Southern Maryland Elec Coop Inc

What This Utility Data Tells You

Southern Maryland Elec Coop Inc is a member-owned electric cooperative operating in Maryland under EIA identifier 17637. It reports service to approximately 171,460 customer accounts and generated about $0.42 billion in annual electric revenue, with a service footprint spanning 73 ZIP codes. Being member-owned, this cooperative answers to its ratepayers rather than outside shareholders, a structure that tends to influence how rate cases and capital spending get decided.

In 2023, the average Southern Maryland Elec Coop Inc customer experienced 201.1 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). That sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. The SAIFI figure, which tracks average outage events per customer, came in at 1.33 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Excluding major event days (hurricanes, ice storms), SAIDI drops to 102.8 minutes, the gap between that figure and the headline 201.1 reveals how much weather, not day-to-day infrastructure, drove outages.

Southern Maryland Elec Coop Inc has 4 years of continuous EIA reporting on file (2020–2023), enough to read a real trend rather than a single-year snapshot. SAIDI dropped from 222.9 to 201.1 minutes across that span, a direction regulators and prospective customers tend to watch closely.
