U.S. electric vehicle charging operator EVgo said more than 40% of the fast-charging stations it deployed this year were built using domestically manufactured prefabricated charging skids, a move the company says has reduced costs and shortened installation timelines.
The modular approach, developed in partnership with Miller Electric Company, assembles major charging components in a factory onto a single steel-and-aluminium base before transport to site. EVgo said the method has lowered average station installation costs by about 15% and helped accelerate deployment as charging demand grows.

“The prefabrication model is a win-win for EVgo because we can fast-track infrastructure deployment to meet charging demand and support workforce development in this growing industry,” said Dennis Kish, president of EVgo. “Utilising prefabricated modular skids from Miller Electric is key to scaling EVgo’s nationwide network.”
EVgo and Florida-based Miller Electric began collaborating on prefabrication in 2023. Since then, Miller Electric has expanded capacity at its Jacksonville facility, where it now employs more than 1,400 people. The companies said factory assembly improves consistency and quality by shifting complex installation work away from individual construction sites, while supporting domestic manufacturing and job creation.

Beyond core charging hardware, the prefabricated skids can integrate additional infrastructure such as lighting, Wi-Fi, security cameras and canopies before delivery. EVgo said stations deployed this year using the modular system are equipped exclusively with 350 kilowatt DC fast chargers and can charge up to 14 vehicles simultaneously, depending on site layout.
Prefabricated EVgo stations are already operating in states including California, Florida, Georgia, Illinois, Nebraska, New York and Texas, with additional sites under development in North Carolina, Utah and other locations, the company said.
