How many battery storage systems are there in Germany?

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.

What is a battery energy storage system?

Currently, most large battery systems (Battery Energy Storage Systems, or BESS) are powered by lithium-ion batteries. Such batteries are favoured especially due to their long life cycle and simple operation. Furthermore, alternative battery technologies are still in development and therefore not yet ready for market launch.

Will battery costs halve in Germany by 2035?

In less than five years, battery costs have more than halved in Germany, and there is no end in sight for further decreases. “The total cost of energy- storage systems should fall 50 to 70 percent by 2035 as a result of design advances, economies of scale, and streamlined processes,” forecasts business consultancy McKinsey.

What will Germany's energy storage industry look like in 2018?

Total sales are expected to rise around ten percent in 2018 to 5.1 billion euros, according to the German Energy Storage Association BVES. The German government wants to put the growth of the industry to use during the coal exit currently being planned by the country’s coal commission, by attracting battery cell production to coal mining areas.

How many stationary battery storage units were installed last year?

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.

Why is Germany launching a solar storage system?

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.” Home solar power units drove a massive rise in storage capacity in Germany last year.
