Publication pursuant to the Regulations governing Energy Grid Access (StromNZV)
StromNZV is a set of regulations based on the EnWG (Energiewirtschaftsgesetz - Energy Industry Act). It regulates the conditions for access to the electricity supply grids for electrical energy feeds into feed points and the simultaneous withdrawal of electrical energy at withdrawal points which are geographically at some distance from the feed point.
All downloads are available in German language only.
Result of difference balancing
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supplied according to a simplified process (standard load profile) deviate from the predictions in terms of the amount withdrawn and the time at which withdrawals were made.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.
Annual maximum load and load curve
Data on the annual maximum load on the distribution grid and the temporal curve for the load.
The annual maximum load is the maximum performance value that occurred on a grid across all voltage levels in a given year.
The annual maximum load for Berlin's distribution grid in 2018 was 2,284 MW.
The annual maximum load was reached on 1 March 2018 at 19:00.
Amount and total load of grid losses
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 2018 amounted to 406,493.582 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 timetable predictions for SLP customers
Data on the total load timetable predictions for SLP customers and the temporal curve of the total load.
The total of the timetable predictions for standard load profile (SLP customers) is the load profile calculated using the supplier timetables for their respective SLP customers. The timetables underpin the annual output predictions and the load profiles assigned to each SLP customer.
Timetable prediction process
The summation of the timetables of the suppliers to SLP customers in Stromnetz Berlin GmbH's distribution grid is laid out in the following file, Total Load Timetable Predictions for SLP Customers.
Total load for non-load-profiled customers (residual load)
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.
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
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 2018 for the Berlin distribution grid was 1,762 MW. The maximum withdrawal load for 2018 occurred at 19:15 on 31 July 2018.
Withdrawal from the upstream grid operator's grid
The amount withdrawn in 2018 totalled 9,744,380,883 kWh.
The temporal curve for the Berlin distribution grid is calculated using measurements and profiles corresponding to the amounts.
Amount and median price of energy losses
Data on the amount and price of energy losses.
Energy losses are the amount of energy to cover grid losses across all grid and voltage levels in kWh.
Amount of energy losses
The total amount of energy losses across all voltage levels for the Berlin distribution grid in 2018 totalled: 406,493,582 kWh.
Median price of energy losses
The median price of energy losses in 2018 was: 3.116 ct/kWh.
The median price is found using all procurement to cover the losses in relation to the amount across all grid and voltage levels.
Total feeds for each voltage level
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).
