1 | On January 28, 2003, certain information relating to the amount of energy then flowing on certain transmission lines operated by ATC was disclosed by an employee of Alliant Energy Company, an affiliate of ATC, during the course of a public hearing in a proceeding before the Wisconsin Public Service Commission in Docket No. 9343-CE-100. That information was provided to the Alliant Energy Company e next meassage... | MISO_TA | 02/13/2003 14:34:57 ES | 02/13/2003 14:34:57 ES | ATC
2 | To ATC's knowledge, no further dissemination of the information was made, and no use was made of the information. For further information concerning this matter, please contact Dan L. Sanford, Attorney, ATC Management Inc., corporate manager for ATC at: [email-masked], or (262) 506-6957. | MISO_TA | 02/13/2003 14:35:24 ES | 02/13/2003 14:35:24 ES | ATC
41 | American Transmission Company LLC has declared an emergency due to high water levels in the Dead River in the Upper Peninsula of Michigan and the potential for related disruption to transmission service. This will permit timely direct communications, if necessary, between ATCLLC, the Midwest Independent System Operator and load serving utilities in the Upper Peninsula of Michigan. | MISO_TA | 05/15/2003 10:49:11 ES | 05/15/2003 10:49:11 ES | KB
61 | On July 15, 2004, a consultant for the American Transmission Company LLC (ATC), shared some preliminary results of a Loss of Load Expectation (LOLE) analysis being performed by ATC, with one of ATC's transmission customers. Even though the consultant had been instructed not to share any results except with representatives of ATC, he provided certain information relating to the availability of and the preliminary impact of that availability on the LOLE. | itadmin | 07/26/2004 13:32:55 ES | 07/29/2004 15:27:54 ES | ATC
62 | Because the results are preliminary and are not related to available import capability, but rather to how much import capability would be necessary to meet the LOLE reliability criterion, it is unclear whether or not the information shared would provide any competitive advantage. Not withstanding the preliminary nature of the information, ATC is posting this information and has provided further instruction on the need to limit the dissemination of preliminary, unpublished study results. | itadmin | 07/26/2004 13:33:16 ES | 07/29/2004 15:28:35 ES | ATC
101 | On August 4, 2004, ATC and one of its interconnected parties were engaged in preliminary discussions of outage scheduling for the purpose of transmission outage and planning coordination when, apparently, some of the content of those discussions was communicated to market function employees. That content included a proposal for outage of Line 16343 for work to replace that line and/or some of its related terminal equipment at National and Empire substations during an undetermined time that might include October 2004 or Spring 2005. ATC has conducted a review of this situation and has had discussions with representatives of the interconnected party regarding the limitations to be imposed on the communication of such information. | hzhang | 08/10/2004 14:27:49 ES | 08/12/2004 16:04:17 ES | ATC

201 | On January 27, 2005, ATC, responding to a request from an affiliate, sent two ATC Operating Guides to an affiliate employee who is not among those designated on a Confidential Data Access Agreement as eligible to receive non-public transmission-sensitive information. The ATC employee mistakenly believed that the documents were available on a public website at MISO when, in fact, access to that MISO website is restricted. For a copy of those documents, "Emergency Flowgate 11637" and "V-308 RRN-WES 345kV", please contact Peter Burke at 262-506-6863 or [email-masked]. | itadmin | 01/28/2005 15:51:45 ES | 09/13/2005 13:24:48 ES | ATC
221 | On August 24, 2005, ATC requested an outage on a line on its system that through the Outage Scheduler of the Midwest Independent Transmission System Operator be posted on OASIS. As of August 26, 2005 at 8:30 a.m. the outage has not been posted. ATC discussed the requested outage with a marketing representative of the Energy or Marketing Affiliate whose transmission service would be affected by the requested outage. | itadmin | 08/26/2005 10:31:33 ES | 08/29/2005 12:06:39 ES | ATC
262 | ATC has suspended their Standards of Conduct associated with the Wausau, WI area transmission system as a result of a forced outage to the Weston-Rocky Run 345 kV line. This forced outage, in conjunction with other outages in the area, result in the need for effective load curtailment to maintain system reliability. This suspension is effective 11:03 1/16/2006 c.s.t. | itadmin | 01/16/2006 13:05:29 ES | 01/16/2006 13:05:29 ES | ATC
263 | Effective 16:30 1/16/2006 EST: MISO & ATC have reinstated their Standards of Conduct associated with the Wausau,WI area transmission system as a result of a forced outage to the Weston-Rocky Run 345 kV line. | itadmin | 01/16/2006 16:39:57 ES | 01/16/2006 16:39:57 ES | ATC
282 | MISO suspends the Code of Conduct in the WPS control area. This is for problems associated with the Weston bus. | MISO_TA | 03/11/2006 01:42:27 ES | 03/11/2006 01:42:27 ES | MISO
286 | AS of 0500 EST, MISO reinstates the Code of Conduct for the WPS control area. | MISO_TA | 03/12/2006 05:07:58 ES | 03/12/2006 05:07:58 ES | MISO
