Stockton and Porterville, using funding from the San Joaquin Valley Unified Air Pollution Control District, placed orders for four more Proterra electric buses.

Each city ordered two 40' Catalyst transit buses, although the press release did not provide details whether those are the long-range version or perhaps maybe short-range version with fast charging.

Proterra announced that the total number of orders (completed and new) hit 110, while 323 options were contracted to bring total sales potentially to 433.


"San Joaquin Regional Transit District (RTD), which serves more than 687,744 people in San Joaquin County, will be ordering an additional two Catalyst buses to provide clean, reliable, and efficient bus rapid transit for the region."

Donna DeMartino, General Manager/CEO at RTD said:

"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."


"Tulare County's Porterville Transit also has plans to procure two Proterra 40' Catalyst buses to inaugurate the Southern Valley's first electric transit bus service for approximately 650,000 passengers per year."

Richard Tree, PTS Transit Manager remarked:

"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. These 100% electric buses will provide a clean, quiet transit solution for our residents and business owners in Porterville."

Ryan Popple, CEO of Proterra commented:

"With California representing nearly half of the U.S. 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. We're pleased to be in a position to scale production to meet growing demand for zero emission vehicles and ultimately enable transit agencies to go electric."
