This 2020 Brattle Group presentation provides an assessment of the investments needed across the electric power sector to support the deployment of 20 million EVs in the U.S. by 2030 with a focus on EV charging infrastructure. The report finds that $75–125 billion of investment is needed across the electric power sector to serve 20 million EVs, which vehicles will add 60–95 TWh of annual demand and 10–20 GW of peak load to the system and require 12–18 GW of renewable capacity and 1–2 million public chargers to serve them. Utility investments will be therefore necessary across the supply chain, including $30–$50 billion for generation and storage, $15–$25 billion for transmission and distribution upgrades, and $30–$50 billion for EV chargers & customer-side infrastructure.
The report recommends that industry planners and policymakers take a three-pronged approach to planning for significantly greater EVs, including (1) proactively developing an EV roadmap, (2) crafting an EV regulatory strategy, and (3) identifying win-win-win solutions that address market barriers.
