Welcome to the GADS Open Source Project Support Blog

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.

The current version of GADS Open Source™ can be found on CodePlex.

You can download the installable Data Entry and Analysis & Reporting programs for the GADS Open Source Project directly from the CodePlex website ( http://gadsos.CodePlex.com/ ) without needing to be registered or logged in. Just go to the Downloads tab for the project and click on the "Download" link. Installation instructions are also listed on this tab.

As change comes to the power generation industry, an engineered approach to reliability is more important than ever

by ronfluegge 1. June 2010 15:08

When U.S. electric utilities began deregulating in the 1990s, they reduced their focus on internal RAM monitoring and analysis in an effort to cut costs that did not contribute directly to the bottom line. Today, a new set of changes, from the entry of renewable energy sources to the prospect of carbon trading, is on the verge of transforming the industry once again. This time, however, the changes promise to highlight – and heighten – the importance of an engineered approach to reliability and maintenance.

Based on abrupt changes in plant utilization observed in Europe after the introduction of carbon trading in 2005, we can anticipate similar upheaval at U.S. plants as renewables and potential cap-and-trade legislation transform the usage profile of generating units. To mitigate the impact of these changes, operators will have to reassess the best way to utilize and maintain their units for optimal performance. In this article, we take a look at some of the expected changes and how operators can prepare for them.

All data in the following analysis come from Solomon Associates’ proprietary database, utilized in our company’s worldwide benchmarking and consulting services. For this article, we studied data from participating power generation units from 2005-2008, concentrating on U.S., Canadian and European generation, further segregated into coal-fueled steam and gas-fired combined-cycle technologies. Cogeneration combined-cycle gas turbine (CCGT) units that exported more than 20 percent of their total energy in steam were excluded in favor of units whose production was primarily electricity for comparison.
