Mississippi Lands $20B xAI Data Centre: Jobs Surge but Pollution Fears Grow
The State of Mississippi announced a major investment: xAI will build a $20 billion data centre hub in Southaven, DeSoto County, as part of its Macrohard supercomputing initiative.
- Project details: xAI is investing $20 billion (£14.89 billion) to build a Macrohard/MACROHARDRR site in Southaven (DeSoto County) intended to be part of infrastructure supporting ‘the world’s largest supercomputer’ with 2 gigawatts of processing capacity; xAI trademarked Macrohard (filed 1 August 2025). The governor said the site is expected to be operational within the coming month and credited the deal with creating hundreds of long-term jobs plus thousands of contractor jobs.
- Background, incentives and local response: The project benefits from tax breaks approved in 2024 (exempting sales, franchise and corporate income taxes on the site and heavily reduced property tax rates approved by Southaven and DeSoto County). Local opposition includes the Safe and Sound Coalition (petition >900 signatures), and concerns from the NAACP and Southern Environmental Law Center about fumes and impacts on nearby predominantly Black neighbourhoods; the Mississippi Development Authority provided no immediate public estimate of the cost to the public purse.

Global Data Centers Poised for an ‘Investment Supercycle,’ JLL Says
JLL’s 2025 outlook projects global data center capacity will nearly double by 2030, driven primarily by AI demand and power-driven site selection changes.
- Main announcement/action: JLL forecasts global capacity rising from ~103 GW to 200 GW by 2030, requiring ~$3 trillion over the next five years (including $1.2 trillion in real estate asset value creation and $870 billion in new debt financing); current market fundamentals include ~97% global occupancy and ~77% of construction pipeline pre-committed, with lease rates forecast to grow at ~5% CAGR through 2030.
- Background and details: AI workloads expected to grow from ~25% (2025) to 50% by 2030 with an inflection around 2027 (inference surpasses training); power constraints are shifting siting to “power opportunistic” locations (e.g., Wisconsin, Indiana, Louisiana, Mississippi, rural Illinois, Pennsylvania), equipment lead times average 33 weeks, grid-connection timelines often >4 years, and financing is maturing (core strategies now ~25% of fundraising) amid an “infrastructure investment supercycle.”

Amazon Data Centers Aren’t Raising Your Electric Bills—They May Be Lowering Them
Amazon Web Services commissioned an E3 study finding its data centers generate surplus revenue and are not subsidized by other utility customers.
Main finding and scope: The E3 study projects $33,500/MW in surplus value in 2025 rising to $60,650/MW by 2030; for a typical 100‑MW data center this equates to $3.4 million in 2025 and ~$6.1 million in 2030. The study assessed multiple utility territories including PG&E, Dominion Energy, Entergy, and Umatilla Electric Cooperative, concluding revenues above regulated returns can fund grid modernization without shifting costs to residential ratepayers.
Partnerships, structures, and project details: AWS and utilities are using innovative models (e.g., NIPSCO GenCo: 3 GW investment with 2.4 GW for data centers and 600 MW reserved for grid reliability); NIPSCO projects ~$1 billion in cost savings returned as bill credits over a 15‑year duration. Other specifics include Entergy Mississippi’s $300 million Superpower Mississippi grid campaign, AWS’s >600 renewable projects (claimed to power 8.3 million U.S. homes), investments in nuclear and 11 solar-plus-battery projects, and AWS efficiency metrics (Graviton up to 60% less energy, Inferentia2 up to 50% better performance per watt, PUE 1.15 in 2024, 35% embodied carbon reduction).

Broadband Industry Likes New Non-Deployment Bill
Senators Roger Wicker (R-Miss.) and Shelley Moore Capito (R-W. Va.) introduced the SUCCESS for BEAD Act to ensure states use their full BEAD allocations and to allow specified “non-deployment” infrastructure and workforce uses tied to AI.
- Main action: The bill would allow states to spend remaining BEAD allocations on wholesale fiber lines, mobile wireless infrastructure, submarine cables and landing stations, workforce development, mapping, and permitting reform, while explicitly excluding data centers as eligible uses. The Commerce Department estimates about $21 billion of the $42.45 billion BEAD program is currently unallocated for deployment; states would be required to hold another round of bidding for wholesale or backbone projects.
- Background and additional details: The Trump administration rescinded approval for non-deployment activities in June and the President issued an executive order directing NTIA to produce a policy notice making states ineligible for non-deployment funds if they have “onerous” AI laws; NTIA Administrator Arielle Roth said the agency was still “operating under the assumption” states could use full allocations. The bill does not permit spending on adoption, affordability, or device/plan subsidies; the administration also canceled $2.75 billion in Digital Equity Act funding. Supporters include Fiber Broadband Association, INCOMPAS, WIA, USTelecom, Connected Nation, Competitive Carriers Association.

Wicker, Capito Introduce Bill to Ensure Use of Non-Deployment Funds
Sen. Roger Wicker and Sen. Shelley Moore Capito introduced legislation requiring states to use non-deployment funding from the Commerce Department’s BEAD program.
- Main action: The SUCCESS for BEAD Act would require states to “use all remaining amounts” from the $42.45 billion Commerce Department BEAD program, directing leftover non-deployment funds (about $21 billion expected to remain under updated rules) into a competitive subgrant program for eligible projects; the bill explicitly prohibits data center construction and lists allowed uses such as telecom workforce development, wholesale fiber, internet exchange points, and mobile wireless infrastructure.
- Implementation & background: The bill gives NTIA 30 days after enactment to provide guidance; states with workforce development boards may award funds without bidding; the NTIA earlier rescinded approval for non-deployment activities in June, and a Presidential executive order directs NTIA to issue a policy notice within 90 days to potentially withhold funds from states deemed to have “onerous” AI laws.

What to Do With Remaining BEAD Funds, a.k.a 'Non-Deployment'?
The National Telecommunications and Information Administration (NTIA) issued the BEAD Restructuring Policy Notice prioritizing lowest-cost bids, voiding previously approved state plans, and rescinding authorization for non-deployment activities.
- Main action and effects: NTIA’s June 6 BEAD Restructuring Policy Notice requires states to resubmit plans within 90 days, eliminates scoring criteria for labor practices, climate resilience, and affordability, and replaces multi-criteria evaluation with a single metric—total BEAD cost per location; NTIA now estimates roughly $21 billion in BEAD “savings” across 56 states and territories.
- Background and specifics: States had planned to use non-deployment funds for workforce development, digital literacy, telehealth, device subsidies, and community anchor institution connections (examples: Louisiana $510 million, Florida ~$200 million); litigation risk and Congressional pushback (bipartisan letters, proposed RECAPTURE Act) are active, and NTIA has promised guidance in early 2026. The draft White House executive order would link eligibility for remaining funds to state AI regulatory frameworks, adding a legal and political dimension.
