I think I recall reading not too long ago about how in isolated cases recently, the price of electricity can go negative. This presumably would mean that people are being paid to waste it. But really, they're being paid to help keep the grid stable and running.

Most utilities don't have any way to store large amounts of energy, and it's non trivial to start up most energy generation. To me the grid looks like something between wizardry and a house of cards.
