Legal Framework: An Overview

The foundation for dynamic energy tariffs can be found in various European and national regulations. The most relevant include:

• EU Electricity Market Directive: This directive establishes a unified legal framework for the European electricity market and promotes competition among energy suppliers.
• German Measurement and Grid Fee Ordinance (MessNetzV): This ordinance governs the billing of energy in Germany, including the use of intelligent metering systems.
• German Electricity Grid Fee Ordinance (StromNEV): This regulation sets the conditions for grid usage and enables billing based on different time periods.

These and other regulations form the legal basis that allows dynamic tariffs to be offered and grants smart meters the necessary access to electricity grids.

Dynamic Tariffs and the Housing Sector: Opportunities and Challenges

Dynamic tariffs present several benefits for the housing sector:

Opportunities:

• Cost Savings: Targeted charging of EVs during low-price periods can save costs for both tenants and landlords.
• Flexibility: Smart charging systems enable optimal adaptation of charging processes to fluctuating electricity prices.
• Sustainability: Dynamic tariffs encourage the use of renewable energy sources and contribute to grid stabilization.

Challenges:

The integration of e-mobility poses significant challenges for the housing industry. Dynamic tariffs offer a promising solution:

• Smart Charging: Coupling dynamic tariffs with intelligent charging systems allows for optimal management of EV charging in residential buildings.
• Load Management: During peak demand periods, EV electricity consumption can be automatically reduced to avoid grid overload.
• Tenant Appeal: The ability to charge EVs cost-effectively can be a crucial factor for tenants when choosing a property.

Future Outlook: The Potential of Dynamic Tariffs

The future of dynamic tariffs looks promising. As EV adoption grows and smart technologies advance, these tariff models will become increasingly attractive.

Key Developments:

• Mandatory Dynamic Tariffs: Starting in 2025, all electricity providers must offer customers with smart metering systems a dynamic tariff.
• Integration into Smart Home Systems: Dynamic tariffs can be seamlessly integrated into smart home systems for even more efficient energy consumption management.
• Enhanced Cost Savings: The combination of dynamic energy tariffs with algorithms that adapt vehicle charging curves to price dynamics unlocks greater savings potential.

Conclusion

Dynamic energy tariffs hold significant potential for reducing electricity costs and advancing the energy transition. The legal framework is in place, and technological progress continues. For the housing industry, these tariffs open new possibilities to enhance energy efficiency in buildings and increase tenant appeal.

ChargeIQ, in collaboration with the Fraunhofer Institute, will enable customers to combine their own dynamic energy tariff with an optimized charging curve, maximizing electricity cost savings.
