Baltimore Gas & Electric Co

What This Utility Data Tells You

Baltimore Gas & Electric Co is an investor-owned utility operating in Maryland under EIA identifier 1167. It reports service to approximately 1,081,061 customer accounts and generated about $2.12 billion in annual electric revenue, with a service footprint spanning 225 ZIP codes. Investor ownership puts this utility under the regulatory authority of the state public utility commission, which reviews its rate requests and reliability record.

In 2023, the average Baltimore Gas & Electric Co customer experienced 191.0 minutes of power interruptions, a measure known as SAIDI, or System Average Interruption Duration Index. Excluding major weather events from that total, that is comfortably under the 120–180 minute national benchmark range, a sign of solid grid resilience and quick outage response. Over the same period, SAIFI (outage events per customer) was 0.96, putting the typical customer at roughly 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 60.4 minutes, the gap between that figure and the headline 191.0 reveals how much weather, not day-to-day infrastructure, drove outages.

With 4 consecutive years of EIA data (2020–2023), Baltimore Gas & Electric Co's reliability record can be judged on trend rather than one isolated year. SAIDI climbed from 117.7 to 191.0 minutes over that window, a shift that can point to worsening weather exposure or delayed grid modernization.
