Utility rules and programs for Westminster
BGE and Potomac Edison serve Carroll County, so which rules apply depends on your address.
| Utility | Type | Battery and related programs |
|---|---|---|
| Baltimore Gas & Electric Co | investor-owned | Home Performance with ENERGY STAR rebates: up to $10,000 or 75 percent of project cost, or up to $15,000 with a heat pump fuel switch, and $100 per smart thermostat. BGE has a two-year virtual power plant pilot for batteries and EVs before the PSC (Case 9761); we could not confirm sign-up terms. We found no BGE solar or battery purchase rebate. |
| 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 Westminster
- 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.
- 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.
- Lightning (relatively moderate): Lightning causes short outages and damages electronics. Surge protection and a battery that switches over automatically protect the things you care about.
