California Energy Commission - Public Interest Energy Research Program Demand Response Research Center Research Objectives Objective Scope Research Goals Develop, prioritize, conduct and disseminate multi- institutional research to facilitate Demand Response. Technologies, policies, programs, strategies and practices, emphasizing a market connection Cost – develop cost effective approaches to improve DR implementation and operation Technology – evaluate the readiness of customers and buildings to support DR Capability – evaluate and develop strategies to support price and reliability response.

California Energy Commission - Public Interest Energy Research Program Demand Response Research Center “Guiding DR Design Principles ” DR Success Factors Design Principles Explanation Customer Choice Create adaptable, realistic operational strategies Minimize adverse impacts Maximize shifting and load impacts Automation Enable and simplify customer choice Enable price and reliability response Integrate DR with system operations Dynamic Rates Integrate efficiency and DR Reflect system costs and needs Establish a customer value function – “clear price and reliability signals that provide a relationship between how customers use energy and what they pay.”

California Energy Commission - Public Interest Energy Research Program Automated Demand Response (AutoDR) Targets commercial and industrial customers Provides customers with automated, electronic price and reliability signals. Provides customers with capability to automate site-specific DR strategies customized to their needs and facilities. Provide utilities with automated, dispatchable operational capability similar to conventional generation resources.

California Energy Commission - Public Interest Energy Research Program AutoDR is not a demand response program. AutoDR is an open, standardized communication and automation framework that supports all forms of DR. AutoDR expands customer choice, improves DR effectiveness and, addresses the operational needs of the CAISO, and the CPUC vision the objectives outlined in CPUC Rulemaking AutoDR is being formalized as an open communications standard through an industry consortium lead by the DRRC that includes PG&E, SCE, SDG&E, and CAISO.

California Energy Commission - Public Interest Energy Research Program Rate Transition Project Purpose Develop a framework for developing new, innovative and more equitable rate and incentive designs that simultaneously support energy efficiency and demand response. Objectives  Identify the leading issues in rate design  Identify barriers and constraints  Propose remedies and solutions  Develop strawman rate designs that illustrate the solutions  Draw out these themes in workshops  Work closely with the regulators and utilities  Guidance from a national Peer Review Group

California Energy Commission - Public Interest Energy Research Program Rate Transition Project 1. Revised Rate Design Principles 2. Recommendations for resolving rate related policy/design conflicts 3. Framework for side-by-side comparisons of rate design impacts on DR, equity, customer bills, risk, etc. Example Products

California Energy Commission - Public Interest Energy Research Program Rate Transition Project Example Products The largest impacts are produced by a default CPP/TOU for residential and medium C&I customers, and default RTP for large C&I customers The smallest impacts are produced by an optional RTP for all customers

California Energy Commission - Public Interest Energy Research Program DR Value Project 1.Summarize key observations from previous DRRC-sponsored work; 2.Compile and review prior and ongoing DR valuation research and methodology development efforts 3.Develop a provisional list of DR benefit categories that includes all forms of demand response – (1) economic (pricing),(2) reliability (emergency), and (3) financial for both wholesale and retail markets. 4.Consider benefits across stakeholders (e.g., System/Market Operators, Electricity Services Providers, Non-Participating End- use Customers; Generators; and Regulators) characteristic of each type (e.g., price-based or reliability-based) Demand Response program Objectives

Use of Reference Designs to Accelerate Commercial Adoption of Interoperable Devices and Systems Erich W. Gunther EnerNex Corporation March 3, 2008

California Energy Commission - Public Interest Energy Research Program What is a Reference Design? “Reference design refers to a technical blueprint of a system that is intended for others to copy. It contains the essential elements of the system; however, third parties may enhance or modify the design as required. The main purpose of reference design is to support companies in development of next generation products using latest technologies. The reference product is proof of the platform concept and is usually targeted for specific applications.” Source: Wikipedia
