Step one was to get rid of the power lines and any dust, using content aware fill and the healing brush respectively.
Then I used a blank layer set to Soft Light and painted at a very low opacity(5%-11%) with white to bring back detail in the shadows.
I opened up the foreground more using a Curves layer set to Screen that's masking out the background. This is an interesting technique, you don't actually change the curves layer, just the blending mode and then adjust the opacity. I also darkened the sky a bit and lightened the whole scene just a little.
Probably the most important thing I did with this image was brightening up the blades at the end, it really makes them pop from the background and the entire image, without the contrast there this image really doesn't work.
Lastly, using a Black and White adjustment layer I used the blues in the image to brighten everything up and really bring out the three planes in this image.
