_________________________________________________________________________________________________________________
ATC is currently available on Avista System's BPATPUD path (an Avista path to/from MIDCRemote in lieu of using the MIDC path). If you are scheduling with BPAT at MIDCRemote, no additional scheduling charges will apply with the purchase of transmission on Avista's System's BPATPUD paths (such as AVAT.NWMT > BPATPUD or BPATPUD > AVAT.NWMT). Scheduling may also be arranged to MIDC via BPATPUD with other MIDC participants. Please see the BPATPUD Reservations and Scheduling documents in the Customer News Folder for additional information!
Effective June 1, 2009, Avista, Bonneville, Idaho Power, NorthWestern and PacifiCorp have agreed to implement new capacity management procedures associated with the use of the Hot Springs POR/POD, the Amps Line, and the Montana-to-Northwest Path. Materials regarding these capacity management procedures have been posted and may be found in the Customer News folder – Hot Springs Scheduling Changes – June 2009 folder. Within this folder you will find “Scheduling News/Tagging Examples,” the Amps “Capacity Management Agreement,” and the “Hot Springs – FAQ” document. Avista’s historical HSTP POR/POD and BURKE POR/POD have been combined into a single POR/POD named AVAT.NWMT. A new diagram identifying Avista’s Posted Paths may be found under the Provider Information folder titled “AVA OASIS Stick Diagram – June 2009.” The effective date for schedules using the new POR/POD of AVAT.NWMT is June 2. Pre-schedule will be handled as follows: On Monday, June 1, pre-scheduling will take place for June 2. The new POR/POD’s (AVAT.NWMT, BPAT.NWMT) will be used. Pre-schedule for June 1 will be this Friday, May 29, and will use the existing POR/POD’s. Real Time will be handled as follows: Effective hour beginning 00:00, hour ending 01:00 PDT on June 2, real time TSR’s and Tags will use the new Paths and POR/POD’s. Real Time for May 30, May 31, and June 1 will use existing POR/POD’s. For additional information, please contact Warren Clark at 509-495-4186, Cathy Williams or John Underwood at 509-495-4819.
Intra-Hour Scheduling Proposed Business Practice Avista has posted in the Business Practices/Proposed Business Practices folder a document titled Draft BP for Intra-Hour Scheduling (5-1-09) for 30 day comment. This Business Practice covers the Intra-Hour purchase of transmission service, and the associated process for scheduling that transmission. The Business Practice is being developed in coordination w/ the Joint Initiative, and through Avista's membership in ColumbiaGrid. If you have any questions or comments to provide on the draft Business Practices, please contact Kenny Dillon at (509) 495-4436 or kenny.dillon@avistacorp.com. Transmission Rate Review Avista is currently in the process of reviewing its FERC jurisdictional transmission rates under its Open Access Transmission Tariff and currently plans to submit a request to FERC to change such rates prior to the end of 2009. In preparation for this filing, Avista may seek input from active transmission customers and FERC. If you have any questions, please contact Jeff Schlect, Manager, Transmission Services at (509) 495-4851 or transmission.services@avistacorp.com.
INTERIM Tagging Protocol for Transactions through Hot Springs between NWMT and BPAT Please Note: There is not an “Interim” tagging protocol when AVAT is a transmission provider for schedules using Hot Springs as a POR/POD. A change to these tag templates will not be necessary. Effective April 1, 2009 and continuing through May 31, 2009, Avista, Bonneville, Idaho Power, NorthWestern and PacifiCorp are implementing an INTERIM tagging protocol for transactions scheduled through the Hot Springs POR/POD. Please see The “Customer News” folder to the left, and reference the “Hot Springs Interim Tagging Protocol” item for tagging examples for this interim tagging approach. This tagging protocol is being employed on a temporary basis to facilitate compliance with applicable reliability standards prior to implementation of a more comprehensive series of capacity management procedures. Therefore, tag authors need to adjust their templates using the structure identified in the above referenced tagging examples. Such tags will need to be submitted on a Preschedule basis on March 31, 2009 for flow on April 1, 2009. Effective June 1, 2009, Avista, Bonneville, Idaho Power, NorthWestern and PacifiCorp have agreed to implement new capacity management procedures associated with the use of the Hot Springs POR/POD, the Amps Line, and the Montana-to-Northwest Path. Materials regarding these capacity management procedures and associated tagging protocols, including tagging examples, are being developed and will be provided for review prior to implementation.
Effective March 16, 2009, Avista has posted a clarification regarding tagging practices associated with the BPATPUD POR/POD. Additional information is posted as “BPATPUD Reservations and Scheduling” under the Customer News folder to the left of this page. Avista is able to accept tags via the BPATPUD POR/POD to and from CHPD, GCPD, and BPAT-MIDCRemote. In addition to this change, a simultaneous window will be established beginning March 16, 2009 and ending March 28, 2009 at 00:00, during which all requests for long-term transmission service to and from BPATPUD will be deemed to be submitted simultaneously. For further information, please contact Warren Clark at 509-495-4186 or Kenneth Dillon at 509-495-4436.
