Louisiana data center power — the grid build behind the AI boom

The three utilities and what they're building

Entergy Louisiana, a subsidiary of Entergy Corporation, serves the northeast and southeast portions of the state and is anchoring the Meta Hyperion build in Richland Parish with a publicly disclosed plan to add 7–10 new natural gas generating units — the largest single industrial buildout in the company's recent history.

AEP SWEPCO, the Southwestern Electric Power Company subsidiary of American Electric Power, serves the northwest Louisiana corridor anchored on Shreveport-Bossier and is the utility of record for Amazon's $12B Caddo + Bossier campuses. SWEPCO's structure recovers all project-specific substation, transmission, and specialized-equipment costs from Amazon under LPSC oversight.

Cleco Power covers central Louisiana including Rapides Parish (Alexandria) and the Acadiana corridor and is the contingent provider for several emerging mid-tier AI campuses tied to existing industrial sites.

How the tariffs protect residential ratepayers

All three utilities operate under Louisiana Public Service Commission (LPSC) jurisdiction. The LPSC has stipulated in approving recent data-center load that any incremental generation, transmission, or specialized equipment cost is recovered from the data-center customer through dedicated tariffs — not socialized across residential and small commercial classes.

Entergy publicly attributes roughly $2.8 billion in cumulative customer savings to Louisiana data-center customer agreements signed in 2024–2025 across Arkansas, Louisiana, and Mississippi.

The capacity math

Meta Hyperion alone is publicly projected to use up to 5 GW of computational power at full scale — comparable to ~3.5–4 million typical US homes.

Amazon's Caddo/Bossier campuses, Hut 8 River Bend, and Applied Digital's central Louisiana sites layer on top, putting Louisiana's total announced AI data-center load above 8 GW of peak demand against a state-wide generation fleet of roughly 30 GW in 2025.

The single largest near-term risk to operators is *interconnection queue position* — the LPSC docket calendar and MISO/SPP interconnection studies, not the construction schedule, set the actual commissioning date.
