  2. Customer Load Active System Services Maximise use of existing assets Offer new Innovative services and solutions Delivering choice for to real value to the future problems customers Generate Proven value for technology CLASS customers deployable now today 2 Customer Load Active System Services - Expert Panel Presentation

  3. Back to school for a moment . . . This fundamental relationship is at the heart of CLASS But how will it change over time as customers adopt new devices? How could we use this relationship in a smart way to benefit customers? 3 Customer Load Active System Services - Expert Panel Presentation

  4. How does it work 00:03:00 00:00:08 00:00:08 2% 2% The cost £ to make your cup of tea is always the same! 20,000 homes in a town “A problem shared 200,000 homes is a problem halved in a city . . .” 26 million across the UK What problems could we solve ? 4

  5. CLASS proposes to harness thousands of tiny changes at just the right time 2% decrease in demand 2% decrease in demand 2% increase in demand at peak times Lower balancing costs Lower energy costs Lower network costs Reduced carbon Faster connections Today Tomorrow Future High peak demand Response and reserve Wind following 5

  6. The CLASS trials Objective Technique Establish voltage/demand Load modelling Raise & lower tap position relationship Demand response for peak Demand response Lower tap position reduction Primary response to reduce demand when frequency falls on the Switch out transformer transmission network Frequency response Secondary response to reduce demand after primary response Lower tap position above Absorb high voltages that occur on Reactive power Stagger tap position the transmission network 6

  8. The technology Smart voltage control relay in major substations linked to control centre Allows voltage to be adjusted to drive demand changes. Automatically stabilises network frequency. Keeps voltages at safe levels on transmission and distribution networks with high amount of DG Advanced Network Management System Links DNO control centre to National Grid control centre. Advanced dashboard measures real time availability. Allows demand and voltage control call off when required Harnessing world class technology in a innovative solution 8
