1. An Introduction and Overview
Kevin Hoban & Damien Coyle

2. Agenda Introduction Technology Why Smart Street?
 Agenda for today, this is our first webinar for Smart Street. I will give you an overview of the project concept and benefits this technique will deliver, we’ll have a look at the technology that will be deployed and discuss the Smart Street Trials and what customer engagement activities will take place.

3. Connecting the North West
£8 billion of network assets
4.9 million
2.4 million
25 terawatt

4. Smart Street project overview
£11.5m, 4 year innovation project
£8.4m from LCNF, £1.5m from Kelvatek, £1m from ENW
Project overview
Trials period Sep 2015 – Aug 2017
Started in Jan 2014 and finishes in Dec 2017
Facilitates quicker cheaper connection of domestic LCTs

5. Project partners

6. Smart Street trial areas
6 primary substations
11 HV circuits
Wigton & Egremont
38 distribution substations
163 LV circuits
Wigan & Leigh
Around 62,000 customers
Manchester

7. Smart Street Efficiency Network Customer appliances
Allows networks and appliances to work in harmony delivering
efficiency across the energy supply chain
Low carbon  Lower bills  Faster LCT adoption  Less disruption

8. Smart Street trial design
Two years One week on One week off
Five trial techniques
LV voltage control
LV network management and interconnection
HV voltage control
HV network management and interconnection
Network configuration and voltage optimisation
One year’s worth of data
To be designed to avoid placebo affect
Five trial regimes to test full effects

9. LV capacitors in street furniture
One on each closed ring
Tried and tested high spec

10. 4 ground mounted HV capacitors
Housed in containers but not on street
4 pole mounted HV capacitors
Installed similar to pole mounted transformers
There will also be 4 ground mounted HV capacitors (housed in containers as the LV but not on street) ....
...and 4 pole mounted HV capacitors installed in similar way to pole mounted transformers

LCTs rapidly surpass voltage and thermal network capacity

16. Smart Street – the first interventionW C L W
Low cost  Quick fit  Minimal disruption  Low carbon  Low loss  Invisible to customers
Voltage stabilised across the load range  Power flows optimised

17. Lower carbon footprint
Why Smart Street?
Cost reduction
Supply complexity
Improved reliability
Increased capacity
Lower carbon footprint

18. Efficient network solutions  Energy savings  Carbon benefits
Smart Street benefits
Now we can stabilise voltage
We can set the voltage level lower
This will lead to:
Reduced demand
Reduced customer energy consumption
Maximised DG output
How much could customers save? GB
Reinforcement savings via DUoS
£8.6b over 25 years
£330 over 25 years
Reduced energy consumption, 2013 (from CVR ≈ 3 - 7%)
£15 - £30 pa
£390 - £780m pa
Maximise DG output (from maximising Feed In Tariff income)
£70 pa
£20m pa
Efficient network solutions  Energy savings  Carbon benefits

19. Lower carbon footprint
Why Smart Street?
Cost reduction
Supply complexity
Improved reliability
Increased capacity
Lower carbon footprint

20. Existing radial network
Network limitations
Diversity between feeders is untapped
Fuses unable to cope with cold load pick up
Customer impact
Customers’ needs invisible to the network
Demand and generation levels limited by passive voltage control systems
Reliability driven by fix on fail
