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
