EVgo announced that this year, it deployed more than 40% of its DC fast-charging stations using domestically manufactured prefabricated modular skids.

The company introduced prefabricated EV chargers in 2023 and installed the first public prefabricated site in early 2024. Given that EVgo installed several hundred new DC fast-charging stalls (see Q3 2025 report), 40% should represent a few hundred stalls and a double-digit number of stations.

The main advantage of the preassembled systems is a significant reduction in installation time and cost (on average, by 15%). Additionally, the quality and reliability of a prefabricated system are higher.

To offer prefabricated charging systems with 350-kW Delta Electronics chargers, EVgo teamed up with Miller Electric Company, an electrical contractor based in Jacksonville, Florida:

“Prefabrication ensures consistent, high-quality assembly in a controlled environment by assembling all charging equipment onto a single base frame made from American steel and aluminum at Miller Electric’s facility before shipment to the installation site. Since the partnership first launched in 2023, EVgo’s expanded work with Miller Electric has supported local job creation. Miller Electric has scaled capacity at its prefabrication facility and employs more than 1,400 people in the Jacksonville area. “

The prefabricated charging systems are modular. A single system can have up to 14 stalls (up to 7 dual-head chargers, we assume). Additionally, depending on the order, other elements may be added, such as Wi-Fi infrastructure, lighting, security cameras, and canopies.

As of today, EVgo prefabricated stations have been installed in California, Florida, Georgia, Illinois, Nebraska, New York, and Texas. The first sites are under development in North Carolina, Utah, and more.

Dennis Kish, President of EVgo, said:

“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. Utilizing prefabricated modular skids from Miller Electric is key to scaling EVgo’s nationwide network.”

Pat Eliason, Group President at Miller Electric Company, said:

“By prefabricating EV skids, we’re able to deliver consistent, high-quality installations while reducing timelines and costs. This approach accelerates infrastructure deployment and supports domestic manufacturing and job creation—key pillars for a sustainable future. This collaboration with EVgo demonstrates innovation and efficiency in the EV charging industry.”.
