Keypad / Card PPM Shortcomings• One Way Communications
– Essentially, Token based, one way communications, no or slow info back from meter
– Stand-alone,Meter Movements not traced (when customer moves, they sometimes moves meter with because of existing credit on meter)
• Majority is non-split making it easy to tamper with• Zero consumption users easy to ID but low consumption
gets away • Requires intensive management effort with regular
expensive inspectionsNet result is that a vast number of such meters are bypassed,
or non functional but is left as isThe customer base is simply too big to manage by means of
inspections

Key Success Factors for successful revenue protection
• Political & Management will to enforce required actions to ensure payments
• Processes, Structures & Procedures– Compromises leads to losses
• Technology
• There must be a Business Case

Success Factors Analyzed• Political & Management Will
– Have to be consistent in credit policy implementation
– Show no weakness, no compromise
– Segregate the political & business goals
• Processes, Structures & Procedures– Involve the community
– Communications & Education is of prime importance
![Page 8: Advanced Energy & Revenue Management System · Advanced Energy & Revenue Management System Performance you can rely on Dr. Pukhraj Singh, GERT GOUS & ARIF PETIWALA . ... tampering](https://reader035.vdocuments.mx/reader035/viewer/2022062908/5acaf8027f8b9a6b578e07bf/html5/thumbnails/8.jpg)
Technology Success Factors Analyzed • Split
– Reduce tampering by moving meter away from customer premises– Improve own access to meters; In-house inspections extremely
ineffective:• Typically less than 30% success in access to premises• Expensive
• AMR / bi-directional communications– Short Tamper -> Detection time allows you to manage the
payment/theft culture– Convenience– Customer detailed consumption, tampering and buying history– Easy, fast and cost-effective updates on tariffs etc
• Prepayment / Post payment– Manage customers according to their risk profile– Individual customers switch-over

Technology Factors 2
• Best Fit Technologies (CAPEX and OPEX)– PLC last mile
• Inexpensive• No additional infrastructure/wires required
– GPRS interconnectivity• Very cost effective (APN/VPN with Reverse Billing)• Wide coverage• Geographical position independence of building blocks creates
flexibility
– Vending system : Flexibility is important• Unmanned 24/7; Manned• Banks, ATM’s• 3rd party POS• Must be On-Line• Standardized XMLVend

Business Case Issues 3
• Price/Cost not only consideration
• Net improvement = improved revenue + Reduction in Losses – capital cost –increase in operational costs
• If customers pay you do not need a PPM system
• Customer inconvenienced
• Higher capital costs than conventional meters
