The situation

Three weeks after the meeting of stop 02, the grid operator's offer arrives: four pages and one table. The developer reads it line by line, because every line changes the business case or the timeline.

The offer is composed in the structure German distribution grid operators use; the amounts are illustrative, the rules behind them are real.

The questionWhat does each line of the offer mean, and which lines decide what the hub costs and when it opens?

Guess firstWhich single number in the offer drives both the one-off contribution and the yearly grid fees?RevealHide

The agreed capacity in kilowatts. The construction cost contribution is priced per kilowatt, and so is the capacity part of the grid fees. Lowering the peak with load management or a battery lowers both.

What you are looking at

In Germany, a grid operator must connect anyone who asks, at conditions that are appropriate, non-discriminatory and transparent, and it must state those conditions; the offer is where it does. EU law adds that the operator cooperates with whoever builds charge points on a non-discriminatory basis. The result is a document with a fixed structure: the technical lines say where and how the hub connects, the commercial lines what it pays once and every year.

Select the numbered lines to see what each one decides.

Medium-voltage connection, 20 kV, composed offerThe offer, line by line

Eighteen lines, in the order the grid operator sends them: the technical part first, then money, then time and conditions.

  1. Line 1The clock starts

    Capacity is reserved only once the connection agreement is signed. After three months the offer lapses, with its prices and its place in the queue.

A composed offer in the structure German distribution grid operators use; the prices are illustrative. The duty to connect and to state the conditions follows § 17 EnWG, the two zones of the grid fees § 17 StromNEV, the contribution the Bundesnetzagentur's position paper of 2024, the customer station VDE-AR-N 4110.

every year, at 10% utilisation

Computed from the offer. The one-off items are about 445 k EUR; the grid fees are about 6.8 ct per kWh at 10% utilisation, a cost that stop 08 folded into the energy price.

Where the numbers come from

Three rules stand behind the commercial lines:

  • The contribution. Above low voltage, German grid operators may ask for a one-off contribution to the upstream grid, computed under the capacity price model of the Bundesnetzagentur's position paper: the agreed capacity times a capacity price of the network level. It is not refunded if the hub later uses less.
  • The . The regulation on grid charges sets a capacity price per kilowatt of the year's peak and an energy price per kilowatt-hour, in two zones divided at 2,500  a year. A hub at 10% sits far below that line, so it pays the low capacity price and the high energy price.
  • The station. The customer's station must meet the technical connection rules for , which set protection, reactive power and the proof the customer has to deliver before energisation.

Why the agreed capacity is the lever

Every per-kilowatt line follows the agreed capacity, and the capacity part of the grid fees follows the highest quarter hour of the year. A site that caps its peak pays less twice. That is why load management and a battery beside the chargers are grid-fee decisions as much as technical ones: 1,000 kW agreed instead of 1,200 kW would cut the contribution by 19,480 EUR and the capacity charge by 4,622 EUR a year.

What the offer does not decide

The energy price is not in it: the hub buys its electricity from a supplier under a separate contract (stop 03), and the grid fees come on top of that price. The building permit is the authority's, the station is the customer's, and whether the hub ever pays back is the subject of stop 08. The offer decides one thing above all: that there is a date, and a capacity, to plan around.

Check your understanding

3 questions. Answer all of them to complete this stop. Each answer explains itself.

01Question 1 of 3

The offer prices the connection charge and the capacity part of the grid fees per kilowatt. What lowers both?

02Question 2 of 3

The hub uses 1.05 GWh a year with a peak of 1,200 kW. Which grid fee zone applies?

03Question 3 of 3

Which cost of the connection is not paid to the grid operator at all?
