AI Needs Power. Scaling It Without Raising Ratepayer Costs Requires a New Power Strategy.
Joel Yu (via LinkedIn) recommends that developers pair grid electricity with flexible onsite generation to accelerate AI data center deployment while protecting ratepayers.
- Main announcement/action: Joel Yu argues that pairing grid electricity with flexible onsite generation enables developers to energize AI data centers earlier (using onsite generation as prime power) while utilities complete interconnection upgrades, helping protect ratepayers; the article notes typical hyperscale data center loads of hundreds of megawatts and describes a phased transition to full grid service when available.
- Details & context: The piece cites ERock constructing a Northern California power system for a Microsoft facility that pairs grid supply with ultra-low-emission natural gas generation offset by renewable natural gas and CARB DG compliant, describes the role of such assets in CAISO resource adequacy, and references the White House Ratepayer Protection Pledge, federal regulators drafting new interconnection rules, and stretched interconnection timelines that are creating deployment bottlenecks.

Energy group asks Congress to investigate potentially foreign-backed campaigns against AI data centers
Power the Future has asked Congress to open formal investigations into funding it alleges is incentivizing nonprofits and local groups to oppose data center and AI projects.
- Requested action: Power the Future sent a letter to Rep. James Comer (R-Ky.) and Sen. Rand Paul (R-Ky.) asking committees to open formal investigations into what it describes as a “coordinated, billionaire-funded, and potentially foreign-backed political campaign” to block construction of data center and AI infrastructure. The group reports 188 local opposition groups across 24 states and cites grant reporting that New Venture Fund, the Sierra Club Foundation and the Sixteen Thirty Fund collectively received over $13 million from pro-environmental donors.
- Background/details: The letter raises concerns that U.S. nonprofit donor disclosure laws can shield donors from public disclosure; it names environmental organizations (Sierra Club, Food and Water Watch, Earthjustice, Goods Jobs First, Piedmont Environmental Council, Southern Environmental Law Center, MediaJustice, Athena Coalition) as recipients of funding they say has been spent opposing data center expansions. Power the Future founder Daniel Turner acknowledges some legitimate local concerns but urges scrutiny of the scale and source of funding. The letter quotes Interior Secretary Doug Burgum calling opposition a “surrender” to China. No formal investigation timeline is provided in the article.

Scenes from the great data center revolt
Andy Patrizio reports growing community and political pushback against multiple proposed data center projects across the United States.
- Widespread local opposition and legal/political actions: Multiple communities have moved from passive concern to active resistance, including a recall of four Festus, Missouri city council members after approval of a $6 billion, 360-acre data center proposal; a citizens’ lawsuit in Hermantown, Minnesota to block a $1.5 billion Google “Project Loon” site; and a coalition in Pennsylvania seeking a three-year moratorium plus legislation (HB 2150, HB 1834, HB 2151) requiring reporting on energy/water use, banning cost-shifting to residents, and a model zoning ordinance.
- Project specifics and mitigations for two large developments: In Box Elder County, Utah, a Kevin O’Leary–backed hyperscale campus on 40,000 acres plans an initial ~3 GW power need and up to 9 GW at full buildout with on-site power via the Ruby Pipeline (MIDA says “100% of the power will be generated off the Ruby Pipeline”); Wyoming’s Project Jade expanded from 1.8 GW to 2.7 GW (designer says theoretically up to 10 GW) and proposes closed-loop water cooling with initial fill equivalent to ~20 households and ongoing use equivalent to <3 households per year.
