How to choose a generator or battery installer in Indiana
Licensed electrician for the transfer switch (NEC 702)
A standby generator or home battery is connected through a transfer switch or backup gateway that must isolate your home from the utility so the system can never backfeed the grid (NEC Article 702 for optional standby systems, Article 706 for stationary batteries). That is licensed electrical work in Indiana; a dealer that subcontracts it should name the electrician on the quote.
Gas line, pad placement, and the mechanical permit
A natural-gas or propane generator needs a licensed gas fitter to size and run the fuel line, and the unit must sit on a level pad at the clearance the manufacturer and your local code require from windows, doors, and vents because of carbon-monoxide risk. Expect an electrical permit and, in most jurisdictions, a mechanical or gas permit, each with an inspection.
Size to your real outage loads, then compare quotes
Ask every installer for a load list: which circuits get backed up (furnace blower, well pump, fridge, sump pump, central air) and their starting watts. Compare quotes on the same generator kW or battery kWh and kW rating, the transfer-switch type (automatic vs. manual, whole-house vs. managed circuits), the warranty, and who handles the annual service.
What to know before hiring in Indiana
The largest utilities serving Indiana homes are Duke Energy Indiana (796,265 residential customers, 12.8¢/kWh), AES Indiana (469,499 residential customers, 13.8¢/kWh) and Northern Indiana Pub Serv (430,648 residential customers, 19.1¢/kWh). Your utility sets the rate your backup power replaces, and it is also who an installer files interconnection or service paperwork with, so name it when you ask for quotes.
Check the license before you sign
Indiana licenses electrical contractors at the city or county level rather than statewide; the City of Indianapolis Department of Business and Neighborhood Services is the starting point. Indiana has no state electrical license; Indianapolis/Marion County issues Electrical Contractor licenses and other municipalities run their own.

Bridge the gap before the install
A standby generator or home battery takes weeks from quote to inspection. A portable inverter generator covers the fridge, furnace blower and electronics in the meantime, and stays useful as a backup to the backup. Size it with the generator sizing calculator, and run it outdoors, well away from doors and windows.
