Grid tied storage system project financing options in Germany 2025

Can energy storage be used for grid relief and load shifting?

By comparison, 251 TWh was generated from renewable energies in 2023. In order to be able to use the electricity at times when consumption exceeds production, a rapid expansion of systems for storing electrical energy is required. The paper sees electricity storage primarily as short-term storage for grid relief and load shifting.

Can electricity storage systems be funded under the EEG?

Up to now, it has not been possible to receive funding under the EEG for electricity from electricity storage systems that are connected to the grid. As the electricity is stored from the grid, the storage volume includes a proportion of electricity from non-renewable energy sources.

How can electricity storage systems contribute to a climate-neutral electricity supply in 2035?

The aim of the strategy is to contribute to a “virtually climate-neutral” electricity supply in 2035. Due to the volatility of renewable energies, electricity storage systems play an important role in stabilising and flexibilising the electricity grid.

Why does Germany pay a construction cost subsidy?

This is intended to provide further financial relief. Companies that want to plan and install a battery storage system must pay the grid operators a construction cost subsidy for the expansion of the general grid. This subsidy varies greatly from region to region in Germany and cannot be reliably calculated in advance.

Is the electricity storage strategy a good idea?

The electricity storage strategy has been criticised by the industry for its lack of concrete targets and timetables. There are good ideas, but they are not supported by direct measures. Furthermore, electricity storage systems should continue to be legally categorised as systems for the generation and consumption of electricity.

How does Bess support Germany's energy transition?

By ensuring energy resilience, reliability, and sustainability, BESS aligns with Germany’s vision for a carbon-neutral future and sets a benchmark for the global energy transition. Enabling Germany's Energy Transition requires an economically sustainable model to attract necessary private capital.
