PowerHouse Carlisle is a Pennsylvania Data Center Partners and PowerHouse Data Centers joint-venture campus near Carlisle, Pennsylvania. The developers describe three campuses, each with six buildings and a 450 MW substation, for 1.35 GW at full build and a possible expansion to 1.8 GW. Planned investment exceeds $15 billion, but the program remains prospective and phase delivery is not operating capacity. Customers, permits, utility milestones, water, financing and construction dates remain to be finalized.
