The Generation Availability Data System (GADS) is a series of databases used to collect design, event and performance data for electric generating equipment. The data collected is used during assessment of generation resources and supports equipment availability analyses and other decision-making processes in the industry.
NERC-registered Generator Owners (GO) with unit nameplates of 20MW and above are required to report through webGADS. Smaller units are encouraged to report voluntarily.
NERC-registered Generator Operators (GOP) with wind plants of 75 MW or greater of total installed capacity, commissioned by January 1, 2005 or later, report similar data using the ERO Portal’s GADS Wind Data Submission Site. GADS Wind Turbine Generation Data Reporting Instructions detail the procedure and format to follow when reporting data using the ERO Portal.
Both GOs and GOPs submit data quarterly – due no later than 6 weeks after the end of each quarter.
MRO staff primarily function as webGADS administrators. MRO assists NERC staff in initial registration of users and organizations, as well as overseeing data entry prior to aggregation at the NERC level. At the end of each reporting period, MRO staff ensure that all webGADS data forms have been completed by each Functional Entity. These forms include not only unit, performance, and event data, but also a review of each company’s contacts. MRO performs data validation to ensure any flagged content is revised by the end of the regional reporting period. Upon conclusion of the Regional Entity data review, NERC staff will begin their aggregation and review of the reporting period’s data.
