Electricity North West
Licensed distribution network operator in NW England
Area: 12,500 square kilometres
Key network asset statistics;• 13,000 km of overhead lines• 44,000 km of underground
cables • 84,000 items of switchgear• 34,000 transformers
Customer base: 2.3 million
Deliver over 25 TWh pa
What is Capacity to Customers?
Technical Innovation
Current Demand
Latent Capacity
Total available network capacity
Apply remote control equipment to the HV circuit and close the normal open point
Enhance network management software
This effectively doubles the available capacity of the circuit negating the need for traditional reinforcement
New Commercial Contracts
To retain customers’ security of supply we will utilise innovative demand side response contracts
These contracts will allow ENWL to control the consumption of customers on a circuit at the time of fault
Utilised Capacity
Capacity to Customers
Total available network capacity
Combining proven technology and new commercial contracts
Allows ENWL to release significant network capacity back to customers
Facilitating connection of new demand and generation without reinforcement

Monitoring the effect of the trial
We have partnered with the University of Manchester and the University of Strathclyde
Strathclyde Scope of Works includes;• Power System Modelling & Simulation – To inform the hypothesis that ‘C2C
method will reduce like-for-like power losses initially but this benefit will gradually be eroded as newly released capacity is utilised’ and ‘C2C method will improve power quality’
Manchester Scope of Works includes;• Carbon Impact Assessment – To inform the hypothesis ‘C2C method will
facilitate a reduction in the carbon costs of network reinforcement’
• Economic Benefit Analysis - To inform the hypothesis that ‘C2C will facilitate lower reinforcement costs for customers for the connection of a new loads and generation’ and to also consider the wider impacts on both customer and network operator’s business models.
