1 A. Introduction 1. FRCC Regional Generator Performance During, Frequency and Voltage Excursions. 2. Number: 3. Purpose: To ensure that generators remain connected to the electrical grid during voltage and frequency excursions. 4. Applicability: Owner of generation (Generator Owner (GO)), that is located within the FRCC Region, operates synchronously to the Bulk Electric System, and has a nameplate rating(s) > 20 MVA or a generating plant/facility > 75 MVA (gross aggregate nameplate rating). 5. Effective Date: TBD B. Requirements: R1. GOs shall set synchronous generator protection and controls so that generator protection and controls will not initiate generator tripping or islanding, for conditions that are within the time durations specified in [Risk Factor: High], [ Time Horizon: Long-term Planning]. R2. GOs shall provide documentation of generator protection and control settings to the FRCC within 30 days of a specific FRCC documentation request.[risk Factor: Lower], [ Time Horizon: Long-term Planning] R3. Individual generators can be exempted from requirement R1 of this standard if an exemption is approved by the FRCC Operating Committee (OC), pursuant to a specific exemption request from the respective GO. An exemption shall be based on the following condition[risk Factor: High], [ Time Horizon: Long-term Planning]:. R3.1. If an equal or greater amount of load is shed note 1, simultaneously with the generator trip. note 1: The load shed shall: 1) not be part of an FRCC Automatic Underfrequency Load Shedding (UFLS) program, step, load block, and 2) be located within the same FRCC Regional UFLS load shedding zone. R4. GOs claiming an exemption under R3, shall provide documentation of exemption approval by the FRCC OC and documentation demonstrating adherence to the conditions set forth in Deleted: ensure that Deleted: result in Deleted: upon Deleted: Deleted:.

2 C. Measures: requirement R3.1, to the FRCC within 30 days of a specific FRCC documentation request. M1. GO shall maintain documentation that each generator meets the requirements defined in R1 of this standard. M2. GO shall have evidence that the FRCC was provided with documentation demonstrating adherence to the requirements defined in R1, within 30 calendar days of a specific FRCC documentation. M3. GO shall, have evidence that the FRCC was provided with documentation demonstrating adherence to the requirements defined in R3, within 30 calendar days of a specific FRCC documentation. M4. A GO claiming an exemption under R3 shall, have evidence that the exemption has been approved by the FRCC OC and that the exemption complies with the load shedding requirements of R3.1. D. Compliance: None 1. Compliance Monitoring Process 1.1 Compliance Monitoring Responsibility: FRCC Regional Entity 1.2 Compliance Monitoring Period and Reset Timeframe: One calendar year 1.3 Data Retention: The GO shall retain documentation required in M1 and M4 of this standard, for a minimum of three (3) years. 1.4 Additional Compliance Information: 2. Violation Severity Levels (VSLs) 2.1. Lower: There shall be a Lower VSL non-compliance if any of the following Deleted:, Deleted: request, provide the FRCC with documentation that it meets the requirements defined in R1. Deleted: within 30 calendar days of a request, provide the FRCC with documentation that it meets the requirements defined in R3, as appropriate. Deleted: within 30 calendar days of a request, provide documentation Deleted: The Compliance Monitor shall retain any audit data for three years. Deleted: GOs shall demonstrate compliance through self certification or audit (periodic, as part of targeted monitoring or initiated by complaint or event), as determined by the Compliance Monitor. Deleted: 2. Levels of Non- Compliance 2.1 Level 1 Documentation of compliance is not provided to the FRCC in a timely manner (within thirty days of request) or is not available for inspection. <#>Level 2 Documentation of an FRCC OC, approved, exemption request as allowed in R3 of this standard is not provided to the FRCC in a timely manner (within thirty days of request) or is not available for inspection. Deleted: <#>Level 3 A GO does not comply with the load shed amounts as stipulated in an approved exemption (as allowed in R3), and as defined in R3.1. <#>Level 4 Protection and control settings applicable to this standard do not comply with FRCC Regional Generator Coordination Requirements as specified in Appendix A of this Standard.

3 2.1.1 GO with generators applicable under this standard did not provide appropriate documentation within 30 days of a specific FRCC documentation request (reference Measures M2. and M3.of this standard) Moderate: There shall be a Moderate VSL non-compliance if any of the following GO with generators, applicable under this standard do not provide appropriate documentation within 60 days of a specific FRCC documentation request (reference Measures M2. and M3. of this standard) High: There shall be a High VSL non-compliance if any of the following conditions is present: A GO with a generator applicable under this standard (or multiple generators) did not provide appropriate documentation within 60 days of a specific FRCC documentation request (reference Measures M2. and M3.of this standard) A GO with a generator applicable under this standard, has generator protection settings for an individual generator (or multiple generators) that do not meet the frequency bands and timing set-points stipulated in A GO with a generator applicable under this standard, has generator protection settings for an individual generator (or multiple generators) that meet less than 100% of required nominal voltage settings and corresponding timing set-points stipulated in A GO with a generator applicable under this standard, has generator volts/hertz protection settings for an individual generator (or multiple generators) that do not meet the settings requirements stipulated in A GO with a generator applicable under this standard, has generator protection settings that includes generator phase overcurrent relays or backup phase distance relays applied to an individual generator (or multiple generators), that do not meet the setting requirements stipulated in A GO with a generator applicable under this standard, claiming an exemption for an individual generator (or multiple generators) under requirement R3 of this standard, does not have an exemption approved by the FRCC OC.
