The Future of GADS – How Availability Data Can Enhance Long-Term Reliability Assessment Austin, TX November 7, 2011
The GADS Data Monster 2 RELIABILITY | ACCOUNTABILITY
The GADS Databases • Design – equipment descriptions such as manufacturers, number of BFP, steam turbine MW rating, etc. • Performance – summaries of generation produced, fuels units, start ups, etc. • Event – description of equipment failures such as when the event started/ended, type of outage (forced, maintenance, planned), etc. 3 RELIABILITY | ACCOUNTABILITY
Performance Records Include • Unit Identification • Month/year of report • MW generated • Various MW rating of the unit (Gross and Net Maximum and dependable capacities) Any non-equipment loss from ambient conditions. • Summary of various active hours (SH, RSH, Pumping hours, synchronous condensing) • Summary of various outage hours (FO, MO, PO) • Fuels burned 4 RELIABILITY | ACCOUNTABILITY
Event Records Include • Unit identification • Start/end of events • Type of event • Reason for the event Cause code, and Description of outage or derate 5 RELIABILITY | ACCOUNTABILITY
Mandatory GADS in 2012 6 RELIABILITY | ACCOUNTABILITY
Need for GADS Data TADS and DADS are already mandatory. GADS is the final step. 7 RELIABILITY | ACCOUNTABILITY
Summary of Mandatory Report • Mandatory under Section 1600 and 1500 of the NERC Rules of Procedure . • Conventional (no renewable) units only 50 MW+ starting January 1, 2012 20 MW+ starting January 1, 2013 • Modification of in-house software only once. • Uniformity in collection using GADS as authority. • In-house audits of own data. • Design data limited to 9 elements only. • NERC tracks ownership of units • No future retirement dates in GADS 8 RELIABILITY | ACCOUNTABILITY
Question & Answer 9 RELIABILITY | ACCOUNTABILITY
What’s new with GADS? 10 RELIABILITY | ACCOUNTABILITY
Move to WebE-GADS 11 RELIABILITY | ACCOUNTABILITY
Move to webE-GADS In August 2011, NERC signed a contract with OATI to collect GADS data starting in 2012. 12 RELIABILITY | ACCOUNTABILITY
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 . 13 RELIABILITY | ACCOUNTABILITY
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. 14 RELIABILITY | ACCOUNTABILITY
Question & Answer 15 RELIABILITY | ACCOUNTABILITY
Continuing Projects • Addition of wind generators and solar to GADS Working group formed to determine design, event, cause codes, etc. for data collection. Voluntary data collection at this point. 16 RELIABILITY | ACCOUNTABILITY
Wind Turbine Groups zzz Wind Turbine Group Groups report the following site data: Associated Plant Identifier Turbine Group ID Turbine Group Name NERC Utility Code NERC Unit Code Installed Capacity in MW Auxiliary Capacity Commercial Date Nearest City, State Location Longitude and Latitude Elevation Wind Regime (topography) SCADA Type SCADA Manufacturer SCADA Model 17 RELIABILITY | ACCOUNTABILITY
What is pc-GAR? • Unique software product to allow access to the data collected in the GADS database. • It reports equipment outage information for the purpose of improving electric power output. pc-G.A.R 18 RELIABILITY | ACCOUNTABILITY
Uses of pc-GAR • Benchmarking generating units • Class averages • Q&A from public utility commissions, other groups • Comparing Summer and Winter periods • Locating top causes of outages (F, M, or P) Outages or derates • Many more reports, distributions, averages, etc. • Reports can be made into graphs • Outputs in screen views, prints, or CSV. 19 RELIABILITY | ACCOUNTABILITY

Background Information 21 RELIABILITY | ACCOUNTABILITY
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). 22 RELIABILITY | ACCOUNTABILITY
What are “Conventional Generating Units? • No Renewable!!!!!! No Wind No Solar (At this time …) 23 RELIABILITY | ACCOUNTABILITY
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. 24 RELIABILITY | ACCOUNTABILITY
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 Procedure Section 1500, Confidential Information. 25 RELIABILITY | ACCOUNTABILITY
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. 26 RELIABILITY | ACCOUNTABILITY
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. 27 RELIABILITY | ACCOUNTABILITY
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. 28 RELIABILITY | ACCOUNTABILITY
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 Reportable to GADS – Treat as “Miscellaneous Unit” 10 MW 10 MW 10 MW 10 MW 10 MW Meter 29 RELIABILITY | ACCOUNTABILITY
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. 30 RELIABILITY | ACCOUNTABILITY
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. 31 RELIABILITY | ACCOUNTABILITY
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. 32 RELIABILITY | ACCOUNTABILITY
