A planned 2 GW, natural gas-powered AI campus on 568 acres at Longfellow Ranch in Pecos County, West Texas, announced by AI company Poolside in October 2025 with CoreWeave as anchor tenant for a first 250 MW phase. In April 2026 DCD, citing the Financial Times, reported the CoreWeave deal had fallen apart and Poolside was seeking new partners. Pecos County considered a tax abatement for Poolside in November 2025.
