I have updated the GIC Modeling Expectations document and will present the updates tomorrow. There are three updates:

1.       Added descriptions for branch RLNSHI and RLNSHJ fields which are in the provided template but did not exist in the GIC Modeling Expectations

2.       Added how to model underground cables

3.       Changed the substation RG value to be 99 and not 99999 when the station is ungrounded

4.       The PSSE Version has been changed to version 34.5.1 per the request of ERCOT Planning.


If you have any comments on the changes please raise them at the meeting tomorrow. All changes have been tracked.
