Copyright EPRI 2005 Lessons learned Demand-Response can be simple and efficient but rate engineering and simulation should help balance the economics Devil is in the details, beware hidden complexity of IT systems Standardized specifications for the meter functions and capabilities can assure compatibility with demand response programs and provide economical designs.

Copyright EPRI 2005 New Paradigm in the European market Deregulation –Utilities are willing to increase customer services to be competitive in this new market New actors in the market - require more frequent access to metering data –“Standard communication protocols must be developed by Distribution System Operator” - French regulator Proposal for a European Directive (COD 2003/0300) – Saving at least 1% more energy each year –a potential market for energy efficiency worth between 5 and 10 billion euros/yr

Copyright EPRI 2005 The IntelliGrid Consumer Portal IntelliGrid

Copyright EPRI 2005 IntelliGrid Consumer Portal Project Define requirements so that vendors can build components and systems that are interoperable (open systems). –Information models, object models Define requirements so that systems will be expandable to meet needs of future service offerings. Engage stakeholders to create a consensus on these requirements definitions. Demonstrate the feasibility and performance of systems that meet these requirements. Move these requirements into the standards process to enhance the applications in the market.

Copyright EPRI 2005 What are the applications? Current Applications (examples) AMR (radio and low speed PLC) Time of Use Rates Special load control during peak periods Direct Load Control (e.g. radio), controllable thermostats Building energy management systems DG (backup) Aggregation for Market Participation Metering information and energy analysis via website Outage detection and notification Metering aggregation for multiple sites or facilities Future Applications Continuous metering information available to customer RTP for customer market participation Integration of customer-owned generation Automatic load controls integrated with RTP Remote power quality monitoring and services Facility sub-metering and energy analysis Remote equipment performance diagnostics Outage detection integration with OMS Customer monitoring integration with real time system simulations and controls
