Problem

• Major 1,000,000 customer network with 35,000 LV transformers covering 29,000km of low voltage circuits
• High and variable voltages across LV network caused by rapid deployment of rooftop solar
• High voltage triggers inverter lockout at 255V and cause broader increase in customer consumption, higher CO2 emissions, appliance failures
• Large scale solar deployment can result in localised phase imbalance

Solution

• Edge Zero real time power quality, voltage and phase balance data monitoring at individual transformer and LV circuit level
• Edge Zero platform automated notification of live fault and non-compliance power quality data to network operators
• Edge Zero platform automated kWh, $ and CO2 savings calculations based on voltage controls and phase re-balance
• Edge Zero platform prioritises voltage and power quality management remediation based on customers affected, cost of non-compliance, regulatory KPIs

Outcomes

• Commercial rollout program for over 12,500 monitors across Strong NPV and opex savings through improved power quality, voltage management
• Voltage management leads to reduced kWh consumption and lower CO2 emissions
• Identification of actual/potential faults and reduced customer outages
• Transformer loading analysis and improved transformer life
• Improved customer satisfaction

Edge Zero Advantage

• Real time, real data visibility at an asset level enables more accurate data calculation than deemed utilisation from AMI and grid model calculations
• Live installation of Edge monitors reduces customer disruption
• Real time, automated notifications to network operators
• Automated cost-benefit analysis on remediation strategies
• Live, asset level data supports regulatory case for augmentation capex/opex
