Understanding how to eﬀectively influence electric vehicle (EV) charging behavior is critical for managing electricity grids powered by high levels of variable renewable generation. We present results from a large-scale natural field experiment conducted in the United Kingdom, involving approximately 110,000 EV customers and 60% of the country’s public charging infrastructure. Within this network, we applied a price decrease to approximately one-fifth of chargers to bring their prices closer to the marginal cost of electricity in low-cost hours in Great Britain. Customers were randomly assigned to diﬀerent price levels, allowing us to estimate the causal eﬀect of price on charging demand and derive elasticities of short-run behavioral responses. Customers were highly responsive to price: a 40% reduction in charging costs increased platform-wide charging activity by 117%, while a 15% price cut led to a 30% increase. Decomposing the increase in charging, we estimate that approximately half reflected substitution between charging apps. Our findings suggest that dynamic pricing for public EV charging generated large consumer welfare gains.
