled over for a maximum of 2 years after which any other credits will be void.
