How grid reinforcement costs differ by the income of electric vehicle users

S. A. Steinbach and M. J. Blaschke

This groundbreaking study by Sarah A. Steinbach and Maximilian J. Blaschke reveals alarming cost disparities in electric vehicle charging infrastructure, highlighting that wealthier neighborhoods could face investments up to 33 times greater than lower-income areas. Could this lead to a new kind of energy inequity? Join us as we explore solutions through dynamic pricing and equitable subsidies.

Abstract
The simultaneous charging of numerous electric vehicles (EVs) could overload grids. This study uses power flow simulations with real-life driving profiles to predict cost asymmetries in grid reinforcement, finding that higher-income neighborhoods may require up to 33 times more investment than lower-income ones. This cost disparity, often redistributed via electricity price increases, could exacerbate energy inequity. Policy recommendations include dynamic pricing, income-based EV subsidies, and improved charging access.
