Sachem board hears NYSERDA-funded study on converting buses to zero-emission, flags costs and operational limits

Consultants from Wendell presented a NYSERDA-funded fleet-electrification study to the Sachem Central School District Board of Education on Feb. 4, saying the district's 40 owned buses and contracted routes are technically capable of operating as zero-emission vehicles but that upfront infrastructure and vehicle costs would be substantial.

"There is a mandate from New York State, is mandating the transition to 0 emission vehicles," Adam Kaufman, project manager at Wendell, told the board, describing two key deadline windows: new bus purchases must be zero-emission beginning in 2027 (subject to limited waivers) and the state aims for full fleet conversion by 2035. Kaufman said NYSERDA paid for the study and that, for Sachem's owned-and-operated fleet, Wendell estimated a site charging capacity need of roughly 320 KVA and noted PSEG hosting-capacity maps show local availability of about 0.65 megawatts at the site.

Why it matters: the state program includes purchase and charger incentives that can significantly reduce near-term costs but do not eliminate major infrastructure spending. Kaufman said Sachem qualified as a priority district and could receive incentives covering up to 14 buses and sizable charger vouchers; PSEG and state incentive programs could also contribute to utility- and customer-side infrastructure costs.

Board members focused questions on warranty and lifecycle costs, safety and operational limits. Kaufman said battery warranties are commonly eight years and that manufacturers and districts report 10'12 years of service in some cases; he cautioned the study used conservative winter-case modeling and an 11% safety factor to account for degradation and route changes. "There's an estimated degradation over the life cycle of the battery of about 10%," Kaufman said when describing modeling assumptions.

Several trustees pressed how the district would handle long-distance or multi-leg trips. Kaufman said a conservative operational limit in stressed winter conditions was roughly 65 miles per duty cycle and that some long trips may require contracting coach services if electric buses cannot make the round-trip and charging schedule.

Trustees also raised safety and insurance concerns after presentations about battery-fire response and required fire-protection measures for electric buses. Kaufman said codes and fire-protection approaches are evolving and that districts should involve fire marshals and insurers early in planning; one trustee urged staff to get specific insurance-cost estimates because those expenses are not covered by state aid.

What the board will do next: administration and the consultants recommended a phased, "one bite at a time" approach: pilot a small number of electric buses to learn about charging infrastructure, driver training and charge-management systems while pursuing available incentive funding and state waivers where warranted. The board did not take formal action; members directed staff to continue evaluating costs, potential waivers for long-route exceptions and advocacy through the legislative committee.
