Prometheus WY-2 is Prometheus Hyperscale’s proposed Casper-area campus in Wyoming. Developer and state materials describe up to 1.5 GW of IT-ready capacity over multiple phases, backed by onsite natural-gas generation and a carbon-capture partnership, with at least $500 million of initial investment. Wyoming economic-development records also identify the Casper project as certified for the state data center sales-tax exemption. The 1.5 GW figure is future phased capacity, not operating load, and first-power, permits, customer commitments and carbon performance remain prospective.
