Through scheduled data submissions from registered entities, Texas RE monitors and reports the performance metrics for ERCOT region compliance with certain NERC Reliability Standards. The
2019 ERO Enterprise Periodic Data Submittals Schedule and the
2018 Consolidated ERO Enterprise Periodic Data Submittals Schedule are posted on the NERC website to provide registered entities a consistent periodic data submittal schedule throughout the ERO Enterprise by eliminating the regional schedule variations.
The NERC ERO Reliability Assessment and Performance Analysis (ERO-RAPA) group reviews protection and control system misoperations that are associated with a significant percentage of BES disturbances. Reducing the risk to reliability from relay and control system misoperations requires consistent collection of misoperation information by Regional Entities, along with systematic analysis and correction of the underlying causes of preventable misoperations.
NERC Reliability Standard PRC-004-5(i) requires Transmission Owners, Generator Owners, and Distribution Providers to analyze Protection System misoperations, and to develop and implement Corrective Action Plans.
With the implementation of PRC-004-5(i), reporting of Protection System misoperations is covered by a Section 1600 data request. The NERC Misoperation Information Data Analysis System (MIDAS) is the portal for registered entities to upload Protection System misoperation data to NERC and the Regional Entities.
A reporting template is posted on the
MIDAS submission schedule:
|Reporting Quarter ||MIDAS Report Submission Period |
|Q1||April 1 - May 30|
|Q2||July 1 - August 29|
|Q3||October 1 - November 29|
|Q4||January 1 - March 1|
PRC-002-2 R12, enforceable October 1, 2016, requires that Transmission Owners and Generator Owners shall, within 90 calendar days of the discovery of a failure of the recording capability for any Sequence Event Recording (SER), Fault Recording (FR), or Dynamic Disturbance Recording, (DDR) data either:
- Restore the recording capability, or
- Submit a Corrective Action Plan (CAP) to the Regional Entity and implement it.
To facilitate uniformity in the submission process, Texas RE has created a form for submission of Corrective Action Plans to Texas RE Compliance. This form will be kept on file at Texas RE, however the registered entity will still be required to maintain all relevant evidence, including the CAP, per M12. Please note that no CAP submission is necessary if recording capability is restored within 90 calendar days. If it is determined that the recording capability cannot be restored within the 90 calendar days, submission of CAP must be made within 90 calendar days of discovery.
If a registered entity identifies a need to submit a Corrective Action Plan to Texas RE, please send notification to Texas RE at Texas RE Compliance. Upon receiving notification from the registered entity, Texas RE will work with the registered entity to accommodate submission of the Corrective Action Plan through Texas RE’s Extranet site.
EOP-008-2 R8 requires Reliability Coordinators, Balancing Authorities, and Transmission Operators that have experienced a loss of its primary or backup functionality and that anticipate that the loss of primary or backup functionality will last for more than six calendar months to provide a plan to its Regional Entity within six calendar months of the date when the functionality is lost, showing how it will re-establish primary or backup functionality.
To facilitate uniformity in the submission process, Texas RE has created the form posted below for submission of plans to Texas RE Compliance. This form will be kept on file at Texas RE.
If a registered entity identifies a need to submit a plan to Texas RE, please send notification to Texas RE at Texas RE Compliance. Upon receiving notification from the registered entity, Texas RE will work with the registered entity to accommodate submission of the plan through Texas RE’s Extranet site.
FAC-003-4, PRC-016-1, and PRC-023-4 Periodic Data Submittals
Texas RE requests Period Data Submittals from applicable entities for FAC-003-4, PRC-016-1, and PRC-023-4 in accordance with the ERO Periodic Data Submittal Schedule. The data submittal forms utilized by Texas RE for these Periodic Data Submittals are included below.
For applicable registered entities that do not own Facilities applicable to the Reliability Standards and Requirements subject to the Periodic Data Submittal requests, Texas RE accepts one-time attestations. Registered entities that provide one-time attestations will not receive data submittal requests for these Reliability Standards and Requirements unless warranted by facts and circumstances. However, if conditions change that impact the registered entity’s applicability to a Reliability Standard and Requirement subject to a Periodic Data Submittal for which a one-time attestation has been submitted, it is expected that the registered entity notify Texas RE Compliance of the change so the registered entity can begin meeting the reporting requirements for the applicable Reliability Standard and Requirement. The one-time attestation forms for these Reliability Standards and Requirements are included below.
