The North American Electric Reliability Corporation (NERC) is phasing in mandatory quarterly GADS-W reporting requirements over three years for wind plants with an installed capacity over 75 MW and a commissioning date of January 1, 2005 or later. Plants with a capacity of over 200 MW started reporting on January 1, 2018 with 100 MW and 75 MW sites required to begin reporting on January 1, 2019 and January 1, 2020, respectively. 

The quarterly GADS-W reporting consists of submitting three reports: 

1. Sub-Group: consists mainly of site characteristics, location, and equipment information 
2. Performance: general site performance, including unavailability (forced, maintenance, or planned) for reasons outside of management control 
3. Component Outage: identifies the general area of reason for the loss of production using a list of component (system) codes to ensure consistency in reporting 

1979 ⎯  NERC assumes responsibility for collecting and analyzing generator availability data from the Edison Electric Institute’s (EEI) Prime Movers Committee. NERC, with support from the Electric Power Institute, restructures EEI’s Equipment Availability Data Reporting System to create the Generating Availability Data System (GADS). 

1990 ⎯  Congress passes the Clean Air Act Amendments of 1990. NERC uses the GADS database to provide the Energy Information Administration with a summary of forced and planned outages in the 1985−87 period. EPA uses the GADS data to set generator unit emission allocation values.

NERC's State of Reliability 2017 report is now available.

The report reviews past performance of the bulk power system, examines the state of system design, planning and operations, and the ongoing efforts by NERC and industry to continually improve system reliability and resiliency.

This independent review of bulk power system is based on analysis of data and metrics, which enables NERC to examine trends, identify potential risks to reliability, establish priorities and develop effective mitigation strategies.
