9/14/11 Update regarding Granville – Butler 138 kV line congestion mitigation: Additional work will be required to allow the proposed line ratings shared in the 5/26/11 posting below. The original completion estimates of the end of 2011 or early 2012 are still valid.
5/26/11: The following information is available regarding Granville – Butler 138 kV line congestion mitigation. ATC continues to observe increasing congestion on Granville-Butler 138 kV line in Southeast Wisconsin. To help reduce it, ATC is pursuing short-term upgrades involving terminal equipment at Butler and Tosa substations to allow Granville-Butler and Granville-Tosa 138 kV lines to operate at their full capability. The schedule and in-service dates are under development, and will be posted when available, but most likely these projects will be completed by the end of 2011 or early 2012.
Granville – Butler 138 kV line (3453)
Existing Ratings (MVA): 293 SN/339 SE/377 WN/406 WE
Proposed Ratings (MVA): 293 SN/403 SE/381 WN/461 WE
Granville-Tosa 138 kV line (3443)
Existing Ratings (MVA): 287 SN/287 SE/287 WN/287 WE
Proposed Ratings (MVA): 293 SN/403 SE/381 WN/461 WE

11/08/10: As a result of detailed engineering analysis, there has been a change to the Pleasant Prairie-Zion (#2221) 345 kV Line Congestion Relief Projects cost due to scope increase. However, there is no change to the economic benefits metrics posted on 10/14. The revised cost estimate and the summary of benefits are available by accessing the link below.

10/01/10: The following information is available regarding Pleasant Prairie-Zion (#2221) 345 kV Line Congestion Relief Projects. ATC currently is conducting necessary planning and engineering work on following projects to address congestion on the Pleasant Prairie-Zion 345-kV line which is a tie line between Illinois and Wisconsin: replace wave trap at Zion Substation, replace jumper at Zion Substation, and update ratings based on the LIDAR survey. Please note that Zion Substation in owned by ComEd in Illinois, and ATC has been coordinating this work with ComEd. These projects are tentatively planned to be completed by March 2011. In addition, ATC will continue to provide status and resulting ratings changes to MISO for the relevant models and studies. Please contact Jamal Khudai in ATC planning at jkhudai@atcllc or by phone at (262) 506-6166 if you have any questions.
7/20/10: ATC is continuing to finalize studies of the ATC Energy Collaborative – Michigan. ATC is hosting discussions of final design parameters Flow Control solutions in the east UP and mitigation options for contingency low voltage events in the central UP. ATC has already begun meeting with customers, including We Energies on July 20, 2010. To request discussion documents or to request a meeting with ATC on this matter, please contact Mike Burow in ATC Customer Relations at mburow@atcllc or by phone at (262)506-6793.

Update on the Presque Isle RATS implementation, 7/17/08
7/2/08: In response to a question from a marketing employee of an Energy Affiliate, ATC yesterday provided the following information:
The ReliabilityFirst Corporation (RFC) performed an assessment of incremental transfer capability between regions of the Eastern Interconnection for the summer of 2011. This assessment identified a potential constraint on the Pleasant Prairie to Zion 345-kV line ATC-ComEd tie line for ATC exports to Northern Illinois. The limiting component is noted as a wave trap on the transmission line, which might be resolved by an inexpensive project. ATC communicated that replacing the wave trap might increase the line rating from 973 MVA summer normal and 1069 MVA summer emergency rating to 1096 MVA summer normal/emergency rating.
For an intact system condition, the net change in the Pleasant Prairie to Zion 345-kV line rating with the removal of the wave trap limit would be 123 MVA (1096 MVA – 973 MVA). The increase in Normal Incremental Transfer Capability (NITC) would be +369 MW based on an ATC export to Northern Illinois transfer distribution factor of 33.3%. This would increase NITC to approximately 1,700 MW.
Under contingency conditions, the net change in the Pleasant Prairie to Zion 345-kV line rating with the remove of the wave trap limit would be 27 MVA (1096 MVA – 1069 MVA). The increase in First Contingency Incremental Transfer Capability (FCITC) would be +79 MW based on an ATC export to Northern Illinois transfer distribution factor of 34.0%. This would increase FCITC to approximately 1,400 MW.

In keeping with its outreach efforts on long-range planning, ATC will host an Economic Project Planning meeting for customers and stakeholders on Thursday, February 21 from 9:30am until Noon at MRA conference center near ATC’s Pewaukee office. The meeting will examine the historical performance of highly constrained elements of the electric system and their impacts on the delivered cost of electricity. This evaluation will help ATC identify a set of economic system needs and potential solutions. A map to the conference center and the meeting agenda are attached to this message. Please note that a teleconference option will be available for this meeting and lunch will be provided.
The precursor to this Economic Project Planning meeting was ATC’s Access Initiative. The original purpose of the Access Initiative was to examine an interstate transmission line connection between Wisconsin and the Midwest Region with customer and stakeholder input. ATC’s Access Initiative culminated in 2005 with a decision to pursue regulatory approvals for the Paddock-Rockdale project, now pending before the Public Service Commission of Wisconsin. The Initiative has now evolved to a broader analysis of future economic constraints and potential solutions.
Additional information about this meeting and the economic planning process including meeting notices, minutes, analyses and updates will be made available on ATC’s 10-Year Assessment website and on the OASIS.
Please indicate your participation in person or by phone by replying to Terry Peterson no later than end of day Friday, February 15.
ATC looks forward to seeing you at the meeting!
