Technical FAQs 4

How does energy storage work in the EU?

The main energy storage method in the EU is by far 'pumped storage hydropower', which works by pumping water into reservoirs when there is an electricity surplus in the grid - for example on a sunny or windy day - and releasing it when more energy is needed.

Is there a market for large-scale battery storage in Central Europe?

In many countries in Central Europe, the market for large-scale battery storage is growing rapidly. The drivers are diverse, but there are still obstacles, as Eliza Stefan, Sales Manager BESS for Central & Eastern Europe, Jinko EES, points out.

How can solar PV and battery storage be used in Germany?

According to International Energy Agency (IEA), in Germany, storage deployment is encouraged through innovation auctions, which reward the combination of renewables and storage. All successful bids in 2021 and 2022, totaling over 1 GW of installed capacity, were projects combining solar PV with battery storage.

How many solar storage systems are installed in Germany in 2021?

According to the German solar energy group BSW, about 141,000 new solar storage systems were installed in 2021 by German households, reaching the cumulative installation 413,000 units across the country.
