California ISO 2019 Q2 Full Network Model Implementation and Master File Data Freeze |
MESSAGE
The California ISO Full Network Model version 2019 Q2 implementation is scheduled for effective date Thursday, May 23, 2019.
The 2019 Q2 model version incorporates the addition or modification of new transmission, generation, and telemetry projects. The promotion process places limitations on the ability to process Master File data changes; therefore, the ISO will honor a data freeze as outlined below. Please note Master File data changes for registered cost updates will not be subject to this data freeze; however, these changes may not be effective from May 21 to 23, 2019. The submission of Use-Limited Plan Data Template (ULPDT) will not be impacted by the data freeze.
