### English
* **Critical Market Design:** Industry experts highlight that Germany's upcoming capacity market design is essential for the viability of Battery Energy Storage Systems (BESS).
* **Avoiding Past Models:** Elisabeth Giesemann (Fluence) warned against modeling future energy security on outdated systems, advocating for a design that reflects modern, digital technological capabilities.
* **Technological Neutrality Concerns:** Sonja Risteska (SolarPower Europe) noted that supposedly "technology-neutral" auctions often inadvertently disadvantage batteries due to complex, biased criteria.
* **De-rating Factor Hurdles:** Current market mechanisms often use "de-rating factors" that restrict the revenue potential of batteries, undermining the business case for new storage investments.
* **Lessons from Poland:** Poland's capacity market serves as a cautionary tale; BESS contract awards dropped significantly from 2.5GW in 2024 to 685MW in 2025 due to restrictive policy changes.
* **Investment Security:** Experts argue that a well-structured capacity market is necessary to provide the investment security needed to replace traditional fossil-fuel energy sources.
