Blackouts occur when it's hot for a few reason. Wires heat up and catch fire thus breaking and causing a break in service. Transformers heat up and the fluid inside them can sometimes boil and the transformer will actually explode which will take out blocks and blocks and blocks. Also look at like this. It's 6pm everyone just got home from a days work and they all turn there AC
's on all at the same time. The power grids can't take it, substations go on overload trying to supply enough power and sometimes fail causing a huge problem and fire. I'll try an find the fire from Yonkers NY.
Couldn't find the one from Yonkers but here's one we used in training so you get the idea. We have 4 in my district and believe me were watching them closely.
