  Marana Rejects Data Center Referendum Petitions; Withdrawal Request Follows

  The Town of Marana has determined that referendum petitions filed to challenge a data center rezoning do not meet Arizona legal requirements.

  • Petitions invalid due to missing legal description: The Town determined the two petitions filed by Arizonans for Responsible Development (committee sponsored by Worker Power) lacked the required legal description of the properties; each petition contained about 2,800 signatures but failed to meet statutory form requirements. The committee, via Barton Mendez Soto PLLC, submitted a written request to withdraw the petitions on Feb. 17 stating it retracts signatures and acknowledged the petitions were invalid because they omitted the title and text on petition sheets.
  • Administrative process and timing: The Town states it cannot withdraw petitions once filed and must complete its review; the Marana Town Clerk has 20 business days to verify signature minimums before forwarding to the Pima County Recorder’s Office. The contested rezoning was approved unanimously by the Marana Town Council on Jan. 6, and under Town code referendums must be filed within 30 days of adoption, preventing refiling of a referendum for this decision.

  Data Centers Face Growing Policy Headwinds

  Jefferies’ Washington Strategy team published a note analyzing how growing political opposition to data center expansion could translate into policy action.

  • Main announcement/analysis: Jefferies outlines bipartisan scrutiny of data center growth (including the Trump Administration, Senator Bernie Sanders, and Senator Richard Blumenthal) and reports that six states have proposed some form of data center moratorium with several measures extending through late 2029; Microsoft has launched a “Community-First AI Infrastructure” plan and pledged to cover incremental electricity costs for consumers in areas where Microsoft is building data centers.
  • Background and policy levers: The note catalogs potential policy responses including federal permitting/energy dominance changes (e.g., easing Bureau of Land Management permitting), cost allocation moves like Ohio’s rule to require large power users to cover 85 percent of capacity costs, state tax incentive reform, expanded consumer energy support or electricity price caps, DOE asking FERC to develop grid connection rules, and the pending Prince William Digital Gateway court hearing scheduled for February 23–24. This is an analytical note referencing existing announcements and policy proposals rather than a single new government policy announcement.

  Dynamic Load Model for Data Centers with Pattern-Consistent Calibration

  Siyu Lu and co-authors have posted a paper to arXiv presenting a new dynamic load model for data centers with pattern-consistent calibration (submitted 8 Feb 2026).

  • Main announcement: The paper proposes a physics-based parameterized load model for large electronic loads (LELs) combined with pattern-consistent calibration using temporal contrastive learning (TCL); the model is calibrated locally at facilities (privacy-preserving: only calibrated parameters are shared with utilities) and validated on operational datasets MIT Supercloud, ASU Sol, Blue Waters, and ASHRAE and integrated into the ANDES platform for grid tests.
  • Background and evaluation details: The calibrated model was integrated into ANDES and evaluated on transmission test systems IEEE 39-bus, NPCC 140-bus, and WECC 179-bus; authors report that interactions among LELs alter post-disturbance recovery, producing compound disconnection-reconnection dynamics and delayed stabilization. The paper is available on arXiv (DOI via DataCite pending).

  • Main summary: The article provides a market overview noting the United States leads with 4,165 data centers (about 3,000 more being built/planned) and estimates the sector could reach US$22.7 billion by 2030 driven by generative AI, cloud services, 5G, and IoT. It cites major investment figures including Google >€5.5 billion (US$6.37 billion) in Germany and a €1 billion project involving Nvidia and Deutsche Telekom.
  • Background & details: The piece aggregates third-party reports and data (Statista, Axios, McKinsey, JLL, Datum, Baxtel, Global Data Center Hub) and provides regional details: McKinsey’s US$6.7 trillion capex by 2030 (US$5.2 trillion for AI-optimized facilities, US$1.5 trillion for typical IT), Latin America growth from ~US$5bn (2023) to >US$10bn by 2029, and capacity/footprint statistics for countries and hyperscale operators. It is an informational market overview, not a primary announcement of a single new project with implementation timelines.

  Rethinking Water in the AI Data Center Era

  Gradiant announced it secured two contracts to design and deploy sustainable water solutions for new data center sites in the United States and the Indo-Pacific (May 2025), positioning large AI campuses as mission-critical industrial water systems rather than secondary cooling loads.

  • Main announcement: Gradiant (May 2025) secured two contracts to design and deploy industrial-scale water solutions in the United States and the Indo-Pacific, emphasizing zero liquid discharge (ZLD) and systems that can recover/reuse up to 99% of process water onsite; the company also promotes its SmartOps AI platform for real-time water/wastewater operations and reliability.
  • Background & related actions: Other verifiable initiatives include Meta + ION Water (Jan 15, 2026) launching a watershed-scale program in the Brazos River Watershed to conserve ~26 million gallons over five years (metered, in-watershed measurement); Xylem + Amazon (Sept 2025) announced municipal-scale leakage-reduction projects in Mexico City and Monterrey estimating >1.3 billion liters/year saved (including ~800 million liters in Mexico City); Koomey Analytics’ Dec 2025 snapshot found Amazon had 24 confirmed sites using reclaimed municipal wastewater for cooling.

  Microsoft unveils Maia 200 AI chip to power inference

  Microsoft has introduced Maia 200, a custom AI accelerator for inference workloads and has begun deploying it in its cloud data centres.

  • Main announcement: Microsoft introduced the Maia 200 accelerator built on a 3-nanometre process from TSMC with more than 140 billion transistors, 216 GB HBM3e (≈7 TB/s throughput), 272 MB on-chip SRAM, a 750-watt TDP, and performance claims of >10 petaFLOPS FP4 and >5 petaFLOPS FP8; Microsoft says it is already operational in U.S. Central (near Des Moines, Iowa) with rollouts planned to U.S. West 3 (Phoenix) and is deployed to accelerate services including Microsoft Foundry, Microsoft 365 Copilot, and OpenAI’s GPT-5.2.
  • Background and details: Microsoft pairs Maia 200 with a two-tier scale-up Ethernet network supporting clusters of up to 6,144 accelerators with ~2.8 TB/s bidirectional bandwidth per unit for scale-up communication; the company is releasing an SDK preview with PyTorch integration, Triton support, optimized kernels, and a low-level programming language, and claims ~30% better performance per dollar for inference vs the latest fleet hardware while positioning FP4/FP8 performance relative to Amazon Trainium v3 and Google TPU v7.

  EPA moves toward changing particulate matter standard as manufacturers urge action

  The U.S. Environmental Protection Agency is moving to revisit and ask the court to vacate the Biden-era annual PM2.5 standard of nine micrograms per cubic meter.

  • Main action: The EPA filed a motion in the U.S. Court of Appeals for the District of Columbia Circuit asking the court to vacate the March 2024 PM2.5 annual standard (lowered from 12 µg/m3 to 9 µg/m3). The agency said the Biden EPA took a “regulatory shortcut” and failed to adequately consider compliance costs; EPA urged vacatur before the initial nonattainment determinations due on Feb. 7 and states’ implementation plans due in April.
  • Background and details: Industry groups including NAM and 15 trade associations (e.g., SMA, Aluminum Association, American Cement Association) have pressed the Trump administration to revert the standard; EPA previously estimated the 2024 rule could prevent 4,500 premature deaths and 290,000 lost workdays, with monetized benefits of $22 billion to $46 billion and $590 million in estimated costs by 2032. A 2025 ACA report estimated 1 million metric tons of cement needed for AI data centers by 2028 and projects U.S. data centers rising from 5,426 to 6,000 by 2027.
