From KUT News:
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.
