Reason For Revision
​Submitted by Susan R. Schneider​, Phoenix Consulting 

​​​Clarify that projects receiving permission to operate before all upgrades are complete, pursuant to a Limited Operation Study, can provide Resource Adequacy under specific circumstances even though all of their Assigned Network Upgrades are not yet complete.

Effective date: Effective at end of PRR process.

CAISO rules usually require that all Precursor and Assigned Network Upgrades be complete before a project with a TPD Allocation receives its applicable FCDS or PCDS designation.  However, projects can interconnect and operate before completion of all their reliability-related upgrades pursuant to a Limited Operation Study. 

​This PRR is needed to clarify that such projects can receive FCDS or PCDS, as applicable, once their deliverability-related upgrades are in service, even if reliability-related upgrades are not yet complete.  If the project can operate without the incomplete upgrades, they should be able to provide full RA services.​

Announcements
This PRR is on hold to give the CAISO an opportunity to develop language that better accomplishes LSA’s purpose.
