Power Electronics Starts a Houston Inverter Campus Sized for 40 GW a Year

Power Electronics broke ground on a 53-acre inverter manufacturing campus in northwest Houston, Texas, at 9220 Fairbanks North Houston Road. The Spanish manufacturer states the site will reach up to 40 GW of annual production capacity once it runs fully, and add more than 400 jobs. Two buildings of roughly 150,000 and 700,000 square feet will hold production, logistics, electronics manufacturing, R&D, training and corporate offices on one site. The company marked the groundbreaking in September 2026.

The campus is the largest expansion of the company’s US manufacturing footprint. Power Electronics builds inverters for solar generation, battery storage and data center loads. The firm describes the plant as its most automated inverter factory to date.

“For the first time in many years, the United States will be able to meet its growing need for sustainable power generation capacity and energy resilience through local manufacturing, supported by the most advanced technology in the world,” said David Salvo, chief executive of Power Electronics.

Houston lifts the company’s worldwide capacity to about 105 GW a year. That total counts a parallel expansion in Llíria, Spain, where the plant grows from 100,000 to 150,000 square meters. Power Electronics says the US site will serve the United States and the wider Americas market.

What the announcement leaves out

Neither the company statement nor the trade coverage put a dollar figure on the investment. No construction schedule, no production start date and no state or county incentive package appeared in any account. The capacity number itself is not clean either. Local outlet Hoodline reported 35 GW rather than 40 GW. The 40 GW figure carries the qualifier “up to” in the company’s own wording, and it describes a fully built site rather than day-one output.

Why It Matters

Inverters sit between a solar array or a battery and the grid, so inverter supply gates how fast projects reach commercial operation. Most US utility-scale equipment ships from plants abroad. Section 232 duties on polysilicon, wafers, cells and modules take effect on December 4, 2026, which raises the landed cost of imported hardware for the same developers who buy these inverters. A domestic inverter line changes where part of that supply chain sits. The figure to watch is not the 40 GW nameplate. It is the first shipping date, which nobody has given.

Critical Perspective

The 40 GW number describes a finished campus, and nothing in the announcement says when the first inverter ships. Power Electronics gave no investment total, no construction schedule and no incentive package, which are the three figures that usually show whether a groundbreaking turns into output. One outlet covering the same event reported 35 GW, and the company’s own wording is “up to.” Read the nameplate as a ceiling the site reaches years after the ribbon, not as capacity arriving on the grid this decade.
