California semi truck electrification: Preliminary assessment of infrastructure needs and cost-benefit analysis

Electrification presents a major opportunity to address greenhouse gas emissions and air pollution from heavy-duty trucking in California. Here we provide a preliminary estimate of infrastructure needs and economic impacts of electrifying combination trucks in California. Electrifying CA trucking is estimated to require ~750 charging stations at a $10.8B upfront investment; baseline costs of electrification (including charging infrastructure, grid upgrades, electricity, and truck electrification) is estimated to be $5.7B/yr; baseline savings on diesel, GHG emissions, and air pollution is estimated to be $7.8B/yr; net savings from electrification of combination trucking in CA is estimated to be $2.2B/yr.
