How does electricity move around?

As National Energy System Operator (NESO), we're at the heart of Great Britain's electricity system. However, moving electricity around requires a complex network of partners working in tandem.

We use infrastructure owned by transmission companies to pass high voltage electricity onto Distribution Network Operators (DNOs). The DNOs then use their own network of overhead lines and underground cables to take the electricity from the grid, and deliver it to homes, schools, hospitals, and businesses.

Interconnectors are cables that allow electricity sharing between Great Britain and other countries. Aggregators help people use electricity at the best times – for example, working with supermarkets to adjust their freezers to come on and off at different times rather than taking a steady supply.

We manage and control this delicate process every second. Matching the energy load balances the demand in real time and ensures a reliable energy flow. Find out more on electricity explained.
