Two basic approaches exist for automating gas scheduling and nominations to interstate pipeline electronic bulletin boards, or EBB’s: 1. A flat-file upload which typically requires a scheduler to login to the EBB and then upload a file. Or 2. EDI adapters that are designed to fully automate the scheduling process with a two-way EBB communication featuring no manual intervention. Note: For no manual intervention, a company’s energy trading & risk management, or ETRM system must be integrated with the scheduling EDI adapter; this can be a tough task for older technologies.
