HB 5442 Connecticut House · 2026 Regular Session

AN ACT CONCERNING THE PROPERTY TAX EXEMPTION FOR AND TAX AGREEMENTS RELATED TO CERTAIN CLASS I RENEWABLE ENERGY SOURCES.

This bill updates Connecticut's property tax exemption rules for renewable energy systems, expanding eligibility for homeowners, farms, and businesses while clarifying how exemptions are calculated. It allows property tax exemptions for residential solar, wind, and geothermal systems installed on or after October 1, 2007, and extends similar benefits to commercial and industrial renewable energy projects installed between 2010 and 2013 in specific municipalities. The legislation also establishes new exemption categories for commercial solar and wind projects installed after 2014, with additional restrictions taking effect in 2025 and 2026 that limit exemptions to the equipment itself rather than the entire property value. These changes apply to Class I renewable energy sources including solar, wind, geothermal, and hydropower facilities that generate electricity for on-site use.
