Recent California data center news

  • EPA Launches Resource Page to Support Development and Permitting for Data Center and AI Construction Projects

    The Environmental Protection Agency (EPA) has launched a centralized resource hub and signaled upcoming Clean Air Act rule changes to support data center and AI facility development.

    • EPA action: The EPA’s Office of Air and Radiation unveiled the Clean Air Act Resources for Data Centers webpage consolidating air permitting, regulatory, and modeling materials tailored to data centers and artificial intelligence (AI) facilities; stakeholders are advised to monitor EPA regulatory dockets and the resource page for updates.
    • Rulemaking and timeline: The agency indicated important revisions to the New Source Review (NSR) definition (how the agency will define commencement of construction) — the NSR rulemaking is expected to be proposed in early 2026 and finalized by fall 2026; the authors recommend that owners, developers, and contractors prepare technical and legal analyses and plan to participate in comment periods.
  • Data Center Sustainability Trends: 10 Stories That Defined the Year

    The data center industry announced sustainability has become an immediate operational constraint in 2025.

    • Main development: 2025 saw AI-driven growth push sustainability into operational decision‑making: water usage and Water Usage Effectiveness (WUE) became central for cooling and site selection; power sourcing (renewables and consideration of nuclear SMRs) moved to the forefront. Key concrete items: $5B boost for a net‑zero AI data center project in Saudi Arabia, an $800B projected APAC data center buildout raising energy and land-use questions, and a detailed sustainable design example from Arcadis and Terra Ventures in San Jose, California.
    • Background and detail: Policymakers tightened regulations on emissions reporting, water rights, and land use in 2025, while public concerns over noise, water use, and grid demand influenced permitting. Practical responses included design model updates, regional planning strategies, transparency on sustainability metrics, and exploration of SMRs as long‑term baseload options.
  • Agreement Secures Renewable Energy, Recycled Water for Pittsburg Data Center

    The Center for Biological Diversity reached an agreement with the City of Pittsburg and the project’s developers to require renewable energy, recycled water, and wildlife protections for a multi-phase data center project filed in court on December 16, 2025.

    • Main agreement and conditions: The settlement requires a $750,000 developer payment into a fund for climate resiliency projects benefiting disadvantaged Pittsburg communities; a commitment to 100% renewable energy for the data center; rooftop solar, electrical hook ups in parking spaces, EV infrastructure, recycled water for data center cooling and landscaping; zero-emission construction equipment; and insulated walls/low-noise equipment to reduce sound. The Center agreed to dismiss its legal challenge and not oppose the first phase; the agreement also requires separate environmental review for future phases.
    • Background and implementation details: The dispute followed the city’s 2024 project approval for three phases of industrial development; the agreement explicitly includes biological surveys and monitoring for Western pond turtles and Western burrowing owls, and mandates measures to reduce greenhouse gas pollution, water use, and wildlife harms. No specific implementation timeline beyond the requirement for separate review of future phases is provided in the article.
  • Environmentalists and Affordability Duke It Out in New York

    New York Gov. Kathy Hochul has shifted to an affordability-focused energy agenda, approving the NESE natural gas pipeline, reversing opposition to new nuclear, streamlining permitting, and establishing a $500 million Empire AI Consortium to support power-hungry AI capacity in the state.

    • Main actions and timeline: Hochul approved the NESE natural gas pipeline (reported Nov 2025) and directed the New York Power Authority to pursue a new zero-emission advanced nuclear plant; her administration has streamlined permitting for electric power and transmission infrastructure and announced the Empire AI Consortium — a $500 million public-private partnership to advance AI/data-center capacity in New York. The NESE approval was explicitly framed by Hochul as a return to an “all-of-the-above” policy and is cited by supporters (Breakthrough Institute letter) as likely to lower regional costs and carbon by displacing heating oil.
    • Background and related developments: The House passed the SPEED Act (sponsored by Rep. Bruce Westerman) to limit NEPA reviews and expedite permitting; Diablo Canyon received a state permit to continue operating for another 20 years but still needs a final NRC license extension and state legislative approval to operate after 2030. Environmental groups (e.g., League of Conservation Voters, Food & Water Watch) criticized Hochul’s moves in reports and public statements (December 2025 LCV report; quotes from Bill McKibben and Alex Beauchamp).
  • Climate Change Solutions - December 16, 2025

    The Environmental and Energy Study Institute (EESI) issues a Climate Change Solutions newsletter summarizing recent climate, energy, and environmental policy developments, briefings, and media coverage in the United States.

    • Newsletter content highlights articles on FEMA reform (FEMA Act, H.R.4669), ghost fishing gear in Hawaiʻi, and global green building standards (LEED, BREEAM), plus an EESI briefing on how the One Big Beautiful Bill Act (P.L. 119-21) changed 12 clean energy and efficiency tax incentives and how companies and consumers are adjusting.
    • Capitol Hill updates cover House passage or advancement of the Electric Supply Chain Act (H.R.3638), ePermit Act (H.R.4503), ESTUARIES Act (H.R.3962 / S.2063), and multiple PFAS bills (H.R.6668 / S.3457, H.R.6626 / S.3460, H.R.6667, S.3445, S.3446), as well as links to EESI legislative trackers, grid and industrial decarbonization briefings, and external media citations of EESI work on data centers, water use, and EERE investments.
  • Trump Media Group, Fusion Company TAE Merging in $6-Billion Deal

    The Trump Media & Technology Group (TMTG) announced an all-stock merger with TAE Technologies in a $6-billion deal to create one of the first publicly traded fusion companies.

    • Main transaction details: The deal is an all-stock merger valued at $6 billion, with shareholders of Trump Media and TAE each to own about 50% of the combined company; TMTG will provide up to $200 million in cash at signing and an additional $100 million upon initial filing of Form S-4. Devin Nunes (TMTG) and Michl Binderbauer (TAE) will serve as co-CEOs, and Michael B. Schwab is expected to be named chairman of the combined company.

    • Background, investors, and project timelines: TAE expects to begin work next year on a 50 MW fusion power plant with later scaling to 500 MW, and is targeting “first power in 2031”; existing investors include Chevron Technology Ventures, Charles Schwab, Goldman Sachs, Sumitomo, and Alphabet; TAE also announced a joint venture with the UK Atomic Energy Authority and has reported recent technical milestones (e.g., plasma temperatures exceeding 75 million C).

  • Calls for US Data Center Freeze Grow as Local Enthusiasm Melts

    Senator Bernie Sanders has called for a national moratorium on new data center construction, urging Congress to slow AI expansion and involve more people in decisions about AI’s future.

    • Main action and scope:Sen. Bernie Sanders publicly advocated a national moratorium on data center construction; more than 200 environmental organizations (via a letter) also called for a moratorium citing impacts on water resources, electricity consumption, and greenhouse gas emissions; Data Center Watch reports $64 billion in data center plans have been blocked or delayed by local activism in the last two years.
    • Background and additional details: Federal debate is split—Senators Elizabeth Warren, Chris Van Hollen, and Richard Blumenthal are investigating links between data center power usage and rising consumer bills and have sent letters to major hyperscalers (Microsoft, Google, Amazon, Meta, CoreWeave, Digital Realty, Equinix); the Trump administration and U.S. Energy Secretary Chris Wright have pushed for accelerated permitting and less state regulation; a Carnegie Mellon University study projects data center and crypto growth could raise average U.S. electricity costs ~8% by 2030 (with regional spikes, e.g., >25% in Virginia).
  • How the 2026 Washington Legislature Can Right-Size the Power Grid  

    Washington State lawmakers are being urged to overhaul transmission planning and permitting to expand grid capacity and connect more clean energy by 2026.

    • Main reforms proposed include creating a state transmission authority with revenue bonding power, broadening EFSEC expedited processing to avoid trial-like adjudicative hearings, clarifying or mandating that transmission lines be allowed in most/all local zones, and targeted SEPA exemptions or substitutions where impacts are minimal or already covered by EFSEC standards, all while preserving Tribal consultation and privacy.
    • Context and details: Article cites New Mexico, Colorado, and California public or quasi-public transmission models, highlights decade-long stagnation in Washington grid build-out, documents multi-year local conditional use permit delays (e.g., Energize Eastside) and their cost pass-through to PSE customers, and references recent historic flooding in Washington as evidence of escalating climate risks that make faster grid expansion urgent.
  • Advanced Nuclear Developers Raise New Capital as 2025 Investment Hits Record Levels and Demonstrations Near

    Radiant, Last Energy, and ARC Clean Technology announced the closing of major private funding rounds in mid-December 2025 to accelerate demonstration, factory-built manufacturing, and regulatory pathways for microreactors and SMRs in North America and the UK.

    • Fundraises & near-term uses: Radiant raised more than $300 million (Series D) on Dec. 17, 2025 to scale commercialization, break ground on the R-50 factory in Oak Ridge, Tennessee (construction slated early 2026) and test its Kaleidos microreactor at Idaho National Laboratory (DOME) in 2026 with initial deployments targeted in 2028; Last Energy closed an oversubscribed Series C of more than $100 million (Dec. 16, 2025) to fund its PWR-5 pilot at Texas A&M–RELLIS (DOE Reactor Pilot Program, target criticality 2026) and parallel UK licensing for PWR-20 commercial units (site-licensing target Dec. 2027); ARC closed a Series B (Dec. 16, 2025) to advance the 100-MWe ARC-100 deployment, DOE programs, Canadian project development, and KHNP collaboration.

  • Reexamining Paradigms of End-to-End Data Movement

    The paper “Reexamining Paradigms of End-to-End Data Movement” analyzes bottlenecks in high-speed wide-area data transfer beyond raw network bandwidth using experimental testbeds and production measurements.

    • Main finding: High-performance data transfer over 1–100 Gbps+ WAN links is often limited by non-core factors such as network latency, TCP congestion control, CPU performance, and virtualization, as demonstrated using a latency-emulation-capable testbed and an operational 100 Gbps link between Switzerland and California, U.S.
    • Context and methodology: The authors examine six common paradigms of data movement across edge-to-core environments, show that principal bottlenecks reside outside the network core, and argue that holistic hardware–software co-design is required to align benchmark performance with complex production workflows; the study is published on arXiv (19 pages, 13 figures, DOI: 10.48550/arXiv.2512.15028) under a CC BY 4.0 license.
