Transmission and distribution (T&D) losses refer to the losses that occur in the transportation of electricity between the sources of generation and the end customer. Bryt Energy purchases and retires sufficient REGOs each year to cover the electricity lost in the transmission and distribution of your electricity. This is calculated based on the annual loss factor published by the Department for Energy Security and Net Zero, as part of their ‘Fuel Mix Disclosure Data Table’, and is built into our own Fuel Mix Disclosure (FMD).
