How can utilities meet DCFC demand for EV charging and become profitable? Some utilities are using "preferred" or "limiter" rates. Regardless, were everyone in the entire country all suddenly to become EV users, this provides an example of how woefully unprepared utiltiies are to meet the electricity demands for EVs.
"Demand charges continue to be a drag on high voltage, direct current electric vehicle charging ports, according to new research by the Great Plains Institutes for the Midcontinent Transportation Electrification Collaborative. Economic disadvantages include both profit and the ability to attract third-party investment, according to the report, which looked at electric rates and potential direct current fast charging (DCFC) infrastructure along the Minnesota-to-Michigan corridor on Interstate 94, operating between 50 kW and 350 kW. Lower-wattage stations were significantly more likely to be profitable. The Midcontinent region currently has 425 DCFC plugs, according to GPI's research, but the region needs more than 4,000 DCFC plugs by 2030 in order to grow EV adoption, according to the National Renewable Energy Laboratory."
