Misoperation Information Data Analysis System (MIDAS)

MIDAS is a web-based system used to collect protection system misoperation data in accordance with the NERC Rules of Procedure, Section 1600 Data Request in a common format. This information is used to assess protection system performance, identify trends, develop metrics, and improve bulk power system reliability. 

Applicable To:

MIDAS submission is mandatory for all U.S. Transmission Owners, Generator Owners and Distribution Providers who are on the NERC Compliance Registry. Non-U.S. Transmission Owners, Generator Owners and Distribution Providers should provide data in accordance with the legislation, laws, regulations, rules or orders of their applicable governmental authority. 

Frequency: 

Applicable entities are required to report data on a quarterly basis within 60 days of the end of each quarter.

How To Report Data:

Definitions of operations data to be submitted, reporting deadlines, and instructions and templates for MIDAS are available on the NERC Protection System Misoperations website. MRO encourages entities to complete the voluntary data fields within MIDAS, above and beyond the data required to be reported.

Data is collected in the NERC MIDAS Portal via the ERO Portal. The MIDAS Portal User Guide is available at the NERC Protection System Misoperations website.

MRO’s Role:

MRO assists NERC staff in initial registration of users and organizations, as well as overseeing data entry. At the end of each reporting period, MRO staff ensure that all MIDAS data has been submitted by each Functional Entity. MRO performs data validation to ensure content is consistent and accurate.

NERC provides a public report with MIDAS data aggregated for each region.
