The export type is dependent on the meter you have at home. For example, a smart meter has a metered export type, meaning the actual energy generated is measured and payment is made accordingly. All other meters have what’s called a deemed export. This export type assumes that the majority of the electricity generated is being used in the home.

This calculation has been decided by the Commission for Regulation of Utilities (CRU) with government oversight. There is no mechanism to change this amount except for the installation of a smart meter to record actual consumption and therefore the surplus generated. Your energy provider has no role in determining this export value.
