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.

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

EDF projects to prepare for 2007 deregulation of residential sector

• Internet meter

• New reference design, to be provided to multiple manufacturers

• Improved capability of remotely reconfiguring the meters

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.

Example use cases to demonstrate the functional requirements

• Direct load control

• Critical peak pricing for peak shaving based on CEC demand response activities

• Real time pricing applications

• Fast reserve service - consumer load used as a virtual reserve for distribution operations

• Customer energy information service

• Outage notification and integration with OMS

Copyright EPRI 2005

Next steps

• Reference design for priority functions

• Telecommunications assessment – how do telecommunications technology influence the consumer portal functionality and requirements?

• Development of data object models

• Pilot projects and demonstrations of important functionality – EDF IP meter– California Advanced Metering Initiative and

Demand Response initiatives– PSE&G Residential demand response pilots– ConEd BPLC pilot project– others
