After all, "under" is not the only way which is not "over", a longer above ground route on poles "around" might be much cheaper?
Unfortunately the only option here is to go underground. Due to the location of the powerlines and some natural features re-routing it will cause a large diversion which I doubt would be cheaper or even possible given the layout.
