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.
| Utility | Type | Generator rules |
|---|---|---|
| Louisville Gas & Electric Co | investor-owned | A generator transfer switch is electrical work: use a Kentucky-licensed electrician, get the local electrical permit and expect inspection by your building department; we could not confirm each Kentucky utility’s rule for generators that can feed the grid. |
| Salt River Electric Coop Corp | member-owned cooperative | A generator transfer switch is electrical work: use a Kentucky-licensed electrician, get the local electrical permit and expect inspection by your building department; we could not confirm each Kentucky utility’s rule for generators that can feed the grid. |
Program details are from each utility’s own pages (read October 2026). See the Kentucky incentives table for statewide credits and a status for every program.
What to plan for in Jeffersontown
- Tornadoes (very high): Tornado-season storms cut power quickly. A battery that switches on by itself, or a portable generator ready to go, covers the first night; sirens and weather radios need power too.
- River and heavy-rain flooding (relatively high): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
- Heat waves (relatively high): Heat waves strain the grid just when air conditioning matters most. Decide what must stay cool, such as one room, medicine and the fridge, and size backup to that rather than the whole house.
