Market master data register for balcony power plants

We will guide you step by step through the registration of your balcony power plant in the market master data register. The Market master data register is a database maintained by the Federal Network Agency that lists all power generation plants and, for example, a source for the green power index is.

You need about 10 minutes to register. The most convenient way to register is on a desktop computer/notebook.

Step 1: Create a user account

Step 2: Registration as an operator

In this step you register as a system operator. This is the preselection as soon as you have clicked the link from the confirmation email.

Information you need:

• Address
• contact details

On the second page of the form, identifiers are required that are not available for a balcony power plant/connector solar. Since the system is not intended to be fed into the power grid, no income is generated, which is why the question of the independence of the system operator should make no difference.

Step 3: Registration of the installation

At the end of step 3 it will be displayed that you are now a market player who has an identifier in the market master data register. In the last step, your small power plant is assigned to this identifier.

Information you need (page 1):

• Type of unit: "Electricity generation"
• Type of power generation: "Solar radiant energy"
• Display name of the unit in the MaStR: Your creativity will be publicly visible!

Information you need (page 2):
