Reminder from PJM:  PJM 2020 Summer Capacity Verification Tests are due by September 20

Actions Requested by PJM:

  • Share this communication internally within your organization to anyone who may need this information.
  • The PJM 2020 Summer Capacity Verification Test period ended at September 1, 2020 at 0000 hours. PJM 2020 Summer Capacity Verification Test data and any associated derates for failed tests must be submitted by September 20, 2020.

The 2020 Summer Verification Test period ran from June 1, 2020 through August 31, 2020. All units in the PJM Capacity Market should have tested to prove their Summer Installed Capacity during this time. Additionally, all units, with the exception of Hydro, Pumped Storage Hydro, Fuel Cell and Diesel (or other reciprocating engines), must correct their test data for the local generator site ambient conditions under which their test is performed to the rated conditions under which their ICAP is determined.

Review the posted PJM Capacity Verification Testing FAQs as there is a new Capacity Verification Test format and screen that require (in some cases) you to submit more pertinent test information.

Units that are affected by ambient conditions must also have their test performed within certain ambient condition limits:  

  • For any unit with once through cooling or multi-pass cooling, tests must be performed when the actual (observed) intake water temperature is within 5° F of the rated intake water temperature.
  • For any unit with wet cooling (including those with evaporative cooling, fogging, wet compression and chillers), tests must be performed when the actual (observed) wet bulb temperature is within 10° F of the rated wet bulb temperature.
  • For any unit with dry cooling (or no cooling as in combustion turbines without inlet cooling), tests must be performed when the actual (observed) dry bulb temperature is within 20° F of the rated dry bulb temperature.
  • Alternatively, if it is impractical to test within the aforementioned limits, testing can occur without adherence to the limits as long as from July 7 through August 31 the testing 
    • start time is 10:00 a.m. EPT or later and
    • end time is 10:00 p.m. EPT or earlier on any day. 

Manual 21 contains information pertaining to testing within required ambient condition bounds and all other testing requirements.
