Modifies provisions of the "Property Assessment Clean Energy Act"

HB 2119 modifies Missouri's "Property Assessment Clean Energy Act" to establish a program financing energy efficiency and renewable energy improvements for non-residential properties. It creates "clean energy development boards" (formed by municipalities) that can offer long-term property assessments (up to 30 years) to fund projects like solar installations or building retrofits, with these assessments recorded as liens on the property. The bill excludes residential properties, requires annual reporting to municipalities and the Department of Natural Resources, and defines key terms like "energy efficiency improvement" (e.g., insulation, efficient lighting) and "renewable energy improvement" (e.g., solar, wind systems). These boards gain authority to issue bonds, collect fees, and administer the financing program under state oversight.
