California Cities Order More Proterra Electric Buses

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.”

I wish they would make fully electric RV’s in that RV’s are known to only get nine to five miles a gallon in gas.

Another thing is that when you replace a oil powered bus you are taking three to four gas powered cars off of the road due to the low gas miles buses get. And in a lot of cases a school and transit system’s operating budget can get trashed if there is a sudden rise in gas prices by a few cents.

I like Proterra although their buses are quite expensive but hopefully as the company develops they will be able to find ways to save cost.

One way to do that is mass production 😛 Producing one bus a week isn’t really going to cut it when trying to compete against the big electric bus makers.

Glad to see an electric bus that is not made in China.

FYI the company in China making electric buses, is making them in the US, in California.

We need to see electric refuse trucks. Like buses garbage trucks are a perfect fit to go electric. It’s all stop and go on set routes

We do.

I would like to see electric farm tractors. That’s a very nice fit too as it’s all about torque and the weight of the batteries are actually something positive. It would be an enormous win for the environment if we got rid of all the diesel in agriculture.

BEV vehicles do well where they have limited energy demand, as in a passenger car, or where they can be recharged frequently, as in city buses which can be recharged when they stop at bus stops.

But with battery capacity so limited, much more limited in terms of volume than gasoline, BEVs do not do well where high energy demand exists, such as driving an RV down the highway, or with farm vehicles pulling heavy loads. A BEV farm tractor would need a ridiculously expensive battery pack, and would still need to be recharged so frequently as to make it impractical.

Someday we’ll have BEV farm tractors, large RVs, 18-wheeler semi tractors, and ocean-going ships. But only after batteries improve significantly over current tech.
