    Source: California ISO · Sep 10, 2026

    According to CAISO, the ISO will host a hybrid stakeholder meeting on Oct. 1, 2026 for the Large Loads Initiative, post a draft final proposal on Sep. 24, 2026, and open comments due by Oct. 15, 2026. CAISO also says stakeholders will review the proposal before it goes to the Board of Governors and before the ISO files tariff language with FERC, indicating an active regulatory process for large loads in California.

    Large Loads Initiative: Additional discussion of operational and technical requirements, call on 8/24/26

    Source: California ISO · Aug 17, 2026

    California ISO said it scheduled an additional stakeholder meeting for the Large Loads Initiative “to provide additional time, if needed, to discuss the operational and technical requirements” in the Large Loads Straw Proposal and Large Loads Technical Requirements Straw Proposal, with topics including “Operational requirements” and “Technical requirements” (California ISO, Aug. 17, 2026). The notice also says the Aug. 24 meeting was contingent and ultimately unnecessary because “We were able to cover all of the material and will no longer need the meeting on 8/24.”

Recent California data center news

  • Google Has Deal With NextEra to Restart Duane Arnold Nuclear Plant

    NextEra Energy announced Google has signed a 25-year power purchase agreement that enables NextEra to restart the 615-MW Duane Arnold Energy Center and NextEra has agreed to acquire CIPCO and Corn Belt’s combined 30% interest to become the plant’s sole owner.

    • Main announcement: NextEra and Google signed a 25-year PPA for power from the 615-MW Duane Arnold Energy Center; NextEra said the contract “enables the investment to restart the plant and covers costs for the production of energy from Duane Arnold.” NextEra expects the plant could be operational as soon as early 2029, and CIPCO will buy output under the same contract terms as Google.
    • Background and details: NextEra agreed to acquire Central Iowa Power Cooperative and Corn Belt Power Cooperative’s combined 30% interest to assume full ownership; Google noted a recent $7-billion investment in Iowa and said the restart supports its cloud and AI infrastructure in the state. NextEra stated it is coordinating with the Nuclear Regulatory Commission and local authorities and has nearly 3 GW of projects executed with Google nationwide.
  • PJM’s Speed to Power Problem and How to Fix It

    RMI authors call on PJM to prioritize speeding interconnection so queued generators can compete and reduce soaring capacity costs.

    • Main action: RMI urges PJM to speed interconnection to allow queued resources to enter the market sooner; key facts: average interconnection timeline >8 years (2025) vs. 1-year expert target, capacity price spike from $29/MW-day to $330/MW-day, and total capacity bill increase from $2.2B to $16.1B (latest auction). These delays forced customers to pay an additional $13.9B to existing generators.
    • Background and details: PJM completed TC1 in 544 days; over 100 GW applied to TC1 and ~40 GW were studied in the first phase (article notes XX received agreements); FERC granted a 540-day independent entity variation; TC1 network upgrade costs average ~$309k/MW (far above NREL and DOE benchmarks). RMI recommends software deployment, ERIS reform, advanced transmission technologies (ATTs), and proactive transmission planning with concrete references to Pearl Street, Nira Energy, GridAstra, Quanta and related studies.
  • AI’s Growing Appetite: What the Grid Needs to Keep Up

    Bryce Yonker / Grid Forward highlights the need for grid upgrades and market reforms to meet rapidly rising electricity demand from AI data centers.

    • Main announcement/action:Grid Forward (Bryce Yonker) calls for major grid upgrades, market reforms, and expanded cybersecurity programs to support AI data centers that now commonly require 100–200 MW, with some designs targeting 500 MW to several GW; he cites projected U.S. data-center electricity growth of 3.7%–15% annually to 2030 and recommends investments in Advanced transmission conductors, Grid-enhancing technologies (dynamic line rating), modern switchgear, AI-driven grid applications, on-site generation (hybrid renewables, geothermal, natural gas, SMRs), and load flexibility.
    • Background and implementation details: The article reviews existing and emerging measures including FERC Order 2023 (streamlining transmission planning and interconnection via consolidated planning and expedited studies with RTOs/ISOs such as SPP, MISO, CAISO); describes a recent Indiana settlement requiring new large loads >70 MW to sign long-term contracts (up to 12 years) with ramp-in periods, minimum charges, and upfront collateral; and lists equipment lead times (distribution transformers 30–50 weeks, large power transformers up to 150 weeks, switchgear ~1 year+) as constraints that require domestic supply-chain incentives and standardized protocols.
  • Liquid cooling lessons from HPC to AI factories: How to enable next-gen AI data centers

    Motivair applies its exascale liquid-cooling expertise to enable AI factories at scale.

    • Main announcement/action: Motivair is leveraging proven HPC/exascale liquid-cooling systems (used on Frontier, Aurora, El Capitan) to supply modular, repeatable cooling infrastructure for large-scale AI factories, including CDUs, ChilledDoors®, cold plates, and in-rack manifolds, scaling from 100 kW racks to multi-megawatt campuses.
    • Background and technical details: Highlights key thermal variables — pressure drop, ΔT, and flow rate — with concrete figures: rack densities moved from 20–50 kW (air-cooled) to 300–400 kW (liquid-cooled); recommended flow is ~1–1.5 liters per minute per kW at under 3 PSI; Motivair’s engineered loops aim to stabilize ΔT and maintain GPU clock speeds across thousands of racks.
  • Advocating for Public Power Companies: LPPC Focuses on Load Growth, FEMA Reform, and Tax-Exempt Bonds

    The Large Public Power Council (LPPC) is advocating federal policy changes to address rapid electricity load growth driven by data centers, AI, and electrification, and is pushing for FEMA process reforms and updates to Treasury rules on tax-exempt bonds.

    • Main announcement/action: LPPC (29 member public power systems serving 30.5 million consumers across 23 states and territories) is urging Congress and federal agencies to re-examine queue processes, finance mechanisms for large loads, and FEMA procedures to accelerate infrastructure delivery; LPPC highlights that about half of its members are experiencing rapid load growth that could double over the next 10 years, with individual new customers now seeking up to 1 GW of capacity (“enough to power probably 600,000 homes”).
    • Background and specifics: LPPC president Tom Falcone identified specific reforms: support for the FEMA Act of 2025 (House proposal by Chairman Graves and Ranking Member Larsen) to reduce disaster grant delays, and revisions to U.S. Treasury regulations on tax-exempt bonds related to “private use” that limit long-dated contracts with customers; LPPC notes permitting, public processes, construction, and supply-chain timelines constrain how fast utilities can build.
  • NVIDIA, Partners Drive Next-Gen Efficient Gigawatt AI Factories in Buildup for Vera Rubin

    NVIDIA unveiled MGX and Kyber designs at the OCP Global Summit, presenting open-standard rack and compute-tray architectures and an ecosystem for 800 VDC gigawatt-scale AI data centers.

    • Main announcement/action: NVIDIA announced the Vera Rubin NVL144 MGX open-architecture rack servers and previewed the NVIDIA Kyber rack generation; supporting details include: 50+ MGX partners, Kyber to connect 576 Rubin Ultra GPUs by 2027, and Vera Rubin NVL144 features 100% liquid cooling, a midplane PCB replacing cable connections, 45°C liquid cooling, and a liquid-cooled busbar with 20x more energy storage.
    • Background/other details: multiple ecosystem partners and implementations were described, including Foxconn’s 40-megawatt Kaohsiung-1 data center (Taiwan) built for 800 VDC, Vertiv’s 800 VDC MGX reference architecture, HPE and others adding product support for NVIDIA Kyber and Spectrum-XGS; the summit (OCP Global Summit) took place Oct. 13-16 at San Jose Convention Center, agenda topics included:
      • Oct. 13-16, San Jose Convention Center — sessions and demos covering MGX rack servers, 800 VDC power delivery, liquid cooling, and Kyber rack architecture
      • Ecosystem showcases from silicon, power system and cooling vendors, and cloud/service providers demonstrating implementations and reference architectures
