What the sources say
No dated source found that confirms operation. Modo (17 September 2026) counts 168 MW at six Flevoland sites, which matches this list's Flevoland total only if FlevoBESS and Zeewolde are counted as operating. That is indirect support, not confirmation.; Status kept at construction because the last dated source (8 October 2025) says it was being built. It is probably running by now, but no source says so. Probable.
