ᐅ Connection Fees for Electricity – Why Do They Cost Money?

Hello,

today I found an offer from the local grid operator in my mailbox – a new grid connection contract for just under 3,000€.

I looked it up and the Federal Network Agency states:

A construction cost contribution may only be charged for the portion of the power demand that exceeds 30 kilowatts. Therefore, the standard residential electricity connection is exempt from construction cost contributions.

Now, I calculate it – the contract specifies a main fuse for the house connection of 3 x 63 amperes. At 400 volts per phase (correct, right?), that equals 75.6 kW?! The provider tells me this is a completely normal residential connection that always costs money.

So why does the Federal Network Agency say the above? Wikipedia says 30 kW is enough for four housing units... we are building a small single-family house.

Thanks 🙂

Are construction cost subsidies included in the 3000 euros (approximately 3200 USD)?

yes, 2x €0.00 🙁

The construction cost subsidy is not the expense for connecting the house to the street; rather, it is a grant to build or expand the downstream infrastructure according to the load requirements.

These are two completely different things.

And in my opinion, the formula is also incorrect.

P = U * I * √3 * cosφ

This is three-phase power, not three times direct current.

Phew, unfortunately, I don’t understand much about that... I’m not very familiar with electrical work. Could you please explain it to me in more detail?

The formula is correct, but it is 230V per phase.
