Dr. Kontou presented at the Conference on Transportation, Economics, Energy and the Environment, held at the University of Michigan on Friday October 19th, 2019. Ria presented her published work on electric vehicle fast charging rates, which uncovers spatial heterogeneity and variations of electricity cost for different scenarios of fast charging station size and use based on over 7,500 commercial and industrial electricity tariffs available during 2017 across the United States. This study identifies opportunities to mitigate high electricity costs, which fast charging infrastructure operators bear, through appropriate electricity rate-making.
