Capacity to Customers Capacity Technical New commercial to Customers innovation contracts Utilised Current demand capacity Latent capacity Combines proven technology Remote control equipment on Innovative demand side and new commercial contracts HV circuit and close the NOP response contracts Releases significant network Enhanced network Allow us to control customer’s capacity management software consumption on a circuit at the time of fault Facilitates connection of new Effectively doubles the demand and generation available capacity of the circuit without reinforcement 7
Capacity to Customers and beyond When is C 2 C cost ... or when should effective ...? we reinforce? Working with University of Manchester to develop economic methodology 8
Customer Load Active System Services CLASS is seeking to demonstrate that electricity demand can be managed by controlling voltage…without any discernible impacts on customers System Demand Provides a demand Reduces demand balancing reduction capability reduction at time of support to support system system peak balancing Voltage control Mitigates excessive voltages when generation is high and demand is low 9
Smart Street New controllable switching devices stabilise voltage Allows us to lower voltage levels Enables networks and appliances to work in harmony Low cost Quick fit Minimal disruption Low carbon Low loss Invisible to customers Faster connection of low carbon technologies 10
Fault Level Active Response (FLARE) FLARE is the first UK demonstration of an active fault level management solution that avoids traditional network reinforcement Faster LCT adoption Less disruption Lower bills 11

Low Voltage Network Solutions Overview of project (non-academic focus) Dr Rita Shaw 3 October 2014 13
LV Network Solutions £ Our largest Tier 1 2011 - 2014 £1.5 million LCNF Fund www.enwl.co.uk/lvns Modelling and and your USBs analysis But there was more to the project…. 14
Aim of the project Improve LV Monitor 200 LV assessment and substations policy for To understand and feeders all network our LV networks To understand our LV Text networks now now and in and in future scenarios Model Assess future scenarios LV networks, monitored LV identifying LCT network impacts and performance solutions 15
LV monitoring – identify technique and deploy Challenge Develop installation procedures Site selection / surveys Determine monitoring Train installation crews requirements Prepare functional Prepare for data capture specifications £ Tender and procure Roll out to site - 28 pole equipment mounted and 172 ground 16
Monitoring equipment 2012 UK Energy Innovation award for the ‘Best Smart Grid Technology’ GridKey monitoring equipment at 100 substations 17
Monitoring equipment Nortech monitoring equipment at 100 substations 18
Communications approach Monitoring unit fitted with SIM card DPN3 Protocol Assigned private, static IP address between iHost Time stamped data logs created every 1 – 10 and monitor minutes Unsolicited iHost server at Electricity event reporting North West consists of transfers data communication modules, logs in near real databases and web user time interface GPRS / 3 G Export produces CSV files to be used by the University of Manchester 1 set of Rogowski coils fitted per LV way 3 phases and neutral measured 19
LV monitoring – outcomes 10,000 days of good 10-minute data At transformer and head of each feeder, per phase + neutral Value of monitoring within LVNS Challenging but Performance evaluation of monitored LV networks’ achieved! Review / improve load estimates for whole network Validation of network models Monitoring used in other innovation projects and BAU 20
Apart from the monitoring… Extract and transfer monitoring, network and customer data to UoM Engage with UoM analysis and outputs Leverage learning to support business 21
What we have learnt In detail for How our How to Products + procedures monitored networks LV network monitor at What parameters and Improving our ‘Load performs when/where to monitor LV Allocation’ estimates now in future for whole secondary network How our LV network will perform with LCTs Hosting capacity of underground LV networks for LCTs Potential network solutions, with implications for future DNO policy A (rough) future capacity headroom model for whole secondary network 22
Also ... LV feeder midpoint monitoring 100 midpoints and 100 endpoints outside LVNS project Smart joint technique developed by us 23
Why are we doing this? Drive value for our customers 24

Voltage Management on Low Voltage Busbars Dr Geraldine Bryson Future Networks Technical Manager 27
Aims and objectives Trial solutions to help Assess ability to Assess effectiveness Assess phase manage LV networks manage voltages in of devices to correct imbalance and and cope with real time power factor power quality changing demand 30 month project started in April 2011 costing £0.5 million 28
Trials Four techniques explored through field trials Voltage regulation using a distribution transformer with OLTC Voltage regulation using a Power Perfector on an individual LV feeder Voltage regulation using a shunt capacitor installed part way along an LV feeder Harmonic filtering, power factor correction and phase balancing via active filter 29
Distribution transformer with OLTC Commissioned June 2013 with Fundamentals and set to existing LV busbar voltage Training for TapCon230 relay Operational procedures designed to reduce impact on customers and reduce training needs Site trials use LV monitoring for results 30
Power Perfector Commissioned August 2012 Training for changing settings Operational procedures designed to reduce impact on customers and reduce training needs Site trials use LV monitoring for results and change voltage settings 31
LV capacitors Set to control volts NOT VArs Operational procedures designed to reduce impact on customers and reduce training needs Site trials use LV monitoring for Commissioned October 2013 results and change voltage settings 32
Active harmonic filters Commissioned August 2012 Operational procedures designed to reduce impact on customers and reduce training needs Site trials switch filter ON/OFF Installed full PQ monitors for results 33
University of Manchester - Modelling Monitoring Alternative Modelling data used solutions complete to verify modelled Recommendations for Future Networks 34
University of Manchester - Modelling Capacity release with OLTC 35
University of Manchester - Modelling Capacity release with capacitor installation 36
