California ISO Tariff Section 20 Notice of Requests for Information

SUMMARY

The California Energy Commission (CEC) has issued and served a subpoena on the California ISO directing the ISO to provide data to the CEC for a variety of analytical tasks. This information will also be used for participation in California Public Utilities Commission (CPUC) activities on resource adequacy program design and planning reserve margin-related proceedings. The due date for any objections to the production of responsive information is noon (Pacific Time) on Friday, May 31, 2019.


MESSAGE

The CEC has issued and served a subpoena on the ISO directing the ISO to provide certain data to the CEC for a variety of analytical tasks, which include:

  • Preparation of the biennial Integrated Energy Policy Report
  • Assessment of the replacement infrastructure needed to accommodate the retirement of aging facilities, including those that utilize once-through cooling
  • Statewide and local electricity supply adequacy, including annual assessment of expected reliability during summer peak demand periods

This information also will be used to participate in CPUC activities pertaining to Resource Adequacy program design and implementation, and planning reserve margin-related proceedings.

 

The ISO will seek confidential treatment of such documents and information to the extent the requested documents and information are confidential or commercially sensitive under the ISO Tariff Section 20. A copy of the subpoena and letter outlining the ISO's and CEC's mutual understanding about confidentiality of the data requested are available at http://www.caiso.com/Documents/CEC_2019_RA_Subpoena.pdf and http://www.caiso.com/Documents/CEC_Confidentiality_Letter_2019_Subpoena.pdf. This subpoena reflects collaborative revisions to the previous CEC subpoena issued in 2018.

 

Any market participant that objects to the ISO producing the requested documents and information must submit their objection by noon (Pacific Time) on Friday, May 31, 2019, along with a court order or other appropriate order that prohibits disclosure in response to the subpoena. Unless the ISO receives such an order by the listed due date, the ISO will thereafter respond to the subpoena.

 


CONTACT INFORMATION

Please direct any such order, as well as any questions or comments, to ISO Senior Counsel John Spomer at jspomer@caiso.com and to ISO Paralegal Martha Sedgley at msedgley@caiso.com.
