Eaton has signed an agreement to acquire Resilient Power Systems Inc., accelerating its entry into the growing market for solid-state transformer (SST) technologies with critical applications across EV infrastructure, data centers, and energy storage.
Resilient Power, based in Austin, Texas, develops medium-voltage SSTs capable of delivering compact, high-efficiency DC power for ev charging depots and emerging DC-based applications. The company’s ultra-compact systems connect directly to the grid, eliminating the need for traditional substation upgrades and significantly reducing deployment costs and complexity.
“Resilient’s medium voltage solid-state transformers are a next-generation solution in high-power, direct current (DC) applications in the EV market – and there’s huge opportunity for future applications in data centers, port electrification and battery energy storage,” said Mike Yelton, president, Americas Region, Electrical Sector at Eaton, in a July 2025 press release. “By leveraging Eaton’s manufacturing capabilities, field service organization and commercial scale, we’re confident we can expand the market for this innovative technology.”
The deal marks a significant step for Eaton as it seeks to strengthen its portfolio in fast-growing electrification markets—particularly as demand for grid modernization, EV fleet infrastructure, and DC microgrid solutions surges.
Key opportunities stemming from the acquisition include:
Accelerated EV Fleet Charging
Resilient’s technology enables EV fleets—such as those operated by logistics and municipal services—to install charging stations quickly and cost-effectively. This addresses one of the most persistent bottlenecks in electrification: the time and expense of upgrading grid infrastructure.
Data Center Power Efficiency
With global data center energy demand projected to double by 2030, the acquisition positions Eaton to provide SST-based solutions that boost power density and reduce energy conversion losses. These innovations could support hyperscale operators and co-location facilities looking to decarbonize and improve uptime.
Growth in Energy Storage and Port Electrification
Resilient’s SSTs can also improve integration of battery systems and high-voltage DC use cases, such as shore power for electrified ports—a key emissions reduction target in international shipping hubs.
Eaton’s acquisition of Resilient comes as competitors such as Siemens and ABB also invest in SST technologies to support distributed energy resources and flexible grid solutions. By owning both the digital platform (Brightlayer) and hardware innovations, Eaton is aligning itself for vertical integration amid the broader energy transition.
The solid-state transformer market is expected to grow at a compound annual growth rate (CAGR) of over 20% through 2030, driven by electrification, microgrids, and decentralized energy needs. VC backing from Energy Transition Ventures further signals confidence in Resilient’s market relevance and technology maturity.
The acquisition is expected to close in Q3 2025, pending customary closing conditions.
