Key Projects

7 7

1st Wave: Smart Meter Roll-Out and Exploitation

Status: Smart Meters Deployed

• Smart meters deployed >97% UE’s customers.

• Base meter operations:

• Data to market (99.8%) by 6am

• Security capabilities deployed

• Support organization effciency

• Standardised Device Fleet

First Wave Benefits:

• Consumer access to consumption

• Flexible tariffs

• Remote Discon/Recon (60,000pa)

• Remote solar configuration (5,000pa)

• Meter location identification & energy theft

• Meter data used in UE Network Investment

Benefit Realisation (2010 – 2014)

2nd Wave – Alternative Energy Management Models

Status: Trials Providing Insights

Demand Trials - Five Targeted Models

• Residential: Voluntary Demand Response

• Residential: Capacity Management - “Limit Your Load”

• Managed Appliance – “SmartAC” & “Pool Saver”

• Large Site curtailed load - Demand Aggregator

• Storage – Customer & Network benefits model

Benefits:

• Customer integrated into energy management

• Alternative network investment model

• Alternatives to bulk load shed

• Examine network control operations (wip)

• Explore marginal investment per kW (Initial findings)

UE Demand Response: 2013 – Ongoing

9 9

3rd Wave – Outage Management Integration

Status: OUNMS upgraded & smart meter integration

• Isolate Customer-side fault vs Network-side fault

• Create outage tickets through processing ‘last gasp’

via integration outage management system

• Website update in real time for customer to view

known outage information, with more granularity.

Benefits:

• Meter ‘Ping’: Consumer is able to call REC at

beginning of the outage rather than 1 or 2 hrs later…

• Wasted truck visits halved in 2 years

• Consumer can check mobile, website, social media

for outages before contacting outage call centre.

Customer Outage Detection (2013 – )

4th Wave – Digital Metering Exploitation & Integration

Status: 5-Minute Analytics & OUNMS integration

• Meter engineering data analysis finds at-premise issues

• Predictive algorithms identify neutral integrity & service

issues at > 95% success rates (>300 cases in 6 months)

• Network pattern analysis to predict network impedance

and connectivity conditions

• Removing one-off LV issues is creating a clearer voltage

profile & power flow model for the network

• Remote phase identification - LV utilization, reduce faults

Benefits:

• Avoids consumer electric shock, potential electrocution

• Meet ESV obligation on safety, voltage management

• Reduces number & impact of customer outages (“Find

before Failure”)

Safety & Predicted Network Outages (2015 – )

5th Wave – Network Operations - Grid Exploitation

Status: Exploiting HV Control System upgrades

• Group Controls: eg. Total Fire Ban settings, Gas sections

• Meter analytics integration with HV for network control

• FLISR to ~450 feeders: Faster outage switching!

• Power Flow – Improved fault location analysis (wip)

• Progression from HV to LV network management

• New skills / structure in support organization required

Benefits:

• Reduce customer outage times to momentary (< 1 min)

• Better identification of network fault location

• Network voltage compliance using customer meter data

• Reduce LV mins off supply / customer interruptions

Network Operations Improvements (2016 – )

Integrated Security Model for Smart Grid

Status: Reviewing all security aspects

• Phishing and emergency exercises - awareness

• External & internal access management – constrain roles

• Application, firmware refresh cycles – software currency

• Targeted penetration tests and audits – find the holes

• Segmentation, isolation and encryption – limit the hit

• SIEM for real time environments – monitor traffic

Integrated Security Operations (2015 – Ongoing)

Benefits:

• Inter-agency working

• Rapid identification and

response to security events

• Limit the damage when it

occurs, …known recovery

processes

13 13

Integrated Change Control & Support Model

Status: Early Stages of a journey

• Network Asset change processes

• Standardise & manage device fleet

• Integrate testing environments & facilities –

drive test automation…

• Deploy quality change control tools

• “Integration” knowledge centre…

• Redundancy & DR processes

• Integrated change operations & support

Benefits:

• Avoid change-failure cases driven by IT, OT,

and network changes not in sync.

• High availability of service operations

• Timeliness of change execution
