Demand Response Availability Data System (DADS): Phase I and II John Moura NERC Staff
Presentation Goals Provide an overview of the on-going efforts at NERC to collect historical performance data on demand response Introduce the Demand Response Availability System (DADS) to industry stakeholders and provide instruction on how to complete the required data forms for the Phase I pilot program Solicit feedback from workshop participants and answer program or organization-specific questions. Additionally, encourage continued feedback, comments, and suggestions throughout the Phase I pilot program
NERC & Demand Response
About NERC International regulatory authority for electric reliability in North America Develop & enforce reliability standards Analyze system outages and near-misses & recommend improved practices Assess current and future reliability
NERC & Demand Response Demand Response is an important component in the overall portfolio of resources required to reliably meet the increasing demands for electricity in North America. In order for NERC to carry out its responsibility to ensure the reliability of the North American bulk power system, NERC must be able to: • Evaluate and understand the benefits of Demand Response and its impact on reliability. • Quantify the performance of demand-side resources • Assess the overall characteristics of Demand Response as it relates to bulk power system planning and operations
NERC & Demand Response Recommendations and Conclusions in the 2008 and 2009 Long-Term Reliability Assessment • Additional demand-side resources could be an effective option to preserve system reliability over the next ten years. In addition, they may facilitate the integration of renewable and variable resources. • Potential reliability impacts of broad-scale use of Demand Response resources must be better understood by industry and regulators. • Better measurement and verification techniques will be needed to measure and track actual availability of Demand Response under various system conditions .
NERC & Demand Response NERC acts on these responsibilities through several activities: • Long-term assessment of Demand Response projections Long-Term Reliability Assessment • Short-term assessment of Demand Response projections Seasonal (Summer/Winter) Reliability Assessments • Other assessments or evaluations of Demand Response Demand-Side Management Task Force (completed) Integration of Variable Generation Task Force Reliability Impacts of Climate Change Initiatives Demand Response Data Task Force NERC Special Reliability Assessments

Demand Response Availability Data System (DADS) Overview
What is DADS? DADS = Demand Response Availability Data System DADS is a system that is aimed to collect demand response event and market participation information to measure the ongoing influence of demand response on reliability. The DADS will enable NERC to receive, manage, assess and disseminate data on Demand Response Programs, products and services administered by retail and wholesale entities throughout North America. DADS will serve as a resource to the industry for information about Demand Response participation and performance.
DADS Phase I & II Report The Demand Response Availability Data System Phase I and II report was approved by the NERC Planning Committee in September 2009. The report outlines the functional requirements of the Phase I and II system Provides a framework for a mandatory data request to be issued by NERC Identifies the required reporting parties, as well as the data to be collected by the system
DADS Phase I & II Phase I & II will focus on reliability or event related Demand Response which is both dispatchable and controllable. Phase I is a voluntary pilot program. Phase II is a mandatory reporting system DADS Phase I & II Phase Implementation Responsible Reporting Demand Reporting System Year Entities Requirement Response Frequency Design Type(s) In-house / BA, LSE, DP, Dispatchable, Semi - I 2010 Voluntary Excel PSE Controllable Annual Workbooks Third Party Software BA, LSE, DP, Dispatchable, Semi - II 2011 Mandatory Developer/ PSE Controllable Annual Web App
DADS Annual Reporting Cycle NERC has restructured the reporting timeframe and deliverable dates. •Semi-annual reporting will be implemented (versus the previously structured quarterly reports). The reporting periods are designed around summer and winter seasons—the summer reporting period will occur from April 1 st to September 30 th and the winter reporting period will occur from October 1 st to March 31 st . Data will be due to NERC approximately 2 1/2 months after the close of the reporting period. Phase I & II DADS Data Collection & Deliverable Schedule Date Action April 1 st – September 30 th Summer DADS reporting period December 15 th Summer DADS data due to NERC October 1 st – March 31 st Winter DADS reporting period June 15 th Winter DADS data due to NERC

Responsible Reporting Entities Responsible Entities will be required to maintain Demand Response data in DADS. A Responsible Entity is defined as a NERC Registered Entity that either dispatches a Demand Response Resource and/or administers a Demand Response Program, product or service. Responsible Entities for DADS data submittals are limited to: NERC Responsible Entities for DADS Data Function Name Responsible Entity Balancing Balancing Authority Distribution Distribution Provider Load - Serving Load - Serving Entity Purchasing-Selling Purchasing-Selling Entity
