The Emergency Order Has a Line at 69,000 Volts

Here's a question worth sitting with if you're sourcing equipment for a project right now: how do you comply with a rule that doesn't exist yet, on a deadline that already passed?

That's the position every solar, storage and data-center developer buying grid-connected hardware has been in since August 26, when President Trump signed Executive Order 14420, declaring a national emergency over the security of the US bulk-power system. The order took effect the moment it was signed. It reaches back to cover any equipment transaction "initiated after" that date. And the agency responsible for saying exactly which equipment, which countries, and which companies fall inside it — the Department of Energy — has until December 24 to write those rules. There is no grace period. There's just a four-month gap between the deadline and the definitions.

What the order actually restricts

Invoking the International Emergency Economic Powers Act and the National Emergencies Act, EO 14420 targets "bulk-power system electric equipment" connected to transmission lines rated at 69,000 volts or more — the high-voltage backbone, not the wires running to a rooftop or a substation transformer feeding a subdivision. Inside that line, the order names reactors, capacitors, substation transformers, utility-scale and other grid-connected inverters, battery energy storage systems, uninterruptible power supply systems, and the industrial control systems — remote terminal units, programmable logic controllers, intelligent electronic devices — that run them, along with their software, firmware and remote-access capabilities.

The order doesn't name a country. It defines a "Covered Foreign Entity" procedurally: an entity under a US arms embargo or sanctions regime, or one the Secretary of Energy determines is "engaged in conduct that is detrimental to" US national security. Every legal alert reading it names the same practical target anyway — China, whose manufacturers dominate both inverter and battery-system supply. DOE has 120 days from signing, until December 24, to publish the rules that turn that procedural definition into an actual list.

This didn't arrive out of nowhere. On July 28 the FCC had already added foreign-produced power inverters with remote-communication capability to its Covered List, barring them from new equipment authorization on cybersecurity grounds. Two federal actions in a month, aimed at the same hardware, is a trend line — not a one-time announcement.

The equipment this actually touches

China's dominance of this hardware is not a marginal fact. Chinese system integrators held 76% of the global BESS market in 2025 — a global figure, worth stating as one, but the US market draws from the same supply base. Sungrow, the largest Chinese inverter maker with US exposure, has told investors the American market accounts for roughly 15% to 20% of its revenue — real money, tied to hardware that may now need a DOE risk determination before the next order ships.

The loophole is already staffed

What's telling is how fast the targeted companies found the order's own seam. The rule only reaches equipment on lines rated 69 kV or above. Within days of the signing, Jinpan Technology told the trade press its products are "mainly used in customer-side distribution systems" and therefore fall "largely outside the bulk-power rules." MingYang Electric said its US-rated products sit at "34.5 kV or below" — comfortably under the line. Sungrow, for its part, isn't rebuilding around the US market at all: it's shifting resources toward other regions rather than opening US manufacturing, calling the competitive conditions unfavorable.

None of this is evasion in the legal sense — the order was written with a voltage threshold, and a manufacturer sizing its product line to sit under that threshold is reading the text correctly. But it means the emergency order's practical bite, for now, depends less on where equipment is made than on where in the interconnection it sits. A battery system behind the meter reads differently than the same battery system feeding a 138 kV line, and everyone selling into this market now knows it.

What developers are being told to do now

Legal guidance circulating to the industry since the signing — including an alert from Davis Wright Tremaine — converges on the same short list, because the order left no other option: map the full equipment supply chain, including software and remote-access vendors, not just hardware; identify every transaction initiated after August 26; review existing contracts for change-in-law provisions and substitution rights; and document sourcing decisions now, because the diligence record you keep today is the one DOE will eventually judge against rules it hasn't written.

What it means

If you're procuring inverters or BESS for a project inside the 69 kV threshold: the order is not yet a ban on any specific product — it's a compliance obligation running four months ahead of the list that defines it. Treat every post-August-26 order as provisional until DOE publishes.

If your project sits below 69 kV, or the equipment is customer-side: you are very likely outside this order's current scope, and the manufacturers you buy from already know it. That won't stop a future DOE rule from moving the line — nothing in EO 14420 fixes 69 kV as permanent.

If you're evaluating suppliers: country of manufacture is now a due-diligence question with a federal answer pending, not a preference. The paper trail matters more than it did on August 25.

What this analysis does not tell you

DOE's implementing rules — due December 24 — do not exist yet, and nothing here predicts which specific companies or equipment categories they will name. Executive Order 14420 does not by itself prohibit any transaction; it authorizes a risk-based prohibition DOE has yet to define, so "banned" is not the right word for where things stand today. Manufacturer statements about voltage classification and market positioning are self-reported to trade press, not independently audited. And this piece covers federal procurement policy only — it says nothing about how any state or county is separately regulating the same equipment at the siting level.
