German Stationary Battery Storage Increases 50 Percent in One Year

According to preliminary numbers from the German Solar Industry Association (BSW Solar), there were 1.8 billion installed battery storage systems in Germany at the end of last year. They had a capacity 19 gigawatt hours (GWh), enough to cover the daily electricity consumption of two million two-person households. 

Almost 600,000 new stationary battery storage units were installed last year. That amounted to an annual increase of just under 50 percent. 

There were 15.4 GWh of capacity installed in private homes, much of it to use self-generated photovoltaic electricity. 

“Germany is the largest market for stationary battery storage systems in Europe and offers enormous investment opportunities along the entire value chain,” says a Germany Trade & Invest solar power specialist. “The great expansion of renewable energies is driving this dynamic, particularly for large-scale storage systems, which are currently so lucrative that they usually pay for themselves within a few years. The German government is planning further measures to make the integration of storage systems smooth and effective. This is a decisive step towards driving forward the expansion of renewable energies in an economic and system-friendly manner.”
