It seems to me that another factor in the decline has been the decline in manufacturing in the USA. I know that when the Fukushima disaster struck, the net reduction in available power in Japan caused significant problems in manufacturing - hinting that manufacturing was a large consumer of the grid power. It was easier to see that effect when Fukishima was suddenly shut down, but in the USA the manufacturing has been slowly and consistently trickling to the far east for many years, gradually reducing the electrical demand.
