The prefabrication system is anticipated to cut average station installation time in half and save an average of 15% in station construction costs at eligible sites. With a scalable design that starts at six fast charging stalls — supporting EVgo’s focus on expanding stall counts to bolster resiliency — the prefabrication model further standardises EVgo’s construction process and station layout by utilising a modular skid.
In addition to savings on installation timelines and costs, this new approach being tested in key markets around the US includes many features to elevate the EV driver customer experience, including Wi-Fi infrastructure that can be added seamlessly to boost cellular connectivity as needed. Prefabricated skids are also future proofed to accommodate lighting and security cameras and can integrate with canopies to offer shade on sunny days and shield drivers from inclement weather.
The skid frame will also be covered with synthetic turf once installed on site, providing a layer of cushioning to help safeguard connectors that may be dropped, another key feature to further enhance resiliency. Site hosts and their customers will also benefit from a quicker construction process with less disruption.
Through prefabrication, all charging equipment, including dispensers, power cabinets and any additional necessary equipment, is assembled in a single base frame before being shipped to the fast charging site. By using this process wherever possible, EVgo expects to accelerate timelines while ensuring consistent, high-quality assembly in a controlled environment. This approach also allows EVgo to perform pre-commissioning at the fabrication facility, which is anticipated to further accelerate deployment timelines.
“There are roughly 30,000 fast chargers in the US today, and by 2030, industry analysts estimate we’ll need more than 300,000,” said Dennis Kish, EVgo COO. “Innovations like this prefabrication model are critical to scale EVgo’s network and build the infrastructure needed to meet the growing demand for public charging. Prefabricated stations can not only help us save time and cut costs, but also elevate the customer experience by providing popular features drivers want.”
EVgo’s prefabrication projects are underway at multiple locations in Florida, Nebraska, North Carolina, and Texas. The first site to be deployed using this new method is located in Texas and is anticipated to begin construction this month, with a goal of opening to the public by February 2024.
EVgo expects to expand prefabrication to additional locations throughout 2024.
