The Export Tariff rewards you only for the electricity which you feed back into the grid.
For people with battery storage systems the ET also allows you to buy electricity at a lower rate in the night-time to charge your batteries and use the electricity the next day. This is particularly interesting in the winter months when solar gain is lower.
There are several different tailor made tariff’s you can choose from. It is worth comparing the offers from different electricity providers to get the best available tariff. Here are a list of companies who offer tariffs. You can only receive the Export Tariff if you have a SMART meter installed.
