German Energy Sector Faces Challenges with Grid Fees and Flexible Connection Agreements as Battery Storage Projects Expand

The discussion centers on the challenges and opportunities within Germany's energy sector, particularly focusing on grid fees, access issues, and Flexible Connection Agreements (FCAs). Kyon Energy is a project developer with nine active projects in Germany. The company highlights changes in legislation affecting business models for battery storage systems, such as the end of Vermiedene Netzentgelte (Avoided Grid Tariffs), which previously allowed batteries to profit from demand peaks. Current projects are exempt from grid tariffs under paragraph 118 of the Energy Industry Act until 2029 but face potential legal disputes over connection surcharges. FCAs offer solutions by allowing restricted operation during peak times; however, they can reduce profitability significantly—up to 30%, potentially undermining business cases for battery investments. The speaker advocates against static restrictions imposed by grid operators and suggests more flexible agreements that allow market-based redispatching to ensure efficient system operations without compromising revenue streams or discouraging investment in storage capacity expansion.

To provide much-needed flexibility to the increasingly renewables-dominated power systems, energy storage requires suitable market schemes and fair market conditions. Although authorities are increasingly recognizing the benefits of storage, regulations are still lagging behind. Lack of contracted revenues, barriers to co-location with PV, and an uneven playing field for European cleantech manufacturers are only a few examples of where storage needs regulatory action.In this panel, experts discuss the most exciting developments in regulatory frameworks, their suitability for unlocking the full potential of energy storage as well as the improvements that need to be made.

While predictive maintenance has become a well-known concept in battery energy storage, the next step is predictive operation. This approach aims not only to prevent failures, but also to continuously optimize system operation in real time. The goal is to maximize the performance, efficiency and lifetime of the existing hardware in each specific use case. Predictive operation extends beyond the battery cells themselves: Adaptive thermal management, intelligent inverter control and optimal coordination of power electronics all play a crucial role. By anticipating system behavior under different operating scenarios, predictive operation enables asset owners and operators to extract greater value from their storage systems while improving reliability and integration with renewable generation. This session will highlight the latest methods, control strategies and demonstration results that bring predictive operation from research into practice.
