Ten new electric buses are coming to Sonoma County. The county will purchase ten battery electric transit buses to replace ten gas buses. The ten new buses, which are scheduled for delivery between July 1 and August 31 next year, are in addition to six all-electric buses expected to arrive in June. There are currently three all-electric buses in the county’s 49-bus fleet. With this purchase, Sonoma County Transit will have approximately 40 percent of its fleet electrically powered.
