Capacity to Customers
Capacity to Customers
Technical innovation
Utilised capacity
Current demand
New commercial contracts
Latent capacity
Combines proven technology and new commercial contracts
Remote control equipment on HV circuit and close the NOP
Innovative demand side response contracts
Releases significant network capacity
Enhanced network management software
Allow us to control customer’s consumption on a circuit at the time of fault
Facilitates connection of new demand and generation without reinforcement
Effectively doubles the available capacity of the circuit

Capacity to Customers and beyond
When is C2C cost ... or when should effective ...? we reinforce?
Working with University of Manchester to develop economic methodology

Customer Load Active System Services
CLASS is seeking to demonstrate that electricity demand can be managed by controlling voltage…without any discernible impacts on customers
Reduces demand at time of system peak
Demand reduction
System balancing support
Provides a demand reduction capability to support system balancing
Voltage control
Mitigates excessive voltages when generation is high and demand is low 8
Smart Street
New controllable switching devices stabilise voltage Allows us to lower voltage levels Enables networks and appliances to work in harmony
Low cost Quick fit Minimal disruption Low carbon Low loss Invisible to customers Faster connection of low carbon technologies 9
How, when and where to manage LV voltage
Analysis shows much of LV network can accommodate PV Challenge for PV is voltage
‘Connect and manage’ approach developed to avoid connection delays Investigating customers’ perceptions of voltage and if standards are appropriate 10
Fault Level Active Response (FLARE)
FLARE is the first UK demonstration of an active fault level management solution that avoids traditional network reinforcement
Faster LCT adoption Less disruption Lower bills 11
Summary
• Increasingly uncertain and variable capacity requirements • Need to respond more quickly
• Beyond predictable demand growth • Developing solutions to optimise network • Intelligence to understand when to deploy them
