A Sam Altman-backed solar startup is officially ghosting the grid with land and solar + battery infrastructure to support hyperscalers. (Utility Dive)
Exowatt launched a new division, ExoRise, to build massive, fully off-grid power islands for data centers in the Southwest.
The tech: Exowatt’s proprietary “P3” units—modular solar arrays that store energy as heat, letting hyperscalers run 24/7 without tapping public transmission lines.Â
Exowatt says this off-grid approach solves the two biggest bottlenecks facing the industry: speed to power, and protecting locals from utility rate increases.
