Utility rules and programs for Bloomington
Duke Energy Indiana and South Central Indiana REMC serve Monroe County, so which rules apply depends on your address.
| Utility | Type | Generator rules |
|---|---|---|
| Duke Energy Indiana, LLC | investor-owned | A generator transfer switch is electrical work: Indiana has no statewide electrician license that we found, so use a locally licensed or registered electrician, get any local permit and expect inspection by your building department (not confirmed); I&M says a backup generator used only during outages needs no utility approval. |
| South Central Indiana REMC | member-owned cooperative | A generator transfer switch is electrical work: Indiana has no statewide electrician license that we found, so use a locally licensed or registered electrician, get any local permit and expect inspection by your building department (not confirmed); I&M says a backup generator used only during outages needs no utility approval. |
Program details are from each utility’s own pages (read October 2026). See the Indiana incentives table for statewide credits and a status for every program.
What to plan for in Bloomington
- Strong winds (relatively high): High winds knock out lines on ordinary days. A battery or portable power station handles the common short outages; add a generator for multi-day repairs.
- Winter weather (relatively high): Winter storms and cold snaps combine outages with heating demand. Plan for the furnace blower or heat pump, not just lights, and keep a fuel supply you can reach in snow.
- Heat waves (relatively moderate): 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.
