It's not just a case of creating power... Or not as the case may be. Where you see a 'big-ish' isolated wind turbine, you'll often see at its base is a box with a satellite dish on it... Often these turbines are private and power farms etc, but do backfeed to the grid. - What the dish is doing is providing a two-way link to network control. The reason they do that is that it's cheaper than running a phone line to the thing! - Which might not even be physically possible.
Remember, the masts need a connection to the network themselves, sometimes that can be achieved by a cable or point-to-point microwave, sometimes it cant!
Before satellite there were great swathes of Scotland where television reception was impossible or very difficult! - Did you know for instance that one of the first cable-tv systems (possibly THE first) in the UK was set up in and around Saltcoats by local electrical dealer Harris's? A mast set up just below Knockrivoch farm 'relayed' signals to the town below, which was blocked from reception of signals from the Darvel or Blackhill transmitters by the steeply-sloping hills. - The Harris Relay only really started to fall out of favour when satellite dishes became smaller and more popular, and I suspect by now it's been subsumed by Virgin or the like... But our terrain does present issues, and not always just in the obscure corners of the nation.
