The Smart Export Guarantee (SEG) is a UK government-backed scheme that requires electricity suppliers to offer a payment to small-scale low-carbon generators for the excess electricity they export back to the grid.

This includes households with solar panels or wind turbines, for example. Under the SEG, eligible generators can receive payments for the electricity they export, helping to offset their energy bills and potentially earn extra income.

The SEG was introduced in January 2020 to replace the previous Feed-in Tariff scheme, which closed to new applicants in March 2019.
