The California ISO will open the Cluster 14 Application Window for Generation Interconnection Request Applications from April 1, 2021 to April 15, 2021. Interconnection customers may only submit application requests during this window to be included in Cluster 14. Applications will only be accepted electronically using the CAISO’s Resource Information Management System (RIMS). More details of the Interconnection Request application (Page 1-56) and electronic submittal (page 57) process are available at http://www.caiso.com/Documents/Presentation1-InterconnectionApplicationOptionsandProcess.pdf.
In addition, it is of critical importance that interconnection customers review the tariff provisions for the minimum Interconnection Request tariff requirements described in Tariff Section 3.5.1 Initiating an Interconnection Request and Tariff Section 3.5.2 Validation of Interconnection Request. Interconnection Requests that are incomplete when the window closes with not be included in Cluster 14.
Customers submitting interconnection requests for proposed energy storage facilities who desire firm charging service to reduce the risk of curtailments during charging must contact their interconnecting participating transmission owner (PTO) to request separate firm load interconnection studies. The ISO will request additional operational information/characteristics prior to scoping meetings for these types of projects. Storage project customers will submit the same interconnection request identified above. Please include any applicable additional information related to the project with the Interconnection Request submittal.
