"all those "saved" watthours will get sucked up by their subscribers' homes. Then what, shut down the datacenter until things get warm again?"
Why assume the saved watt-hours just disappear? If local residential demand absorbs them, Google can still buy power from elsewhere. The interesting economic question is why Google finds it cheaper to pay consumers to curtail usage than to acquire additional supply through the grid. That suggests congestion, transmission limits, [price gouging, psychological noise,] or peak pricing are the real bottlenecks, not total electricity production.
