ᐅ Electrical Connection with E-Mobility: Should You Include It or Not?

Hello dear forum members, I am new here and this is my first question for you:

We are going to build a single-family house. The plot of land is already purchased, and now we need to order a power connection and construction power supply from Westnetz.

During the ordering process, there is an option to plan for e-mobility. You have two choices: one, to select a controllable connection according to §14, with a smart meter; or two, to choose a non-controllable connection, but you receive a substantial subsidy if you opt for the controllable connection.

I have tested all options:
Option 1: Power connection and construction power without e-mobility costs about €800 (approximately $870 USD).
Option 2: Power connection and construction power with e-mobility and controllable by Westnetz costs only €350 (about $380 USD). However, this is only because I specified an additional 22kW; otherwise, the connection would be completely free if you choose the controllable option.

Now my concerns and confusion...
If I take the controllable connection with 22kW, for example, a smart meter will be added later, which costs about €100 (around $110) per year.
If I do not choose e-mobility, the connection price is higher.
Presumably, electric vehicles will become more common in the future, so it might be better to opt for the controllable connection. My wife thinks maybe we should not do that.

What do you think? Should we go for the controllable e-mobility connection, or the non-controllable one (they will probably require a controllable connection later anyway)?

Or should we completely forgo this connection?

Many thanks in advance for your answers.

Best regards,
Elmar

What is the capacity of the non-controllable connection?

I wouldn’t want the utility company to be able to control my power supply. They are welcome to come by and inspect everything, but not control anything remotely.

If you plan to buy an electric car at some point, assuming you don’t have one already, you would simply get a wall box charger (which might only provide about 11kW). Of course, a sufficiently strong power cable can be installed underground during the construction phase and routed to the carport or garage.

I wouldn’t want the utility company to be able to control my electricity connection. They can certainly come by and check everything, but I don’t want remote control.

If you decide to buy an electric car in the future, assuming you don’t have one yet, you simply get a wall box charger (well, then you might only have 11kW). Of course, you can already lay a sufficiently thick power cable underground during the construction phase and have it end at the carport or garage.

Yesterday, I applied for a controllable connection for EV charging and specified 22kW, for a total of 2 x 11kW charging stations.
The only attractive part was the waived connection fee.
I can still cancel the contract, but what do I need to specify in the new contract to ensure they include a circuit breaker panel designed for higher power capacity right away?

Well, you need to ask your electricity provider what options they offer. For example, I have a 43kW household connection without requesting anything special, and that is more common than not.

With 400V 3x32 Ampere, you can operate a 22kW charging station.
As @Mycraft suggested, just check with your utility provider to find out which power levels they offer for residential connections.
It’s better to choose a slightly higher capacity. In the future, it will probably become more difficult to obtain higher connection capacities. Also, you surely don’t want to dig up your outdoor area and walkway again in a few years.
Since we needed more power and wanted some reserve, we went with a 125A protection, which equals 80kW.
For your situation, 43kW–64kW makes sense.
Have you looked into what the control system means at Westnetz? E-mobility is only available at certain times, etc.
I would definitely recommend choosing an uncontrolled connection.

I left it as is and received confirmation for a connection with 3x80A, which is about 55kW. Normally, this size would cost 1170€ with Westnetz including a temporary construction power connection, but because I chose the controllable electric vehicle connection, I only pay 350€ for everything. An EV charging station is not mandatory later on; it’s only this agreement that makes it so affordable now. Let’s see what the future will bring.
