Subsequently, the NPCC Task Force on Coordination of Operation (TFCO) initiated a comprehensive comparison of NPCC Directory#9 Verification of Generator Gross and Net Real Power Capability and Directory#10 Verification of Generator Gross and Net Reactive Capability with the requirements of MOD-25-2 in order to assess the reliability impact of retiring all or part of the criteria contained within Directories #9 and #10. The TFCO has determined that most of the more stringent or more specific criteria found within Directories #9 and #10 are also addressed in the requirements of MOD-25-2 or another currently enforceable NERC standard. Additionally, the TFCO concluded that the existing NPCC verification program which requires the TOP to administer real and reactive power testing procedures among the GOs in its local area will no longer be required since MOD-25-2 assigns applicability for real and reactive power testing directly to the GO. Accordingly, the TFCO has recommended that the regional criteria in NPCC Directories #9 and #10 containing the verification requirements for real and reactive power should be retired effective July 1st, 2019 to coincide with the completion of the MOD-25-2 Implementation Plan. The TFCO review revealed portions of the Directory#9 criteria (Real Power Verification) that were either more stringent or more specific than the requirements in MOD-025-2 and are not addressed in either MOD-25-2 or another NERC standard: Frequency of Real Power Testing---Directory#9 Criteria Requirement R8 obligates a real power capability test every 3 years while MOD-25-2 Requirement R1.1 (Attachment 1) requires real power capability verification every 5 years. Sustainability of Real Power Verification Testing---Directory#9 Criteria Requirements R16, R17, R18 and R19 address the sustainability of real power testing for specific types of generation (thermal, gas turbines, hydro and combined cycle) and requires such testing to demonstrate sustainability for no less than one hour. MOD-25-2 does not address sustainability for verification testing by specific generation type; but rather requires maximum real power testing for one hour on the general basis of synchronized generation. TFCO has concluded that retiring these more stringent or more specific criteria attributes does not create a significant reliability gap. Do you agree with the TFCO conclusion? Yes  FORMCHECKBOX  No  FORMCHECKBOX  Comments:  FORMTEXT       The TFCO review also revealed portions of the Directory#10 (Reactive Power Verification) that were either more stringent or more specific than the requirements in MOD-025-2 and are not addressed in either MOD-25-2 or another NERC standard: Sustainability of Reactive Power Verification Testing---Directory#10 Criteria Requirement R18 sets forth sustainability requirements for leading and lagging reactive power testing. R18 stipulates leading reactive power output for 15 consecutive minutes and lagging reactive power output for at least 60 consecutive minutes. Although MOD-25-2 does require sustainability for lagging VAR tests of one hour there is no sustainability requirement for a leading VAR test. Correct Limitations to Real Power Capability---Directory#10 Criteria Requirement R5 requires the GO to document a time frame for correcting equipment limitations impacting reactive power capability and MOD-25-2 does not have a similar requirement. Although TOP-002-2.1b Requirement R15 does obligate the GO to provide the TOP with a 7 day forecast of real power output there is no comparable notification for reactive power capability and therefore the criteria in Directory#10 is more stringent. TFCO has concluded that retiring these more stringent or more specific criteria attributes does not create a significant reliability gap. Do you agree with the TFCO conclusion? Yes  FORMCHECKBOX  No  FORMCHECKBOX  Comments:  FORMTEXT       Directories #9 and #10 currently require testing on a periodic seasonal basis. (Directory#9 Criteria Requirement R8 and Directory #10 Criteria Requirement R8) and seasonal testing requirements are absent in MOD-025-2. However, TOP-002-2.1b Requirement R13 currently obligates a GO to perform testing at any time at the request of the TOP/BA. (This requirement has been mapped to TOP-003-3 Requirement R5 which is subject to future enforcement). TFCO has concluded that the seasonal testing criteria in Directories #9 and #10 although more specific than the testing requirements in MOD-025-2 does not create a significant reliability gap and the seasonal testing criteria can be retired.
