The creation of residual mix Certificates is discussed in section 12.2 of the NYGATS Operating Procedures.
The NYGATS Settlement will convert all Certificates remaining in the Active Subaccounts of all Account Holders into Unsettled Certificates. When Settlement is run all Unsettled Certificates from the previous vintage year will be converted to Residual Mix according to the rules described in Table 12.1 (see below). The NYGATS Administrator will create Residual Mix Certificates based on the Unsettled Certificates which will include Certificates in the Administrator’s Account associated with Unregistered Generators.
The Attributes contained on any Unsettled Certificate shall become part of the pool of Attributes upon which the Residual Mix Certificates shall be based.
Unsettled Certificates applied to the Residual Mix will be automatically retired and cease to exist for the purposes of the NYGATS. All Banked Certificates for the generation year that was Settled will not be included in the Residual Mix and will be available for transfer between Account Holders, export, or for transfer into the Retirement Subaccount.
