Promotion of e-mobility for new construction

No additional meter is needed. In the worst case, this can also be installed in the charging station. It is recognized by the tax office if necessary for billing.

Or as a calibrated meter on the DIN rail, if the WB does not come with one?

That's exactly what I don't understand. The wallboxes come with their own internal meter as far as I know. Still, our network provider (Westnetz) requires an additional meter and says that the internal one is not sufficient. I don't get it and am inclined to ignore it rather than invest 1200 EUR now for a big question mark.

Are you sure that Westnetz requires a separate meter? That only applies if you use the free e-mobility connection, right?

Yes , you are right. But that's what I'm concerned about. That at first (by phone) it was made to sound appealing to have the free eMobility connection installed directly and now I find out later that I would necessarily need an additional meter for that. Otherwise, the connection is of no use to me because I wouldn't be allowed to operate a wallbox later....

The question for me therefore is: - take the free connection from Westnetz and invest 1,200 EUR in the larger cabinet to be "future-proof," or - pay normally for the connection (around 700-800 EUR) to be independent and possibly later be forced to rebuild the meter cabinet for the installation of a meter to use the wallbox tariffs.

Oh, just saw now that you are the user who asked the question about Westnetze :D

Where do the 700-800 euros for the connection come from?
Do you mean the normal household electricity connection? Or is that the surcharge you pay if you indicate the operation of a wallbox when applying for the house connection?! That seems really high to me.

I think you should rather apply for your construction power normally. Indicate that you want to operate a wallbox later.
It probably won’t cost any extra.

If you ever want to have your own meter, you can still calculate whether it’s worth it
