City and County of Honolulu - Real Property Tax Exemption for Renewable Energy Property

In September 2009, the Honolulu City Council unanimously passed Bill 58 to create a real property tax exemption for alternative energy improvements. This bill became effective October 1, 2009. Honolulu later amended it. 

The renewable energy property installed on a building, property, or land is exempt from real property taxes. Additionally, the portions of land actually used for the active production or storage of renewable energy is exempt from 80% of its value for tax purposes if the energy is primarily for use, distribution, or sale to public utilities or for public consumption under a power purchase agreement or power purchase contract with the utility.  The claim for exemption, once allowed, will continue for the period of the power purchase agreements or contract with the utility.
