  • Keeping the Electricity Transmission System in balance

    • National Grid procures Balancing Services in order to balance demand and supply and to ensure the security and quality of electricity supply across the GB Transmission System. In accordance with the Transmission Licence, National Grid is required to establish and publish statements and guidelines on Balancing Services.

      Text:  
      The requirement for reactive 
      power is primarily driven by 
      the interaction of real power 
      flows on the transmission 
      system with the complex 
      impedances of the various 
      elements that make up the 
      network together with the 
      demand at the lower voltage 
      system interfaces.
