Amount and total load of grid losses [§ 23c (3) fig. 2 and 3 EnWG]

Data on grid losses on the distribution grid as an amount of energy and the temporal curve of the total load of grid losses.

The grid losses as an amount of energy were found by calculating the difference between feed and withdrawal.

The total amount of grid losses for Berlin's distribution grid in 2023 amounted to 394,903,875 kWh.
The amount is determined through calculations.

Total load of grid losses

The total load of grid losses is the load profile of the grid losses across all grid and voltage levels as 1/4h performance values. The performance values are determined through calculations.

Total load for non-load-profiled customers [§ 23c (3) fig. 3 EnWG]

Data on the total load for non-load-profiled customers and the temporal curve of the total load.

The total load for non-load-profiled customers (residual load) is the load profile of the total of all withdrawal points for standard load profile customers (SLP customers) as 1/4h performance values.

Load process

As the withdrawal points for SLP customers do not have registered performance measurement equipment, this load profile can only be determined through calculation.

The residual load can be found using the following calculation:

Residual load = grid load - grid losses - withdrawal load of load-profiled customers

Maximum withdrawal load and withdrawal from the upstream grid operator's grid [§ 23c (3) fig. 5 EnWG]

Data on the maximum withdrawal load and withdrawal from the upstream grid operator's grid.

The maximum withdrawal load is the maximum simultaneous output of all transfers from the grid run by the upstream network operator. The withdrawal from the upstream grid operator's grid is the total of all transfers (work).

The values are respectively determined either through measurement or calculation.

Maximum withdrawal load from the upstream grid operator's grid

The maximum withdrawal load for 2023 for the Berlin distribution grid was 1,701 MW. The maximum withdrawal load for 2023 occurred at 12:30 on 20 June 2023.

Withdrawal from the upstream grid operator's grid

The amount withdrawn in 2023 totalled 7,728,281,801 kWh.

Result of difference balancing [§ 23c (3) EnWG combined with § 12 (3) StromNEV]

Actual withdrawals by end consumers who are supplied according to a simplified process (standard load profile) deviate from the predictions in terms of the amount withdrawn and the time at which withdrawals were made.

The grid operator runs a difference balancing group for these deviations for all end consumers supplied according to the simplified process (standard load profile).

The result of the difference balancing for Stromnetz Berlin GmbH's distribution grid is published here pursuant to Section 12 (3) StromNZV.

Total feeds for each voltage level [§ 23c (3) fig. 6 EnWG]

Data on the total feeds for each voltage level and the temporal curve.

The total of all feeds for each voltage level is the total of feeds for the voltage level as an amount (work) in kWh, determined either through measurement (e.g. for the Renewable Energy Act over 500 kW) or by using feed profiles (e.g. minor power stations, Renewable Energy Act below 500 kW).
