How could we use this relationship in a smart way to benefit customers? This fundamental relationship is at the heart of CLASS But how will it change over time as customers adopt new devices?

Back to school for a moment . . .

How does it work The cost £ to make your cup of tea is always the same! What problems could we solve ?

“A problem shared is a problem halved . . .”

CLASS proposes to harness thousands

  • f tiny changes at just the right time

2% decrease in demand at peak times Lower network costs Faster connections 2% decrease in demand Lower balancing costs Reduced carbon 2% increase in demand Lower energy costs

The CLASS trials

Technique Objective

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

Harnessing world class technology in a innovative solution

Advanced Network Management System Smart voltage control relay in major substations linked to control centre Links DNO control centre to National Grid control centre. Advanced dashboard measures real time availability. Allows demand and voltage control call off when required 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
