What we do

We manage the changing patterns of electricity demand and supply

Previously, large coal, gas and nuclear power plants were the main source of electricity, dominating Great Britain’s electricity generation market.

Electricity flowed from generation plants through the transmission network, to the distribution network and on to wherever it was needed.

The coal and gas plants were easily controllable and could be turned up or down in response to how much electricity was needed across the whole of Great Britain.

However, new forms of generation such as wind and solar are replacing these traditional plants.

We're transforming the system

So, the flow of electricity is getting more complex, but at National Grid ESO we are continuously developing the system to ensure we can meet the nation’s needs.

Working hand in hand with the energy industry, we’re continually finding ways to innovate, invest and adapt the electricity system to keep electricity flowing reliably to homes and businesses across Great Britain.
