Solar incentives in INIncentive Description Value
Renewable Energy Property Tax Exemption
Value:Varies
Property tax exemptions apply in Indiana for solar, wind, geothermal, and hydroelectric power and thermal devices. (Solar devices installed before January 1, 2012 do not qualify for an exemption.) For most generation systems, exemptions will amount to the currently assessed value of the system (adjusted for depreciation.) Solar thermal, HVAC, or pool heating systems will be exempted at a fixed amount equal to parts and labor costs. Unique to Indiana, should the owner sell their property, exemptions will not apply to the new owner. Qualifying taxpayers may claim the exemption by filing Form 18865 with their county. Additional information is available from the Indiana Department of Local Government Finance website.
Community Conservation Challenge
Value:Varies
NOTE: This program is closed to new applicants. Indiana's Community Conservation Challenge is a grant program managed by the Office of Energy Development. Commercial, industrial, or agricultural property owners may be eligible for $20,000 - $80,000 to install new renewable energy systems or make energy efficiency improvements. Projects that may qualify for funding include green vehicles, HVAC, lighting, solar PV/thermal systems, and wind turbines. At least one community must partner with the property owner, and the completed project should be visible to the public eye. Additional information is available from the OED website.
NIPSCO - Feed-In Tariff
Value:Varies
NIPSCO pays feed-in tariffs to distributed renewable energy customers with systems rated for 3 kilowatts to one megawatt of capacity. Monthly compensation will take the form of a bill credit based on the amount of excess energy sent back to the grid. Unlike net metering, NIPSCO has greater control over how much of a customer's generated energy can be considered "excess." This control is to keep the grid stable. Customers must "opt in" to receive tariffs by filling out an application on the NIPSCO website and paying an administration fee based on system capacity; the current fee is $1 per kilowatt plus $25.
Clean Energy Portfolio Standard
Value:Varies
Indiana has adopted a non-binding renewable portfolio standard called the CHOICE. There have been three clean energy targets set with the final goal of sourcing 10% of the state's energy from renewable sources by 2025. Unique to the CHOICE standard, up to 30% of investments can be in cleaner conventional energy (natural gas, CHP, and clean coal). Participation in the CHOICE is completely voluntary. Interested utilities can register with the state's Utility Regulatory Commission to submit business and project plans. As a utility makes CHOICE investments, they will earn Clean Energy Credits pegging energy capacity to a fixed dollar value. Additional information is available from the CHOICE website.
City of Bloomington - Sustainable Development Incentives
Value:Varies
Special administrative incentives may apply to new construction in Bloomington, IN if it meets certain green building standards. The city has established standards across four areas, including energy efficiency, landscape/water efficiency, public policy (specifically promoting alternative vehicles), and public transportation. Buildings meeting certain minimum quotas for projects in the goal areas may qualify for permit fee waivers and less strict setback requirements.

City of Indianapolis - Green Building Incentive Program
Value:Varies
Special permitting privileges may apply to new projects in Indianapolis or greater Marion County if designers adhere to certain energy efficiency standards. Qualifying structures should either use on-site solar panels/small wind equipment or be ASHRAE 90.1 certified. Appliances, lighting, and HVAC systems used should be ENERGY STAR certified. Once the builder applies for permits, the structure will be ranked across six sustainability criteria. If it passes minimum standards on at least half of the criteria, 30% of the total permit fees will be refunded. For each additional criterion, another 10% will be added to the total rebate. Additional information is available from the Indianapolis city website.
