The White House Grid Order Bans Nothing Yet: Korean Makers Rallied

The White House issued Executive Order 14420 on Wednesday, August 26, declaring a national emergency over equipment connected to the U.S. electric grid. Most of the headlines the next morning ran the same sentence: the United States has banned foreign-made grid equipment.

The text does not say that. The order imposes no prohibition; it builds the frame in which one could be imposed, and hands the rule-writing to the Department of Energy on a 120-day clock. Until those rules appear — December 24 — no product, no manufacturer and no country has actually been shut out.

Even so, four Korean power equipment makers rose together in Seoul the day after the signing. A document that bans nothing setting a price within 24 hours is the subject of this piece.

What the Order Actually Says

The order draws its authority from the International Emergency Economic Powers Act and the National Emergencies Act. The hardware list is broad: transformers, reactors, capacitors, high-voltage circuit breakers, protective relaying, metering equipment, grid-connected inverters, battery energy storage systems, uninterruptible power supplies, generation turbines, and the industrial control systems and software that run all of it.

There is a threshold. The order reaches transmission rated at 69 kV and above, plus the generation assets tied to it. Low-voltage distribution running to homes and businesses sits outside.

The target is defined as a "covered foreign entity": a manufacturer owned by, controlled by, or subject to the jurisdiction of a government under a U.S. arms embargo or sanctions regime. In practice that maps to the 24 countries listed under the arms export regulations. The order names none of them.

The prohibition is conditional as well. A transaction can be stopped only once the Secretary of Energy determines it carries an "undue risk of sabotage" or of supply disruption. Before that determination, nothing is stopped.

A Statement or an Instrument

Three questions have to be asked separately in a regulatory story, because headlines routinely collapse all three into one sentence.

First, what exactly was said? The order is a statement of intent and a delegation of authority. Not "we are banning," but "we are establishing the power to ban, on these conditions."

Second, is there an instrument that makes the preference binding? Not today. There is no rule in force, no published scope, no named manufacturer. The department has 120 days.

Third, does the existing instrument's scope actually reach the event? Partly. The order does not automatically cover installed equipment, but it does grant the Secretary authority to impose conditions on the continued use, maintenance and updating of gear already in the ground. Norton Rose Fulbright reads that authority as wide enough to require installed equipment to be isolated, monitored or removed, with phased implementation expected so the grid keeps running.

The Same Order Was Signed Six Years Ago

This is not a first draft. Executive Order 13920, signed May 1, 2020, covered the same sector on the same rationale in similar language. In the FAQ the Department of Energy published afterward, it wrote:

"As of today, no equipment is prohibited."

In December 2020 the department issued a narrow prohibition order covering critical defense facilities only. Biden suspended the order for 90 days on his first day in office, the department revoked the prohibition order in April 2021, and 13920 was never applied again. In six years the only binding instrument produced was a narrow order that stood for three and a half months.

The Exposure and the Scope Are Not in the Same Place

The order sorts equipment by the government a manufacturer answers to, not by the country it ships from. That distinction means the place the U.S. is most exposed is not the place the order bites hardest.

On transformers the dependence is geographically scattered. Roughly 80% of the large power transformers used in the U.S. are imported, and domestic production covers only about a fifth of annual demand. But most of those imports come from Mexico, South Korea and Europe. China ranks sixth as a U.S. supplier of completed large transformers; its share of U.S. transformer component imports was 15% by value in 2023, or $375 million.

On batteries and inverters the picture inverts. According to the International Energy Agency, China produces more than 80% of world output in certain grid equipment categories, lithium-ion cells included. That is why the order lists battery energy storage systems and grid-connected inverters by name.

So the order's direct effect on the transformer market is limited and its potential effect on the battery and inverter market is large. The names that rose, however, were the transformer makers. Explaining that requires looking at the queue rather than the price.

The Arithmetic of the Queue

For three years U.S. grid equipment has been a market cleared by delivery date rather than by price. In Wood Mackenzie's second-quarter 2025 survey, average delivery for a power transformer ran 128 weeks; generator step-up transformers ran 144 weeks, with some specialized orders reaching four years.

Prices moved the same way: since 2019, power transformers are up 77%, distribution transformers between 78% and 95%, and generator step-up transformers 45%. Over the same period demand for power transformers rose 119% and for generator step-up transformers 274%. In that market the buyer has no bargaining power. The buyer has a place in line.

The length of that line is what lets an unwritten rule set a price today.

Where the Market Looked

On August 27 in Seoul, four manufacturers rose at once: HD Hyundai Electric up 9.28% to ₩801,000, Sanil Electric up 11.76% to ₩197,700, Hyosung Heavy Industries up 6.04% to ₩2,966,000, and LS Electric up 4.71% to ₩211,000. The Kospi gained more than 2% the same day.

Their U.S. exposure is not new. The combined order backlog of Korea's three largest power equipment makers stands at ₩36.73 trillion, roughly $25.7 billion. Hyosung Heavy Industries' backlog rose 63% year over year to ₩17.5 trillion, and the company supplies close to half of the 765 kV transformers in U.S. grids. LS Electric's backlog rose 81.5%, including roughly ₩1.2 trillion of North American data center orders.

The U.S. side looks different. The names listed as winners after the order did not rise: GE Vernova fell 3.39% from $921.50, Eaton 2.88% from $404.06, Enphase Energy 5.89% from $36.94 and Tesla 1.95% from $347.89. GE Vernova fell another 3.33% the following day, attributed not to the order but to an announced chief financial officer change and profit-taking after a months-long run.

That chart is live and does not show the order's effect; it shows where the largest U.S. name in grid equipment stands today. Across those same two sessions, semiconductor tariff reports were pressuring industrials and Fed Chair Kevin Warsh's inflation warning had lifted expectations of a rate hike. Pinning a single day's move on a single headline would assert a causal link the sources do not make.

The instructive part is this: the side the order rewarded is not the side it claims to protect. A document signed to strengthen domestic manufacturing priced a group of foreign suppliers first. In the short run, capacity vacated by a restriction is taken up not by American plants but by the out-of-scope suppliers nearest the front of the queue. The roughly $2 billion committed to North American transformer capacity — including Hitachi Energy and Siemens Energy lines — is expected to come online in 2028.

The Other Side

What Is Left

Two dates sit on the calendar. On December 24, 2026 the Department of Energy publishes its rules; the list of covered countries, the test for determining the origin of hardware and firmware, and whether a pre-qualified vendor list is created will all be settled in that text. At 180 days, proposed revisions to federal acquisition rules follow.

The definitional problem Bridget Bartol of the National Electrical Manufacturers Association points to is the origin test itself: when firmware is written in one country and compiled in another, which one is the source? That, she says, is where there is "a need for a lot more clarity".

Behind all of it sits the $1.1 trillion U.S. electric utilities plan to invest between 2025 and 2029. In a supply chain where a single American company produces the grain-oriented electrical steel transformers require, where the scope line is drawn will decide how much of that investment can be energized on schedule.

Spreading supply chain risk means not depending on one cheap supplier; the logic of diversification applies to procurement as much as to a portfolio. December's text will show for whom that diversification has become mandatory.

This piece draws on the text of the executive order published by the White House, coverage of its scope by Utility Dive and pv magazine, the legal reading published by Norton Rose Fulbright, closing prices from the Korean market reported by Seoul Economic Daily, Wood Mackenzie's delivery-time survey, and import data compiled by ChinaTalk. The number of covered countries does not appear in the order itself; it is a legal interpretation based on the arms export list. Share price moves are the data of the day reported, and the sources do not establish causation.
