ISO Interconnection agreement and queue management
After a resource has completed the study phases of the interconnection process the interconnection customer must sign contracts, install metering and telemetry equipment and ISO must model the resource in market systems before participation in the wholesale power market is allowed. This also applies to Demand Response resources that have completed the process of registering and requesting a customer resource ID.
