The Transmission Operator does not schedule sufficient reactive resources as necessary to avoid violating an IROL. R3 Real-time Operations, Same-day Operations, and Operational Planning High N/A N/A The Transmission Operator does not operate or direct any real-time operation of devices as necessary to avoid violating an SOL.

R6 Operations Planning Lower The Transmission Operator does not provide either the technical justification or timeframe for changing generator step-up tap settings. N/A N/A The Transmission Operator does not provide the technical justification and the timeframe for changing generator step-up tap settings.
M.E.A.13 Each Transmission Operator shall have and provide upon request, evidence that it provided the voltage schedules to the Generator Operator. Dated spreadsheets, reports, voice recordings, or other documentation containing the voltage schedule including set points, tolerance bands, and specified periods as required in Requirement E.A.13 are acceptable as evidence. M.E.A.14 The Transmission Operator shall have and provide upon request, evidence that it provided one of the voltage schedule reference points in Requirement E.A.14 for each generation resource in its Area to the Generator Operator. Dated letters, or other documentation that contains notification to the Generator Operator of the voltage schedule reference point for each generation resource are acceptable as evidence. M.E.A.1 The Transmission Operator shall have and provide upon request, evidence that within 30 calendar days of request by its Generator Operator it provided data to support development of the voltage set point conversion methodology. Dated reports, spreadsheets, or other documentation are acceptable as evidence. Violation Severity Levels E # Lower VSL Moderate VSL High VSL Severe VSL E.A.13 For the specified period, the Transmission Operator did not issue one of the voltage schedules listed in E.A.13 to at least one generation resource but less than or equal to 5% of the generation resources that are on-line and part of the BES in the Transmission Operator Area. For the specified period, the Transmission Operator did not issue one of the voltage schedules listed in E.A.13 to more than 5% but less than or equal to 10% of the generation resources that are on-line and part of the BES in the Transmission Operator Area. For the specified period, the Transmission Operator did not issue one of the voltage schedules listed in E.A.13 to more than 10% but less than or equal to 15% of the generation resources that are on-line and part of the BES in the Transmission Operator Area. For the specified period, the Transmission Operator did not issue one of the voltage schedules listed in E.A.13 to more than 15% of the generation resources that are and part of the BES in the Transmission Operator Area.
