Competitive landscape
Edge: Vertical stack — U.S. factory, owned install motion, retail energy + utility capacity models — priced by growth investors as national grid infrastructure after back-to-back $1B rounds.
Base Power competes with residential storage incumbents and utility-scale BESS on the job of firm capacity — but sells a home-level form factor with software aggregation. Differentiation is install velocity, battery size class, and dual retail/utility GTM; risks are manufacturing scale and geographic expansion.
-
Tesla Energy direct

-
Sunrun adjacent
