From this ring line several 60 kV lines branch, which are all implemented as underground cables.

This high-elevation segment of 500 kV line is also said to be problematic.

The other 345 kV lines going out of the plant go south towards Milwaukee.

Several 138 kV lines going out of the plant supply electricity to the surrounding area.

By 1997, the huge increase in irrigation loads were putting a strain on the 33 and 11 kV lines.

This makes rapid isolation of a fault on the 138 kV line very slow.

A 345 kV line carrying the same load across the same distance has losses of 4.2%.

The new interconnection has been online since 2009 and the 315 kV line is fully operational since 2010.

Some high voltage circuits are often erected on the same tower as 110 kV lines.

There are two double-circuit 345 kV lines, portions of it become single circuit.
