Rejected Requests

During an Aggregate Facilities Study, when SPP determines that a request cannot be granted because it does not meet the pre-defined study parameters set by the customer, SPP will notify the customer by setting the request’s status on OASIS to REFUSED. The purpose of this action is to allow the customer as much time as possible to prepare another request, if needed.

At the conclusion of the study, SPP will post additional information to allow the customer to determine which study parameters could not be met. SPP will not be obligated to provide this additional information prior to the conclusion of the study.

Open Season

Open Seasons for submission of requests in the Aggregate Transmission Service Study process shall be as follows:

Study ID / Open Season
AG1 / December 1 – May 31
AG2 / June 1 – November 30

Waivers for Base Plan Funding

Types of Waiver Requests

·  Type 1: Service request does not meet the requirements for Base Plan funding in Section III.B.1 of Attachment J; therefore a waiver of the requirements is requested. Requirements as currently stated in the Tariff are:

o  The Transmission Customer’s commitment to the Designated Resource has a duration of at least five years

o  In the first year the Designated Resource is planned to be used by the Transmission Customer, the accredited capacity of the Transmission Customer’s existing Designated Resources plus the lesser of: (a) the planned maximum net dependable capacity applicable to the Transmission Customer or (b) the requested capacity; shall not exceed 125% of the Transmission Customer’s projected system peak responsibility determined pursuant to SPP Criteria 2.

o  If the Designated Resource is a wind generation plant, then the sum of: (1) the requested capacity and (2) the transmission capacity reserved for the Transmission Customer’s existing Designated Resources that are wind generation plants shall not exceed 20% of the Transmission Customer’s projected system peak responsibility as determined pursuant to SPP Criteria 2 in the first year the Designated Resource is planned to be used by the Transmission Customer.

·  Type 2: Service request meets the requirements for Base Plan funding, but the allocated costs exceed the Safe Harbor Cost Limit applicable to the request; therefore a waiver of the allocated costs is requested.

Process for each type of Waiver

Type 1

Customers who anticipate that a request will not qualify for Base Plan funding under Attachment J should submit the Transmission Service Request (TSR) and waiver request sufficiently in advance such that the Board can act on the request prior to the close of the open season window. This is so the customer knows whether or not the waiver will be granted and the amount of Safe Harbor available and can either withdraw or commit to the study process accordingly.

Type 2

After the AFS-1 preview, if the allocated costs exceed the Directly Assigned Upgrade Cost (DAUC) parameter, the customer may leave the parameter unchanged. This will effectively cause the TSR to be removed from the study. Then, no more than 120 days prior to the next Board meeting, the customer submits a waiver request and an identical TSR in the open season. The request is processed in the next Board meeting, prior to the start of the next study. If the customer receives a waiver from the Board, the customer leaves the new TSR in the queue for the next study. The waiver of costs is applied in the next study. If the Board does not grant a sufficient waiver, the customer has the freedom to withdraw the request prior to the close of the open season window or proceed to enter the study.
