The local power utility yard has  been busy replacing power poles in the last few years. When asked, a person on the crew said that sometimes they replace poles completely in a particular area. However most of the replacement comes from the results of  drilling and testing poles. The poles have plastic plugs put in them and numbers of them can be seen in some poles.

The telephone company also has lines on some hydro poles  lower then the power lines and they must coöperate in maintenance..

About twenty years ago  the utility drove galvanised steel beams by some  poles and bolted them to the beams.They are not apparently doing that now. And when asked about scheduling  the source said he was not aware of any schedule and that  it was ad hoc as far as replacement was concerned.
