08/11/2011 : (Notice - Replaces previous 07/10/11 and 04/16/11 posting) Daily Non-Firm (DNF) Evaluation: Effective August 11, 2011 the MAPP MTA system implemented a software update concerning ATC/AFC decrementing when Non-Firm Daily TSRs are evaluated in the Operating Horizon. Due to the FERC Order No. 729 implementation, the Operating Horizon was increased from 36 hours to 48 hours. Under the old definition, Non-Firm Daily TSRs were validated completely outside the Operating Horizon. Once the Operating Horizon was expanded to 48 hours, Non-Firm Daily TSRs could now fall within the Operating Horizon, yet their impacts were not included in the AFC/ATC calculation. This software change allowed the validation to treat daily non-firm impacts as hourly non-firm impacts in the AFCcalc engine to correctly decrement ATC/AFC in the Operating Horizon. Announcement of this software update was also posted on the MAPP OASIS site on the MAPP Home page. OATI has indicated that with the software update the posting and evaluation Daily Non-Firm against the posted ATC/AFC in the Operating Horizon is consistent with other WebTrans systems.

05/27/2010: Announcement that WAUE.AECI.CM Service Point has been Disabled

Western has disabled the WAUE.AECI.CM Service Point on its OASIS effective 5/27/2010. Western also requested that TranServ (acting on behalf of MAPP) disable the same Service Point on the MAPP Schedule F OASIS page, and received notification that it was also disabled on that page effective 5/27/2010.

Transmission Customers can continue to utilize the WAUE.AECI Service Point on UGPR's WAPA OASIS page when requesting transmission service from UGPR, which is the same interface point between WAUE and AECI at the Maryville 161-kV substation.

The WAUE.AECI.CM point was setup to allow for reservations across Western's Creston-Maryville 161-kV transmission line (WAUE-AECI-CM contract path) under the MAPP Schedule F tariff or UGPR's OATT. However, requests utilizing the WAUE.AECI.CM Service Point are not being properly evaluated across the entire Sioux City - Denison - Exira - Creston - Maryville contract path (WAUE-AECI contract path) when the source Service Point on the reservation is located upstream of the WAUE-AECI contract path. Therefore, until such time as that can be resolved in the MAPP OASIS backend, the WAUE.AECI.CM Service Point will be disabled. If, in the interim, a Transmission Customer needs to submit a transmission service request for only the path from Creston-Maryville (WAUE-AECI-CM contract path) using the available source Service Points of WAUE.ALTW or WAUE.MEC at Creston, such requests will be handled on a manual basis by contacting Western or TranServ (as Western's TSC).

If you have any questions, please contact Steve Sanders (Western) at 406-255-2840, or by email at sanders@wapa.gov.

Questions concerning short-term transmission service requests can be directed to TranServ (as Western's TSC) as noted in the following posting: WAPA-Customer-Notification-TranServ-as-TSC.pdf

08/25/2009 : MAPP Schedule F service no longer available effective 9/1/2009; TranServ beginning operations as Western's Transmission Service Contractor (TSC) effective 0000 CDT on 9/1/2009 to assist in the processing of Transmission Service Requests on the WAPA OASIS; Corn Belt Power Cooperative changes effective 9/1/2009.

Western has obtained the services of TranServ International, Inc. (TranServ) to perform as its Transmission Service Coordinator (TSC) starting effective September 1, 2009 at 0000 (CDT). Based upon the departure of MidAmerican Energy Company from MAPP on September 1, 2009, the regional MAPP Schedule F tariff will no longer be available to customers to take transmission service across Western's Integrated System. Therefore, effective September 1, 2009 all service on Western's transmission system will need to be obtained under Western's Open Access Transmission Tariff (OATT) and requested on Western's OASIS (WAPA TP OASIS). TranServ will assist Western in the processing of the majority of short-term transmission service requests (TSRs). Western personnel will continue to process Monthly Firm and Long-Term TSRs. The delineation of responsibilities for processing TSRs starting September 1, 2009 is outlined in the following document:

To assist Western's customer with the transition associated with the end of MAPP Schedule F and the introduction of TranServ as TSC in processing TSRs Western and TranServ will host conference calls starting on August 31, 2009 at 1500 (CDT) to answer customer questions and explain the changes being implemented. In addition, Western will answer questions regarding the changes associated with the move of Corn Belt Power Cooperative (CBPC) into Western's WAUE Balancing Authority Area and inclusion of a portion of CBPC transmission facilities into the Integrated System. More information regarding the CBPC changes is noted in the updated 07/22/2009 news item below. The announcement of the conference calls is outlined in the following letter:

07/22/2009 (Updated 06/10/2010) : Corn Belt Power Cooperative (CBPC) move into Western's east-side "WAUE" Balancing Authority Area (Control Area) and addition of CBPC transmission facilities to Integrated System (IS) effective September 1, 2009

CBPC Facilities - GI/TSR Submission Reqmts

08/25/2009 Update: Western will be including eligible portions of the Corn Belt Power Cooperativce (CBPC) transmission facilities located in western Iowa in the Western/Basin Electric Power Cooperative/Heartland Consumers Power District Integrated System (IS), and the change will be effective on September 1, 2009. The following CBPC transmission facilities will be included in the IS as Basin Electric Power Cooperative leased facilities:

Wisdom to Osgood 161 kV transmission line � 30.64 miles
Osgood to Burt 161 kV transmission line � 29.79 miles
Burt to Hancock 161 kV transmission line � 33.70 miles
Wisdom to Buena Vista 161 kV transmission line � 32.77 miles
Buena Vista to Sac County 161 kV transmission line � 9.66 miles
Hope to Webster 161 kV transmission line � 12.39 miles
Burt to Hope 161 kV transmission line � 34.61 miles

Hope substation (161 kV portion only)
Wisdom substation (161 kV portion only)
Burt substation (161 kV portion only)
Osgood substation (161 kV portion only)
Webster substation (161 kV portion only)
Hancock substation (161 kV portion only)

Interconnection and transmission service requests utilizing these facilities will need to be submitted to Western, as the IS administrator, pursuant to Western's OATT and LGIP/SGIP, starting on September 1, 2009 at 0000 (CDT). Western and CBPC will work with existing interconnection and transmission service customers on the CBPC facilities listed above to address any transition issues. The IS transmission rates will apply to service across the facilities above, and preliminary analysis shows no expected increase to the IS rate as the result of inclusion of the CBPC facilities and associated new network load into the IS. CBPC will continue to adminster its own tariff on the remaining CBPC facilities that are moving into Western's WAUE Balancing Authority Area on September 1, 2009, and therefore interconnection and transmission service requests on those other CBPC facilities will continue to be submitted to CBPC.

===========================

07/22/2009 Posting: Corn Belt Power Cooperativce (CBPC) intends to move its transmission system located presently in the MidAmerican Energy Company (MEC) Balancing Authority Area/Control Area (BAA) into Western's east-side "WAUE" BAA by September 1, 2009, as a result of MEC's plan to join the Midwest ISO on September 1, 2009 and move its facilities into the Midwest ISO BAA. CBPC and the Integrated System are also exploring the possibility of eligible portions of the CBPC transmission facilities becoming part of the Integrated System (IS) as a result of this BAA change, and that change would also occur on September 1, 2009. Western will post additional details in near future regarding the potential inclusion of CBPC transmission facilities into the IS, and the impacts upon such a change on interconnection and transmission service requests located on those CBPC transmission facilities, and preliminary information regarding potential IS rate impacts. This information will be located on Western's OASIS page under "Recent News" and also under a documents folder named "CBPC BAA Move Information", if necessary. More information concerning CBPC and its members is available on their company web page at: http://www.cbpower.coop/aspx/CBPower/default.aspx
