Complete guide to PSEG Long Island rebates for Oyster Bay homeowners
Oyster Bay, a North Shore community spanning 388 square miles with 305,000 residents across multiple neighborhoods, sits in PSEG Long Island's service territory. The utility offers direct rebates for heat pumps, heat pump water heaters, battery storage, EV chargers, and smart thermostats. There is no residential solar rebate in PSEG territory, but federal tax credits and other financing options remain available.
This page covers verified 2026 rebate amounts from PSEG Long Island's official website. All figures are current as of August 2026, but utility rebate programs change — verify with PSEG directly before committing to a project.
PSEG Long Island's rebate tier depends on your household income. Most Oyster Bay households qualify for the higher tier ($7,500). Installed cost typically runs $13,000–$22,000, making the rebate a meaningful fraction of the project. A modern heat pump also handles cooling and typically reduces annual heating/cooling costs by 20–30%.
A heat pump water heater costs roughly $4,000–$6,000 installed and reduces water heating energy use by 50% or more. Combined with a whole-home heat pump, this is one of the highest-impact, lowest-hassle upgrades a household can make.
PSEG offers $200 per kWh through NYSERDA. A typical residential battery (13.5 kWh) costs $12,000–$15,000 installed and provides backup during outages, increasingly valuable on Long Island's aging grid.
PSEG Long Island does not currently offer a direct residential solar rebate. A typical 6 kW system costs $15,000–$18,000 and saves around $1,200 per year in electricity bills, paying back in roughly 13 years. The federal solar Investment Tax Credit (ITC) expired on December 31, 2025.
PSEG offers tiered rebates based on charger speed and efficiency. A Level 2 charger costs $500–$2,000 installed and cuts charging time from 24+ hours to 6–8 hours overnight.
A smart thermostat enables fine-grained temperature control and typically saves 1–2% on heating/cooling costs. Rebate amounts vary slightly by model; check PSEG's current list for your preferred device.
PSEG may offer insulation rebates, but we haven't yet found verified 2026 amounts. Many utilities in the Northeast offer attic, wall, and basement insulation incentives; contact PSEG directly to ask about current programs.
Window replacement is common in older Long Island homes, but we haven't verified a current PSEG window rebate. Check directly with PSEG or explore NYS Clean Energy financing options that may apply to Oyster Bay.
Starting situation: 1970s Colonial with gas heating, central air conditioning, electric water heater. Annual energy bill: ~$2,400.
Retrofit plan: Heat pump ($18K installed) + heat pump water heater ($5K installed).
Rebates: $7,500 (heat pump) + $1,200 (water heater) = $8,700 total.
Out-of-pocket: $23,000 − $8,700 = $14,300 (before any financing).
Annual savings: ~$1,500 (45% reduction in energy consumption).
Payback period: ~9.5 years; system lifespan 20+ years.
PSEG Long Island isn't a Clean Heat sponsor — it runs its own separate heating and cooling rebate program, so the amount is a flat, income-tiered figure per home rather than scaled by system size.

Oyster Bay is served by PSEG Long Island, which also covers Brookhaven, Islip, Babylon, Huntington, Smithtown, and Southampton. All six municipalities share the same rebate schedule. PSEG Long Island's rates are among the highest in the Northeast at roughly 21–23¢ per kWh, making electrification (heat pump + water heater) one of the fastest ways to reduce household energy costs.
If you rent or live in a condo, most of these rebates apply only to the building owner or management company. Tenants can pursue smart thermostat or EV charger rebates (if permitted by the lease), but major retrofits require landlord/board approval. If your building is interested in a whole-building heat pump conversion or new heat pump water heater, PSEG may offer larger rebates for multi-unit properties — contact PSEG directly.
We don't have a verified local PSEG installer directory yet. Browse our general installer directory and get multiple quotes (3–5 contractors minimum) before committing. Look for contractors with 5+ years of heat pump experience in the Northeast, clear warranties (10+ years on major components), and references from similar-age homes in your area.
1. Get a home energy audit. A professional audit ($200–$400, sometimes free through utility programs) identifies where your home loses energy and prioritizes retrofits by impact. Many Oyster Bay homes built before 1980 have significant air-leakage and insulation gaps.
2. Gather multiple quotes. Call 3–5 local contractors and ask specifically about PSEG rebates. Most will handle the rebate application, but confirm this upfront.
3. Verify current PSEG rebate amounts. Visit www.psegliny.com or call 1-800-752-6633 to confirm 2026 rebate levels and income thresholds before finalizing your budget.
4. Explore financing. If upfront cost is a barrier, PSEG offers financing options; some states also offer low-interest Property Assessed Clean Energy (PACE) loans for energy upgrades.

Every Friday: what I'm learning about rebates across every province and state we cover, heat pump reality checks, solar economics, and the installers I trust. Real stuff, no marketing.
Rebates cover the upfront cost, but the number that decides whether this is worth it is the payback period — how long until the monthly savings pay back what you spent out of pocket. Here's the real math using PSEG Long Island's actual current electricity rate:
A modern cold-climate heat pump typically moves 2.5–3.5 units of heat per unit of electricity it uses (its "coefficient of performance"), which is why it beats electric resistance heating on cost even at the same per-kWh rate. PSEG Long Island is electric-only in most of its territory; Long Island gas customers are typically National Grid, a separate bill. We didn't find a reliable current per-therm gas rate for PSEG Long Island territory to compare against — rather than guess, we're leaving gas-furnace payback math out until we can source it properly.
