Utility rules and programs for Mentor
Cleveland Electric Illum and City of Painesville serve Lake County, so which rules apply depends on your address.
| Utility | Type | Generator rules |
|---|---|---|
| Cleveland Electric Illum 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. |
| City of Painesville | city-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. |

What to plan for in Mentor
- 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.
- 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.
- River and heavy-rain flooding (relatively moderate): Heavy rain can flood basements and take out power. Put sump pumps on backup power and keep equipment above the flood line.
