6.7.11 Harmony-Beaver Creek 161 kV Line

Tracking Number. 2009-SE-N1

Utility. Dairyland Power Cooperative

Inadequacy. The Harmony-Beaver Creek 161 kV line is one section of a three terminal Harmony-Rice-Adams 161 kV line. MISO’s G551 – Point of Interconnection Change Report identified the Harmony-Beaver Creek 161 kV line section as an injection constraint for the 100 MW wind farm in Howard County, Iowa.

A map of the Harmony-Beaver Creek 161 kV line section is on the following page.

Alternatives. No alternatives to reconductoring the line are possible.

Analysis. The line rating of the Harmony-Beaver Creek 161 kV line section will need to be increased in order for G551 to generate at full output.

Schedule. Dairyland Power Cooperative will reconductor the line with 795 ACSS conductor and raise some of the 161 kV structures for an increased line rating. The estimated completion date is March 31, 2010.
