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.

src-f4b6c53620ea1346Primary MTA document. Carries the 2018 commitment wording ('In 2018, the MTA announced a commitment to transition the entire bus fleet to zero-emissions by 2040'), the fleet size of almost 6,000 buses, the four transition stages including 560 battery-electric buses in Stage 1, the ~262 MW of new power supply across 28 bus depots, and the agency-wide 85% GHG reduction goal.
src-cfa951c7f87b8d77Reports the MTA's own figures presented to the board: 60 New Flyer electric buses in service, 2,111 miles between major repairs against 13,000 for diesel, 60% versus 91% full-day availability, and the named failure modes (battery overheating, electrical components affecting air brakes).
src-961ad4dc31015c2fCarries the scale-back: order cut from 380 to 295 forty-foot electric buses, 85 diesel-electric hybrids substituted, deliveries moved to April–December 2028, the 2,500 versus 8,500 mile failure gap, and the Lazarus quote about setting a performance framework before going all in.
src-8e646cf242ce4732Documents the pause of the 205-bus and 265-bus deliveries, the state of depot charging (seven depots operational or on pace by 2027, four more planned) and the shrinking supplier market after Nova Bus left the US in 2025.
src-deb4ae158e2b68bbMTA's own wording for the 265-bus purchase, the 60 zero-emission buses already delivered and 205 slated to follow, the congestion-pricing funding, and the Jamaica depot automated overhead pantographs expected in autumn 2027 plus pantograph work at Gun Hill and Queens Village.
src-a50d6f0caa2baec2Manufacturer confirmation of the order composition — 193 forty-foot and 72 sixty-foot Xcelsior CHARGE NG buses as an option order on the contract signed in Q1 2024, building on a firm order of 205. No contract value is disclosed, which is why this entry carries no cost figure.
src-d38dca083f581a38The bill that would have required every public transportation system receiving state operating assistance to purchase only zero-emission buses from 1 January 2029. Status: stricken, last action 6 May 2024 — the evidence that the 2040 target rests on an MTA commitment, not on statute.
src-b75e74837d5570d5Source for the Lazarus quote that the electric buses are 'in service about 30 or 40 percent less than our diesel buses', and for the comparison that the New Flyer battery buses broke down more than three times as often as their diesel counterparts.
src-6a4f797683cfcea2Independent federal write-up of the Kingsbridge depot modelling study: 5,800 MTA buses carrying more than 2.1 million weekday riders, and behind-the-meter storage and solar modelled at more than 35% annual utility cost savings (about $2.08 million a year). Used here only as context for the depot-power problem.
