Social Energy has the best offer for prosumers under the Smart Export Guarantee (SEG), according to the Solar Trade Association’s (STA) SEG League Table.
With a rate of 5.6p/kWh for its fixed-rate SEG, Social Energy’s SEG Tariff was ranked above Octopus Energy’s Outgoing Fixed and E.ON Energy’s Fix & Export Exclusive tariffs – both 5.5p/kWh. Both Bulb Energy and Octopus Energy are also offering flexible SEGs, pegged to the half-hourly wholesale rate.
The SEG came into force from 1 January, obligating suppliers to offer a tariff and make payment to small-scale low-carbon generators for electricity exported to the National Grid. It serves as an opportunity to anyone who has installed solar PV, wind, hydro or anaerobic digestion up to a capacity of 5MW, or micro combined heat and power up to 50kW. Exporters must also be able to demonstrate that their generating equipment, along with its installation, has been certified to MCS or an equivalent standard.
Medium to large electricity supply companies – with more than 150,000 electricity consumers – are required to offer an SEG, while it is voluntary for smaller suppliers.
