Projects that are required to submit an affidavit:

The Generator Interconnection and Deliverability Allocation Procedures (GIDAP) BPM contains the affidavit scoring methodology for determining the order for allocating TP Deliverability to eligible projects in each allocation group.
The ISO will accept an e-mail copy of documentation for retention or notarized affidavits for seeking an allocation. The notarization must be in jurat form. All documents are due by Feb. 14, 2024.
