Accurate network modeling supports efficient market operations
Modeling is based on detailed information for transmission network elements, resources and entities participating in the wholesale market.
Market participant asset implementation
This process provides a high level understanding of participating in the ISO Full Network Model process from a design and implementation standpoint that includes transmission and new resource implementation.
The network model defines system parameters, price node and market scheduling limit mappings and planned network model updates.

Master file schedule
Resource data submission
The Generator Resource Data Template and the Intertie Resource Data Template are used to submit requests to add or change specific operating parameters that reside in the Master File. For updates to existing data, scheduling coordinators must make any changes on the templates downloaded from the Master File user interface or application programming interface. Scheduling coordinators then submit updated templates using the user interface UPLOAD function or the programming interface SUBMIT services. Requests for new system resources should be sent to RDT@caiso.com in the New Intertie Resource Request template.
Major maintenance forms and instructions
Resources that have operational or environmental restrictions that limit production hours but can operate for a minimum set of consecutive trading hours may be considered use-limited. New registration requests, use plan submissions and any questions should be sent to RDT@caiso.com.
