Utility rules and programs for Bethesda
Pepco serves homes in Bethesda.
| Utility | Type | Generator rules |
|---|---|---|
| Potomac Electric Power Co | investor-owned | A generator transfer switch is electrical work: use a licensed Maryland electrician and pull the electrical permit your county or city requires (we did not confirm a single statewide rule). |
Program details are from each utility’s own pages (read October 2026). See the Maryland incentives table for statewide credits and a status for every program.
What to plan for in Bethesda
- Winter weather (very 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 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.
- 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.
