Utility rules and programs for Germantown
Pepco and Potomac Edison serve Montgomery County, so which rules apply depends on your address.
| Utility | Type | Battery and related programs |
|---|---|---|
| Potomac Electric Power Co | investor-owned | Pepco runs EmPOWER Maryland efficiency programs, but we could not confirm current rebate amounts; one listing gave a different figure from another, so ask Pepco. We found no Pepco solar or battery rebate. Pepco’s EV charger program amounts were not confirmed. |
| The Potomac Edison Company | investor-owned | Its Maryland page says it has no rebate or incentive for customer-owned generation. A bill insert lists HVAC and heat pump water heater discounts through Dec. 31, 2026 (we did not confirm amounts), and it filed a battery and EV virtual power plant pilot. |
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 Germantown
- 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.
