EXPORT
The Smart Export Guarantee (SEG) is the framework under which participating electricity suppliers pay eligible small-scale generators for electricity exported to the grid.

Who can be eligible?
Ofgem lists solar PV among the eligible technologies. Eligible installations must be in Great Britain and, for solar PV and most other listed technologies, have total installed capacity no greater than 5 MW.
There is no single SEG rate
SEG licensees set their own tariff rate, contract length and other terms, subject to the scheme rules. Ofgem states that the tariff rate must be above zero, so homeowners and businesses should compare current offers rather than assuming a universal export price.
