Austin’s leftwing political class always wants to be at the forefront of any trendy ecofriendly or green initiative. That includes transitioning to an all-electric bus fleet. How well is that working out for them? According to this piece Dwight sent over, not so hot.
Capital Metro is slamming the brakes on an ambitious goal of transitioning to an all-electric bus fleet, citing problems with the range of battery-electric buses.
Austin voters were promised a transit system with exclusively electric vehicles when they authorized a tax increase in 2020 to fund Project Connect, the largest transit expansion in the city’s history. Zero-emissions buses are quieter and don’t blast hot exhaust in the faces of people on the sidewalk.
“Honestly, we thought and hoped that the technology would progress a little faster than it has,” CapMetro CEO Dottie Watkins told KUT. “The biggest downside of a battery-electric bus today is its range.”
Diesel buses can run from early in the morning until past midnight. A battery bus only runs about 8 to 10 hours before it needs to be recharged, creating tough logistical hurdles in scheduling routes.
An analysis by the Texas Transportation Institute (TTI) — a state-funded research agency at Texas A&M University — found battery-electric buses could only cover 36% of Capital Metro’s bus schedules.
“If [the route] is too long, it won’t make it,” said John Overman, a research scientist with TTI. “You’re going to have to charge them mid-route or wherever it is.” Austin’s hills drain batteries faster. So does trying to cool buses in the city’s oppressive heat.
Why rely on the opinions of experts when they’re at odds with your green fantasies?
But range shortcomings are only part of the problem.
Data obtained by KUT through the Texas Public Information Act revealed CapMetro’s battery-electric buses are far less reliable than their diesel counterparts. E-buses had mechanical failures on average every 1,623 miles over the last year — less than half the typical distance between failures for the fleet as a whole.
Mechanical problems should be an area where electrical vehicles shine, as there’s so many things that can go wrong in a diesel engine. The fact they’re less reliable is a big red flag.
Mechanical problems, coupled with challenges in procuring parts and doing repairs, mean battery-electric buses are often unavailable for service. In 2022, almost 52% of e-buses were down, on average. In 2023, the number of vehicles out for repair improved slightly to an average of just under 50%.
“Getting the expertise up and being able to have those vehicles be as reliable as our old workhorse diesel buses have been is a challenge,” Watkins said. “It’s something that we are up to.”
On top of range and reliability issues, both companies Capital Metro hired to build its battery-electric buses faced major financial challenges. Proterra and New Flyer blamed the problems on pandemic-related supply chain issues and inflation that drove up manufacturing costs after major contracts were signed.
