Modifies provisions of the "Property Assessment Clean Energy Act"

HB 153 modifies Missouri's Property Assessment Clean Energy Act to establish new rules for property-assessed clean energy (PACE) programs. It creates definitions for key terms like "assessment contract" (a special property tax for financing energy upgrades) and "clean energy development board" (a municipal group that administers financing). The bill specifically excludes residential properties from these programs, focusing instead on commercial and industrial properties. Key mechanisms include allowing municipalities to form boards that collect annual assessments over up to 30 years to fund energy efficiency or renewable energy improvements like solar panels or insulation. These assessments become liens on the property, and boards must report annually on financed projects and collected fees.
