Cathy Zoi, CEO of EVgo, pays a lot of attention to the economics of public electric vehicle charging, both in terms of the widely varying upfront costs from location to location, and the long-term calculations that go into making sure their revenue exceeds their costs over their lifetime. “We have a first-mover advantage, but we also have a first-learner advantage,” she said, with data collected from about 1,500 fast chargers across 800 locations to date. That's allowed the decade-old EV charging provider to develop “proprietary utilization forecasting tools” aimed at ensuring that the early years of a fast-charging site, when relatively few EVs are on the roads to use it, can eventually be made up by the end of its life as EVs proliferate in its region. “That’s some of our secret sauce.”
