Mobilizing for Techno-Economic War, Part 7: Transforming Regulatory Policy
ITIF has published a policy report arguing for a major transformation of U.S. regulatory policy to support national techno-economic competition with China.
- The report says Congress should centralize national issues such as AI regulation, preempt many state privacy/AI laws, and reduce federal barriers for nationally important projects such as industrial parks, infrastructure, and data centers.
- It also argues for NEPA repeal, Section 404 repeal, size-neutral rules, antitrust reform, and a new Commerce Department process to designate up to 100 projects per year for streamlined approval; it also proposes federally designated industrial readiness zones of 50–100 sites of at least 3,000 acres each.
- Monetary values mentioned include $98 billion–$112 billion annually in potential out-of-state privacy compliance costs, $1 trillion+ over 10 years, $650 million in a Facebook BIPA-related settlement cited in the report, and $100 billion a year for carbon removal referenced in a supporting example.

Coal Got an Order. Nuclear Got a Meeting
Henri Francois argues that U.S. energy planning is being distorted by exaggerated data center load forecasts, while coal plants are being kept online through emergency orders and nuclear projects face long approval delays.
- The commentary says the Department of Energy has issued more than 40 Section 202(c) emergency orders since May 2025, helping keep at least 4.4 GW of coal-fired generation from retirement; it also cites ERCOT’s 438 GW large-load queue, nearly 90% from data centers.
- It highlights Centralia in Washington state as a 730 MW coal plant on its third consecutive 90-day order, and says TransAlta has asked FERC for $19.9 million to cover the first order; the piece also notes TVA’s 300 MW Clinch River SMR application and the NRC review timeline.
