Founded in Wake Forest, NC in 2000, PowerSecure has grown to 1700 employees and is now a Southern Company subsidiary. The company provides energy solutions in distributed generation, energy storage and renewables, energy efficiency and utility infrastructure. 

PowerSecure expanded into its new 260,000 square foot campus in Durham County in 2017. The decision to stay and grow in the Research Triangle region was made for several reasons, including its ability to attract and retain top talent, and close proximity to several partners, suppliers and vendors. The company's location near the Raleigh-Durham International Airport also makes it easy for customers to visit its facility where it showcases new technologies on its very own microgrid. 


"Trilliant made the decision to relocate our global headquarters from Silicon Valley to Research Triangle Park in 2017," says Trilliant Chairman and CEO, Andrew White. "The area is globally a recognized technology community, especially in the energy, smart grid, and IoT space. By establishing our global headquarters in the Research Triangle area, we've added our footprint to the other world leading technology companies as we continue to advance and innovate in the energy space. We've found some of the brightest and most innovating talent for a high-tech company like us."
