1. Meter Data Management – From the Smarter Grid to Future Market Platforms in Liberalized Energy Markets Sebnem Rusitschka, Siemens AG, Corporate Technology, Germany Stephan Merk, Siemens AG, Corporate Technology, Germany Dr. Heinrich Kirchauer, Siemens AG, Energy Sector, Austria Dr. Monika Sturm, Siemens AG, Energy Sector, Austria

2. Motivation and Background • E-Energy Program funded by German Federal Ministery of Economics and Technology • Field trials in six model regions • Integration of DER • Future energy market places • Smart prosumers in smart grids • E-DeMa project focus • Automation of business processes • Innovative energy products • ICT based prosumer-side energy management  Requires powerful meter data management systems

3. Scenario & Stakeholder Analysis – Status quo • Liberalization of metering business • Prosumers can choose • Metering service provider • Monthly bills • Variable tariffs • Challenges • Overburdened DSO as central data hub • Retailers have no incentives to offer variable tariffs (energy procurement acc. standard profiles) • Interruptible loads and distributed feed-in not utilized economically End User Metering Processes Metering Service Provider Retailer Processes Distribution System Operator Energy Retailer Balancing Processes Balance Responsible Party Balance Coordinator

4. Scenario & Stakeholder Analysis – Trends • Retailer procurement based on metering data and not SLP; use meter reads for forecast • Contracting of interruptible loads by DSO to defer grid expansion instead of emergency disconnects • Aggregators bundle interruptible loads and feed-ins from prosumers • Requires • Data exchange platform • Powerful meter data management End User Metering Processes Metering Service Provider Retailer Processes Distribution System Operator Energy Retailer & Aggregator Balancing Processes Balance Responsible Party Balance Coordinator

5. SMART PROSUMPTION SMART PORTFOLIO SMART METERING SMART GRID MSP RET DSO PRO Energy Market Platform Ecosystem EEX TSO E-ENERGY MARKETPLACE • data exchange hub • - market communication • - market for energy • products AGG • - Flexibility procurement planning • Detection of network problems • Variable network charges • - Procurement planning • Bundling of loads and feed-ins EEX … Energy Exchange TSO … Transmission Operator MSP … Metering Service Provider DSO … Distribution System Operator RET … Retailer AGG … Aggregator PRO … Prosumer - Automated energy management • Automated data collection • Automated roll-out and provisioning

6. Meter Data Management System Design • All roles need a set of core features • Specific roles need additional “value added services” • Data management for procurement/sales and billing • Data processing for distribution grid operations • Modular architecture • Extensible architecture • Coupled by service bus Core Features Provisioning, Collection & Delivery Data Validation Privacy & Confidentiality Protection Upstream Systems Service Bus Data Processing for Distribution Grid Management Systems Data Management for Billing & Charging Procurement planning Value-added Services For Technical Systems Commercial Systems

7. MDM Core Features • Contract based provisioning, data collection, delivery • Contract based metering granularity (intervals, registers) • Delivery as required by upstream systems • Easier tariff or retailer change • Data validation • Contract and context based validation (e.g. outage, weather) • Invalid data triggers appropriate processes (e.g. estimation, meter check) • Privacy protection and confidentiality • Balancing of business needs with privacy requirements • Filtering according to principle of data minimization

8. MDM Value Added Services • Commercial valued added services • Optimized procurement with current meter data for retailers • Balancing of aggregator contracts for DSOs • Support for complex tariffs (time-, load-dependent …) • Flexible delivery to upstream billing systems • Technical valued added services • Insight into low-voltage distribution grid • Manage DER feed-in • Optimized grid planning to reduce CAPEX • Real-time operation in a closed-loop mode to reduce OPEX

9. Conclusion • Meter data management is a central smart grid cornerstone • MDM systems offer core features and value added services for commercial and technical challenges • Loose coupling of modular architecture guarantees • extensibility to new requirements • flexible deployment for different market roles
