Construction costs are currently skyrocketing

But first, you need facilities that allow local throttling. Here, the basic supplier offers a cheaper tariff that can switch off your wallbox if needed via a small additional box with a mobile network connection. The savings come at the cost of the shutdown option. It’s unfortunate if you actually have to leave in the morning, but the car did not charge overnight.

Without such facilities, remote shutdown is impossible; it would only be possible for entire streets at once, but not for the individual heat pump user in the neighborhood, unless they explicitly have the option.

I think that's a bit of modern luxury. When we were children, we were bathed once a week and otherwise used a washcloth, just as adults did not shower daily. Today, many adults shower daily, sometimes even multiple times, and children bathe much more often. In that case, a large hot water storage tank is quite sensible.

Mr. Kretschmann, is that you?

But first you need facilities that enable local throttling. Here, the basic supplier offers a cheaper tariff that can shut off your wallbox on demand with a small additional box connected via mobile network. The savings are then bought with the shut-off option. It’s annoying when you actually need to leave in the morning, but the car didn’t charge overnight. Without such facilities, remote shut-off is impossible; it would only be possible street by street for everyone, but not for the one heat pump user in the neighborhood unless they explicitly have the option.

At night, electricity is usually cheapest because few consumers are active. A shut-off during this period is therefore highly unlikely. A common e-car also charges at home with 11 kW. Even if you had basically driven the vehicle empty, it only needs 5-7 hours of charging time for a full charge. An hourly interruption hardly jeopardizes this extreme scenario, and throttling even less so. This could be possible via smart meter.

A shutdown during this period is therefore extremely unlikely.

Do you know? Here the municipality turns off the street lighting for the entire night, while father-in-law is charging his eMegane with 22 kW. Whether that will be only for a few hours or longer depends on the disaster scenario.

Smartmeter

It switches nothing.

He doesn't turn anything off.

My heat pump is already registered as a controllable consumer and is subject to blackout periods. One hour in the morning and twice one hour again in the afternoon. At night it doesn't matter. Look up load profiles for heat pumps and wallboxes.

The smart meter doesn't switch anything yet, correct. As long as the supplier has no direct access to consumers like heat pumps or wallboxes, the smart meter or the gateway is the logical component that can take over that.

The shutdown of the street lighting takes place for the sake of saving by the consumer (municipality) and not because the supplier cannot deliver. The supplier wants to deliver, otherwise he earns nothing.

The switching off of street lighting is done to save costs for the consumer (municipality) and not because the supplier cannot deliver. The supplier wants to deliver; otherwise, they earn nothing.

That is of course clear. Fortunately, we do not yet have an energy crisis. I just find it funny that this is happening simultaneously :)
