CATL Retains Top AAA Battery Storage Bankability Rating for Second Straight Quarter

The significance lies less in the top grade than in the methodology behind it: PV Tech Research is explicitly weighting supplier strength over any single product metric, which reframes bankability as a balance-sheet and execution question rather than a spec-sheet one. That favors established, diversified manufacturers over specialists and shapes how storage buyers and financiers screen counterparties. Whether the ratings framework keeps rewarding scale over product-level differentiation is the open question to watch.
