Notify us of the use of storage devices if the storage devices connected to the network can be charged through the network and the stored electricity can be transmitted back to the network. Notification is required to ensure the safety of the network connection and to provide the network operator with information on the equipment used in the network.
Storage device connection application
A connection application must be submitted if:
- A generating and/or storage installation is connected to the network for the first time;
- Storage installations are added to generating installations already connected to the network, thereby altering the conditions agreed in the network contract, such as the maximum capacity of the generating installations and/or the import capacity from the network and/or the export capacity into the network.

We will review the submitted application and contact you if necessary. If the application is compliant, we will prepare a connection offer for you.
Storage device registration application
A registration application must be submitted if:
- Storage installations are added to generating installations already connected to the network, where the conditions agreed in the network contract do not change.
The configuration protocol of the power-generating module must be submitted with the registration application if:
- When adding a storage installation, the existing inverter is replaced with a new one;
- A new inverter is added to the existing inverter.

We will review your submitted registration application. We will send you a revised network contract together with confirmation that the installation has been registered and can be put into use. We will inform you if, on the basis of the data provided in the application, it is not possible to register the installation and a connection application must be submitted.
Additional metering point for a storage device
An additional metering point may be required for a storage device if the electrical energy stored from the network cannot be clearly distinguished from other consumption. In such a case, calculation of the balance of electrical energy is not possible. In order to be able to apply for the calculation of the balance at the connection point, a separate metering point must be ordered in advance for the electricity storage device. The addition of an additional metering point is a chargeable service, and its price depends on the actual costs incurred.
To order a separate metering point for the storage device, please send the completed and digitally signed application form to [email protected].
