National Energy Installers has designed and installed 350+ megawatts of commercial energy infrastructure across California in just four years. The projects below span healthcare campuses, industrial and manufacturing facilities, data centers, and commercial real estate, each engineered around the specific demand charges, uptime requirements, and site constraints of that sector. From solar and battery storage to microgrid controls and power distribution, every system is designed, permitted, and delivered by one integrated team.
