Presidential Determination 2026-10 is an executive action signed by President Trump on April 20, 2026 that invokes Section 303 of the Defense Production Act (DPA) to classify electricity-grid hardware as essential to national defense. The covered categories are transformers (including grid-scale and step-down), transmission components, substations, and grid power electronics. The action authorizes federal financial-instrument support for domestic production of these categories and is framed as a response to AI-driven grid demand. As of the most recent review, the body text rests on a single secondary source; the primary text of the Determination has not been retrieved.
Scope and covered categories
The Determination designates four categories of grid hardware as essential to national defense:
- Transformers, including grid-scale and step-down units
- Transmission components
- Substations
- Grid power electronics
Once made, the "essential to national defense" determination is the gating predicate that allows agencies to deploy DPA financial instruments. It authorizes federal financial-instrument support — loans, loan guarantees, purchase commitments, and direct procurement — for domestic production of the covered categories (Source: citriniresearch.com).
Statutory mechanism
Section 303 of the DPA authorizes the President to make loans and loan guarantees to private firms, purchase or commit to purchase output from designated industries, provide subsidies for the installation of equipment, and take other specified financial actions to expand productive capacity for items essential to national defense. Once the determination is made, agencies that commonly implement Section 303 — the Department of Energy, the Department of Defense, and the Department of Commerce — can deploy the financial instruments without case-by-case Congressional authorization (Source: citriniresearch.com).
AI-grid context
The action is framed as a response to AI-driven grid demand, specifically the data-center buildout supporting frontier AI training and inference. According to Citrini Research, it is the first DPA Section 303 invocation in the AI policy era to target grid hardware rather than chips, weapons, or critical minerals, treating the electricity-distribution layer as an AI-policy bottleneck. Citrini links the action to industry concerns that grid interconnection queues, transformer lead times of roughly two to four years for grid-scale units, and substation buildout now constrain the pace of frontier-AI capacity expansion alongside fab capacity and H100 supply (Source: citriniresearch.com). AI-driven energy demand has already pushed the U.S. utility system into capacity-shortfall warnings.
The Determination joins other AI-grid-adjacent federal actions. America's AI Action Plan (2025) identifies grid capacity as a competitiveness constraint. Executive Order 14110 — Safe, Secure, and Trustworthy AI and Executive Order 14179 — Removing Barriers to American Leadership in Artificial Intelligence addressed AI itself, whereas this Determination addresses an infrastructure dependency. Recent Federal Energy Regulatory Commission orders have addressed co-located data-center and generation projects.
The same week, Related Digital and Blackstone closed $16B in financing for an Oracle Michigan data-center campus to power OpenAI, the type of project the Determination is designed to accelerate (Source: bloomberg.com).
