OASIS Subcommittee - Notification Task Force UPDATE

May 29 2013

2

Scope and Goal

Scope: NAESB has minimum standards to notify impacted parties of reductions or other changes as a result of Short-Term Competition and Preemption in WEQ-001 (“OASIS”) and WEQ-004 (“Coordinate Interchange”). Identify notification proposals for OASIS subcommittee (OS) discussion/motions.

Goal: Provide the OS with notification options for their consideration. Include (1) existing NAESB and other standards, (2) pro/cons of existing and proposed features, and (3) proposed recommendation.

Proposed Timeline – June 2013

Status

Current review Considered STF preemption scenarios

(requests and reservations) Developed draft e-Tag notification options (and

pros/cons) Reviewed current OASIS notification standards

Still to do Develop draft OASIS notification options (and

pros/cons) Review current e-Tag notification standards Consider STF competition scenarios Other?

E-Tag Notifications

1. Preemption (reductions) of a confirmed Reservation referenced on confirmed e-Tag(s)

2. Competition that results in a reduction of a confirmed Reservation that is referenced on confirmed e-Tag(s)

Did not look at e-Tag notification for Transmission Service Request that have been Superseded, as such transmission would not be part of confirmed e-Tag

6

E-Tags that have lost transmission capacity due to preemption or competition

This is a concern when confirmed reservations’ Conditional Window overlap into the Scheduling Window (primarily for Daily and Hourly products)

No procedure to appropriately allocate these type of reductions of transmission to confirmed e-Tags

When a reduced transmission reservation is referenced on multiple confirmed e-Tags, there could be many options on how that reduction is allocated to e-Tags

Currently, the authorized parties that may reduce the transmission profile of a confirmed e-Tag does not include the TCH. A tag author is the only party allowed to make a market adjustment to the Transmission Profile on a e-tag

Related E-Tag Standards

WEQ-004, Coordinate Interchange Addresses interchange deliveries Appendix A (“Transaction e-Tag

Actions”) describes “a reduction of transmission profile” as a possible e-Tag action of certain approval entities, requiring TP approval.

NERC reliability standards To be determined

88

E-Tags that have lost transmission capacity due to preemption or competition – Options being considered

Maintain Status Quo: Currently there is no requirement for a Transmission Provider or Transmission Customer to notify PSE/Tag Author via the e-tag process when the supporting Reservation has lost capacity

1. Auto-notification to all potentially impacted e-Tag parties of a potential issue.1. The TP send a Pre-Notification to PSE /Tag author when the TCH has lost Capacity

used to support the e-tag (Heads up notification)

2. Auto-notification to smaller group of potentially impacted e-Tag parties of more certain issue1. Allow the TCH to notify the Tag Author/PSE that they have lost their

Capacity on XXXXX A-ref via the e-tag process.3. Limit RFI (tagging) to the unconditional window

a) Shorten Conditional window for reservations b) Do not allow RFI to be Accepted if the supporting Reservation is still deemed in its

Unconditional window 4. Create ability for Transmission Contract Holder (TCH) to modify

certain e-Tags: Allow TCH to submit a downward adjustment to the e-tag energy and transmission profile when TCH has lost Capacity on the Aref used to support the e-tag

5. Create pro-rata methodology for TP to implement allocated transmission and energy profile reductions on e-tags (if no action)

OASIS notifications

Preempted OASIS requests (TSR that are Superseded)

Preempted OASIS reservations (NT has Pre-empted PTP)

Competed OASIS reservations (on hold until competition procedure is finalized)

The following are initial OASIS standard review for notification descriptions.

1010

Preempted OASIS requests

When PTP requests are not confirmed due to a subsequent, higher tiered request

001-4.17: once request is denied (and will be in its entirety), AREF of competing request and reason is to be described in the comment field

001-4.18: state change dynamically notified if customer requested such notification on OASIS

Others?

11

Preempted OASIS reservations

When confirmed, conditional PTP reservations are displaced or reduced by a higher tiered request

Same as for Preempted Requests, except that partial reductions are allowed.

013-2.4.1 (“Displacement-No ROFR”): the status of Displaced indicates reservation is displaced in its entirety. Otherwise, a portion is reduced.

Others?

1212

Competed OASIS reservations

When confirmed, conditional PTP reservations are not matched, or otherwise displaced/reduced by a higher tiered request

• 001-4.19: implies Counteroffer status made to notify “customer” the subsequent match offer

• 013-2.4.4 (“Displacement-With ROFR”): the following are the actions that will initiate electronic notification, if customer has elected to receive such notification

• Competing_Request_Flag is set to “Y”• Seller_Comments include the AREF of the competing request• The status change associated with the Customer’s matching request,

and the status change associated with that• Competing_Request_Flag is set back to “N” once the result of the

competition is resolved
