Generating Availability Data System (GADS)

​​

The electric industry initiated GADS in 1982 to expand data collection activities that began in 1963. Today, NERC’s GADS maintains operating information on conventional generating units, wind plants, and solar plants.


Through GADS, NERC collects information about the performance of electric generating equipment and supports equipment availability analyses.


GADS reporting is mandatory for NERC-registered entities with conventional generating units that are 20 MW or more, wind plants with a total installed capacity of 75 MW or more and a commercial operation date of January 1, 2005, or later. Effective January 1, 2024, solar plants with a total installed capacity of 100 MW or more, regardless of interconnection, are required to report. Effective January 1, 2025, solar plants with a total installed capacity of 20 MW or more, regardless of interconnection, are required to report.


Access to GADS for reporting is limited to NERC-registered entities and requires a webCARES digital certificate. See the NERC OATI WebPortal User Registration Form for details.

Design Data is currently required for fossil steam, fluidized bed, gas turbine, hydro/pumped storage, and reciprocating internal combustion engine units. The ability to report Event and Performance data are not available until unit design data has been reported for all units associated with a company.


Combined cycle and cogen unit design data reporting is expected to be available in July 2024.​​


Note: Design data will not be required for miscellaneous, nuclear, geothermal, or multi-boiler/multi-turbine units.
