FERC Approves ISO Enhancements to Generator Interconnection Request Submission and Validation Process

SUMMARY

The California ISO has received approval from the Federal Energy Regulatory Commission (FERC) for a filing of tariff revisions to enhance and clarify the process for submitting generator interconnection requests.


MESSAGE

On April 1, 2019, the Federal Energy Regulatory Commission (FERC) approved the ISO's Feb. 7, 2019 filing of tariff revisions to the Generator Interconnection and Deliverability Allocation Procedures in Appendix DD of the ISO Tariff. The revisions enhance the generator interconnection process by: (i) clarifying what constitutes a "complete" interconnection request and what constitutes a "valid" interconnection request; (ii) extending the validation period, for curing deficiencies in submitted data, from May 31 to June 30; (iii) removing the requirement that interconnection requests must be valid before the ISO can schedule scoping meetings; and (iv) providing interconnection customers with day-for-day extensions to deadlines when the ISO cannot meet its response deadlines for documentation submitted before May 31. The changes proposed in the tariff revisions were part of the ISO's 2018 Interconnection Process Enhancements stakeholder initiative.

 

The FERC order is available on FERC's website at http://elibrary.ferc.gov:0/idmws/File_list.asp?document_id=14757064.

 

The ISO FERC filing with the FERC approved tariff language is available at http://www.caiso.com/Documents/DraftFinalClusterWindowTariffRevisions-InterconnectionProcessEnhancements2018.docx.

 

The Cluster 12 Application Window for Generation Interconnection Request Applications is now open, and closes April 15, 2019. It is of critical importance that interconnection customers review the following new tariff revisions approved by FERC:

  • New minimum IR tariff requirements described in Tariff Section 3.5.1 Initiating an Interconnection Request
  • Revisions to the IR validation processes described in Tariff Section 3.5.2 Validation of Interconnection Request

The Interconnection Request application forms and samples have been posted to the ISO website at http://www.caiso.com/planning/Pages/GeneratorInterconnection/InterconnectionRequest/Default.aspx.


CONTACT INFORMATION

Interconnection customers with questions on the revisions to the generator interconnection request submission and validation process and the Cluster 12 interconnection request application window may contact the ISO interconnection Resources team at IRinfo@caiso.com or 916-936-6854.
