Trump grid-equipment order cuts Sungrow 12.7% as China weighs retaliation

President Donald Trump declared a national emergency over foreign power-grid equipment Wednesday, signing Executive Order 14420 that lets the Energy Department block imports and force replacement of Chinese-made transformers, generators and battery storage.

"The US federal communications commission's measures are typical market distortion and unilateral bullying," China's commerce ministry said, vowing to "resolutely counter" actions that damage Chinese trade interests.

Sungrow Power, the inverter leader, fell 12.68 percent to a market value of 203.9 billion yuan Thursday, leading a broad decline in A-share power transmission equipment stocks. China accounts for roughly 80 percent of global solar and battery inverter manufacturing capacity, according to International Energy Agency data.

The Energy Department has 120 days to publish implementing rules, and within 180 days the energy secretary must recommend federal procurement changes prioritizing US-made infrastructure. Transformer lead times stretch beyond two years, so the gap between aggressive replacement mandates and risk-based remediation is enormous — in both cost and grid reliability.

The order targets the bulk-power system — large-scale generation and transmission infrastructure — not local distribution networks. Covered equipment spans substation transformers, large generators, industrial control systems, battery energy storage systems, grid-connected inverters, turbines, and associated software, firmware and remote-access capabilities.

The Energy Department can prohibit acquisition, importation, transfer or installation of foreign-produced equipment if it determines the transaction involves a covered foreign entity and poses an unacceptable security risk. For equipment already operating on the grid, the energy secretary can require it to be identified, isolated, monitored, secured, disconnected, replaced or removed.

The order builds on escalating US actions. Trump signed a previous emergency declaration in January 2025 addressing bulk-power vulnerabilities. In July, the FCC added foreign power inverters and advanced robotics to its Covered List, restricting their use in federally funded projects. The precedent dates to a 2020 executive order that first flagged the risks, though implementation stalled under the Biden administration.

The order does not impose a blanket ban. Restrictions depend on Energy Department determinations involving covered foreign entities and national security risks, and the department can establish a list of pre-qualified equipment and vendors. The 120-day rulemaking window will determine how aggressive implementation becomes.

For utilities, compliance will not be cheap or quick. Transformers are custom-built, weigh hundreds of tons, and have lead times that can stretch beyond two years even under normal conditions. The order directs officials to weigh reliability and safety, the availability of secure replacement equipment and continuity of essential service before requiring equipment to be replaced.

The flip side is a potential windfall for domestic manufacturers. With foreign competitors facing new barriers, US-based producers of transformers, inverters and grid control systems stand to capture market share they have been losing for decades. Within 180 days, the energy secretary must recommend changes to federal procurement rules prioritizing US-manufactured infrastructure.

The renewable energy sector faces a particularly complex adjustment. Solar and battery storage projects have been built around Chinese supply chains for years because no other country manufactures these components at comparable scale and cost. If compliance timelines are tight, some regions could face difficult choices between maintaining reliability standards and meeting replacement deadlines — creating the very vulnerabilities the order is designed to prevent.
