6.7.1 Completed Projects

Some inadequacies in the Southeast Zone that were identified in earlier Biennial Reports were alleviated through the construction and completion of specific projects over the last two years. Information about each of the completed projects is summarized briefly in the table below, and those matters will be removed from the list of inadequacies that are discussed in the 2009 Report. More detailed information about these projects and inadequacies can be found in the 2005 and 2007 Reports and in the PUC Docket for the matter if the project fell within the jurisdiction of the Public Utilities Commission, in which case the Docket Number is shown below. Also, additional information is available by contacting the designated person for the utility that was responsible for constructing the project.

Tracking Number Utility Description PUC Docket Date Completed
2005-SE-N1 Xcel Energy Mankato Generation Capacity increases on three 115 kV lines CN-03-1884 2009
2005-SE-N2 Xcel Energy Cannon Falls Generation Three New 115 kV lines (3.6 miles total length) and one new substation TL-06-459 2009
