How to Lower Your Electricity Bill in Baltimore, MD

Why Baltimore bills run high

Maryland's average residential rate is about $0.190/kWh through BGE, roughly 12% higher than the ~$0.17/kWh U.S. average. Baltimore’s classic rowhomes often have older, single-zone AC systems working against un-insulated brick walls, which makes the city a textbook case for cheap efficiency wins before spending on new equipment.

Six ways to cut your bill

1. 1
   Set your thermostat to 78°F (or higher) while home, higher while away. Every degree above 72°F saves roughly 1–3% on cooling costs. A programmable or smart thermostat that bumps the temperature up automatically while you're out is one of the highest-return, zero-cost changes you can make.
2. 2
   Seal air leaks around doors, windows, and outlets. Gaps around old windows and exterior doors let cooled air escape and hot air in, forcing your AC to run longer to hold the same temperature. Weatherstripping and caulk cost a few dollars and typically pay for themselves within a month.
3. 3
   Run major appliances during off-peak hours. If your utility bills time-of-use rates, running the dishwasher, laundry, and EV charging overnight or early morning — instead of during the late-afternoon peak — can meaningfully cut the effective rate you pay per kWh.
4. 4
   Unplug or switch off always-on electronics. Game consoles, TVs, chargers, and other devices left plugged in continue drawing small amounts of power around the clock. A power strip you can switch off at night eliminates this "phantom load" for the whole cluster at once.
5. 5
   Get your AC system serviced before peak summer. A dirty filter or low refrigerant charge can force a central AC system to work 10–15% harder to deliver the same cooling. A $100–150 tune-up often pays for itself within a single summer.
6. 6
   Generate some of your own electricity with plug-in solar. Maryland's HB 1532 now allows a permit-free, no-utility-approval plug-in solar system up to 1200W — a panel that plugs directly into a standard outlet and offsets your usage in real time. An 800W system in Baltimore generates roughly 874 kWh a year, worth about $166 at local rates.

What plug-in solar actually looks like in Maryland

Under HB 1532, Maryland now allows systems up to 1200W to plug directly into a standard household outlet — no permit, no electrician, no utility interconnection application. The law is in effect now, so a system installed today can start offsetting your bill immediately.

Bottom line

Efficiency changes — thermostat settings, sealing leaks, shifting usage off peak hours — cost little or nothing and add up fast. Generating even a fraction of your own electricity stacks on top of those savings every month, all summer, with no ongoing cost once the system is paid for.
