Opportunities New Smart meters New markets More open Storage technology regulation Access to more Demand side Provision of Automation data response Incentives response services Weezap 8

Our strategy Offer new services and Maximise choice for the use of existing future assets Delivering Generate value to value for Innovative customers customers solutions ‘Fit and forget’ now to real problems Proven technology deployable today 9

Innovation themes Safety & Network Capacity Efficiency Customer Commercial environment resilience service evolution Strive to Improve Maximise the Provide our Improve Change our continuously network use of existing existing customer role from improve safety performance assets to services at experience, network and reduce and reduce risk increase lower cost offer new operator to impact on the demand and services and system environment generation more choice operator capacity 10

Project Overview Ben Ingham Innovation Engineer 11

Background Historic networks LCTs create Customer Smart Street Conservation have no active network issues generation could stabilises voltage voltage reduction voltage regulation cause voltage to across the load Customer Stabilised voltage exceed statutory range and demand could can be lowered voltage limits optimises power cause voltage to making our flows dip below network and statutory limits customers’ appliances more efficient 12

Project overview £11.5m, Started in Jan Trials period Extensive Quicker four-year 2014 and Jan 2016 – customer connection of innovation finishes in Apr Dec 2017 engagement LCTs project 2018 programme Lower energy throughout bills project Improved supply reliability 13

Trial overview Six primary substations 67,000 customers Wigton & Egremont 11 HV circuits – five closable HV rings Three pole-mounted HV capacitors Three ground-mounted HV capacitors 38 distribution substations Five OLTC transformers Wigan & Leigh Manchester Five substation capacitors 79 LV circuit capacitors 32

Trials overview 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 33

Initial trial design Two years Five trial techniques Two weeks on LV voltage control Two weeks off LV network management and One year’s worth of interconnection Smart Street data HV voltage control To be designed to HV network management and avoid placebo affect interconnection Five trial regimes to Network configuration and voltage test full effects optimisation 34

Aims of trials Quantification of Validation of Identify potential benefits optimisation power quality and techniques customer side impacts 35

Issues with initial trials Due to installation problems all Modified trial regime devices enabled when showed CVR working optimisation on ! Software issues led to a change in Further amendments to trial to get parameters best out of learning 36
