Electricity price is already adapted hour per hour on the European Market. When the wind blows in Germany, price sometimes even go negative: it costs operationally less to energy producers to pay people to use the energy than stopping equipment. No change has been noted on the electricity usage.
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.

- WalterBright 7y ago> to align daily routines on it 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.
