  6. Agenda (cont.) • Data release policies • Data applications • IEEE 762 Equations and their meanings (Metrics) • What are the equations calculated by GADS? • What are they trying to tell you? • Review of standard terms and equations used by the electric industry.

  7. What is NERC? • November 9,1965 Northeast black out • 30 million people affected • $100 million of economic losses • 1967 Federal Power Commission investigation. Recommends “council on power coordination.” • 1968 Regional groups formed NERC

  8. NERC Regional Entities (RE)

  9. NERC is the ERO

  10. Meeting Demand in Real Time Typical Daily Demand Curve Operating Reserves Peak Load Capacity: Instantaneous measure of electricity available at peak Intermediate Load Base Load Energy: Electricity Produced over Time

  11. Energy Policy Act of 2005 • Signed by President Bush in August 2005 • The reliability legislation amends Part II of the Federal Power Act to add a section 215 making reliability standards for the bulk- power system mandatory and enforceable. • Electric Reliability Organization (ERO) • Self-regulating reliability organization • Not a governmental agency or department • Same purpose: “To keep the lights on” but with more power to do so.

  12. Energy Policy Act of 2005 • “Bulk-power System” means the facilities and control systems necessary for operating an interconnected electric energy transmission network (or any portion thereof) and electric energy from generation facilities needed to maintain transmission system reliability. The term does not include facilities used in the local distribution of electric energy.

  13. 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

  14. What is NERC? • NERC is not a utility, association, institute, or a government organization. • NERC is a not-for-profit, international (US, Canada, and Mexico) corporation.

  15. Question & Answer

  16. What is GADS? G - Generating A - Availability D - Data S - System

  17. Generating Unit Database 1960’s - 1970’s North American Utility Database IEEE EEI Standard Terminology EPRI FPC

  18. GADS is Born! 1979 NERC EEI

  19. What is GADS? • Generating unit availability database • Critique the past • Monitor the present • Assess the future

  20. What is Meant by “Availability?” • GADS maintains a history of actual generation, potential generation and equipment outages. • Not interested in dispatch requirements or needs by the system! • ** If the unit is not available to produce 100% load, we want to know why!

  21. Critique the Past • Conduct special studies • High impact/low probability studies • Produce annual GADS publications • Generating Availability Report publication • GADS Brochure • Perform benchmarking services … and more

  22. Monitor the Present GADS Generator “C” Generator “D” Generator “B” Generator “A” Generator “E” 5,900+ generating units including international affiliates.

  23. GADS 2010 Data Reporting 5,963 units reported in 2010!

  24. Mandatory GADS in 2012

  25. Need for GADS Data TADS and DADS are already mandatory. GADS is the final step.

  26. GADS Task Force • Mandatory GADS submission discussed for many years. • In June 2010, the PC impaneled a task force to evaluate the status of GADS need for mandatory submission: • About 73% of the installed capacity (20 MW or larger) reports outage events to GADS. • Currently voluntary database • In 2011, the NERC RIS, PC and Board of Trustees recommended mandatory submission for conventional units (fossil, nuclear, combined cycle, etc).

  27. What are “Conventional Generating Units?” • The ten types of conventional generating units: • Fossil steam including fluidized bed design; • Nuclear; • Gas turbines/jet engines (simple cycle and others modes); • Internal combustion engines (diesel engines); • Hydro units/pumped storage; • Combined cycle blocks and their related components (gas turbines and steam turbines); • Cogeneration blocks and their related components (gas turbines and steam turbines); • Multi-boiler/multi-turbine units; • Geothermal units; and • Other miscellaneous conventional generating units (such as variable fuel – biomass, landfill gases, etc) used to generate electric power for the grid and similar in design and operation as the units shown above and as defined by the GADS Data Reporting Instructions.

  28. What are “Conventional Generating Units? • No Renewable!!!!!! • No Wind • No Solar • (At this time …)

  29. The Need For GADS Data • Historically: • Reliability Assessment reports and modeling • Loss-of-load Expectation studies and modeling • New Challenges • As the resource mix changes, NERC and its stakeholders will need to understand how the changes in resource performance translates into Planning Reserve Margins. • Understand the performance of existing and new resource technologies is essential to comprehending the reliability of the projected bulk power system in North America.

  30. The Need For GADS Data (cont’d) • Performance Analysis • Historical event data used to develop a severity metric risk measurement tool, establishing the bulk power system’s characteristic performance curve. • To calculate and measure both Event and Condition Driven risk, detailed event, and performance information • Monitoring the impact of transmission outages on generators and generator outages on transmission. • Power plant benchmarking, equipment analysis, design characteristics, projected performance, avoid long-term equipment/unit failures, etc.

  31. Justifications For Conventional Units • Nearly 300 GW are not reported GADS. • Nearly 50% of new units 2000-2008 do not report • Large amounts of hydro-pumped storage, combined cycle and gas turbines are missing. • These units are needed to analyze the reliability of the bulk power system.

  32. Recommendations – Process and Security • The task force recommends that GADS data be provided from all NERC Compliance Registry Generator Owners, following Section 1600, Requests for Data or Information under NERC’s Rules of Procedures. • GADS data confidentiality will be covered under NERC’s Rules of ProcedureSection 1500, Confidential Information.

  33. Recommendations - Unit Types • The ten types of conventional generating units will be required under the mandatory rule: • Fossil steam including fluidized bed design; Nuclear; Gas turbines/jet engines (simple cycle and others modes); Internal combustion engines (diesel engines); Hydro units/pumped storage; Combined cycle blocks and their related components (gas turbines and steam turbines); Cogeneration blocks and their related components (gas turbines and steam turbines); Multi-boiler/multi-turbine units; Geothermal units; and Other miscellaneous conventional generating units used to generate electric power for the grid as defined by the GADS Data Reporting Instructions.

  34. Recommendations – MW Sizes and When • Generator Owners shall report their GADS data to NERC as outlined in the GADS Data Reporting Instructions (Appendix III) for design, event and performance data for generating unit types listed above for units • 50 MW and larger starting January 1, 2012 and • 20 MW and larger starting January 1, 2013 • Generator Owners not listed on NERC’s Compliance Registry may report to GADS on a voluntary basis. • All small MW units invited but are voluntary.

  35. Multi-units on Meters Not Required Reporting to GADS – Treat as Normal Unit. 10 MW 10 MW 10 MW 10 MW 10 MW Meter Meter Meter Meter Meter Meter Reportable to GADS – Treat as “Miscellaneous Unit” 10 MW 10 MW 10 MW 10 MW 10 MW

  36. What is Meant by “MW Nameplate?” • “MW Nameplate” is calculated by multiplying the MVA recorded of the generator times the power factor. • For example, a 100 MVA unit with a .90 power factor would be a 90 MW unit. Generator Owners not listed on NERC’s Compliance Registry may report to GADS on a voluntary basis.

  37. Recommendations – Modify Reporting Software • There will be a one-time effort by non-reporting generating companies to modify their existing computer data collection program outputs into GADS required formats. The GADSTF believes that equipment outage data is already collected by plant personnel, although they may not adhere to GADS requirements.

  38. Recommendations - Uniformity • Uniformity of data collection format is essential. All GADS data shall be collected using the GADS Data Reporting Instructions. The Reporting Instructions will be updated annually and each reporting company will be required to follow the latest Reporting Instructions for the current year. All questions or needs for interpretation of the reporting instruction interpretations will be coordinated with NERC staff and the GADSTF. • Updates will follow the Section 1600 process.

  39. Recommendations – In-house Audits • In-house review of GADS data by the reporting generating company has always been strongly encouraged under voluntary data reporting. Each reporting generating company shall continue to be responsible for collecting, monitoring, updating and correcting their own GADS design, event, and performance data.

  40. Recommendations - Design • Design data is essential for many generating plant analyses. Generating companies will be asked to review and update their design data annually or as recommended by NERC staff using the design time-stamping process, but the updating will be voluntary. • The GADSTF leadership recommended that the design data requirement be nine (9) elements per unit, regardless of unit type.

  41. Recommendations - Design • The nine design data fields were chosen for two specific reasons: • Allowing GADS data to be matched with information collected in the Transmission Availability Data System (TADS). One goal of NERC is to allow the GADS and TADS databases to interact with each other. Certain data fields are needed to allow generating units to be located in areas where transmission lines are located. Specific fields allow that interaction. • Editing the event and performance data to insure the continued quality of information collected by GADS.

  42. Recommendations - Design • GADS utility code (assigned by GADS Services) • GADS unit code (assigned by the reporting company following the guidelines in Appendix C of the GADS Data Reporting Instructions.) • NERC Regional entity where the unit is located • Name of the unit • Commercial operating date • Type of generating unit (fossil, combined cycle, etc.) • MW size (nameplate) • State or province location of the unit. • Energy Information Administration (EIA) Plant number (US units only).

  43. Recommendations – Ownership/Retirement • NERC shall track ownership changes as generating units are sold to other operating companies. These changes will include the name of the new owners and the date of generating unit transfer. (Please note that GADS has been collecting ownership transfers for 10 years with no burden on reporters.) • Proposed or projected generating units retirement dates shall not be collected in GADS

  44. Question & Answer

  45. What’s new with GADS?

  46. Move to WebE-GADS

  47. Move to webE-GADS In August 2011, NERC signed a contract with OATI to collect GADS data starting in 2012.

  48. Move to webE-GADS • In preparation, GADS is moving away from old event and performance record formats (97/95) and accepting only the latest formats (07/05) starting this year. • All data sent to GADS should be year-to-date • January – September, not September only. • New formats allow cause code amplification codes (required as of January 1, 2011) for U1 events only.

  49. Move to webE-GADS • Beta testing of webE-GADS will begin during the first quarter of 2012. • Beta testers are needed. • Training on using webE-GADS will also be during the first quarter of 2012. • Once webE-GADS is up and operating, then no more data will be sent to gads@nerc.com or Mike Curley.
