Why it matters: Utilities gain early influence over fusion’s rollout and access to future baseload power, while startups secure critical infrastructure and credibility. The deals reflect a material shift: fusion is no longer just science—it’s entering the utility planning cycle, with real sites, equity, and interconnection commitments now in play.
