Distribution Losses

These are similar to transmission losses but are the losses incurred on the DNO’s distribution network whilst transporting the electricity from the grid supply point to the customer’s premises. Again it is expressed as a percentage of the kWhs used & varies from one DNO to another (as each DNO’s network will be slightly different) & will vary dependant upon the customer’s supply voltage. DNO losses typically vary between 3 & 6% which is higher than the transmission losses due to the lower voltages used on the DNO networks.
