They ensure the reliable and efficient flow of electricity from generators to consumers, balancing supply and demand in real-time, 24/7. Key responsibilities include managing system frequency, voltage, and stability, procuring ancillary services, providing system data and insights, and facilitating the connection of new generation and demand. National Grid ESO plays a pivotal role in Great Britain's transition to a decarbonised energy future, integrating increasing amounts of renewable energy sources while maintaining security of supply.
