NYISO Generating Availability Data System (GADS) Portal Tutorial

Generating Availability Data System (GADS) data is required by NYISO to determine the amount of capacity available for the Installed Capacity Market and to evaluate the reliability within the NY Control Area. The data is used to calculate the De-rating Factors for the NYISO Capacity Market. GADS data is used as an input into NYISO and the New York State Reliability Council's (NYSRC) Reliability Studies, specifically the Annual Installed Reserve Margin (IRM) Study for the New York Control Area and the NYCA Locational Capacity Requirements calculation. There are three types of data:  Design Data identifies the unit as an unique entity; Performance Data provides a summary of unit operation for a month; and Event Data consists of specific data for each event.

The NYISO GADS Portal accepts Performance and Event data.

The NYISO GADS portal enables Market Participants to upload standard GADS data files or to enter GADS Data directly via a user interface. MPs can edit/correct data errors identified during the submittal process. For example, users have the ability to correct a specific event start date or end date. The portal can also provide MPs with a standard 12 month ICAP EFORd report which captures a rolling 12-month period.

The NYISO GADS Portal was built by the GADS Open Source Project for the NYISO and can be accessed on the ICAP page of the NYISO website. 

In order to become an authorized user and submit GADS data through the portal, Market Participants will require a digital certificate and must be granted access to the portal. The GADS Administrator at the NYISO will provide access and each authorized user will have a User Name and password to access the Portal. The User Name will be the MIS User account name and the password entered will be their MIS password. Those MPs having an existing MIS account can request additional access to the GADS portal through the NYISO’s GADS administrator

This Portal training is meant to provide a high level introduction to the NYISO GADS Portal as part of the October 2014 deployment. This presentation assumes previous knowledge of GADS data and familiarity with the NYISO requirements.

For more comprehensive information on the NYISO GADS Data requirements please refer to the NYISO Installed Capacity Manual.

For more detailed information regarding the entire functionality of the NYISO GADS Portal, refer to the GADS Portal User’s Guide.
