2 Abstract.. This presentation leads into the topic of Advanced Revenue: Large Power Users in a Smart Meter AMI Program. Case Study: Prepayment, the bigger picture for a Smart Metering Program 1. What is the benefit of prepaid to the Bulk and LPU C&I consumers? 2. How does a Utility introduce complex electricity tariffs into LPU prepaid such as: Linear Tiered Max Demand Above linked to Time of Use (TOU) etc 3. How does a Utility manage the transition from post-paid to prepaid using a Smart Metering AMI Advanced Revenue Program? 4. How does a Utility managed Disconnects Reconnects for LPU s? Page 2 SARPA - Aug 2017

3 Large Medium Power Users (LPU MPU) What the benefit is of prepaid to the consumer? Large Medium Power Users (LPU MPU). LPU Multiple meters per account High Accuracy meters: (typically 0.2 and 0.2S three phase CT meters) Positive Cash Flow typically minus 15 debtor days due to prepayment Data is instant not waiting for days for bill to arrive with post-consumption meter data Real time account reconciliation MPU Multiple meters per account High and Medium Accuracy meters: (typically 0.5 to 1.0 three phase CT or DC meters) Positive Cash Flow typically minus 15 debtor days due to prepayment Data is instant not waiting for days for bill to arrive with post-consumption meter data Real time account reconciliation Page 3 SARPA - Aug 2017

4 Large Medium Power Users (LPU MPU) What the benefit is of prepaid to the consumer? Large Medium Power Users (LPU MPU). LPU Real time complex tariff rating: TOU Max Demand etc No manual meter reading and data capture reduces inaccurate billing to zero Meter tampering alerts and events reduce NTL CT PT ratio detection MPU Real time complex tariff rating: TOU Max Demand etc No manual meter reading and data capture reduces inaccurate billing to zero Meter tampering alerts and events reduce NTL CT PT ratio detection Phase data measurement and detection Phase data measurement and detection Meter Population: 1% Meter Population: 29% Total Revenue: 50% Total Revenue: 30% Page 4 SARPA - Aug 2017

6 Large Medium Power Users (LPU MPU) Prepayment for Large Medium Power Users (LPU MPU) The benefits for LPU MPU s in a prepayment environment are:- LPU users can download and view online data in terms of real time consumption, billing data etc LPU consumer are able to plan according to real time data (e.g. when to switch on their smelter etc) Account reconciliation happens in a real time mode No manual meter reading and inaccurate data Tariff rating is done in real time and therefore they can determine their costs despite the tariff codes being complex Cash flow management the customer can pay according to their cash flow and consumption plan Strategy, as well as optimise cost saving etc Page 6 SARPA - Aug 2017

Prepayment Benefits Benefits of full Smart Metering AMI advanced revenue to the Utility Municipality Benefits of AMI prepayment to Utilities Municipalities are:- Utility cash flow typically moves

9 Prepayment Benefits Benefits of full Smart Metering AMI advanced revenue to the Utility Municipality Benefits of AMI prepayment to Utilities Municipalities are:- Utility cash flow typically moves from 150 debtor days to minus 10 to 15 days This means that the Utility gets cash in advance before electricity consumption thus allowing for growth planning and strategy. Real time data is available to the Utility Allows for planning, growth and value add support to the end consumer, be it LPU s MPU s or SPU s Grid control is enhanced as a real time view of load consumption and trends is available. Depending on the MDM, this type of data can be linked into a SCADA system for grid control applications such as DRMS, Load Management etc Page 9 SARPA - Aug 2017

11 Smart-Meter Backend-Solution Core Applications of the Solution UDIS EnergyIP Head End System UDIS Interfaces with meters to pull meter reads and events via secured connection. It also triggers additional services like remote (dis)connections. UDIS stores raw data in DB and pushes structured data to IEC adapter. Meter Data Management System MDM Processes and analysis meter reads and events. It matches customer data with meter data. After processing it forwards reads and event data to PPES via DTS (Data Transfer Service). EnergyIP Prepay PrePayment Energy System PPES Applies different tariff structures to consumption data and performs rating of consumption data. It automatically triggers remote disconnect / reconnects as required via head-end system. Provides customer usage and payment portal and performs customer wallet deductions and recharges.

12 Smart Electricity Water and Gas Benefits of combining Smart Electricity Water and Gas Meters Page 12 SARPA - Aug 2017

13 Smart Water and Gas How do Water and Gas Meters interface into the same AMI Backend? One of the most pressing issues to a utility or municipality is revenue collection and profitability. Electricity revenue is very important to both a utility and municipality as budget allocation is very high. In a water department, there are high costs with, normally, large revenue losses and no profitability. Combining Electricity Water and Gas Meters onto one system allows for: Instant view of all the meters with one end user portal login. Instant account and meter data visibility for the consumer more consumer centric control? Ease of information and electricity payment using smart phone apps etc. Improved cash flow i.e. reduce debtor days? Combined Central Wallet allows for easy revenue collection and security of revenue Page 13 SARPA - Aug 2017
