What is battery role migration?

The economic transformation of the AI-DC battery from single-purpose backup asset (R1) into a multi-purpose grid resource covering R1 through R6. Each stage is additive; the same physical battery can perform multiple roles simultaneously.

Which vendors matter at each stage?

R1-R2: UPS OEMs (Vertiv, Schneider, Eaton, ABB, Delta, LiteOn). R3-R5: hall BESS integrators (Fluence, Tesla Megapack, Wärtsilä, Powin, EVLO). R5 market access: DER aggregators (Voltus, CPower, Enel X, Autogrid). R6: grid-forming specialists (Tesla, EVLO, Wärtsilä, SMA, Sungrow).

What is the killer investment question?

Which R-stage is the target vendor's revenue anchored to. An R1-only UPS OEM earns different multiples from Fluence or Tesla Megapack at R3-R5 or a grid-forming specialist at R6. Screen R-stage exposure first.
