California ISO 2019 Q1 Full Network Model Implementation and Master File Data Freeze

SUMMARY

The California ISO 2019 Q1 Full Network Model implementation is scheduled for effective trade date Feb. 21, 2019. Processing of requests for Master File data changes, except the changes related to registered cost updates, will be frozen for effective trade dates February 14-21 as a part of the implementation of this new model. The submission of Use-Limited Plan Data Template (ULPDT) will not be impacted by the data freeze.


MESSAGE

The ISO Full Network Model version 2019 Q1 implementation is scheduled for effective date Thursday, Feb. 21, 2019.

 

The 2019 Q1 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 February 19 to 21, 2019. The submission of Use-Limited Plan Data Template (ULPDT) will not be impacted by the data freeze.
