Capacity Network Resource Capability (CNRC) Outcomes

IN THIS SECTION

The capacity network resource capability (CNRC) value applies to all generating and import capacity resources except import capacity resources associated with an external elective transmission upgrade (ETU). Such import capacity resources should see Capacity Network Import Capability (CNIC) Outcomes.

The CNRC defines the following:

The capacity network resource interconnection service rights that must be maintained for a resource
Whether an interconnection request is required for a proposed increase in capacity network resource capability in accordance with Schedule 22, Standard Large Generator Interconnection Procedures and Schedule 23, Standard Small Generator Interconnection Procedures of the Open Access Transmission Tariff (OATT)
Whether an initial interconnection analysis is required under FCM qualification for a proposed increase in output from an existing generating capacity resource

CNRC Value and Determinants

The CNRC is generally determined by the capacity supply obligation (CSO) obtained in a Forward Capacity Auction (FCA) or through a subsequent reconfiguration auction or CSO bilateral period. Because new resources and new incremental portions of existing resources have not yet obtained a CSO, in lieu of a CNRC for these resources, the ISO uses a temporary value called the potential capacity network resource capability (PCNRC—details below). This temporary PCNRC converts to a CNRC, as described below, once a CSO is obtained.

New Resources

FCA: A new resource that obtains a CSO receives a CNRC of equal value. This CNRC is effective from the capacity commitment period (CCP) start date.
Reconfiguration auction: A new resource that has a potential capacity network resource capability and obtains a CSO through an annual reconfiguration auction receives a CNRC of equal value. This CNRC is effective from the corresponding CCP start date.

Existing Resources with New Incremental Portion

FCA: An existing resource that obtains a CSO for a new increment receives a CNRC of equal value plus the existing CNRC. This CNRC is effective from the capacity commitment period start date.
Reconfiguration auction: An existing resource that uses a potential capacity network resource capability to obtain a CSO for a new increment receives a CNRC equal to the annual reconfiguration auction CSO plus its existing CNRC. This new CNRC would be effective from the reconfiguration auction's corresponding CCP start date.

All Existing Resources

Retirement delist bids, or permanent delist bids: An existing resource that submits a retirement or permanent delist bid would have its existing CNRC value reduced, effective from the start date of the corresponding CCP. Learn more about retirement or permanent delist bids for existing generators, demand capacity resources, or imports.
Termination: An existing resource terminated from the market or subject to a three-year-nonoperational retirement would have its existing CNRC value reduced to reflect the termination or retirement effective immediately.

Potential Capacity Network Resource Capability

In lieu of a CNRC, a temporary PCNRC is used for the qualification of new resources in reconfiguration auctions and bilateral periods for a prior commitment period. For those reconfiguration auctions, new resources that clear the FCA—and those that don’t clear, but choose to elect critical path schedule (CPS) monitoring—are awarded a summer/winter PCNRC equal to their summer/winter CNRC under the following conditions:

The new project is FCM commercial or seeking to achieve all its CPS milestones by the start date of the relevant commitment period of the reconfiguration auction.
The addition of the new project does not have any adverse impact on the transmission system effective on that start date.

Accessing the CNRC or PCNRC

You can view the CNRC or PCNRC for your resource in the Forward Capacity Tracking System (FCTS); under the Basic Info tab.
