Electric Buses: The BYD-Proterra Competition Reshaping U.S. Transit
How Chinese manufacturing prowess and American policy responses are shaping the future of electric public transit in the United States.
The electrification of America's bus fleet has become an unexpected battleground in U.S.-China economic competition. At the center: BYD, the Warren Buffett-backed Chinese manufacturer, and Proterra, America's leading electric bus maker. Their competition offers lessons about industrial policy, supply chains, and the complexities of the energy transition.

BYD's American Strategy
BYD (Build Your Dreams) entered the U.S. market with a classic playbook: aggressive pricing enabled by Chinese government subsidies and vertically integrated manufacturing. The company opened a factory in Lancaster, California, positioning itself as a local manufacturer while leveraging its Shenzhen-based supply chain for batteries and components.
The strategy worked. BYD won contracts with transit agencies in Los Angeles, Seattle, Denver, and dozens of other cities. At its peak, BYD claimed the largest share of America's nascent electric bus market, undercutting Proterra on price while offering competitive range and performance.
The Policy Response
BYD's success triggered a policy backlash. In 2019, Congress passed legislation restricting federal transit funds from purchasing buses from Chinese state-influenced companies—effectively a "BYD ban." The legislation reflected bipartisan concerns about supply chain security, intellectual property, and the strategic implications of Chinese dominance in transit electrification.
Proterra and other American manufacturers lobbied aggressively for these restrictions, arguing that Chinese subsidies created unfair competition. The debate highlighted tensions between climate goals (which favor rapid, low-cost electrification) and economic security concerns (which prioritize domestic manufacturing).
The Broader Implications
The electric bus competition previews similar battles in EVs, batteries, and clean energy equipment. It raises difficult questions: Can America build competitive clean energy supply chains without Chinese components? How should policymakers balance environmental urgency against economic security?

Despite the federal restrictions, BYD maintains a foothold through contracts signed before the ban and in markets without federal funding involvement. Proterra, meanwhile, expanded capacity but faced its own challenges—eventually filing for bankruptcy in 2023, though its bus division continues operations under new ownership.
The U.S. electric bus market remains fragmented, with New Flyer, Gillig, and newer entrants competing alongside legacy players. The Inflation Reduction Act's manufacturing incentives may reshape the competitive landscape once again, potentially favoring companies with American supply chains.
