New Regulations Drive the BESS Market in Germany – Opportunities and Challenges for 2025

The energy transition in Germany continues to accelerate, with regulatory changes implemented from March 2025 significantly transforming the market for Battery Energy Storage Systems (BESS). These new regulations present considerable opportunities while also posing notable challenges for market participants.

New Regulatory Framework from March 2025

From March 1, 2025, several key legislative measures have been introduced, strongly impacting the energy storage market:

• Peak Electricity Law (“Solar Peak Law”):
  
  
  • PV system operators must limit their feed-in capacity to 60% if they are not equipped with smart metering systems. This regulation creates substantial incentives for installing storage systems to efficiently use surplus electricity.
• EEG Amendments for Biogas Plants:
  
  
  • The operational hours for subsidized biogas plants are being reduced to encourage flexible operations. BESS can effectively store excess energy and facilitate optimized operating schedules.
  • Limits on subsidized operational quarter-hours and new requirements for dynamic controllability significantly increase the demand for battery storage.
• CHP Law Adjustments:
  
  
  • Although primarily targeting combined heat and power (CHP) systems, these changes indirectly open up new business opportunities for energy storage solutions, particularly in integrating renewable energy into district heating networks.

Impacts on the BESS Market

The new regulations significantly improve the attractiveness and economic viability of battery storage solutions:

• The accelerated smart meter rollout and the 60% feed-in limitation for PV systems notably increase profitability for self-consumption solutions involving storage.
• The shift towards quarter-hour contracts in the electricity market significantly enhances arbitrage opportunities, especially with highly volatile electricity prices.
• Biogas plants will increasingly require storage systems to operate economically and flexibly due to limited operational hours and heightened flexibility requirements.

Challenges Despite Regulatory Support

Despite these positive developments, significant complexities persist:

• Remote Control and Intelligent Metering Systems:
  
  
  • Enhanced obligations regarding remote control and smart meter integration significantly raise administrative and technical burdens on operators.
• Grid Connection Issues and Lengthy Approval Processes:
  
  
  • Regulatory simplifications notwithstanding, delays in grid connections and complicated approval processes continue to prolong project timelines.

Strategic Implications for Market Participants

Companies need to adjust their strategies to align with the new market realities:

• Emphasis on specialized solutions such as hybrid co-location projects (PV, biogas, wind combined with BESS).
• Partnerships with EPC companies (Engineering, Procurement, Construction) and network building are increasingly essential for executing larger projects and mitigating risks.
• Development of targeted ROI and economic viability tools for end customers to fully leverage new market conditions.

Medium-Term Developments and Strategic Opportunities

Medium-term expectations include:

• Market consolidation anticipated from mid-2026, with companies lacking clear differentiation likely to exit the market.
• Increased importance of specialized solutions, particularly for integrating BESS into complex energy systems (PV, wind, biogas).
• Growing necessity to develop internal project management competencies to be more involved in key projects and establish solid references.
