It is an eyesore, and I wish power wasn't necessary but hopefully the wounds will heal eventually.. There have been times in the past where they have built big hydro schemes which have healed to an extent. Take the Fannaichs for instance - Its great fun walking the big pipe back to the road instead of the track, and while there are a few signs of hydro about, it is a long way from horrific.
It would be nice if we had sufficient space for hydro schemes to generate enough power for the country and have enough space left to fit all our wilderness areas into as well, but I guess we are too small a country for both to fit in comfortably, and a comprimise has to be reached.
I personally think that hydro schemes are slightly better than the wind farms - more useful for longer and the visual impact is far less in the long run.
I do have big reservations about the developers doing what they say to put the damage right though, and we need far better inspections to make sure obligations are stuck to.
I was recently round the back of S Glenshiel ridge. I came across a new hydro scheme, (made an uncrossable river crossable - hurrah) followed the track that had inevitably been built for installation for a couple of KM, where it disappeared just out of sight from civilisation. I was very sceptical that the whole track wasn't supposed to be removed and get put right, but obviously the inspector isn't going to get his boots dirty, so just the end of the track was enough
