• EMCO Limited (India) &GRINPAL ENERGY Pty Ltd (South Africa)a division of SAAB Group
• Collaboration offers a high packed powerful combination of
• Latest state-of-the-art technology,
• Strong field experience,
• Diversified but an extremely rich combination of R&D teams,
• Manufacturing excellence,
• Local presence & cost competitiveness
A High Technology Partnership
Advanced Prepayment Solution(ISMS 2nd Generation)
• 1st generation PPM (keypad, etc) shortcomings
• Key Success Factors for a successful PPM• Grinpal Technology Solution
– System Overview– Some Advanced Features
• Case Studies• Conclusion
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
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
System Overview
Some Features (1)
• Multiple levels of theft prevention:– Transformer level Energy Recon/Energy Audit
• Box/kiosk level Energy Recon/Audit– Individual meter bypass detection
– Split meter inside secure enclosure with Door Tamper Alarm
– Alarms SMS to Cell Phone for prompt reaction– NO means of tampering that can not be detected
and alarmed by the system– Some alarms
• Meter bypassed• Meter error• No units consumed in 24 hrs• Contactor failure• MCB tripped• No communication to Display Unit• Door Opened
Some Features (2)
• Detailed Consumption reports• AMR Readings possible on daily basis• Scheduler takes care of recurring tasks• Distributed processing (Cell Concentrators)• Arrears collection (per individual agreement)• Automatic disconnection/connection according to
15 different policy groups• Consumer cut-off on High Voltage/Low Voltage
(limits settable to protect consumer electronics)
Some Features(3)
• On-line, real time change/download of parameters – Switching between PPM or Post payment– Tariffs
• Enhanced Installation, Commission and Maintenance Capabilities– GPS positions captured via PDA for infrastructure &
Customer – Enhanced customer data integrity. Electronic
installation & maintenance job cards, submitted and accepted/rejected in real time
– High level of automation of number capturing and propagation through the system
Some Features(4)
• Cell phones interactive interface– Meter readings– Send Bills, Payment Reminders, Warnings
• Central Software Web-based interfaces allowing access from any geographic position
• Integrated Summation/Check metering – Per transformer– Per metering kiosk
• Load Management – Current Limit / customer– Consumption Limit / customer– Load Management (hot water cylinders)
• Optional Alpha Numeric Text Messaging
