King County Metro announced plans to purchase up to 73 all-electric battery buses from Proterra at a cost of up to $55 million, starting with 20 buses totaling $15.12 million. Charging stations to support the initial orders of those buses will range from $5.5 million to $6.6 million.
The 40-foot battery buses have an estimated range of about 25 miles, with a quick charging time of just 10 minutes. Maintenance costs of all-electric buses are expected to decline versus hybrid-diesels, primarily because they have fewer moving parts, according to the agency.
