How much you get
Long Island is explicitly excluded from NYSERDA's statewide Residential ISI storage block — PSEG Long Island runs its own separate battery storage incentive instead.

Administered by: PSEG Long Island (own storage program, not NYSERDA ISI)
Southampton-specific note
Southampton's own "Sustainable Grants and Rebates" town page doesn't host a town-funded program — it simply redirects residents to NYSERDA NY-Sun. There's no local top-up beyond the PSEG/state programs above.
