Sep 3, 2025 07:19 AM ET
  • Ingeteam powers up Texas with its largest U.S. solar installation, energizing 140,000 homes and advancing Parliament Energy's ambitious 2.7-GWdc solar portfolio.

Ingeteam has commissioned the 640-MWdc Parliament Solar plant in Waller County, Texas, for Parliament Energy. The Spanish company provided 149 liquid-cooled central inverters integrated into 80 transformer stations, marking its largest photovoltaic installation in the U.S. The solar farm is expected to generate approximately 1,100 GWh annually, enough to power around 140,000 homes.

Parliament Energy, supported by EnCap Investments and Mercuria Energy, aims to develop a 2.7-GWdc portfolio of utility-scale solar assets. Ingeteam has supplied over 6 GW of solar inverters and energy storage in the U.S., with plans for further collaboration with Parliament Energy.
