Energy Incentives in 2026: What Changed and What to Check Before You Commit

Incentive stacks for commercial and industrial projects look different than they did a year ago. Three things to check before you commit capital.

Federal credits depend on the technology and the dates

Under Treasury Notice 2025-42, a wind or solar project that begins construction after July 4, 2026 must be placed in service by December 31, 2027 to keep its federal credit. Storage follows a longer schedule, but foreign-content rules now apply to it, and a project whose components cannot be documented can lose eligibility. Our post on solar and storage tax credits after July 2026 covers the dates and the material-assistance test.

State and utility programs run on their own funding

Programs such as California's Self-Generation Incentive Program operate in funding steps, and incentive levels and availability change as steps fill. Confirm the current step and your utility's availability with the program administrator before you build a model around it.

Local financing is local

PACE financing, municipal grants and utility demand response programs exist in many regions, but eligibility, terms and timing differ by jurisdiction.

What to do before you spend

Model the project against your own load profile and current tariff, with the incentive dates and component rules checked. We do not publish a headline incentive number, because the figure is specific to the site.
