The Road to Transportation Decarbonization: Readying the Grid for Electric Fleets

Surface transportation will soon be powered by the grid. We have already begun plugging in our personal cars; now, medium and heavy-duty vehicles (MHDVs) – trucks, buses, and vans – are starting to rely on the electric grid too. The transportation sector is the largest source of greenhouse gas emissions in the United States, and the transition to electric vehicles will be an essential element of our path forward to meet climate goals.

To understand what will be needed from utilities to support the electrification of MHDVs, National Grid and Hitachi Energy partnered on a case study of the potential demands and grid impacts of electric fleets. The study leads to insights and recommendations to help utilities, policymakers, and the transportation industry decarbonize fleet vehicles.
