Overview

IntroductionThe SPP Balancing Authority (BA) is required by NERC to evaluate all Interchange Tags to ensure adequate Ramp Capability is available prior to approval. SPP Operations Engineering determines the Ramp Capability within SPP Balancing Authority Area (BAA) through analysis of available Resources in the Integrated Marketplace. SPP has developed a Ramp Reservation System (RRS) to allow Transmission Customer’s (TCs) to view the Ramp that is available within the SPP BAA at any given time and to reserve the Ramp needed for their transactions prior to tagging the transaction. All submissions of tagged Interchange Transactions into or out of the SPP BA will be evaluated against available Ramp Capability prior to approval by SPP. Ramp availability may be verified and pre-arranged by TCs (as mapped to Asset Owners (AOs)) ahead of submission of an e-Tag through the RRS. Subsequent submission of a Tag in which scheduled interchange is supported by an approved Ramp Reservation will be automatically approved with respect to Ramp Capability. Use of the RRS is voluntary, but if an AO does not reserve Ramp prior to entering an e-Tag, a Ramp Reservation will be automatically created for the Customer if there is available Ramp. Tagged transactions submitted without a Ramp Reservation or those that exceed the Ramp reserved by the AO will be checked for remaining Ramp Capability and approved if available. Otherwise, the e-Tag will be limited to the reserved Ramp or will be denied if Ramp was not reserved and there is no available Ramp. Ramp validation is only applicable to scheduled interchange that impacts SPP NSI (i.e. imports or exports of Energy to/from the SPP BA). Ramp validation is not performed on tagged transactions wheeling through the SPP BA.

RampCapabilitySPP Operations will determine the available Ramp Capability within the SPP BAA based on current operating conditions and generation availability within the Integrated Marketplace. Ramp Capability is the maximum sustainable Ramp-Up and Ramp-Down capability expressed in MWs per minute.

RampReservationBusinessRulesEvery e-Tag that is submitted by the CPSE where the Generating Control Area (GCA) or Load Control Area (LCA) is specified as “SWPP” will be validated for available Ramp Capability. Tags wheeling through the SPP BA where neither GCA nor LCA are “SWPP” will not be validated for Ramp.



The Energy MW profile at the first (import) or last (export) Tag physical path segment listing “SWPP” as the Scheduling Entity (SE) will be used to validate Ramp Capability. If no explicit start/stop Ramp duration information is supplied in the e-Tag, the Eastern Interconnection default Ramp duration of 10 minutes will be used for this validation. In the event that the start/stop Ramp durations specified in the e-Tag overlap such that there is insufficient time to reach the block accounting scheduled Energy MWs specified, the e-Tag will be denied by SPP (e.g. a schedule profile segment with start/stop duration of 15 minutes specified with a 20 minute start/stop ramp duration).

RampReservationValidationThe Integrated Marketplace Ramp Validation will first determine the Ramp-Up or Ramp-Down Capability required, in MWs/minute, at each schedule breakpoint based on the change in the proposed scheduled interchange Energy MWs divided by the Ramp duration. The Ramp Validation will then determine if there are any unscheduled Ramp commitments held by the CPSE under one or more Ramp Reservations matching the Ramp start/stop times specified in the e-Tag at each schedule breakpoint. If so, the unscheduled Ramp commitments held on those Ramp Reservations will be allocated first to support the proposed e-Tag schedule. Any additional Ramp Capability required beyond that supported by one or more Ramp Reservations, or the entire Ramp Capability required by the proposed scheduled interchange in the case where the CPSE does not have any supporting Ramp Reservation(s), will be validated against the remaining Ramp-Up or Ramp-Down Capability available. If there is sufficient Ramp Capability available to support the e-Tag transaction, Ramp commitments will be allocated to support the proposed scheduled interchange and the e-Tag will be approved, subject to passing all other e-Tag validations, by SPP. That is, an implied Ramp Reservation will be committed to support the e-Tag from the remaining SPP Ramp Capability for the Ramp required in excess of any pre-arranged Ramp Reservation(s) held by the CPSE on a first-come-first-served basis. If the proposed e-Tag schedule would violate SPP Ramp Capability at any point in time, the e-Tag will be denied by SPP. The Ramp Validation will respect the netting of simultaneous Ramp Up and Ramp Down commitments according to SPP rules for such netting.

RampReservationDeadlines

Reserved Ramp that has not been tagged will be released for the entire Operating Day (OD) immediately after the Day-Ahead (DA) Market closing time.

Real-Time (RT) Reserved Ramp that has not been tagged will be released for the entire duration of the Ramp Reservation at 30 minutes prior to the Reserved Ramp start time.



Tags submitted by the TC subsequent to the release of any Reserved Ramp will be validated against the remaining available Ramp Capability in the order submitted.

If a TC/Market Participant (MP) does not submit a specific Ramp Reservation Request, the system will evaluate the submitted e-Tag against the available capability. If sufficient capability is available, the system will automatically generate a Ramp Reservation when the schedule is submitted.

RampReservationSystem(RRS)

The RRS is part of the OATI RTOSS Scheduling Service. MPs or authorized AOs may gain secured login access to the SPP RTOSS Scheduling Service and the RRS with an authorized Username and Password in addition to an OATI x.509 electronic certificate issued by the OATI webCARES system. The RTOSS Scheduling Service is available over the Internet. Market Participants are directed to the OATI Help Desk at (763)-201-2010 to obtain an authorized user account on the SPP RTOSS system. Please see the SMT 33.0 RRS Scenario Document for the URL to be used for SMT.

Step Action Comments

1 Open WebTrans via the Internet.

2 Click on the Click Here to Enter link/ User Login Screen displays.

3 Enter your credentials in the User Name and Password fields.

4 Click Login. WebTrans dashboard displays with a toolbar at the top.

5 Click Marketplace from the homepage toolbar.

A drop-down menu displays.

6 Select Ramp from the menu, then Ramp Reservation Summary from the sub-menu.

A screen displays with approved ramp reservations and button that allows you to enter a new reservation.



RampReservation(Submission)DisplayThe TC/MP or authorized AOs may submit Ramp Reservation Requests using the RRS. Ramp Reservations are limited to a single designated OD in the SPP Integrated Marketplace. Ramp Reservations may be submitted and approved up to seven (7) days prior to a given OD in accordance with the SPP Integrated Marketplace Bid/Offer submission window. Ramp Reservation requests will be approved immediately upon submission subject to the verification of available Ramp-Up or Ramp-Down Capability; after accounting for all other approved Ramp Reservations and approved or pending e-Tags. The available Ramp Capability in either direction will be offset by simultaneous reserved or tagged Ramp commitments made in the opposite direction in accordance with netting rules established by the SPP Integrated Marketplace. The Ramp Reservation Entry Form is accessible from the Ramp Reservation Summary display, which allows entry of a Ramp Reservation Request.


1 Click Ramp Reservation Entry. The Ramp Reservation Entry screen displays with a blank entry form.

2 Enter the necessary data in the fields, including: • Provider (e.g. SWPP) • Operating Day • Customer (e.g. Your PSE Code) • Direction (Direction of Flow; e.g. Import) • Start Time and Stop Time (Always CP) • Energy MW (MW Amount to be reserved)

The information on the right side of the screen populates after you click Check, as shown in the next step.



After entering the Ramp Reservation data, the Customer has several options shown at the bottom of the screen.

Option Action Comments

1 Click Check. This option will check the available Ramp-Up and Ramp-Down Capability needed to support the proposed scheduled interchange profile.

Any violations of the total SPP Ramp Capability in either direction will be indicated and allow for the user to adjust the Energy profile as needed to avoid the Ramp violations.

No Ramp commitments are held with the ‘Check’ option, and there is no guarantee that subsequent submission of the Ramp reservation request will be approved.

2 Click Commit. This option will perform the available Ramp-Up and Ramp-Down Capability verification; and if there is no violation of total SPP Ramp Capability in either direction, the Ramp Reservation will be approved and a corresponding Ramp commitment for the proposed scheduled interchange will be held for the MP.

If any violations of the total SPP Ramp Capability in either direction are detected, those violations will be indicated and allow for the user to adjust the Energy profile as needed to avoid the Ramp violations similar to the ‘Check’ option.

3 Click Clear. This option clears the data entered and allows the user to start with a clean screen.

4 Click Close. This option closes the screen. If this option is checked prior to clicking Commit, the data will be lost.



RampReservationStatusRamp Reservations that have been approved may be viewed from the Ramp Reservation Summary display. Details of the Ramp Reservation proposed scheduled interchange profile, and all pending or approved e-Tags that have been submitted that are supported by a given Ramp Reservation may be viewed by clicking on the assigned Ramp Reservation ID from the Ramp Reservation Data display. The ID displays in blue on the left of the screen below.

After clicking on the Reservation ID for the PSE bucket, the Ramp Reservation Detail display will provide the details for that particular reservation. If a Tag has been created against the Ramp reserved, the Tag will be indicated in the Ramp Commitment section.



RampAvailabilitySPP’s Ramp availability is the amount of up/down Ramp left and ready to be reserved. It will change based on reservations and Tags submitted, and it will be deducted from the Ramp Capability of 600.
