What does a reliable DR portfolio look like? The Market for C&I DR Either manual or automated DR Must be automated DR Must be manual DR Ex: Grocery Store Pre-authorized, fully-automated Ex: light manufacturing Ex: chemical/materials manufacturer Semi-automated Ex: Any customer who wants to opt-in or initiate the curtailment sequence on-site
Attributes of the EnerNOC data set • Data from C&I customers in US and Canada • Over 27,000 asset-dispatches from 2011 were analyzed • Average performance was evaluated without MW-weighting of results
Average Performance, Site Size, and Variability Conclusions Average performance not strongly affected by automation, especially at large sites. StDev of performance improves with automation, especially for small sites.
Dispatch Advanced Notice Rapid Response (< 20 min) Avg % Perf StdDev Normal Response (> 20 min) Conclusions Automation leads to better performance & less volatility in rapid programs. Semi-auto response is very similar to manual; suggests that getting people to opt-in quickly is commensurate with performance.
AutoDR effectiveness by Customer Vertical Conclusions Load type and ability to automate differs significantly by vertical. Automation does not always lead to improved performance.
Why doesn’t automation = guaranteed performance? • Prior operations may impact baseline. • Non-curtailed loads can still oscillate and affect DR performance. • Load shed often involves changing control set points; exact curtailment amount impacted by other variables (e.g., weather). Customer education and training is still required to ensure AutoDR performance!

“AutoDR” means different things • AutoDR is used to refer to a specific technology approach, requiring use of OpenADR protocol, and associated incentive funding program • Typically require elimination of all human intervention • Still evaluating how to fit AutoDR into the larger DR strategy • General bias in favor of open communications protocols and standards EnerNOC At LBNL and California IOUs At Other Utilities and ISOs • AutoDR is used to refer to all curtailment approaches that rely on technology that automates load shed • May or may not include use of the OpenADR protocol
What is OpenADR? Utility or ISO DRAS/DRMS A non-proprietary, open standardized DR interface that allows electricity providers to communicate DR signals directly to customers over the Internet using a common language. OpenADR design premises: • AutoDR participation will require investment in technology • Utilities seeking to expedite investment may consider providing financial incentives • Standard communications must exist to prevent this subsidized equipment from becoming stranded assets • The need for standards and interoperability will continue to increase as the smart grid matures EnerNOC NOC Site A Site B Site B2 Site B3 Site C Site D Site E
OpenADR 2.0: The Emerging Protocols • Conforms to NIST Smart Grid Interoperability Framework (formal industry standard) • Test tool, test plan and certification program • Includes support for M&V data • Expanded architecture to include pricing, telemetry and other services • Includes XMPP technology to improve scalability and reduce data latency • Open specification • No certification program • Limited number of vendors • Geared towards specific DR programs ** Note: OpenADR 2.0 is not backward compatible with 1.0 OpenADR 1.0 OpenADR 2.0
Examples of DR Automation by Vertical For many customers, automation facilitates DR participation. Examples in redbelow represent instances where DR plans are driven by automated load control.
