Assembly Concurrent Resolution 188: Update on posting of draft summary report

In response to the requests set forth in Assembly Concurrent Resolution (ACR) 188, the California ISO is working with the National Renewable Energy Laboratory (NREL) and other California Balancing Authorities to produce a draft report summarizing recent relevant studies on the impacts of expanded regional cooperation on California and, among other things, discuss engagement between neighboring states on regional transmission organizations in the west.


The drafting team needs additional time to generate the draft report.  While the ISO initially planned to post the draft before the end of 2022, it will now look to post by mid-January 2023. The ISO will host a stakeholder call to discuss the draft report in January 2023, accept stakeholder comments on the draft report, and submit a final report to the Legislature by the end of February 2023.


Additional information is available on the Regional Solutions webpage. Further updates on the ACR 188 schedule will be provided in early January.


Please contact Tim Kamermayer at or ISO Customer Service at 916-608-7320 with any questions.
