What This Utility Data Tells You
MPD Electric Cooperative is a member-owned electric cooperative operating in South Carolina under EIA identifier 66073. It reports service to approximately 38,286 customer accounts and generated about $0.14 billion in annual electric revenue. 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 MPD Electric Cooperative customer experienced 258.3 minutes of power interruptions, a metric called SAIDI (System Average Interruption Duration Index). Excluding major weather events from that total, that sits within the 120–180 minute national benchmark range, indicating performance typical of U.S. distribution utilities. Over the same period, SAIFI (outage events per customer) was 2.02, putting the typical customer at roughly 2 distinct interruptions that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 127.2 minutes; the difference from the headline 258.3 shows how much of the outage total came from weather rather than everyday grid issues.
Only a single year of reliability data is available, so multi-year trend analysis is not yet possible for MPD Electric Cooperative.
