  • System Operating Plan (SOP)


    As part of our daily planning processes within the ESO control room, the control room strategy team produces a System Operating Plan (SOP) at key demand peaks or troughs throughout the day, at what we...

  • Daily Balancing Services Use of System (BSUoS) Cost Report


    The BSUoS charge recovers the cost of day-to-day operation of the transmission system. Generators and suppliers are liable for these charges, which are calculated daily as a flat tariff for all users....
