Solar incentives in KYIncentive Description Value
Tax Exemption for Large-Scale Renewable Energy Projects
Value:Varies
Beginning in 2007, companies operating in Kentucky may be entitled to corporate sales or income tax exemptions on new energy efficiency or renewable energy investments. A complete sales tax exemption may apply to any materials or equipment a company uses to make improvements. Certain employees whose jobs were created as part of the improvements may write off a 4% wage assessment on their own income taxes. A minimum investment of $1 million is required. New solar facilities should be rated for at least 50 KW, while systems using other renewable technology should be rated for at least 1 MW. Additional information is available from the Think Kentucky website.
On-Farm Energy Efficiency Grant Program
Value:Varies
The Office of Agricultural Policy, a unit of the office of the Kentucky governor, oversees the County Agricultural Investment Program (CAIP). Farmers may be eligible for program grants to fund energy efficiency improvements. Eligible projects for grant funding include new implements, insulation/weatherization, lighting, HVAC, windows, roofing, and smart thermostats. New solar thermal/PV systems and wind turbines may also be eligible. Equipment and building materials must meet certain state efficiency standards. Interested farmers may apply at any time and will be considered for the upcoming program year. Additional information is available from the OAP website.
Net Metering
Value:Varies
Kentucky requires private electrical utilities in the Commonwealth to collect renewable energy credits through net metering arrangements with their customers. Any solar, wind, biomass, or other renewable energy system rated for under 45 kW should have a bidirectional meter equipped to measure net excess generation (NEG) sent back to the grid. Customers will be compensated at a rate set by the state utility regulator. As of 2021, the rate per kilowatt hour is 9.746 cents. Systems entering a net metering contract must comply with certain IEEE and UL standards. Utilities reserve the right to restrict NEG exports to keep the grid stable. Additional information is available from the Kentucky Public Service Commission website.
Incentives for Energy Independence
Value:Varies
Various tax incentives are available in Kentucky to encourage renewable adoption research and adoption in the Commonwealth. New renewable generation farms, such as those using solar, wind, or biomass technology, may be totally exempt from state income tax, entity tax, and sales/use tax. Employees maintaining the systems may be entitled to tax credits equal to a 4% wage assessment on employers. Exemptions or special assessments are determined on a case-by-case basis and will last for up to 25 years. Certain administrative fees payable to the Kentucky Economic Development Finance Authority may apply. Additional information is available from the Think Kentucky website.
Energy Efficiency Loans for State Government Agencies
Value:Varies
The Green Bank of Kentucky (GBKY) received seed funding from the 2009 federal stimulus package. Currently, the Bank offers revolving loans to commonwealth government agencies for sustainability projects. Agencies may select from three different loan options. In each case, repaid principal will immediately "revolve" to support subsequent borrowers. SELF loans may fund any energy efficiency improvements or renewable energy investments that will reduce consumption by 20%. Available principal ranges from $50K to a maximum of $225K. Hybrid loans offer principal from $50K to $600K. These loans require energy audits before project work begins, the cost of which may be covered by loan funds. Agencies have the burden of procuring contractors and new equipment/materials. ESPC loans are designed for comprehensive or large-scale industrial improvements. Loan principal starts at $600K with no maximum. The applicant must use a recognized Energy Service Company or Energy Savings Performance Company for the work. Additional information is available from the GBKY website.
Interconnection Standards
Value:Varies
Distributed generation and interconnection have been standardized by the Kentucky Public Service Commission since 2009. Each energy system connected to the commonwealth grid will be assigned to a numerical "level" based on rated capacity. Systems at each level must follow recognized standards such as those set by IEEE or UL. Interconnection fees and application review turnaround will depend on the system's level. Customers must carry at least minimum liability insurance coverage on their energy system, and they may be required to install disconnect switches or other safety features by their utility. However, they will own any renewable energy credits they generate and may sell them to the utility at their discretion.
