National Grid Heat Pump Incentives: The 2026 Western New York Guide

If your electric bill says National Grid and your address says Buffalo, Tonawanda, Amherst NY, Cheektowaga, or West Seneca, you are standing in front of one of the stronger heat pump incentive setups in the country. You just need to know whose money it is, how it is counted in 2026, and the one rule that determines whether you ever see a dollar of it.

This guide covers all three.

Whose Money It Is: National Grid as Administrator

The headline program is NYS Clean Heat, New York State's heat pump incentive. National Grid does not invent the program; it administers it. NYS Clean Heat is delivered through six utility administrators statewide, and National Grid is the one that matters for nearly every Western New York address.

The distinction earns two sentences of your attention because it changes where you verify things. The money is state-funded and the rules are statewide, so cleanheat.ny.gov and nyserda.ny.gov are the source of truth, and National Grid is the channel it flows through, with the administrator's version at nationalgridus.com. This is emphatically not the dead federal HEAR program wearing a new logo; HEAR is gone, and NYS Clean Heat is New York's own funding, alive and paying in 2026.

The shape of the incentive through National Grid:

What Changed in 2026: Flat Per-Project Incentives

Here is the piece of news most Western New York homeowners have not caught up with. National Grid NY moved to flat per-project incentives in 2026, replacing the prior per-Btuh, per-ton model.

Under the old counting, the incentive scaled with system capacity: bigger tonnage, bigger check, with all the quiet pressure toward oversizing that implies. Under the 2026 flat model, the incentive is set per project, bounded by the same two guardrails as the rest of the program: the $12,000 household cap and the 70 percent cost cap (85 percent enhanced).

Two practical consequences follow.

Old quotes are stale quotes. If you collected a National Grid territory quote in a prior year and its incentive line was built from tons or Btuh, that math is dead. Have any carried-over quote re-run under the 2026 flat structure before you compare it to anything current.

The oversizing temptation is gone. With no per-ton reward, there is no program incentive to pad capacity. That aligns the program with good engineering, which in Buffalo means a system sized by a real load calculation to the 2F design temperature, a subject our cold-weather equipment guide treats in full.

The Rule That Decides Everything: Participating Contractors

The incentive is typically assigned to and applied by a NYS Clean Heat participating contractor as a project discount. Read that twice, because it is the entire game.

You do not file for this money yourself. You do not front the cash and chase a rebate check through the mail. And, critically, you cannot claim it at all through a contractor who is not enrolled as a NYS Clean Heat participating contractor. The participating contractor applies the discount to your invoice, files the paperwork, and the state's money shows up as a smaller number on the bottom line before you pay it.

So the first sorting question for any Buffalo bidder is not price. It is: are you a NYS Clean Heat participating contractor? A no, however friendly, means the $12,000 does not exist for your project through that bidder. Our guide to choosing a Buffalo HVAC contractor builds the full vetting checklist on top of this first gate.

Stacking: What Combines and What Does Not

The 2026 stacking rules are mercifully short.

EmPower+ is a tier, not a topper. Income-eligible households qualify for the enhanced tier: up to $24,000 at an 85 percent cost cap. It replaces the standard tier on the same measure; you get one or the other, and for a qualifying household the enhanced tier is dramatically better. Screen for it before you size a system, because it can change what is worth building.

Geothermal rides its own rail. Ground-source systems carry a separate, higher incentive. If you are weighing air-source against geothermal, compare complete net-price scenarios, not the incentive lines alone.

There is no federal layer. The 25C and 25D federal credits ended December 31, 2025, and DOE HEAR is dead, so nothing federal stacks on a 2026 installation. Any stack math that still includes a federal line is out of date. State money through NYS Clean Heat is the whole stack, and it is enough to move real projects, as the worked examples in our Buffalo rebates guide show in dollar-by-dollar detail.

A Worked National Grid Example

An illustrative North Buffalo double (a 2-unit building qualifies under the 1-4 unit rule), converting to a qualified-list cold-climate system:

The caps interact exactly as designed: on this illustrative project the 70 percent cost cap binds a hair before the $12,000 household cap does, so the smaller number governs the discount. A slightly larger project would flip which limit binds. Either way, the participating contractor applies the figure to the invoice and the owner pays the net.

If that same household were income-eligible under EmPower+, the project would carry 85 percent, or $14,025, and net out at $2,475.

Your Five-Minute Action Plan

1. Pull your electric bill and confirm National Grid, near-certain across Buffalo and the first-ring towns.
2. Read the program source directly if you like: cleanheat.ny.gov, nyserda.ny.gov, and nationalgridus.com.
3. Collect two or three quotes, exclusively from NYS Clean Heat participating contractors.
4. Require 2026 flat-structure incentive math as a line item on every quote: gross, discount, net.
5. Screen for EmPower+ before you pick a system size; the enhanced tier can rewrite the project.
