1 The Demand Response Automation Server (DRAS) Ed Koch CTO Akuacom

2 Agenda Definition and history of Open Automated Demand Response (OpenADR) concept Empirical results from Automated Demand Response in CA DRAS concept and what is being standardized with OpenADR Standards effort and status

3 Energy Management/DR Spectrum Service Levels Optimized Service Levels Temporarily Reduced

4 History Research begun at LBNL Demand Response Research Center (DRRC) into automated DR. Funded by CEC and PIER Initial development at DRRC using XML exchange of information with limited field trials Use of internet relays in field trials to support automation with simple, scaled up field tests Development of DRAS concept. Collaboration with PG&E s CPP DR program Expanded field trials and use in PG&E s Pilot DR programs. Development of CLIR box for use as Simple DRAS Client & 2008 Commercialization and use of DRAS in PG&E, SCE, and SDG&E DR programs Standardization effort for Open-ADR begins
