The transition of battery energy storage systems (BESS) from development to operations remains fraught with technical gaps and communication breakdowns.

We hear from the BESS lead at RWE Renewables Europe & Australia ahead of the Energy Storage Summit Germany 2026, discussing the major trends, challenges and opportunities in the country’s grid-scale storage market. 

RWE Clean Energy has commissioned the Stoneridge Solar PV project in Texas, adding 200MW of solar PV and 100MW/200MWh BESS to its operational portfolio.

Power generation firm RWE has put a BESS in the Netherlands into commercial operation, its first that is capable of providing inertia to the grid.

The industry still has a lot of work to do on urban project development and navigating local permitting challenges, a senior executive of US developer-IPP RWE Clean Energy told Energy-Storage.news.
