1 Best Practices, Design Guidelines and Standards
National Town Meeting on Demand Response Washington, DC June 3, 2008 Best Practices, Design Guidelines and Standards A Demand Response Research Center Progress Report Roger Levy Program Development and Outreach Demand Response Research Center Lawrence Berkeley National Laboratory

2 Communication Standard
Demand Response Progress DRRC research is supporting the California Public Utilities Commission and California Energy Commission to develop Demand Response best practices, guidelines and standards. Building Standard Global Temperature Setback (Title 24, 2008) Open Automated Demand Response – communication/information model Programmable Communicating Thermostat Reference Design (Title 24 – under review) Default Dynamic Pricing (CPUC Ruling for PG&E and SDG&E) Communication Standard Reference Design Best Practice

3 DRRC Challenge Objective to develop, prioritize, conduct, and disseminate multi-institutional research to facilitate DR Improve DR effectiveness Improve DR reliability and reliability Reduce cost Scope Focus on technologies, policies, programs, strategies and practices that emphasize A market based approach Customer Choice.

4 DR Value Proposition – AutoDR Design Advantages
Market-Based Price Responsive DR Conventional Program-Based DR Participation Targeted, Limited All Customers Value of DR Utility Value Customer Value DR-EE Link No Integration Integrated Equipment Utility Provided Few Suppliers Customer Provided Customization Utility defined Customer Defined Participation, Baseline Issues Performance, No Baseline Incentives Automation Not Required Required

5 What is AutoDR AutoDR is not a program or a technology.
Communication Standard AutoDR is not a program or a technology. AutoDR is an information model that provides… Open, interoperable signaling communication and technology platform Provides customers with automated, electronic price and reliability signals. Provides customers with capability to automate customized site-specific DR strategies. Provides utilities with dispatchable operational capability similar to conventional generation resources. Supports all DR direct control, emergency, bidding, and pricing options. AutoDR is being developed as a national communications standard through an industry consortium lead by the DRRC that includes PG&E, SCE, SDG&E, and CAISO.

8 Open AutoDR Communications Standards
Features Continuous and Reliable - Provides continuous, secure, and reliable communications infrastructure. Translation - Translates pricing, reliability and DR events into continuous, open protocol internet signals Automation – Customer established DR action(s) programmed into facility energy management systems and control equipment initiated by receipt of price, reliability, event signal. Opt-Out – Customer decides and always has the capability to decide to participate, opt-out or override any event. Complete Data Model – Describes information model and architecture to communicate price, reliability, and other DR activation signals. Scalable – Provides scalable architecture scalable Benefits No stranded technology assets - Interoperable Supports RTP - Supports states policies to promote price response.

9 Why a Standard ? Reduce barriers to DR - Integrate customer energy management and building control systems to facilitate customer response. Reduce the cost of DR – standards allow vendors and service providers to address common protocols and to develop common response strategies. Improve the effectiveness of DR – automation of “customer devised” response strategies improves participation Increases value by facilitating simultaneous economic and reliability applications

10 Standards Organizations

Building Standard GLOBAL TEMPERATURE SETBACK In facilities with multiple space-conditioning zones for comfort heating or cooling, each controlled by an individual thermostatic control, authorized personnel shall have the capability to perform Global Temperature Adjustment (GTA) of the set points of all zones simultaneously from a single location. The centrally generated GTA command shall cause the thermostatic control of each individual zone to increase cooling set points by at least 3º F and decrease heating set points by at least 3º F. EXCEPTION to Section 122 (b) 4: Systems with stand-alone thermostats that are not connected via an Energy Management and Control System (EMCS) communication network.
