Prometheus Hyperscale Pecos Campus

Last updated

Pre-construction

A proposed hyperscale campus in Reeves County near Pecos, planned by Prometheus Hyperscale with Istmo Energy for 1.5 GW of Phase 1 IT capacity and a path to about 2.5 GW. The design runs the first phase behind its own generation rather than through the ERCOT queue. No binding tenant has been announced and no construction has started.
