Battery storage · MD
Home batteries in Maryland.
Maryland has no statewide home-battery rebate on the Connecticut model. Some utilities pay to dispatch batteries on peak days. We model that after interconnection, not before.

What makes Maryland different.
Typical homes here see about $0.22 / kWh and 1,320 kWh per kW per year. We size the system to your bill — then confirm it on the roof.
So a battery here earns its keep on three things: keeping the house up in an outage, shifting cheap daytime power into expensive evenings, and whatever demand-response your particular feeder supports. We confirm the third after interconnection rather than promising it beforehand.

Maryland, specifically
What power has actually cost here.
Every savings figure on this site assumes your utility keeps raising its rate. So does every other company’s. The difference is that you can check ours — these are the federal government’s own published prices for Maryland, next to the number we model.
| Last 5 years (2019–2024) | 6.4% |
|---|---|
| Last 10 years (2014–2024) | 2.7% |
| Since 2005 (2005–2024) | 4.0% |
| What Helio assumes | 4.0% |
No single window is the truth, which is exactly why anyone showing you one number for the next twenty-five years — including us — is showing you an assumption. Ask any installer what your savings look like at today’s rate with no increase at all. How the money works runs that comparison.
Who you buy power from here
BGE, Pepco, Delmarva, Potomac Edison. Which one serves your address decides the tariff you can take and the credit you get for what the roof exports, so an advisor confirms it before anything is filed.
Who does the work
Crews dispatch from Baltimore. Licensed in Maryland as 156798 — public record, worth looking up before you let anyone on your roof.
