What is AMI (aka Smart Metering)? Advanced Metering Infrastructure (AMI) AMI is a smart metering solution that provides two way communications between an AMI system and various metering devices An AMI system is capable of collecting & analysing meter data, including meter energy usage, events, power quality information and many more AMI is an end-to-end solution, including, systems, Data Concentrators, metering devices and Customer Interface Units (CIU) Dave Tarr | © Landis+Gyr | March 29, 2019 | PUBLIC 2

Why use AMI / SMART Prepayment Solution? REDUCE DEBTS / ARREARS • Late/non payments • Increasing debt / arrears • • Prepayment (upfront) Arrears collection through vending system REDUCE ADMIN. COSTS • Disconnect/reconnect remotely • Remote connect & disconnect of supply control switch Dave Tarr | © Landis+Gyr | March 29, 2019 | PUBLIC MONITOR FRAUD • Preventing revenue collection • • Tamper functionality Fraud monitoring with AMI system PV/SSEG Support • Import and export energy measurement • Four quadrant measurement & charge registers for prepayment REMOTE METER ACCESS • Field evaluations • Customer queries • • Remote meter reading Auditing of the meters (from your office) LOAD MANAGEMENT • Remote changes to demand thresholds • • AMI system Change monitored threshold value (+P) 3

Typical Installation – Split Smart meters BENEFITS: - Enhanced revenue protection - Remote meter auditing- reduced operational cost - Read meter registers remotely - Load limiting, tamper sensing, power quality data for improved network analysis - Remote disconnection and reconnection - Import and export registers (for PV/SSEG support) - Remote device firmware update House The Customer Interface Unit (CIU) simply plugs into electrical outlet in the house. The CIU provides an interface for the customer to check electricity consumption, rate information, instantaneous power etc. In prepayment mode, the customer may enter credit tokens into the keypad C -PL G 3 Data Concentrator SMART Split Meter The split meter is typically installed outside the house, in a street or pole top kiosk G 3 -PLC Dave Tarr | © Landis+Gyr | March 29, 2019 | PUBLIC The PLC communications links the CIU to the meter. The CIU must be paired to the meter (using meter serial number) G 3 -PLC Customer Interface Unit G 3 -PLC 14

Instantaneous Values - Locally Instantaneous Values - Meter instantaneous values may be read using a meter software tool - Prepayment values may be saved in text file format or exported to MS Excel - Powerful on site (or workshop) fault finding features which enables the analysis & capture of instantaneous values on site - Same values may be remotely read by the Smart Meter system Dave Tarr | © Landis+Gyr | March 29, 2019 | PUBLIC 18

Instantaneous Values - Remotely Instantaneous Values - When meter is installed in an on-line mode, with Data Concentrator and Smart Meter System, then available instantaneous values may be accessed remotely -- Prepayment credit -- Power quality information -- Voltage, current, PF, frequency, power etc. - Powerful remote auditing and fault finding features - Reduces operating costs of the utility as this level of meter analysis and auditing can be done by Utility Engineers from the office Dave Tarr | © Landis+Gyr | March 29, 2019 | PUBLIC 19
