According to the Wall Street Journal, Proterra has sold only 550 electric transit buses since its founding in 2004. Most of the sales were underwritten by government agencies with federal grants. Proterra’s electric buses were plagued with mechanical defects and other performance issues, such as limited range and long charging times. Besides government subsidies, the company only survived as long as it had due to powerful political connections. Former Michigan governor Jennifer Granholm, Biden’s energy secretary, served on its board.
Despite all the quality issues of its EV buses, Proterra went public in January 2021 and raised $650 million, more than three times its annual revenue. A month after the company’s IPO, Biden tapped Granholm as his energy secretary. Proterra’s political connection to the Biden administration paid off in many ways.
