PJM proposals shift new-build funding toward data centres EPA air-permit enforcement risk for portable/temporary turbines Onsite generation scrutiny at xAI Memphis (turbines, NOx impacts) Nuclear PPAs/SMR offtake re-emerge for AI load growth Local permitting and community pushback in Michigan for large campuses

Top news (3)

  1. PJM market redesign aimed at making hyperscale load pay for new generation: The White House plus 13 governors urged PJM to run an auction offering 15-year contracts so data centre operators fund new power plants, and to extend a wholesale payment cap through mid-2028. PJM also floated emergency curtailment mechanisms for large users and faster interconnection proposals (US urges PJM to make data centers fund new power plants).

  2. EPA tightens air-permitting expectations for “portable/temporary” gas turbines: The EPA clarified that methane gas turbines— even if temporary/portable—require air permits, raising regulatory risk for data centre buildouts using trailer-mounted generation. This is directly linked to scrutiny at xAI’s Memphis site (EPA rules xAI Memphis data centre used illegal power).

  3. Nuclear resurfaces as a credible supply option for AI-driven demand growth: At an IAEA convening, tech and nuclear stakeholders discussed scaling nuclear amid projected electricity demand growth of >10,000 TWh by 2035. Recent examples cited include Microsoft’s 20-year PPA to restart Three Mile Island Unit One and Google’s agreement to buy energy from multiple SMRs targeting operation by 2030 (AI drives renewed push for expanded nuclear power capacity).


Key deals & projects (by region)

United States

  • xAI (Memphis, TN) – “Colossus” data centre build and onsite generation

    • EPA ruled xAI operated up to 35 unpermitted methane gas turbines at its Memphis Colossus data centre; EPA clarified that portable/temporary turbines require air permits (EPA rules xAI Memphis data centre used illegal power).
    • Site details disclosed in the story:
      • Colossus 1 load:150 MW
      • Delivery speed: built in 122 days (2024)
      • Expansion: references to Colossus 2 and MACROHARDRR, which “may need up to 2 GW
  • Michigan – community and regulatory pushback around large campuses

Global (nuclear contracting examples referenced)

India

  • System demand and buildout context relevant to data centre power planning:

Power, grid & interconnection highlights

PJM (US): capacity procurement, curtailment risk, and interconnection acceleration

Michigan (US): utility service conditions for hyperscale load

India: transmission capex and grid expansion


Policy & regulation

United States: air permitting for onsite generation at data centres

Austria (EU): critical infrastructure resilience framework

United States (local): permitting and community constraints


2-line wrap

Policy and market design are tightening around hyperscale load—both via who pays for new generation (PJM) and how onsite turbines are permitted (EPA).
At the same time, the supply conversation is widening, with nuclear (large and SMR) increasingly positioned as an option for AI-driven demand growth.
