EdF Programs in Demand Response Anne-Lise Didierjean - EdF Mark McGranaghan – EPRI Solutions (representing the Intelligrid Consortium Consumer Portal Project)
122.6 GWe total installed capacity, 22% of total generation capacity of Europe • 42 million customers, 26 countries • France: 27 million customers • 2004, 70% of the market deregulated (C&I) • 2007, market 100%deregulated • UK EDF Energy :5 million customers, market 100% deregulated
Demand Response Applications • Reduce peak demand • Load leveling • Replace expensive generation for short term peak loads
PREDICTION(Energy Branch) MONITORING(Networks Branch) CentralTeleswitchControl Unit CONTROL(Customers Branch) BBC message assembler Grid supply points Mainsub-stations Radio Transmitter Local sub-stations Customers Fast Reserve Service – EDFenergy – UKCreating value from existing interfaces: radio EDF Energy introduced new technology which allowed forecasting, control and monitoring of load centrally
Fast Reserve Service – EDFenergy - UK • Capability to start Fast Reserve delivery within 2 minutes of instruction • Delivery rate of Fast Reserve > 25MW / minute • Capability to sustain output for > 15 minutes
EDF Tariffs and Meters in France Industrial 130,000 customers 45% electronic meters Ps > 250 kW Around $1000 6,000 /year Small Business 240,000 customers 52% electronic meters 250 kW> Ps > 36 kW Around $250 20,000 /year deregulated deregulated in 2007 Residential 27,000,000 customers 30% electronic meters Ps < 36 kW Under $30 1,000,000 /year Total = $53M/year
Flat rate EDF Tariff options for residential customers Residential 27.000.000 customers Share of electronic : 30% of the meters • Flat rate - 18 million customers • Peak hours - 8 million customers • 8 off-peak hours (-40%) on night or day • Load control of water heaters • Monthly subscription • Tempo tariff: abandoned • 3 steps of price, day ahead alert • 400 000 customers
EDF Tariffs options for residential customers Residential 27.000.000 customers Share of electronic : 30% of the meters • Critical peak pricing – 900,000 customers • +800% • 22 peak days maximum during winter • (max. 5 consecutive days) • day ahead alert
Example of a residential meter • 8 million meters installed with integrated ripple control receiver • TOU Tariffs • Contact outputs for load management • Price < $30 • 20 years reliability • units failure <0.5 %
Beyond the residential meters: manufacturers devices Peak hours relay Plug for domestic appliances Advanced Energy Management Systems Tempo tariffs modules
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
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.
Project Approach Scoping Study Technology Assessment/ Market Studies Additional Business Case Evaluations Intelligrid Architecture Requirements Definition/ Reference Design Information Models For Individual Applications Demonstrations/ Trial Applications
Requirements Definition • Define requirements for the full range of Consumer Portal functions • Build on Intelligrid Architecture Use Cases in the end use area • Build on CEC reference design • Use Intelligrid methods and formats • Gather stakeholder input Stakeholders Team
Model for defining requirements Consumer information and control Consumer Portal Information needed by consumer Information to consumer equipment for intelligent applications (e.g. price signals) Control signals for consumer loads and equipment Control signals to consumer loads and equipment (e.g. direct load control) Alarms for utility applications Information needed by utility about consumer loads and equipment Consumer equipment information (response, load characteristics, etc.) METER

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
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
