I have seen them knock out electrical transformers on power poles to houses, there use to be a reset button's on them. We had this problem a lot at my grandfathers place. They got started on my grandfathers house up at his ranch. Pecked holes all in the siding of his house. After my grandfather died a couple years ago, my uncle went and put Hardie panel siding, a concrete type siding on the house so the woodpeckers couldn't peck holes all in it. Well it took them about 3 months to peck holes in it. My uncle called me a told and told me about all the damage they were doing to the ranch, I told him they were a Northern Wood Pecker, migrating down here in the winter. They can peck though any thing. You guys know how it is, the further you get away from home the harder the pecker gets.
