How much a battery storage system can earn depends on the markets it operates in.

​

To quantify this, we simulate the revenues of a representative 10 MW / 20 MWh grey standalone storage every month: once for each individual market and once with cross-market optimization by suena energy.

Results are available for Germany from January 2026 and for Poland from August 2026. The figures can be explored by country, month and comparison market.
