What This Utility Data Tells You

The Narragansett Electric Co is an investor-owned utility operating in Rhode Island under EIA identifier 13214. It reports service to approximately 404,034 customer accounts and generated about $0.83 billion in annual electric revenue, with a service footprint spanning 89 ZIP codes. As an investor-owned utility, it operates under state public utility commission oversight that reviews rate cases and reliability performance.

In 2023, the average The Narragansett Electric Co customer experienced 104.6 minutes of power interruptions, the industry-standard SAIDI metric (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. The SAIFI figure, which tracks average outage events per customer, came in at 0.78 for the same period, meaning customers statistically saw about 1 distinct interruption that year. Strip out major event days (hurricanes, ice storms) and SAIDI falls to 52.2 minutes; the difference from the headline 104.6 shows how much of the outage total came from weather rather than everyday grid issues.

With 4 consecutive years of EIA data (2020–2023), The Narragansett Electric Co's reliability record can be judged on trend rather than one isolated year. SAIDI dropped from 548.4 to 104.6 minutes across that span, a direction regulators and prospective customers tend to watch closely. Note: this figure is unusually low compared to typical U.S. utility performance and may reflect an incomplete EIA filing for this year rather than a genuine reliability improvement -- treat with caution and cross-check against The Narragansett Electric Co's other reported years.
