From mini-batteries for rental apartments to giant storage systems for three million households: Batteries are increasingly becoming a central component of Germany's energy transition. Precisely now, the industry is concerned that this boom could be artificially curbed. “A discussion about restrictions could make the financing of new installations impossible,” warns Marie-Sophie Braun.

Next year, the Federal Network Agency plans to develop rules for flexible grid connection contracts. Eon is already leading the way with a standard FCA. However, the plan is met with unease in the energy sector. Experts also warn in an analysis against grid operators having too much power in FCA design in many EU member states and are proposing counter-suggestions.

The expansion of battery storage systems continues in Germany. With two new large-scale storage facilities, Kyon Energy is strengthening its presence in the market for grid- and market-serving flexibility options, according to the company.
