More California cities are electrifying their transit fleets. Stockton and Porterville recently placed orders with Proterra for two of its new Catalyst battery-electric buses, with funding from the San Joaquin Valley Unified Air Pollution Control District.

Electric bus-maker Proterra says its Catalyst is the most efficient 40-foot transit bus on the market – at 22 MPGe, it’s nearly six times more efficient than the diesel buses it will be replacing. With these latest orders, Proterra now has firm orders for 110 units on its books, as well as 323 more on option.

“As the first transit agency in Northern California to have operated fully-electric buses, we’re grateful for the District’s funding and the opportunity to expand our electric bus fleet with Proterra,” said Donna DeMartino, CEO of the San Joaquin Regional Transit District.

“With perpetual air quality challenges in the Valley, we’re grateful for the funding provided by the San Joaquin Valley Air Pollution Control District and pleased to integrate Proterra’s zero-emission buses into our transit system,” said Richard Tree, Transit Manager for Porterville Transit.

“With California representing nearly half of the US bus market and the Air Resource Board setting a goal of operating 100% zero-emission bus fleets by 2040, the state is inaugurating a quiet electric vehicle market transformation,” said Ryan Popple, CEO of Proterra.
