9 9 Task 1: Submit OASIS TSR Step 3: Evaluation Evaluation of Reservation Request –Tariff Administration evaluates Transmission Service Requests using the following criteria: Verify adequate capacity on the fifteen most limiting constrained facilities on the flow path in the OASIS request If negative AFC exists on one of the fifteen most constrained flowgates then the request could receive a counter-offer or be denied –Status is assigned to Transmission Reservation

10 10 Task 1: Submit OASIS TSR Step 3: Evaluation States of a Service Request –Queued- Indicates initial status on receipt of a customer purchase request or TSR –Study - Indicates some level of study is required to evaluate a request –Accepted (by Midwest ISO) - Indicates the service request has been approved /accepted –Confirmed (by PSE) - Indicates the request has been confirmed and a transmission service request exists –Withdrawn - Indicates the customer has withdrawn the request from further action during the evaluation process –Counter-Offer - Indicates partial acceptance of a request due to limited AFC, FTR availability –Refused – indicates the Midwest ISO has refused the request Note : Only the most common states are listed here. Refer to the Open Access Tariff Business Practices for the complete list.
