DUK's divy is looks great but beware of a trend, FE's divy was just cut in half from just over 7%.
D's divy is about 3.6 but their growth has made up the difference.
Also be aware of fuel for generation. About a year ago ? DUK was denied a permit for a new NUK in Fla. NUKs are going by the wayside in favor of gas generation. However it's possible they could split @ about $75.
AEP has a good divy and appears to be a solid utility for having some coal generation. But again, many utilities are moving towards gas gereration.
I've netted about 100K (on paper) from D for 2013. Their Nat. Gas play & MLP with Blue Racer, and the likelyhood they may purchase an existing pipeline utility adding to their infrastructure, moving them closer to Canadain pipelines eventually to inter-connect.
D has 2 LNG conversion plants , and exports out of Cove Point Md. has been approved for the MLP.
