Incidents of disclosure of information
Posted on 2/18/11 at request of Integrys/Wisconsin Public Service:
On February 18, 2011 at approximately 3:30pm Central Time, there was an improper disclosure of non-public transmission function information by a transmission function employee to a marketing function employee. At a joint meeting that included the transmission function employee and the marketing function employee, the transmission function employee inadvertently disclosed the outage of a 138 kV transmission line located in the Western UPPCO service territory and indicated that the line was expected to return to service in about 1 hour. The transmission function employee’s disclosure was based on information received from American Transmission Company, LLC (ATC). After the disclosure occurred, the joint meeting was immediately concluded and Integrys investigated the disclosure. Integrys contacted ATC concerning the improper disclosure and completed this posting required by the Commission’s regulations.

Potential merger partners

The following appeared in the third quarter Form 10-Q filed by Allete, Inc. with the U.S. Securities and Exchange Commission:

“ATC is a for-profit transmission-only company created by the transfer of transmission assets previously owned by several electric utilities serving the upper Midwest. In April 2003, the PSCW approved a transfer of interests in the Wausau-to-Duluth electric transmission line project to ATC. As a result, ATC has assumed primary responsibility for the overall management of the project and will own and operate the completed Wausau-to-Duluth line. We have a contractual opportunity related to ATC that, if exercised, would ultimately result in our having an equity investment in ATC. We intend, if approved by other parties, to invest $60 million in ATC by the end of 2006.”

Based on preliminary analysis, ATC Board approval of Allete's membership is required.
