With the expansion of renewable energy sources, the need for large storage systems is increasing. But operators are complaining about the cost burden of the construction subsidy (BKZ). A ruling by the Düsseldorf Higher Regional Court (Higher Regional Court) could provide clarity - but for now, there is uncertainty in the industry.

Profitability: For years, the battery storage industry has been fighting to cancel the construction subsidies with which it must participate in the investments of network operators. The costs can quickly run into the millions and prevent projects. Now a court ruled that the calculation method for battery storage systems was illegal. It remains to be clarified exactly how things will continue.

2024 is a key year for the storage industry. Florian Antwerpen, founder and Managing Director of Kyon Energy, provides insights into the most important developments.
