Colorado Governor Bill Ritter (D) recently signed into law a bill (S.B. 10-177) creating a property tax incentive to promote biomass energy development. The new law, effective August 11, 2010, defines a biomass energy facility as one where energy is produced from the combustion of “only biomass or biosolids derived from the treatment of wastewater.” The facility must also be designed to supply electricity for off-site consumption and must have begun energy production after January 1, 2010. For property tax purposes, such facilities will be valued based on their projected gross revenue, the same manner in which wind and solar facilities are valued under state law.
