Demand Response Research and Capabilities at LBNL Chuck Goldman Lawrence Berkeley National Laboratory Midwest Demand Response Initiative Steering Committee Kick-Off Meeting Chicago, Illinois February 9, 2007

Overview of DR Research at LBNL  Electricity Markets and Policy Group  Conducts research and provides technical assistance to policymakers on demand response –and utility system planning, energy efficiency, renewable energy, power system reliability, and DG  Demand Response Research Center  LBNL manages a multi-institutional center for DR research, funded by the California Energy Commission’s Public Interest Energy Research Program  LBNL projects focus on developing technologies and protocols for Automated Demand Response (Auto-DR) for C/I customers

DR Market Assessment & Valuation  Estimating Demand Response Potential Among Large Commercial and Industrial Customers: A Scoping Study  Develops analytical techniques and identifies data sources for conducting demand response market potential studies  Benefits of Demand Response in Electricity Markets and Recommendations for Achieving Them  A DOE Report to U.S. Congress (Section 1252 of the Energy Policy Act of 2005)  Framework for assessing DR Benefits (and costs); comparative review of existing studies; high-level policy recommendations for developing DR nation-wide

Tracking DR and RTP Program Experience  DR Program Activity and Impacts: Summer 2006  Interviewed ~30 ISO/utility program managers to assess DR program experience; snapshot of “state of DR market”  Real-time Hourly Pricing as a Default Service Tariff  Conducted stakeholder interviews and in-depth review of regulatory records in all five states where RTP hourly pricing had been adopted as the default service for large customers (through Summer 2004)  Characterized experiences with, and potential for, this form of dynamic pricing to serve as a source of demand response  Survey of Utility Experiences with RTP as an Optional Service  Conducted interviews with ~40 utilities offering optional RTP programs to characterize their actual/potential role as a source of DR

DR and RTP Program Evaluation  Niagara Mohawk (National Grid) Day-Ahead RTP for Large C&I Customers  Estimated price elasticities for 120 customers for five years; characterize price responsiveness across customer market segments; and DR potential  In-depth customer interviews; assess factors affecting participation in hourly pricing and price responsiveness  Evaluation of NYISO DR Programs (2001, 2002)  Customer survey: barriers, factors influencing decisions to participate, curtail; role of enabling technologies  Estimated customer price elasticities and market benefits

DR Technical Assistance  Direct Technical Assistance  Technical Advisor to New-England Demand Response Initiative (NEDRI)  IEA Demand Response Resource (DRR) Program and Market Analysis project  ISO-NE DR Program Design  New Jersey Multi-year DR Strategic Plan  NYSERDA DR Programs  Measurement & Verification Methods  Developed M&V Protocol for New England ISO (and NYISO) DR program for non-interval metered customers
