Louisiana AI Data Center Power Boom: Meta Phase 2 Triples Gas Plant Demand Under "Lightning Amendment"

The scale of Meta's Hyperion AI data center in Richland Parish, Louisiana, is expanding at an unprecedented rate, igniting intense legal battles over ratepayer exposure, environmental impact, and regulatory fast-tracking.

While Meta Phase 1 (Docket U-37425) was approved by the Louisiana Public Service Commission (LPSC) in August 2025 (authorizing three new natural gas combined-cycle plants), Entergy Louisiana has dramatically escalated its plans to serve Meta's expanding footprint.

Meta Phase 2 ("Project Evest") and the 5,200 MW Gas Surge

On March 27, 2026, Entergy Louisiana filed its application for Meta Phase 2 (Docket U-37882), proposing a massive infrastructure expansion to support Meta's growing AI campus. The proposal includes:

  • Seven additional natural gas combined-cycle power plants totaling more than 5,200 MW of new gas-fired capacity (four located in Richland Parish, three in Point Coupee Parish).
  • Roughly 240 miles of new 500kV high-voltage transmission lines and a new $550 million transmission corridor.
  • Battery storage installations at three separate locations, nuclear uprates, and up to 2,500 MW of Meta-funded renewable energy.

When combined with Phase 1, Entergy plans to build ten total gas-fired power plants totaling over 7,500 MW of capacity to serve a single hyperscaler campus. For perspective, this is enough electricity to power the city of New Orleans' peak annual demand six times over.

The "Lightning Amendment" and Ratepayer Backlash

This massive Phase 2 application is the first project submitted under the LPSC's newly adopted Lightning Amendment (also known as the Lightning Initiative). This regulatory fast-track framework allows Entergy Louisiana to bypass traditional competitive bidding requirements and long-term market assessments for lower-cost alternatives, aiming to compress approvals to a rapid eight-month timeline.

On August 4, 2026, a coalition of consumer advocacy and environmental groups—including the Alliance for Affordable Energy, the Union of Concerned Scientists (UCS), and The Lens NOLA—officially launched a joint legal challenge to Entergy's Phase 2 proposal.

The core ratepayer protection concerns are:

  1. Long-Term Stranded Asset Risk: Meta's contract with Entergy is for 15 years, but the operational lifespan of combined-cycle gas plants exceeds 30 years. If Meta decides not to renew its contract or exits the site, Louisiana's 1.1 million captive residential ratepayers could get stuck footing the bill for billions of dollars in stranded generating assets.1
  2. Fuel and Operating Cost Pass-Throughs: While Entergy and Meta claim Meta is covering its full cost of service—promising $2 billion in net customer savings over 20 years—critics argue that volatile natural gas fuel costs and ongoing operations and maintenance (O&M) expenses are not fully insulated from residential bills.
  3. Bypassing Competitive Vetting: By using the "Lightning Amendment" to bypass competitive bidding, regulators are prevented from testing whether cheaper, cleaner resource combinations (such as solar-plus-storage or regional market purchases) could meet the load with less risk.

This battle has reached the highest levels of state government. In late June 2026, Governor Jeff Landry publicly warned state regulators not to let Entergy "take advantage" of ordinary ratepayers, emphasizing that the utility promised no costs would be passed onto residential bills. The LPSC's upcoming hearings on Docket U-37882 will represent a critical test of whether the "Lightning Amendment" provides genuine ratepayer firewalls or serves as a vehicle for massive utility capital-expenditure rate-basing.

Verbatim Quotes

From the Union of Concerned Scientists' August 2026 analysis:

"In April 2026, Louisiana’s largest utility company, Entergy Louisiana, filed an application with state regulators to build seven additional gas-fired power plants to serve an expansion of the AI data center being built by Meta in Richland Parish... Entergy and Meta are claiming that a single data center needs a total of 10 new gas plants... For perspective, 7,540 MW is enough to power the entire city of New Orleans’ annual peak demand — six times over."

From Louisiana Radio Network's reporting on the August 4, 2026 coalition challenge:

"A trio of groups is joining forces in challenging Entergy Louisiana’s proposal to build seven new gas plants for Meta’s new AI data center in Richland Parish through Governor Landry’s 'Lightning Speed' initiative."

  1. An instance of Guaranteed utility returns shift the stranded-asset risk of speculative AI grids onto captive ratepayers. — Captive residential ratepayers face immense financial exposure because the long-term stranded asset risk of building gas plants specifically for Meta's speculative demand falls back onto them. ↩︎
