If you receive a ‘feed-in-tariff’ you do not need the smart export guarantee.
The Smart Export Guarantee is for installations which have been registered since the ‘Feed-in tariff’ ended.
This allows you to be paid for the excess electricity which you export to the grid.
All of the main Electricity suppliers offer SEG’s
Some are fixed price, some are variable.
Variable tariffs vary depending on how valuable the export is to the grid at different times.
The price you are paid will not fall below zero at any point.
Variable tariffs are offered to encourage customers to shift their electricity usage away from peak times and to encourage export when the electricity system needs more power.
Export rates may change 1/2 hourly and a smart meter records the amount and time of your export, or they could be day, night or weekend rates.
