Meta Hyperion AI Data Center (Louisiana)

Meta's Richland Parish Data Center is the company's largest data center project to date in northeast Louisiana. Meta's own Richland Parish page describes a 4 million-square-foot site that will deliver over 2 GW of compute capacity to train future open-source large language models. Entergy's March 2026 agreement with Meta adds that the campus has the potential to scale up to 5 GW, while tying that expansion to new generation, transmission, storage, renewable, and possible nuclear infrastructure.

ADCI keeps the selected 5,000 MW value as a future full-campus power/compute envelope, not current delivered IT load. The energy record is mixed rather than nuclear-only: Entergy describes more than 5,200 MW of new gas-fired combined-cycle generation, about 240 miles of new 500 kV transmission, battery energy storage, nuclear uprates and exploration, and Meta support for up to 2,500 MW of additional solar. The site remains under construction, with public sources supporting a first-phase/early-operation target rather than current full-build operation.
