Power losses are an inevitable consequence of generating, transmitting and distributing electricity to consumers. One of the ways of achieving efficiency in transmission is to minimise the network losses.
In general, there are two main components of losses in a transmission system: technical losses and non-technical losses. Technical losses are energy lost as heat from power flows though electrical equipment such as cables, overhead lines, and transformers; while non-technical losses are caused by inaccurate metering, billing and energy theft.
Our losses strategy document presents our approach to minimise the level of transmission losses and the associated Scope 3 indirect carbon emissions on our transmission system in order to support our sustainability ambitions.
