4. Key Facts about the Hasso Plattner Institute Research Group Hasso Plattner / Alexander Zeier Research focus: real customer data for enterprisesoftware and design of complex applications In-Memory Data Management for Enterprise Applications Human-Centered Software Design and Engineering Maintenance and Evolution of SOA Systems Integration of RFID Technology in Enterprise Platforms Cooperations Academic: Stanford, MIT, etc. Industry: SAP, Siemens, Audi, etc. SGNI/LCN2010, Enabling Real-Time Charging for Smart Grid Infrastructures, Schapranow, Oct 14, 2010 4
5. MotivationHow to measure? “If you cannot measure it,you cannot improve it!” (William Thomson, 1st Lord Kelvin) SGNI/LCN2010, Enabling Real-Time Charging for Smart Grid Infrastructures, Schapranow, Oct 14, 2010 5
6. MotivationState-of-the-art Interval: Mainly annual meter readings Type: Mainly manual or small range wireless readings What is missing? Direct feedback for customers Convenient tracking methods Real-time billing details for cost control How much personnel involvement is required?

15. Business ImpactsCurrent State: Post-payment Schema Fix contracts, e.g. for the period of 12 months Annual metering of power consumption Fixed down payments per month or quarter Pros: Not a single huge payment Cons: Over payment, when using less energy (bound money) No convenient way to measure saving impacts Provider changes are only rare SGNI/LCN2010, Enabling Real-Time Charging for Smart Grid Infrastructures, Schapranow, Oct 14, 2010 13
16. Business ImpactsFuture Outlook of Real-Time Charging Tracking of consumption on live data Instant feedback for customers Payments can be accurately adapted each month Basis for alternative payment methods, e.g. pre-paid Switching between energy providers instantly Select a certain provider for a certain time span or device Full cost control possible SGNI/LCN2010, Enabling Real-Time Charging for Smart Grid Infrastructures, Schapranow, Oct 14, 2010 14
