About NERC

  • Develop & enforce reliability standards
  • Analyze system outages and near-misses

& recommend improved practices

  • Assess current and future reliability

International regulatory authority for electric reliability in North America

NERC & Demand Response

  • Demand Response is an important component in the
  • verall 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
  • ption 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

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

  • 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 Annual Reporting Cycle

Phase I & II DADS Data Collection & Deliverable Schedule Date Action April 1st – September 30th Summer DADS reporting period December 15th Summer DADS data due to NERC October 1st – March 31st Winter DADS reporting period June 15th Winter DADS data due to NERC

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 1st to September 30th and the winter reporting period will occur from October 1st to March 31st. Data will be due to NERC approximately 2 1/2 months after the close of the reporting period.

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

Why the “Duplicative” Reporting?

  • External Relationships
  • A single Demand Response resource can be used in multiple

programs for different Reporting Entities

Overview of Data to be Collected

  • Demand Response Program Criteria
  • DADS requires data for all Demand Response Programs

currently in effect. However, Responsible Entities are only required to register and submit data on Demand Response Programs if: 1) The Demand Response Program has been commercially in- service for more than 12 months; or 2) The Demand Response Program has enrolled 10 MW or more of combined Demand Response Resources.

  • Serves to not discourage small scale Demand Response

deployment and to encourage the development of pilot Demand Response.

  • Energy, Capacity, Reserve, Regulation

Overview of Data to be Collected

  • Confidentiality of Submitted Data
  • Any data submitted that is classified as confidential shall be managed in

accordance with NERC’s treatment of confidential information as described in Section 1500 of the Rules of Procedure. Confidential data will not be accessible by others except the Responsible Entity that submitted that data and NERC staff, who will be responsible for its analysis; however, aggregate data may be used for metrics and presented to third parties as necessary or appropriate.

  • DADS data may be classified as:
  • Confidential Business and Market Information
  • Critical Energy Infrastructure Information
  • Non-Confidential
  • The following data will be classified as confidential when deemed so by a

Responsible Entity.

  • Enrollment Data (Number of Registered Resources and Registered MWs)
  • All Reliability Event/Market Participation/Ancillary Product Data

DADS is intended to serve as a valuable tool, not only for reliability and resource adequacy analysis, but for research outside of NERC.

slide-25
SLIDE 25

Other Important Notes

  • All data is aggregated
  • No single demand resource identified
  • NERC is working on developing a procedure to minimize

reporting burden

  • If the entity does not have qualifying demand response programs
  • If the entity’s entire portfolio of resources are included in another

entity’s program

  • Phase I voluntary submission dates are flexible!
  • The goal is to learn and understand the reporting procedure,

which programs should/should not be reported, and develop enhancements for Phase II

DADS Status & Next Steps

  • Status:
  • PHASE I in progress (Voluntary Data)
  • Letter to industry participants confirming

restructured data submission requirements

  • Next Steps
  • Coordinate mandatory requirements
