Dinorwig Power Station 1980'S

These photos were taken soon after Dinorwig opened. I had two tours, one beforehand when I was unable to taken any photos, and this one when I was. As they show some areas not open to the public and a lot of thw weork was done by Blaenau people, I thought they might be of interest.
