Northeast Power Coordinating Council • NPCC • One million • square miles • 54 million people • 50% US • 50% Canadian • Represents 70% • of Canadian Load http://www.npcc.org/ November 18, 2004
NPCC Statistics Projected 2004 Summer Coincident Peak Demand 104,520 MW Projected 2004 Summer Net Capacity 143,670 MW Historically, the summer peak loads and temperatures between New England and New York can have a high degree of correlation; there is also some potential for the Ontario summer peak demand to be coincident. The Canadian Provinces of Québec and the Maritimes experience their highest electricity demand in the winter. November 18, 2004
NPCC Basic Criteria for Design and OperationOf Interconnected Power Systems 3.0 Resource Adequacy - Design Criteria Each Area’s probability (or risk) of disconnecting any firm load due to resource deficiencies shall be, on average, not more than once in ten years. Compliance with this criteria shall be evaluated probabilistically, such that the loss of load expectation [LOLE] of disconnecting firm load due to resource deficiencies shall be, on average, no more than 0.1 day per year. http://www.npcc.org/PublicFiles/Reliability/CriteriaGuidesProcedures/A-02.pdf November 18, 2004
NPCC Basic Criteria for Design and OperationOf Interconnected Power Systems 3.0 Resource Adequacy - Design Criteria This evaluation shall make due allowance for demand uncertainty, scheduled outages and deratings, forced outages and deratings, assistance over interconnections with neighboring Areas and Regions, transmission transfer capabilities, and capacity and/or load relief from available operating procedures. http://www.npcc.org/PublicFiles/Reliability/CriteriaGuidesProcedures/A-02.pdf November 18, 2004
NPCC Guidelines for Area Review ofResource Adequacy Purpose The purpose of the presentation associated with a resource adequacy review is to ascertain that each Area's proposed resources are in accordance with the NPCC Basic Criteria for Design and Operation of Interconnected Power Systems (Document A-2). By such a presentation, the Task Force will satisfy itself that the proposed resources of each NPCC Area will meet the NPCC Resource Adequacy - Design Criteria (as defined in Section 3.0 of NPCC Document A-2) over the time period under consideration. This review by the Task Force on Coordination of Planning does not replace Area and/or company responsibility to assess their systems in conformity with the NPCC Basic Criteria. http://www.npcc.org/PublicFiles/Reliability/CriteriaGuidesProcedures/B-08.pdf November 18, 2004
NPCC Triennial Reviews of Area Resource Adequacy Objective: As part of the NPCC Reliability Assessment Program, the Task Force on Coordination of Planning is charged, on an ongoing basis, with conducting reviews of resource adequacy of each Area of NPCC, in accordance with NPCC Document B-8, Guidelines for Area Review of Resource Adequacy. http://www.npcc.org/resourceAdequacyReviews.asp?Folder=CurrentYear November 18, 2004

NERC Reliability Assessments NERC issues regular assessments of the reliability of North American bulk electric systems. Ten-Year Reliability Assessments - Each year NERC prepares an assessment of the adequacy of the bulk electric system in the United States and Canada for a ten-year period. The report assesses projected electricity supply and demand, reviews transmission system adequacy, and discusses key issues and trends that could affect reliability. Summer and Winter Assessments - These annual reports assess the adequacy of electricity supplies in the United States and Canada for the upcoming summer and winter peak demand periods. Special Assessments - Special reliability assessments are conducted on a regional, interregional, or interconnection-wide basis as conditions warrant. http://www.nerc.com/~filez/rasreports.html November 18, 2004
NERC Resource and Transmission Adequacy Recommendations The NERC Planning Committee (PC) approved the Resource and Transmission Adequacy Task Force’s (RTATF) report, “Resource and Transmission Adequacy Recommendations,” via mail ballot on May 27, 2004. The NERC Board of Trustees, at its June 15, 2004 meeting, also approved the RTATF report and associated recommendations for implementation. Subsequently, the PC approved the action plans related to the resource adequacy recommendations of the RTATF report at its July 20, 2004 meeting. Those action plans charged the RIS with the development and submittal of a Standard Authorization Request (SAR) on resource adequacy that recognized the elements of resource recommendations 1, 2, 3, and 4 of the RTATF report. http://www.nerc.com/~filez/rtatf.html November 18, 2004
NERC Gas/Electric Interdependency Task Force The PC and the NERC board gave similar approvals to the Gas/Electricity Interdependency Task Force’s (GEITF) “Gas/Electricity Interdependencies and Recommendations” report at the same meetings. The PC also approved the implementation plan for the GEITF recommendations at its July 20, 2004 meeting. Recommendation 4 charged the RIS with developing a SAR that related fuel infrastructure reliability to resource adequacy. RIS has developed a SAR that incorporates the required elements of the RTATF and GEITF reports. http://www.nerc.com/~filez/geitf.html November 18, 2004
Draft NERC SAR on Resource Adequacy 1. a) Each NERC Regional Reliability Council (Region) to establish a resource adequacy criterion (or criteria) based on some metric (e.g., LOLE, LOLP, etc.), consistent with applicable state/province or multi-state/province resource adequacy criteria or requirements. The adequacy criteria should take into account operable capacity situations and reflect the impact of expected transmission constraints, fuel deliverability, environmental restrictions, and other relevant factors. The state(s), province(s), RTO/ISO(s), generation reserve sharing pool(s) and/or other appropriate entity(ies) should establish resource adequacy requirements so as to comply with the resource adequacy criterion (or criteria) of the Region. The Region or subregions should establish assessment methodologies to determine whether the adequacy criteria are met. November 18, 2004
Draft NERC SAR on Resource Adequacy 1. b) Each Region should be required to demonstrate periodically, through analysis, that Regional resource adequacy requirements (such as reserve margins, capacity margins, etc.) satisfy the applicable resource adequacy criteria (such as LOLE, LOLP, etc.). As a part of the demonstration, each Region should describe the expected resource capacity characteristics for the study period and demonstrate that possible fuel supply interruptions have no adverse impact on system reliability. Each Region should also describe available mechanisms to mitigate the impacts of fuel interruption(s) on its ability to serve load reliably. Other factors such as expected transmission constraints and/or environmental restrictions that may impact the Region’s resource adequacy should be examined. The demonstrations should include analyses supporting all critical assumptions. November 18, 2004
Draft NERC SAR on Resource Adequacy 2. The results of all Regional resource adequacy assessments, whether performed by NERC or the Regions, should be made public with the understanding that some data which supports the assessment may be confidential and may not be made public. The Region will aggregate the supply/demand data within the Region and report an aggregate number, not individual electric utility supply/demand data if that data is not available in other public forums. November 18, 2004
Draft NERC SAR on Resource Adequacy 3. NERC should perform periodic audits of the Regional resource adequacy assessment processes. Such audits should validate the compliance of the Regional adequacy requirements with the resource adequacy criteria and may include the performance of independent analysis by NERC. Such audits should also confirm the consistent application of standard resource adequacy assessment methodologies, including appropriate Regional variations. November 18, 2004
Draft NERC SAR on Resource Adequacy 4. NERC, in conjunction with the Regions, should conduct periodic reviews of the respective Regional resource adequacy criteria and their methodologies for general consistency, interdependency and/or impact on adjacent Regions, the treatment of contract considerations, and the deliverability of resources to load.
