The calculation of the deemed export is based on the following factors and has been set by the Commission for Regulation of Utilities (CRU).

The following formula determines the Deemed Export Quantity:

Deemed Export Quantity= MEC x Capacity Factor x Export Factor x Provision Interval

MEC – This will come from the NC6 form which the customer is required to submit to ESBN.

Capacity Factor – This is based on a calculation from the CRU and is set at 9.7%

Export Factor – This is based on a calculation from the CRU and is set at 35%

Provisional interval – This is a calculation used for solar installations that takes account of how Microgeneration works in practice during the day and from season to season.

It’s important to note that you will need a smart meter to be eligible for actual metered exports.
