The reason you can't find the number that makes them appear is because they are not enabled in the default map configuration (which I believe is named default_map_settings.cfg, although I'm not 100% sure.) Anyways, you'll need to make a custom cfg specifically for your map that includes the power lines if you want to use them. They should be commented out somewhere in the aforementioned default map configuration.
