Costs - Investment Breakdown per point of delivery 66% 7% 20% 7% mart Meters Data Concentrators Installation System Single Phase meters Three Phase meters Three phase meters with CT Sockets Concentrators Switches Modems Sockets Boxes for outdoor installation External antennas Replacement of old meters Meters and Concentrators installation Meters and concentrators logistics and transport PDAs SW licences Infrasctrucuture (TLC, HW, internal network) Human resources for professional services, system integration verage per p.o.d: 3-80 (depending on the eters models breakdown) Average per p.o.d: 5-9 (depending on the meters per concentrator) Average per p.o.d: Strongly dependent on local market conditions and internal activities 80 120 per point of delivery up to date 15
Costs Operating Costs Yearly running costs Low Cost High Cost Telecommunication costs: Communication between meters and data concentrators is free, using a Utility Owned Infrastructure. Communication costs between concentrators and Central System depend upon the local TLC companies prices. According to our best estimation, based on Italian experience, the yearly average time of transmission for every customer is 6 minutes. AMM headquarter and team: People assigned to help desk for the territory, technical back office, monitoring and reporting. They can be roughly considered 3 FTE for each million customers New installations due to meters or concentrators failure According to Italian Telegestore, yearly running costs best estimation are up to 2 per point of delivery 16
Savings Yearly savings 0% savings 100% savings Field Operations and Logistics: Meters replacement due to failure reduced by 70% with respect to dynamic meters Contract parameter modification reduced by 95%, only modification for single-poly phase switching and system failure (less than 2%) Activation and deactivation reduced by 99% Readings on field reduced by 99% Logistic costs reduced by 80% due to standardization of models (only three) Energy Losses: Energy balance for each transformer and antitamper signals allow more accurate fraud contrast increasing the success rate up to 50% Credit Control and Management: Bad payers remote deactivation avoids customer to continue consuming and increasing their own debt Monthly readings improve correctness of energy balance and optimize cash According to Italian Telegestore experience, savings are up to 14 per point of delivery 17
