DR Value Proposition – AutoDR Design Advantages

AutoDR is not a program or a technology.
AutoDR is an information model that provides…
1. Open, interoperable signaling communication and technology platform
a) Provides customers with automated, electronic price and reliability signals.
b) Provides customers with capability to automate customized site-specific DR strategies.
2. Provides utilities with dispatchable operational capability similar to conventional generation resources.
3. 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.

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.

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
o improves participation
o Increases value by facilitating simultaneous economic and reliability applications

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.
