NERC Generating Availability Data System (GADS): pc-GAR

The pc-GAR family of products, the automated personal computer (pc-) version of NERC's Generating Availability Report, (GAR) is ready for your use. The pc-GAR family expands the usefulness of this NERC report by placing you in control of the data retrieval and report writing process. It is the easiest and fastest way to use reliability information from more than 5,800 generating units reporting to NERC's Generating Availability Data System (GADS).

pc-GAR is a NERC-developed application that lets users take advantage of the wealth of information in the Generating Availability Data System (GADS). pc-GAR is an easy-to-use program for querying the GADS database and producing reports and table presentations based on the results right in your own office! pc-GAR employs the latest Windows-based technology such as pull-down menus and dialogue boxes to help you specify data selection and analysis parameters. With pc-GAR, you can examine the operational histories of your generating units, compare these histories against similar groups of units, examine component and cause code availability, and much more.

Power generators will have access to detailed data on their units' operations as well as summary information on groups of units. Other power generators can access their own unit-specific data, but not others.

pc-GAR Applications

  • access to information on your own individual units
  • locating similarly equipped generating units
  • comparing the performance of manufacturers
  • conducting general trend analyses

Please note that pc-GAR products are only available to GADS-contributing entities (electricity generators that report event, performance, and design data on an annual basis).  For a complete pricing schedule for NERC GADS products and services go to:

Generators/operators who do not report data to GADS will not have access to pc-GAR or any GADS reports. This ruling was established by the NERC Planning Committee in November 2000.
