Hitachi Energy expands power semiconductor production at Swiss site - Hitachi Energy

Hitachi Energy has initiated a significant expansion at its power semiconductor manufacturing site in Lenzburg, Switzerland, marking a key step in its global strategy to meet rising demand for semicon... Read original →

Hitachi Energy’s expansion in Lenzburg isn’t just capacity scaling—it’s a strategic bet on the inflection point of global grid digitalization. Technically, it accelerates SiC/GaN adoption in HVDC and storage systems, pressuring upstream wafer suppliers to improve yields on 6-inch+ substrates while pushing downstream grid equipment toward AI-orchestrated, modular architectures. Regulatory-wise, Switzerland’s neutrality and stable power shield operations from U.S.-EU chip subsidy geopolitical strings, though high labor costs and stringent environmental rules will pressure near-term margins. Facing price wars from Infineon, ABB, and Taiwan, China-based IGBT makers, Hitachi Energy is pivoting to system-level bundling—integrating HVDC, storage, and AI-driven grid management—to shift competition from components to ecosystems. Within 18 months, this site will anchor Europe’s green infrastructure, elevating power semiconductors from passive components to core enablers of an intelligent energy OS.
