Metering Point Operation Law

The Metering Point Operation Act (MsbG) is a German federal law that regulates the framework conditions for the operation of metering points in the electricity grid. It also has significant impacts on the field of photovoltaics.

Key Aspects of the MsbG for Photovoltaics:

• Smart Metering Systems (iMSys): The MsbG mandates the use of smart metering systems for certain consumer groups, including many operators of solar systems. These systems enable more detailed recording of electricity generation and consumption.
• Self-Consumption: For plant operators with their own consumers, the MsbG provides the opportunity to directly consume the self-generated electricity, thus optimizing the feed-in tariff.
• Grid-Friendly Functions: Smart metering systems can perform grid-friendly functions, such as controlling charging processes for electric vehicles or participating in balancing energy markets. This can be particularly relevant for larger photovoltaic systems.
• Data Transmission: The MsbG regulates the transmission of metering data to various market participants, such as grid operators and energy suppliers. This data is also important for billing electricity quantities and feed-in tariff settlement.

Impacts on Photovoltaic Systems:

• Increased Flexibility: With more detailed metering data and the ability to control self-consumption, operators of photovoltaic systems can operate their systems more flexibly and thus increase their economic viability.
• Participation in New Business Models: Smart metering systems enable participation in new business models, such as virtual power plants or direct marketing of electricity.
• Increased Transparency: The transparency required by the MsbG regarding metering data allows plant operators to better understand and optimize their own electricity consumption.

Conclusion:

The Metering Point Operation Act has a significant impact on the operation of photovoltaic systems. By introducing smart metering systems and promoting self-consumption, new opportunities are opened for plant operators. At the same time, the MsbG ensures that the energy transition is designed efficiently and transparently.
