Please note that all CRES Providers submitting for registration in AEP Ohio territory are required to participate in EDI Certification Flight Testing. This Testing is a collaborative effort involving multiple registering CRES Providers over a defined period. The CRES Provider and its contracted EDI Vendor or In-house EDI Service are expected to maintain necessary and timely communication with AEP and also between the CRES Provider and the EDI Vendor, and must agree to timely responses throughout testing. No response or late response to requested test transactions delay both the testing and ultimately the completed registration of all CRES Provider participants. If an EDI Vendor, In-House EDI Service or CRES Provider is found to be unresponsive or uncooperative during the testing, the CRES Provider (and its contracted EDI Vendor or In-house EDI Service) will be removed from the ongoing EDI Flight Test and the pending CRES Provider registration will be suspended. The non-performing CRES Provider will be evaluated for inclusion in a future EDI Flight Test.
