Hi, from the looks of the newest imagery (MAXAR at the moment, though I understand NAIP is upgrading to 2020 shortly), I'm willing to bet that the last few visible turbines have been demolished. I work on wind repowers and the tower knockdowns in the SW row look "in progress". I've gone ahead and added the lifecycle prefix demolished: to the power tag. If someone wants to capture and move to OHM then it is available. Otherwise, if the plant gets repowered, then the points can move to the new location and be updated.
