You paint too broad a brush.

There have been *serious* problems as new technologies have drawn from the grid 
and increased useage.

As plasma and other big screen TVs got big, various parts of my city had 
serious issues with power outages, as the system wasn't designed for those 
loads. And these weren't areas that had been there for 100 years. Relatively 
new housing developments had continuing power problems.  Our City Council had 
to really squeeze the utility to get capacity increased to handle the loads.
