Connecting the North West

5 million

2.4 million 23.5 terawatt £12.3 billion assets


UK energy challenges

+ 2014 1/3 gas 1/3 electricity 1/3 oil

2020 2050 34% CO2 reduction 80% CO2 reduction 40% from wind / PV Significant and new nuclear increase in 5% transport 120,000 electricity demand electric vehicles 26 million smart meters fitted

RIIO-ED1 Traditional reinforcement unaffordable 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 3

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


• 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





• Maximising use of existing assets • Offering choice to customers • Leverage learning from other projects and DNOs

• Lower energy bills • More reliable supply • Reinforcement savings
