Corscale Data Centers is planning Highlands West, a campus of three one-story buildings of 409,500 sq ft each on the 228-acre former Dauphin Highlands Golf Course in Swatara Township and Steelton, Dauphin County. The Dauphin County General Authority approved the $45.6 million sale to a Provident Realty entity on Aug. 20, 2025, and the course closed on Oct. 12, 2026. Swatara Township approved community benefits agreements worth $120.3 million in October 2026, while residents continue to raise noise, water and grid concerns. Corscale says it will spend $10.5 billion across Highlands West and the nearby Highlands East complex; no construction start or completion date is published.
Pennsylvania House Bill 1834 (tracked in the AI Data Center Legislation Tracker) mandates annual public reporting of electricity demand (MW/MWh), peak water consumption (gallons per day), cooling system design, and backup diesel generator emissions for large data centers operating in the Commonwealth.
Pennsylvania Senate Bill 937 directs the Pennsylvania Public Utility Commission (PUC) to establish dedicated large-load tariffs for hyperscale AI data centers above 50 MW so residential ratepayers do not subsidize transmission upgrades or PJM capacity auction surges.
