Where I come from, the hydroelectric plants are run partly according to the price. There are rules, the rivers can't be dry, but as far as permitted, the operators let the water flow when the price is high. Much of the weather forecasting is paid for by that; the power generating companies model electricity demand for the coming hours and days.

Where I live right now, the farmers are building things like this: https://upload.wikimedia.org/wikipedia/commons/thumb/f/fa/20... The green things are more or less balloons, because it pays to store the gas until peak time and burn most of it then.

yeah, the only problem is how to apply this model to, say, south of US - California, Arizona, New Mexico, Nevada etc. Not a lot of hydro around

not sure how it is applicable to electric storage
