Businesses work with Power companies to vary electrical load/generation
 

I've heard lots of talk about how this can be done, but this is the first I think I've seen of it actually being done. Its great to see that it is finally being implimented. Basically they have the power company communicating automatically with other businesses to throttle their machines up or down depending on the available power in the grid. This evens out power usage and makes things run more efficiently.
