Reliability Data Systems
Texas Reliability Entity, Inc. (Texas RE) assists the NERC Demand Response Data System (DADS), Transmission Availability Data System (TADS) and Generation Availability Data System (GADS) programs by training registered entities on how to submit required data through each system, reviewing the submitted data to ensure data completeness and accuracy, and providing assistance to NERC reporting. Texas RE also uses DADS, TADS and GADS data for reliability studies.
DADS – Demand Response Availability Data System
Demand Response helps ensure resource adequacy while providing operators with additional flexibility in maintain operating reliability. The DADS goal is to collect Demand Response data from events and to measure the actual performance to include system reliability. This analysis can provide the industry with a basis for projecting contributions of dispatchable and non-dispatchable Demand Response supporting forecast adequacy and operational reliability.

TADS – Transmission Availability Data System
The TADS collects simple transmission equipment availability data as well as detailed information of individual outage events in a common format. This provides a uniform approach to report and measure transmission availability, performance and other related transmission system reliability data. Analysis on TADS data at the regional and NERC level will provide information that may be used to improve Bulk Electrical System reliability.

GADS – Generation Availability Data System
GADS collects design, event and performance data of generation units for improving the performance of electric generating equipment. GADS data also helps those researching the vast amounts of information on power plant availability. The information is used to support equipment reliability and availability analysis and decision-making by GADS data users. Mandatory GADS reporting for conventional generating units 50MW and larger started January 1, 2012 and mandatory GADS reporting for conventional units smaller than 50MW but larger than 20MW will start January 1, 2013.
