The importance of reducing electrical losses on distribution networks is growing. As electricity usage increases, the control of losses to an economic level will become a key feature of network operation. It has only been in the RIIO-ED1 period that Distribution Network Operators (DNOs) have started to publicly document a Losses Strategy.
The energy lost in distribution creates a financial cost which is fronted by the customer. DNO’s are obliged, as part of their license, to reduce losses on their networks as far as reasonably practicable. Reducing the energy lost will reduce carbon emissions, which impacts climate change.
Reducing losses effectively increases the network capacity. This is crucial with energy consumption likely to increase sharply in the near future, as a result of The Carbon Plan and the uptake of new technologies such as electric vehicles and heat pumps. By reducing losses wherever possible, it could reduce the need for costly network reinforcement projects.
National Grid Electricity Distribution (NGED) supply three phase LV Service cables and a three phase cut-out to all new builds and service alterations, but it is entirely the Developer or Building owner’s choice to make use of the three phase supply. By utilising the three phase supply the Developer/Building owner will reduce the losses to the estate or building. This is due to the fact that by using three phase for the fast EV charger, the building owner can theoretically charge their Battery Electric Vehicle up to three times faster than when compared to a single phase fast EV charger.
