4.1.4 Who Must Report

For U.S. TO’s, providing 2015 TADS data is mandatory for all TO’s on the NERC Compliance Registry. For 2015 Non-Automatic outage TADS data, non-U.S. TO’s on the NERC Compliance Registry who are also NERC members are required to supply it. As NERC members, they must comply with NERC’s Rules of Procedure, and because Phase II TADS data was requested in accordance with Section 1600, these non-U.S. TO’s must provide Phase II TADS data. However, NERC, through the Regional Entities, will also be requesting TADS data from non-U.S. TO’s on the NERC Compliance Registry. Section 1.10 provides additional information about the registry.

The following describe reporting requirements for different TO situations:


  1. Non-reporting TO’s that do not own any TADS Elements as of the date Form 1.1 is submitted (in December prior to the reporting calendar year – e.g., for 2015 calendar year reporting, Form 1.1 would be submitted in December 2014) are not required to report any other TADS data for the reporting calendar year even if they subsequently become owners of TADS Elements during that calendar year. However, a TO may voluntarily report data for the year that the TADS Elements are added.

  2. TO’s that register during a reporting calendar year are not subject to any TADS reporting requirements until the next calendar year. However, a TO may voluntarily report data for the year that it first becomes newly registered.

  3. A non-reporting TO that becomes unregistered during a calendar year is no longer subject to any TADS reporting requirements. However, if a reporting TO becomes unregistered during a reporting calendar year, it has either (i) retired all its TADS Elements or (ii) sold all its TADS Elements. In case (ii), the new TO shall assume the reporting obligation of the unregistered TO for the entire calendar year. This will ensure that all TADS Elements continue to have their data reported.



5.1. 5 Data Confidentiality

Under NERC’s confidentiality policy (Section 1500 of NERC’s Rules of Procedures), the entity claiming that information is confidential must state the category under which such information qualifies as confidential.


For practicality, data on certain forms has been judged as confidential because it contains critical energy infrastructure information (CEII) while other information is not confidential. A TO may change NERC’s default confidentiality classification in Table 1.5 by sending an e-mail to the NERC project manager – see the TADS Project Manager’s contact information in a Regional Entity and NERC TADS Contacts document that is posted at:

http://www.nerc.com/comm/PC/Pages/Transmission-Availability-Data-System-Working-Group-(TADSWG)-2013.aspx.


If a TO wants non-confidential data to be made confidential, the TO must indicate the category or categories defined in Section 1501 in which the data falls. See Section 1502 of the Rules of Procedure.

CEII is defined by Federal Energy Regulatory Commission (FERC) rules as follows:2



  1. Critical energy infrastructure information means specific engineering, vulnerability, or detailed design information about proposed or existing critical infrastructure that:

  1. Relates details about the production, generation, transportation, transmission, or distribution of energy;

  2. Could be useful to a person in planning an attack on critical infrastructure;

  3. Is exempt from mandatory disclosure under the Freedom of Information Act, 5 U.S.C. 552; and

  4. Does not simply give the general location of the critical infrastructure.

  1. (2) Critical infrastructure means existing and proposed systems and assets, whether physical or virtual, the incapacity or destruction of which would negatively affect security, economic security, public health or safety, or any combination of those matters.

Table 1.5 below summarizes our judgments on confidential information for each form:

As described in the Section 2.4.7 of the Phase I Report, regional and NERC annual public performance reports will show aggregated confidential information of many TO’s. In doing so, no particular TO’s data should be identifiable. However, these reports will not inadvertently release confidential information by the display of regional or NERC information from which a TO’s confidential information could be ascertained. For example, if the TO in a region is the only owner of assets in a particular Voltage Class, the metrics on that data would not be released if the TO’s name and its confidential information could be identified, unless the TO agrees to such a release. If we find that a particular TO’s metrics could be identified in a report, the TO will be asked to voluntarily allow reporting of its metrics while keeping other aspects of its data confidential. By “other aspects of its data”, other TADS data, such the date of an AC Circuit Sustained Outage or the AC Substations that identify the outaged circuit, are meant. Those inputs allow an RE or NERC to determine whether outages of different TO’s are a single Event. These requests will be addressed on a case-by-case basis.



1.5.1 Transmitting TADS Data Securely by E-mail

The webTADS data entry software described in Section 1.9 will transmit data securely into webTADS. Therefore, e-mail will primarily be used by TO’s to transmit corrections to data that must be entered by a Regional Entity (RE) coordinator or NERC staff when webTADS data entry is closed to TO’s. If an entity (TO, RE, or NERC) has its own critical infrastructure protection (CIP) procedure for transmitting confidential information by e-mail, that procedure should be followed. If those procedures are not yet developed, the following process should be followed:



  1. Password-protect the document to be transmitted, and send it via e-mail to the recipient. Do not include the password in this e-mail.

  2. In a second separate e-mail, send the password to the recipient of the document.
