MaStR

The Market Master Data Register (MaStR) is a central database operated by the Federal Network Agency (Bundesnetzagentur) that records all relevant stakeholders and facilities in the German electricity and gas market. It is particularly significant for operators of solar systems.

Purpose of the MaStR:

Transparency: The MaStR ensures high transparency in the energy market by compiling all relevant data in one central location.
Billing: The data stored in the MaStR forms the basis for the billing of electricity quantities, especially for operators of renewable energies such as photovoltaics.
Monitoring the Energy Transition: The MaStR enables continuous monitoring of the development of renewable energies in Germany.
Network Calculation: Network operators use the data from the MaStR to ensure the stability and security of the electricity grid.

Importance for Photovoltaic Systems:

For operators of photovoltaic systems, registration in the MaStR is legally required. The registration includes, among other things:

Technical data of the system: Capacity, location, installation date
Owner data: Name, address
Feed-in information: Grid operator, feed-in point

Advantages of Registration:

Entitlement to Remuneration: Only registered systems are entitled to the legally defined remuneration for fed-in electricity.
Participation in the Energy Market: Registration is a prerequisite for participation in the energy market and enables, for example, direct marketing of electricity.
Proof of System Characteristics: Registration serves as proof of system characteristics and can be significant for financing or selling the system.

Conclusion:

The Market Master Data Register is an indispensable tool for all stakeholders in the German energy market, especially for operators of photovoltaic systems. By registering in the MaStR, transparency is increased, billing is facilitated, and the energy transition is actively supported.
