Within SPP’s service territory, 32% of vehicle stock is electrified by 2050, but 50% of vehicle stock nationally based on the state-differentiated adoption rates. Higher rates of electrification of medium-duty vehicles are the result of better economics for high mileage vehicles and predictable duty cycles that create a compelling case for electrification.
