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.

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

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

Lower carbon footprint
Why Smart Street Cost reduction Supply complexity Improved reliability Increased capacity Lower carbon footprint
13
Lower carbon footprint
Why Smart Street Cost reduction Supply complexity Improved reliability Increased capacity Lower carbon footprint
14
Historic networks have no active voltage regulation
Normal voltage range Drift range Historic networks have no active voltage regulation
15
Problem - LCTs create network issues
Drift range LCTs rapidly surpass voltage and thermal network capacity
16
Smart Street – the first intervention
W 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

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

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
