Misoperation Information Data Analysis System 
Misoperation Information Data Analysis System (MIDAS) efforts began in 2014 in accordance with the NERC Rules of Procedure Section 1600 Data Request. MIDAS is a web based system used to report and collect protection system misoperation data, in a common format.

Instructions and examples are available at the NERC Protection System Misoperations website which defines operation and misoperation information to be reported in MIDAS.

NERC uses the information available in MIDAS to develop protection system misoperation metrics related to Bulk Electric System Element outages. NERC also provides a public report with MIDAS data aggregated for each Region.

Reporting
Provision of MIDAS data 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. 

Statistical data associated with misoperations shall be collected in accordance with the NERC Rules of Procedure, Section 1600 data request. MRO encourages completion of voluntary data fields within MIDAS, above and beyond the mandatory data to be reported. For additional information, refer to the instructions provided on 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.

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.
