EXECUTIVE ORDER 14421 · SIGNED AUGUST 26, 2026
BE READY IN 100 DAYS.
A NATIONAL EMERGENCY NOW GOVERNS WHICH BATTERY EQUIPMENT YOU'RE ALLOWED
TO INSTALL.
The White House has declared a national emergency over the US bulk-power system, and for the first time, battery energy storage systems and their control electronics are explicitly named in the restricted equipment list. Here's what the order actually says, and what it doesn't.
SUMMARY
WHAT THE ORDER ACTUALLY DOES
ORDER 14421
Executive Order 14421 declares a national emergency under the International Emergency Economic Powers Act and the National Emergencies Act, citing the risk that foreign-supplied equipment on the bulk-power system could carry hidden remote-access capability or be disrupted through supply-chain interference.
In practice, it gives the Secretary of Energy authority to prohibit a transaction (an acquisition, import, transfer, or installation) of qualifying equipment, once two conditions are both met: the equipment is tied to a "Covered Foreign Entity," and the Department of Energy determines the specific transaction poses an undue security risk. The prohibition applies to transactions initiated after August 26, 2026, and can be applied to a whole class of transactions, not just individual ones.
WHAT’S ON THE RESTRICTED LIST
The order defines "bulk-power system electric equipment" broadly. Battery energy storage systems are named explicitly, alongside grid-connected inverters, protective relaying, industrial control systems, and related hardware.
WHAT IS AFFECTED
software
firmware
remote-access capability
maintenance services
Notably, the restriction doesn't stop at physical hardware. It reaches "any critical component, software, firmware, digital service, maintenance service, or remote-access capability" tied to the equipment, which puts BMS control software and cloud-connected monitoring squarely in scope, not just the metalwork.
→ Local distribution equipment is explicitly excluded. The order targets the bulk-power system (generation-linked and transmission-linked infrastructure) not equipment used purely for local grid distribution.
IT ALSO EFFECTS EQUIPMENT YOU'VE ALREADY INSTALLED
IMPORTANT TO KNOW
THIS ISN'T LIMITED TO FUTURE PURCHASES:
The Secretary of Energy can impose conditions on foreign equipment acquired or installed before the order was signed: including requirements to identify, isolate, monitor, secure, disconnect, replace, or remove it.
Before ordering disconnection or removal, the Secretary is directed to weigh grid reliability, the availability of secure replacements, and continuity of service, and may phase in compliance over time.
Existing contracts don't provide automatic protection from this.
WHO COUNTS AS A “COVERED FOREIGN ENTITY”?
The order defines this as a country, or a person controlled by one, that's already under a US arms embargo or sanctions regime, or one the Secretary of Energy separately determines is acting against US national security or foreign policy interests.
→ No specific countries are named in the order itself. The Department of Energy has 120 days from signing to publish implementing rules and make those determinations. This order follows a narrower 2020 version that focused on transmission and generation equipment and was widely understood at the time to center on China-linked suppliers. This version significantly expands the equipment list to explicitly include battery storage for the first time.
WHAT THIS MEANS IF YOU BUILD
OR OPERATE STORAGE
NEW SOURCING CARRIES OPEN RISK
Purchase orders placed with a restricted supplier after August 26, 2026 could later be caught once DOE issues its determinations — even if the deal looked fine when it was signed.

INSTALLED FLEETS AREN'T AUTOMATICALLY SAFE
DOE has authority to require disconnection, isolation, or replacement of equipment already in the ground, with phased timelines.
BEING PRE-QUALIFIED IS A REAL ADVANTAGE
Suppliers and equipment on DOE's future pre-qualified list skip the case-by-case review entirely. It is worth factoring into vendor selection now.

FINANCING AND INSURANCE WILL FOLLOW
Lenders, insurers, and interconnection agreements increasingly reference equipment provenance — expect this order to accelerate that trend.
THE MOST IMPORTANT DATES
The order sets deadlines for the Department of Energy to turn this from a declaration into enforceable rules.
TIMELINE
26 AUGUST 2026
Order signed, national emergency declared
Executive Order 14421 takes effect. Prohibitions apply to transactions initiated on or after this date, once DOE makes the required determinations.
~ 24 DECEMBER 2026
(120 DAYS)
DOE implementing rules due
The Department of Energy is directed to publish the rules, and specific entity and equipment determinations, that operationalize the order.
ONGOING
Identification of high-risk installed equipment
DOE is tasked with identifying already-installed equipment that poses a risk and recommending remediation steps to the White House.
22 FEBRUARY 2027
(180 DAYS)
Federal procurement rule changes proposed
DOE recommends revisions to the Federal Acquisition Regulation prioritizing US-manufactured energy infrastructure for federal purchases.
ROLLING
Pre-qualified vendor list (optional)
The Secretary may publish a list of pre-qualified equipment and vendors that are exempted from the restrictions — a list worth getting ahead of.
The order's concern is not the steel or the cells. It is hidden remote access, firmware you did not write and a maintenance channel you do not control. In a battery energy storage system, that is the BMS: and it is the one part you can replace without touching the racks.
The measures DOE can impose on installed equipment run from identify and monitor, through isolate and secure, to disconnect and remove. Replacing the control electronics is the heaviest of them that still leaves your asset earning.
YOU CAN CHANGE THE CONTROL ELECTRONICS WITHOUT CHANGING THE BATTERY.
DROP-IN REPLACEMENT · INSTALLED AND ORDERED FLEETS
Same rack, same cells, same footprint
Up to 1500 VDC, matched connector and voltage class, CMB channels adapted to your module.A control path that answers to you
Firmware, update channel and monitoring engineered in Munich and produced in Europe.Weeks off the shelf, months adapted
Where your module fits our standard 64-channel boards, we ship from the existing range. Where it does not, a custom CMB follows in months, not model years.
→ What this does not do:
a European BMS does not make a foreign-manufactured system domestic.
It removes the remote-access and firmware risk the order names. Whether a specific site satisfies
DOE remains a case-by-case determination under rules still being written.
WILL THIS VOID MY CELL WARRANTY?
Usually not, and we have done this before.
A cell warranty is tied to the original BMS for two reasons: that BMS enforces the operating envelope the cells were warranted against, and it produces the evidence a claim is settled on. A replacement that does both can carry the warranty. We have worked directly with cell manufacturers to agree the envelope, hold the system inside it, and log to the standard they accept when a claim is assessed.
THE WARRANTY
EO 14421 also reaches maintenance services and remote-access capability, not only hardware. If your supplier's service channel is restricted, your warranty is already impaired: by the regulation, not by the retrofit.
Send us the cell datasheet and the warranty conditions. We will tell you what we can hold.
