10.4.8 Request for extension of submission deadlines for Electromagnetic Transient Models
The following process applies to participating generators that are required to submit Electromagnetic Transient Models (EMT) to the CAISO and the applicable PTO. Participating generators may request an extension of the submission deadlines for their EMT models if they are facing significant challenges in procuring them from outside vendors or Original Equipment Manufacturers (OEM), specifically due to the vintage of their equipment. It is the CAISO’s understanding that the EMT model requires significant levels of proprietary information from the OEM. The expertise to develop such EMT models is not widely available, and when there are competing needs for the expertise, the priority is typically given to the newer equipment, which causes significant delays in development of EMT models for older generating units. In light of this information, the CAISO has proposed the following process for participating generators to request extensions for submission of EMT models. The CAISO will update the “Resource Category and Phase All Participating Resource IDs” spreadsheet to include a list of generating units that are subject to EMT model requirements, which will allow increased lead time for participating generators to develop new EMT models . In light of this, the CAISO is making this process applicable only to participating generators subject to Phase 1, 2, 3, and 4, submission deadline requirements.
Extension request process:
Steps for generating units:
- Email should be sent at least 30 CD prior to the applicable submission deadline that an extension is being requested for.
- Subject line of email request should read “BPM Model Submission <Resource ID> <Generating unit name>”, sent to GridModelingData@caiso.com and the applicable PTO mailbox identified in Section 10.4.1.
- Send email request to the CAISO and applicable PTO with the following details:
o Name and resource ID of generators the extension is being requested for.
o Brief description of the reason for request, including documentation from the OEM regarding the timeline for development of models and cost, if appropriate.
o Proposed deadline for submission of the EMT Model.
- The CAISO and PTO shall review the request and provide approval/rejection within 15 CD of receipt of request. The extension, if granted, will apply only to EMT model submissions, with all other data and models required to be submitted by the initial submission deadline.
