Electricity bill is on average $100 per household per month. People won't shift their usage because electricity is too cheap anyway. 1.6% of your revenue === 1.6% of your saving effort.
Note that the periodicity of wind blowing is days and weeks, so it's too long and too intermittent to align daily routines on it. Forget about charging your car or hot water aligned on it, the only solution we have scaled to use this wind energy is reversible dams / potential energy, and of that we have no more unexploited geography to support wind turbines. Feb 2019 we produced in Germany 10,000GWh with wind versus 3,000GWh in July 2019. And between 2 consecutive weeks, it can be a factor of x10 of difference. http://energynumbers.info/capacity-factors-at-danish-offshor...
That's not necessary. The utility can make the current price available via an internet API. The water heater can be connected to the internet and can read that data. Heat the water to 130 or so when electricity is cheap, heat it only to 100 or so when it is expensive. From personal experience, the water remains hot enough for a comfortable shower 3 days after the power goes out. This is more than a workable system. The hot water itself becomes the "battery".
And that's only the hot water heater. You can do it with the HVAC system (the thermal mass of the house becomes the "battery"), and with charging your car.
Right there it's a huge chunk of one's electricity consumption, all without needing grid storage batteries.
Also, to make this work best, appliances need to be connected to the internet and the power companies need to have an internet ABI where the current power price can be extracted by those appliances.
At last, an actual use for internet connected appliances!
Look at it this way. With enough variation over the day, you create a market for storage. Let's say stored electricity costs twice as much as direct, but the price of direct varies by 3x over the course of the day. You've now created an arbitrage market for buying cheap electricity during the day, and selling it at night.
Of course, the more storage gets built, the more the load (and thus cost) increases during the high-availability times, and the lower the selling price during demand spikes. And thus the market attains equilibrium.
The law of supply and demand is a marvelous thing sometimes.
Nope, I talked about incentivizing consumers to shift their demand based on a volatile price. I pointed out that much of this can be accomplished without need of batteries.
For example, have the hot water tank heat up water higher than normal when electricity is cheaper, and lower when electricity is more expensive. Hot water tanks lose heat very slowly, this could result in never needing to heat water during the expensive times.
It's a heluva lot cheaper than having a battery do it.
Second, it's not a single location. Wind may be lower in one location, but strong in another location 50 miles away. The idea that wind goes completely dead all at once across statewide areas is not how wind actually works.
The idea that wind currents are uncorrelated across geographical areas, even on the scale of states, is not how wind actually works.
Yes, the demand for HVAC is very high when the winds are low.
