Reason For Revision

•       As part of FERC Order 841 "A Scheduling Coordinator (SC) representing an NGR resource associated with a UDC or Retail Utility that is unable or unwilling to separate wholesale and retail charges may request the CAISO to assign a special classification that will exempt the NGR from CAISO charges for negative energy. Such request by the SC must meet criteria and documentation requirements as specified by the CAISO in the Metering BPM."

•       To comply with the FERC Order, CAISO needs to zero out the settlement of this special classication where there is negative energy, which required modifying the Charge Codes listed in the BPM Section of this document.

  • The Real Time Energy Quantity 5.21 will consume the new primary indicator of these resources and, with additional logic to determine wholesale settlement eligibility based on negative energy, pass this on to the other affected charge codes.
  • The other indicated Charge Codes will now zero out the settlement of negative energy for these resources when negative energy exists.
  • RTM Net Amount 5.35 also includes changes related to MSS Net Hourly PDRs Ineligible for BCR.

 

The effective date of the changes is 10/1/2020 and the anticipated implementation date is 9/29/2020.
