Utility rules and programs for Jeffersontown
Louisville Gas & Electric and Salt River Electric Coop serve Jefferson County, so which rules apply depends on your address.

|---|---|---|
| Louisville Gas & Electric Co | investor-owned | LG&E credits exported solar power at 7.089 cents per kWh as a dollar bill credit under NMS-2; older NMS-1 systems keep a kWh credit for 25 years. You apply by email to [email protected], and most applications have no fee. |

Solar Panel Installation in Jeffersontown FAQs
Is solar worth it in Jeffersontown?
The sun is strong (about 1,180 kWh a year per kW, our estimate), but export credits are low, so solar pays most when sized to what you use at home or paired with a battery. See the Kentucky incentives for the state credit.
Is there a federal solar tax credit in 2026?
No. The federal 25D credit ended for expenditures after December 31, 2025. Kentucky has no state solar tax credit or home-solar exemption that we found.
Do I need a permit for solar panels in Jeffersontown?
Usually yes, and the utility may need to approve solar and batteries. City of Jeffersontown Permitting and Enforcement handles permits in Jeffersontown; see the permit information above.
