Where can I find a subsidy for my battery? An overview.State subsidies reduce investment costs for energy storage and increase their cost-effectiveness. But what states and municipalities actually offer these subsidy programs? What are the requirements, and how high are the subsidies? We’ve put together an overview.
Varied subsidy landscape
The Germany-wide subsidy program “Renewable Energies – Storage” offered by the Kreditanstalt für Wiederaufbau (KfW) was discontinued on December 31, 2018. However, there are many new local subsidy programs to promote grid stabilization through the installation of distributed storage systems – so you can still benefit from a subsidy for your energy storage!
In particular, subsidy programs are currently (May 2019) being offered by Baden-Wuerttemberg, Bavaria, North Rhine-Westphalia, Saxony, and Thuringia. Subsidies in Brandenburg are limited in number, and the quota is currently filled. There are also numerous municipal programs. It’s a good idea to regularly check the subsidy database to find out about the latest developments.
In Baden-Wuerttemberg, the Ministry has earmarked €10 million to provide financial incentives for purchasing “grid-relevant battery storage” in conjunction with a photovoltaic (PV) system in order to reduce the load on distribution grids. The subsidy conditions were last updated on February 1, 2019.
Since 2015, the Free State of Bavaria has been subsidizing investments in energy storage as part of its 10,000 Houses program for energy-efficient building refurbishment and construction. According to a current statement by the Ministry of Economic Affairs, an additional, separate storage subsidy program is also being planned.
The state subsidizes PV systems and batteries for personal consumption of self-generated electricity through its Thüringer Aufbaubank. PV systems are subsidized only if 100 percent of the electricity produced is “self-consumed” and none is fed into the public grid. This is an excellent reason to purchase a large battery.
