Baltimore Gas & Electric Co
Average price is revenue divided by sales for the sector and year; it is not a tariff rate. Reliability figures are as reported by utilities to EIA on Form 861 and may use different calculation methods. Annual figures: Form EIA-861 for 2024, final release. Monthly state figures run to July 2026.
Baltimore Gas & Electric Co is an investor-owned utility that reported 1,214,100 residential customers in Maryland on Form EIA-861 for 2024, with a service territory that touches 9 counties.
Its average residential price that year was 17.91¢ per kilowatthour, about the same as the Maryland average of 17.86¢ and 8.7% above the US average of 16.48¢. The figure is residential revenue divided by residential sales, so it folds in fixed charges, riders and every rate schedule the utility bills under.
That works out to an average residential bill of $155.58 a month on average use of 869 kWh a month. Across Maryland the average bill was $165.87 on 929 kWh, so a bill gap reflects how much power households use as well as what each kilowatthour costs.
The price covers the 1,025,745 residential customers on bundled service. A further 188,355 take delivery only and buy their energy from another supplier; EIA collects just part of their bill from this respondent, so they are left out of the average.
For reliability it reported a SAIDI of 133.5 minutes per customer with major event days included and 66.7 minutes with them excluded, calculated under IEEE 1366 standard. The median among Maryland utilities reporting was 106.3 minutes with major event days; this utility's figure is 26% above that median.
The average price is up 46.2% on 2019, against up 36.1% for Maryland as a whole, and up 8.7% on 2023. EIA's early release for 2025, which has not been fully edited, shows 20.19¢.

Customers, sales and revenue count every service type the utility reported (bundled, energy-only and delivery-only). The price column uses bundled service alone, because part-bill revenue would understate it. Sources of energy: 15.4 TWh in total, of which 0% was its own net generation and 15.4 TWh was bought wholesale; summer peak demand 6,766 MW.
Reliability
Minutes of sustained interruption per customer in 2024, as the utility reported them under IEEE 1366 standard. SAIFI: 0.80 interruptions per customer with major event days, 0.63 without; CAIDI 167.9 minutes per interruption. EIA's Maryland total across all reporting utilities was 118.1 minutes with major event days and 75.1 without. Major event days are storms and similar events that a utility's chosen method sets apart; methods differ, so treat comparisons as approximate. What SAIDI and SAIFI mean.
