The Illinois Commerce Commission on Jan. 9 released a report identifying challenges and opportunities related to electric vehicle deployment and its impact on the grid. The report identifies high upfront costs, range anxiety, lack of charging stations, and inadequate consumer awareness as the key barriers to widespread adoption. The main benefits surrounding electric vehicles pertain to environmental and economic gains. The report summarizes comments received in response to the commission’s request for information recognizing the need for clear policy to guide efficient grid integration of EVs, ownership of charging infrastructure, appropriate rate structures, and efficient charging practices for grid stability.

The commission opened a proceeding last September gather information regarding opportunities in EV deployment following two policy sessions examining transportation electrification and policy options to tackle the new electric demand dynamics. Panelists agreed that “inefficient, uncoordinated charging” is the main obstacle to EV penetration, noting that charging during costly, peak demand times can adversely impact the grid. On the other hand, coordinated charging can smooth out intermittency from distributed resources and improve overall grid efficiency. Discussions highlighted that large-scale EV adoption could result in benefits of up to $43 billion by 2050 in the form of lower utility bills, emissions, and fuel and vehicle expenses. Decreasing battery costs and low maintenance expenses – despite high up-front costs – are making EVs more attractive compared to vehicles with internal combustion engines.  Illinois ranks sixth in the nation for the number of electric vehicles registered in the state.

Based on the input, the commission intends to explore the role of utilities, regulators, and market participants in the charging infrastructure industry and the necessary regulatory guidance.
