This is hard to verify because CAISO doesn’t clearly specify what is under construction and I don’t know how accurate date_proposed_online is. I filtered our gridstatus data on is_actionable and date_proposed_online < 2025 and got 19 GW.
GS data includes projects up to 3/2/2023, whereas the LBNL data includes data up to 7/7/2022. The differences could be explained by changes in the queue between 7/22 and 3/23. To do a fair comparison, we could wait until CAISO and LBNL interconnection queue data is updated.
In the meantime, some action items could be:
Reach out to Synapse or CAISO to better understand the difference between CAISO's two interconnection reports.
Reach out to LBNL to see when they plan to release new data
