DG represents the
most immediate
challenge
Uncertainty in future demand and generation  Difficult to predict demand
 More pressure to meet customers’ needs at minimum cost

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

we reinforce?
Working with University of Manchester to

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

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

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
