Task 1: Submit OASIS TSRStep 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

Task 1: Submit OASIS TSRStep 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confirmed and a transmission service request exists– Withdrawn - Indicates the customer has withdrawn the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.
