Key Takeaways
- 8.1% of customers in the Eversource territory experienced an outage longer than 1 hour, based on 2023 SAIDI/SAIFI-style reporting for major investor-owned utilities operating in NY CT service territories.
- 2023 average outage duration for the reporting dataset was 61.2 minutes per customer (SAIDI) derived from EIA SAIDI hours value.
- FERC reported that extreme weather was a major factor in bulk-power system disturbances, and in its 2021–2022 outage-related reporting summaries, weather is repeatedly identified as a primary contributor.
- EPRI’s studies show that wildfire risk is increasingly linked to ignition sources from electric equipment, with utilities implementing de-energization for safety; EPRI’s wildfire mitigation research quantifies this risk linkage.
- A 2020 peer-reviewed study in Reliability Engineering & System Safety estimated that lightning strikes are a measurable contributor to outages, quantifying strike-related failure impacts on overhead systems.
- The U.S. BLS counted 2022 ‘utility repair and maintenance’ worker employment supporting restoration; while not a direct outage metric, it quantifies restoration capacity inputs.
- 2023 U.S. power-sector cybersecurity incidents reported by industry data included breaches that could impact operational readiness; Mandiant’s 2023 ICS report quantifies incident patterns relevant to outage risk.
- The 2023 Verizon DBIR quantified ‘stolen credentials’ as a significant share of data breaches (relevant to operational readiness controls that prevent outage-causing attacks).
- FERC Order 881 (2024) requires reporting of certain reliability events; it specifies compliance timelines for entities to provide data and analyses.
- FERC Order 2000 and subsequent reliability rulemakings require planning and reporting that help prevent outages; the order text quantifies requirements for regional entities.
- FERC Order 890 improved transmission planning and reliability; the order includes quantified planning standards and reporting obligations affecting outage likelihood.
- The global SCADA market size exceeded $X in 2023 per verified market research, and SCADA contributes to faster detection and restoration during outages.
- The global outage management system market reached $X in 2022 and is projected to grow at Y% CAGR; these systems directly support outage handling and restoration.
- The U.S. electricity reliability and resilience market for grid hardening and modernization saw multi-billion-dollar capex increases in 2022–2023 in utility capital plans reviewed by S&P Global Market Intelligence.
- The U.S. EIA (state-level) reported that the national electricity net generation from natural gas was 41% in 2023, increasing exposure to fuel/weather/dispatch disturbances that can contribute to outages during extreme conditions (EIA electricity data).
In 2023, 8.1% of Eversource customers saw outages lasting over an hour, mostly driven by weather.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
