Decarbonize NY - Paying for Decarbonization: A Guide to the Financing, Incentives and Tax Benefits Available to New York City Building Owners




Tuesday, November 10, 2026
News, thoughts and tools to guide property owners and managers, lenders, developers and
sustainability professionals in their pursuit of a greener New York.


Local Law 97's 2030 limits will require most covered buildings to electrify heating or hot water, tighten the building envelope, or both, and the cost of that work is the question owners ask us most often. The answer is that a great deal of public and utility money remains available, but the programs changed substantially in 2026 and several that owners remember have closed. This article summarizes what is open now, who qualifies, and what to watch. Amounts are the programs' published figures as of October 29, 2026 and are subject to change and to the availability of funds.

What changed this year. Four developments reshaped the landscape. First, under the Public Service Commission's 2026–2030 orders, the utilities' heat-pump incentives for multifamily and commercial buildings moved out of the statewide "NYS Clean Heat" program into Con Edison's own sector programs, partial or hybrid electrification is no longer incentivized, and market-rate gas-equipment rebates were largely eliminated. Second, the federal budget act signed July 4, 2025 terminated the Section 179D deduction, the Section 45L credit and the Section 30C charging credit for projects beginning construction or placed in service after June 30, 2026, while leaving the investment tax credit for storage and geothermal largely intact. Third, Con Edison stopped accepting Level 2 EV make-ready applications in April. Fourth, on the positive side, the City enacted a new J-51 abatement equal to 100% over a multi-year period of certified rehabilitation cost, effective January 1, 2027, and the State's Standalone Clean Energy Initiative now offers regulated affordable buildings up to $37,000 per unit in grants for deep electrification.

LL97 Beneficial Electrification Credit All covered buildings Double emissions credit for heat pumps operational before 2027; half credit for 2027–2029 Equipment must be running by Dec. 31, 2026 for the double credit

Stacking. The State and City electrification grants (SCEI, CEI, HPD REDi) and Con Edison's affordable multifamily electrification incentive each exclude one another for the same measures, so an affordable building generally chooses one. NY-Sun, Charge Ready NY, FlexTech, C-PACE and the tax benefits can usually be layered on top. The solar abatement is unavailable to properties receiving ICAP, 421-a or PILOT benefits, which is a trade-off to consider for commercial owners.

Closed or ended. The Climate Friendly Homes Fund, NYSERDA's Low Carbon Pathways and Multifamily Performance programs, HPD's Green Housing Preservation Program, HUD's Green and Resilient Retrofit Program and Con Edison's PowerReady Level 2 program are no longer accepting applications, and the federal 179D, 45L and 30C benefits are unavailable for new work. Owners who budgeted around any of these should revisit the numbers.

Timing. Several deadlines fall within weeks: Con Edison's 2026 incentive rates expire with the 2027 program manuals due December 15; National Grid's 2026 weatherization applications are due December 31; and the Local Law 97 double electrification credit requires heat pumps to be operational by December 31.

On the Horizon

Upcoming Deadline – Coordinate the No. 4 Oil Phaseout With LL97 Planning – NYC Administrative Code §24-168 prohibits boilers serving private buildings from burning No. 4 fuel oil on or after July 1, 2027. Owners subject to LL97’s annual emissions limits should evaluate the required conversion alongside their preparations for the tighter 2030 caps and keep in mind that converting away from No. 4 oil does not automatically satisfy LL97.

Compliance Reminder – LL84 Penalties Continue After the Annual Deadline – Owners who have not completed their 2026 Local Law 84 benchmarking submission, covering 2025 consumption, should file promptly. DOB may assess $500 penalties quarterly, up to $2,000 per reporting year; the next assessment is February 1, 2027. Owners should confirm that the City has received a fully compliant submission and resolve any outstanding reporting errors. Completing the overdue filing can prevent further quarterly penalties, although previously incurred penalties may remain payable.

Items to Watch – Steam Decarbonization Collaborative Begins November 12 – In an October 20 notice, the New York State Department of Public Service announced the first meeting of a collaborative examining decarbonization of Con Edison’s steam system. Scheduled for November 12, 2026, the collaborative is intended to evaluate emissions calculations, potential technologies and implementation timelines. Steam purchased contributes to a building’s LL97 reported emissions. Owners evaluating whether to retain steam service or electrify building systems should follow the collaborative’s work while continuing to model compliance using DOB’s prescribed emissions coefficients. Interested stakeholders can request meeting access through the contact identified in the notice.

Compliance Planning – Recheck the Emissions Limit for Your 2027 LL97 Report – The temporary option to use the original Building Code occupancy-group limits applies only to calendar years 2024 and 2025. Under DOB’s LL97 rules, 2026 emissions, reported in 2027, must be assessed using ENERGY STAR Portfolio Manager property types. Owners who relied on the temporary option should have their Registered Design Professional recalculate the applicable limit instead of assuming that prior compliance will carry forward.
