The way customers use energy is changing….
…. . many customers will increasingly make their own,
….. and many will use it in different ways to ….
….. heat their homes ….. and move around

The way customers use energy is changing ….
…. but what they want from their network company is very similar to today

Electric Vehicle Charging – disruptive change?
Increasing battery capacity
Nominal 13A
• More obvious issues with wiring capacity and connectors
• Less obvious issues with local grid constraints (designed for typically 1.5kW to 2.5kW per household)

Modelled Impact of Charging Electric Vehicles
• Indicative test results of Household demand/ EV charging in a small/medium sized city.
• Demonstrating the effects of people returning home in the evening and plugging in their vehicles.
• Graph shows 10% to 50% uptake of households with EVs.
• Based on 5-7% of miles travelled by Electric Vehicles by 2020 .

A new energy system requires more intelligent networks
Invest in copperDescriptionReinforce the networks
ConclusionRisk of unnecessary costs
Invest in intelligenceDescriptionInvest in energy network intelligence and flexibility:
Conclusion Increased flexibility Future-proof solution Efficient investment Support sustainability
…and how we get the electricity to them is even smarter!

Key goals ……..
1. Confirm impact on the Local Grid
2. Determine the most cost effective way of providing connections
3. Better understand customer uptake profile and pattern of use
4. Evaluate regulatory models for funding infrastructure
