The Metropolitan Transportation Authority — a New York State authority, not a city agency — committed in 2018 to converting its fleet of almost 6,000 buses, operated by MTA New York City Transit and the MTA Bus Company, to zero emissions by 2040. Stage 1 was meant to put 560 battery-electric buses on the road; by mid-2025 only 60 New Flyer buses were actually in service, and the MTA's own reporting to its board put them at 2,111 miles between major failures against 13,000 miles for diesel buses, available for a full day of service 60% of the time against 91%. Deliveries of the next 205 and 265 buses were paused in 2026, and in July 2026 the authority cut a 380-bus order to 295 and substituted 85 diesel-electric hybrids. The charging side is the harder half: the transition plan calls for roughly 262 MW of new power supply across 28 bus depots, with automated overhead pantographs due at the Jamaica depot in autumn 2027. No state law requires any of this — a bill mandating zero-emission-only bus purchases from 2029 was stricken in the New York Senate in May 2024.
📊 Impact
MTA figures reported to its board in June 2025: battery-electric buses averaged 2,111 miles between major failures against 13,000 miles for diesel buses, and were available for a full day of service 60% of the time against 91% for diesel. A year later the reported gap was 2,500 miles against 8,500. MTA rolling-stock procurement head Jessie Lazarus described the electric buses as "in service about 30 or 40 percent less than our diesel buses". In July 2026 the MTA reduced a 380-bus order to 295 and replaced the 85 cancelled battery-electric buses with diesel-electric hybrids, with the remaining deliveries pushed to April–December 2028.
🎓 Lesson
The retreat was possible because the operator publishes the metric that condemned it: mean distance between failures and availability are standing MTA performance measures, so a 60-bus electric fleet could not quietly be reported as equivalent to the diesel fleet it was meant to replace. The MTA's own conclusion, in Lazarus's words, was that "we must set some framework for evaluating the performance of propulsion before we go all in" — agree the acceptance test before the order, not after it. The second lesson is that the vehicles are the cheap half: about 262 MW of new depot power across 28 depots is a utility project, not a procurement.
