The heatwave in the Northeast (or Summer as we call it here in Florida), it's putting a stain on Power companies.
Brown outs have occurred as people are doing what they can to stay cool. The power companies having been urging customers to try and conserve power as the system is being taxed to the max.
CBS is done their part during the heatwave to not strain the system. The CBS Broadcast Center in NYC has been operating on generator power, pulling itself off the grid, to help ease the power demand on Con Edison.
