Tennessee — Amendments Regarding the Valuation of Green Energy Source Property

Blog, ONESOURCE, ONESOURCE Property Tax May 10, 2013

Changes have been made to legislation regarding green energy source property valuation, effective 4/29/13:


  • The maximum wind source property value cannot initially exceed one-third of total assessed costs.
  • The maximum solar source property value cannot initially exceed 12.5% of total installed costs.
  • Other green source property’s maximum value cannot initially exceed its appropriate capacity factor.


The assessor must take the above findings into account when determining the value of green source property at the initial appraisal and at each reappraisal. The comptroller must let the assessor know of locations of locally or centrally assessed certified or other green energy property on or before the scheduled reappraisal in each county.
