EVgo's Warren flagship puts its 400-stall charging plan into view

EVgo and General Motors promised 400 fast-charging stalls at flagship locations in September 2024. The brief called for canopies, pull-through access, security cameras and chargers rated at up to 350 kW, with the first location expected in 2025. Warren, Michigan now has the clearest example of that design, albeit later than originally forecast.

The host of The Network Architect Channel, who tracks new DC fast-charging sites through the federal Alternative Fuels Data Center database, said in a late-July video that the lack of visible progress had led him to dismiss the programme as vaporware.

A contractor's LinkedIn post changed his mind. It showed a lit canopy over pull-through stalls in a Meijer car park across Mound Road from GM’s Global Technical Center. EVgo formally announced the site on 11 August, calling it its newest flagship rather than its first. The distinction matters: Warren lifted the programme’s nationwide total beyond 40 stalls.

The Warren station replaced a smaller six-port installation commissioned in May 2023. Its successor has six Delta Electronics dispensers serving 12 pull-through stalls, all listed by EVgo at up to 350 kW. The operator's live station page currently shows four CCS dispenser pairs and two NACS pairs.

Mike, who reviews charging hardware on his Mike the Car Geek channel, walked the lot before the ribbon-cutting and examined the electrical equipment. He identified a 1,500 kVA transformer, the same rated size he had seen at a Rivian Adventure Network site about seven miles away. Six 350 kW cabinets add up to 2,100 kW of nameplate charger capacity, so a full house of power-hungry vehicles would have to share what the site can supply. That is routine power management rather than evidence of a fault, but it is a practical limit absent from a rendering.

The connector mix also changed between Mike's pre-opening visit and the live listing. He saw only one NACS-equipped dispenser at the time. EVgo now lists two, useful context for a site opposite a GM campus as the company's newer EVs adopt the connector.

The flagship format is aimed at retail dwell time. In an Automotive News interview, EVgo chief executive Badar Khan kept returning to the grocery run: families shop regularly and spend enough time inside for a useful fast charge. Meijer’s Warren store is open from 6am to midnight, while EVgo lists the charging site itself as open 24 hours.

The company is also building a separate highway network with GM Energy and Pilot Flying J. That collaboration has surpassed 1,300 stalls at 300 travel-centre locations in 40 states. Warren serves a different job: turning an ordinary shopping trip into charging time, with a canopy and pull-through lanes that make the stop easier for larger vehicles and trailers.

Khan also drew a distinction between the economics of EVgo’s charging network and those of the company funding its expansion. He told Automotive News that the network was profitable, while the company remained loss-making because of growth spending, and forecast that it could generate enough cash to cover operations and expansion within roughly a year. That is a forecast, not a result, and the pace of new construction will test it.

EVgo says more than 40 flagship stalls are now operating and expects to exceed 100 by the end of 2026, with builds in California, Florida, Georgia, Illinois, Michigan and Texas. The original commitment was 400 stalls, not 400 stations. Because flagship locations average up to 20 stalls, comparing the two as site counts would exaggerate the size of the programme by an order of magnitude.

The wider EVgo network ended the second quarter with 5,380 stalls at more than 1,200 locations. Against that footprint, 40 flagship stalls remain a small trial of a more elaborate format. Prefabrication is meant to help the larger sites arrive faster: EVgo says components can be assembled off-site, reducing work and commissioning problems in the car park.

GM public-charging chief William Hotchkiss said the Warren site demonstrates what automakers, networks and retailers can deliver together. The driver's version is less ceremonial. The important questions are whether there is a roof, whether a trailer fits, whether the cable matches the car and whether the charger starts. Warren is a credible answer to those questions. It is also only a fraction of the 400-stall promise.
