Utility rules and programs for Delaware
Ohio Power and Dayton Power & Light serve Delaware County, so which rules apply depends on your address.
| Utility | Type | Generator rules |
|---|---|---|
| Ohio Power Co | investor-owned | We did not confirm a statewide generator transfer-switch rule for Ohio; your local building department sets permit and inspection rules, and a transfer switch or interlock is needed so power cannot flow back onto utility lines. |
| Dayton Power & Light Co | investor-owned | We did not confirm a statewide generator transfer-switch rule for Ohio; your local building department sets permit and inspection rules, and a transfer switch or interlock is needed so power cannot flow back onto utility lines. |
Program details are from each utility’s own pages (read October 2026). See the Ohio incentives table for statewide credits and a status for every program.
What to plan for in Delaware
- 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.
- Ice storms (relatively high): Ice storms bring down lines for days. A standby generator with a transfer switch, or a battery sized for the fridge, furnace blower and well pump, matters more than a small power station.
- Hail (relatively moderate): Hail is hard on rooftop solar; ask installers about impact-rated panels and your insurer about coverage.
