As the Electricity System Operator (ESO) for Great Britain, we sit at the heart of the nation’s energy system, running electricity networks safely and efficiently, minute by minute, hour by hour, 365 days a year. It’s our job to make sure there is enough electricity when people need it – we are the people who make sure the lights stay on, the kettle boils and your phone charger works, whether there’s demand from one person or one million.
