If you operate a heat pump, wallbox, or another steerable device, you can benefit from reduced grid fees. This helps support the energy transition and maintain grid stability.
What is §14a EnWG?
§14a EnWG regulates the integration and control of steerable devices into the electricity grid.
Goal: Ensure grid stability, especially with the growing use of EVs and heat pumps.
Since 01.01.2024, new devices (> 4.2 kW) must be reported to the grid operator and be controllable.
The grid operator may temporarily reduce power or shift operation if the grid is overloaded.
Devices installed before 01.01.2024 can participate voluntarily. Switching back to the old regulation is not possible.
⚡ Which devices are considered controllable?
Controllable devices are permanently installed and centrally controllable, for example:
Wallboxes for your EV
Heat pumps (including auxiliary or emergency heaters)
Energy storage/battery systems
Fixed air conditioning systems
Power: > 4.2 kW, connected to the low-voltage grid.
💚 Benefits for You – Modules and Grid Fee Reduction
If your device is controllable, you receive reduced grid fees, which are automatically applied to your invoice.
Module 1 – Flat Rate
Fixed annual reduction, regardless of actual control
No separate meter required
Amount varies by region, depending on your local grid operator (e.g. price sheet, 2025, e-netz Südhessen AG, link here: https://www.e-netz-suedhessen.de/fileadmin/download/preisblatt_strom.pdf)
Standard module if no other module is chosen
Module 2 – Usage-Based Reduction
Reduces grid energy price to 40%
Basic grid fee is waived
Requires a separate meter for the controllable device
Must be actively chosen
Module 3 – Time-Variable Grid Fees
Only available in combination with Module 1
Energy prices are divided into three time tariffs: High (peak), Standard (mid), Low (off-peak) - each grid operator decides their own tariff times.
Requires a smart meter
Encourages shifting consumption to cheaper times and relieves the grid
Reduction is applied in addition to the Module 1 flat rate
🛠️ How to Apply for Grid Fee Reduction
Contact your grid operator – your device is registered as steerable with the grid operator either by you or by the installer.
Or via your electricity supplier (e.g., Ostrom) – we request the desired module with the grid operator.
Price Sheet – the grid operator reviews the request and sends back the official price sheet with the applicable grid fee reduction.
Billing – reductions are automatically applied to your electricity invoice.
💡 Price Sheets
The amount of reduced grid fees is set each year in the official price sheets of your local grid operator.
