GADS Open Source Project’s mission is to promote openness, innovation and opportunity for collecting, analyzing, and reporting NERC GADS data. A completely open development process means that anyone can report bugs, request new features, or enhance the software.
GADS Open Source (GADS/OS) Data Entry and Analysis & Reporting give generating companies tools to take control of their mandatory GADS reporting to NERC and the various ISOs.
GADS/OS is a set of free and open source software tools and is licensed under the GNU General Public License Version 2 (GNU GPL or simply GPL) which is the most widely used free software license.
Solomon Associates has transferred their GADS NxL software, including the source code, to the GADS Open Source Project. Therefore, the project starts off with fully functional and exhaustively field tested software for you to download and install … all with no licensing or maintenance fees. Telephone and email support is provided at no cost.
The GADS/OS code base is in use at a wide range of generating companies from single plant sites to larger generating companies such as Northeast Utilities, ENMAX Energy, TVA, Calpine, Westar Energy, Luminant (TXU), Electricity Supply Board of Ireland, and Delta Electricity (Australia).
In addition, both the New York ISO and the ISO New England use the GADS/OS code base to administer their respective markets.
Our latest count shows that the GADS/OS code base is being used to collect and analyze data on more than 200 companies and 3,800 generating units both domestically and internationally. The user interface is available in both English and español.
GADS/OS Data Entry
GADS/OS Data Entry allows you to collect and report validated GADS performance data and event data (including outage, derating, non-curtailing, and reserve shutdown events plus special synchronous condensing and pumping operation event types) in standard formats required by NERC GADS and all major ISOs.
GADS data is collected for all major generating unit components—such as the boiler, nuclear reactor, heat recovery steam generator (HRSG), combustion turbine/jet engine, steam turbine, and generator—and other plant systems, subsystems, and components.
GADS/OS Analysis & Reporting
GADS/OS Analysis & Reporting allows you to calculate industry-standard performance measures for reliability, availability, and maintainability (RAM) assessments and key performance indicators (KPIs) using the GADS data for your generating units as the basis for those calculations.
Measures of generating unit performance — such as Availability Factor (AF), Equivalent Availability Factor (EAF), Forced Outage Rate (FOR), Equivalent Forced Outage Rate (EFOR), and Starting Reliability — have been defined, recorded, and utilized by the electric power industry for more than 50 years. The statistics can be calculated with and without OMC events from granularities as fine as hourly and daily to as coarse as yearly or longer.
Analysis & Reporting not only calculates these important standard measures, but also includes measures such as the Equivalent Demand Forced Outage Rate (EFORd) used in UCAP/ICAP calculations that have been developed to respond to the deregulated capacity and energy markets.
EFORd - Equivalent Demand Forced Outage Rate (EFORd) was added to IEEE Standard 762 in 2006. However, this equation has been used by the PJM Interconnection and the Canadian Electricity Association (CEA) for many years. It is not used by all ISO organizations as a measure of reliability and dependability. NERC GADS started calculating this number about 10 years ago and it was added to our software and other reports at that time. NERC GADS follows the IEEE 762 formula for calculating EFORd.
In addition to the 47 standard built-in reports, you can also add user-created reports built with SAP's Crystal Reports to the Analysis & Reporting reports list and run them from within the Program. Exporting to Excel is built into the Program and is always available to create simple, as well as easy, ad hoc reports.
