Smart Street overview New controllable switching devices stabilise voltage Allows us to lower voltage levels Enables networks and appliances to work in harmony C L W W Low cost Quick fit Minimal disruption Low carbon Low loss Invisible to customers Faster connection of low carbon technologies 7
Key activities to date Jan 2014 April 2015 Site Customer Circuit Customer Technology Project selection design engagement mailings installation mobilisation complete Project Trial circuits Design Customer Engaged Technology team identified methodology engagement with installation appointed developed plan customers and On site then applied on trial commission Contracts surveys Project to trial circuits -ing signed with completed website live circuits ongoing project partners Circuit designs finalised Knowledge sharing and dissemination 8
Customer impact and objectives Pre-trial During/post-trial ! Customers have Occasional Reduction in Possible change seen increased planned supply fault duration in voltage activity while interruptions due during trial equipment is to equipment period installed installation Objective: To engage with Objective: To prove that customers customers and explain impact of will not perceive a change to their Smart Street trial electricity supply 9
Progress and next steps Go live of the Customers Technology Customer Engaged Customer Smart Street affected by installation engagement customer leaflet website and new street enquiries / plan submitted panels held designed and social media furniture complaints to Ofgem and and lessons distributed to forums installations resolved approved learned customers on notified published trial circuits Successful technical installation as a result of well planned strategy and customer engagement activities Further ECPs to Ongoing Next Brief ENW contact Produce report of gauge customer engagement with centre before trial customer steps perception & customers during go live research findings acceptability of trials trial 10

Agenda Trial network overview Test regimes Proposed test schedule Research overview 20
Smart Street trial overview 6 primary substations 67,500 customers Wigton & Egremont 11 HV circuits – 5 closable HV rings 4 pole mounted HV capacitors 3 ground mounted HV capacitors 38 distribution substations 5 OLTC transformers Wigan & Leigh Manchester 5 substation capacitors 79 LV circuit capacitors 21
Smart Street trial design Two years Five trial techniques One week on LV voltage control One week off LV network management One year’s worth of and interconnection Smart Street data HV voltage control To be designed to HV network management avoid placebo affect and interconnection Five trial regimes to Network configuration test full effects and voltage optimisation 22
Smart Street test regimes Smart Street trial Test regime 1. On-load tap changing distribution transformer only 2. On-load tap changing distribution transformer and capacitor(s) on LV circuits LV voltage control 3. Capacitors at distribution substation only 4. Capacitors at distribution substation and on LV circuits 5. Capacitor(s) on LV circuits only 1. LV radial circuits LV network management & interconnection 2. LV interconnected circuits 1. Voltage controllers at primary substation only HV voltage control 2. Voltage controllers at primary substation and capacitor(s) on HV circuits 1. HV radial circuits HV network management & interconnection 2. HV interconnected circuits 1. Losses reduction Network configuration & voltage optimisation 2. Energy consumption reduction 23
