What the order does
President Trump just signed an executive order that will shut the door on any foreign‑made bulk‑power equipment bought for U.S. transmission lines of 69 kV or higher after August 26 2026.
The ban applies to acquisition, import, transfer or installation of such gear when the transaction involves a designated foreign entity. It does not name any country, but the language mirrors a 2020 order that specifically targeted entities linked to China before being rescinded.
Why it matters
U.S. bulk‑power transmission is the backbone of the nation’s electricity supply. By restricting foreign‑sourced components at the transmission level, the order shifts the focus upstream – from defending against network intrusions to hardening the hardware that sits in substations.
For any utility that relies on imported transformers, inverters or control‑system modules, the deadline is clear: either source domestically, qualify for an exemption, or be prepared to replace the equipment after the cut‑off.
Technical scope
The order lists a wide swath of technologies:
- Transformers
- Inverters
- Energy‑storage systems
- Industrial control systems – remote terminal units (RTUs), programmable logic controllers (PLCs), safety systems
- Associated firmware and software
- Remote‑access capabilities
For gear already installed before the order takes effect, the Energy Department can impose security controls – from monitoring and isolation to outright replacement.
Who’s affected
U.S. transmission operators, the manufacturers that supply them, and the foreign vendors that would have been the source of the equipment all feel the impact. The order also opens a pathway for the DOE to publish a pre‑qualified list of vendors whose products are exempt, creating a de‑facto whitelist.
What you can do now
Even if your organization isn’t in the United States, the move signals a tightening of supply‑chain scrutiny that could ripple through global markets. Here are practical steps:
- Audit your inventory of bulk‑power hardware and identify any items that fall under the 69 kV threshold.
- Map the origin of each component – note any foreign manufacturers that could become “designated entities”.
- Engage with vendors early to confirm whether they plan to seek exemption or shift production to a U.S. base.
- Develop a migration plan that includes alternate suppliers, stock‑piling of critical spares, or retrofitting existing gear with approved security controls.
- Monitor DOE releases for the forthcoming pre‑qualified equipment list; align your procurement strategy accordingly.
Staying ahead of the compliance curve now can spare you costly replacements and downtime later.
