With 5,300 GW of U.S. electricity generation capacity already in place as of 2023, the grid we rely on is massive, yet outages and cyber risk can still ripple through millions of customer accounts. At the same time, utilities are spending on demand-side programs and grid modernization while making faster, smarter operational decisions powered by AMI, analytics, and even AI. The contrast between how big the system is and how costly disruption can be is exactly what these utilities statistics help quantify.
Key Takeaways
- 5,300 gigawatts (GW) of U.S. electricity generation capacity was in place as of 2023, reflecting the size of the utility power supply system the grid must serve.
- 9.4 million miles (mi) of U.S. distribution lines existed in 2022, reflecting the scale of last-mile power delivery.
- $8.0 billion in U.S. utility spending on demand-side management programs in 2022 (efficiency and DR program budgets).
- $62.1 billion was the estimated annual economic cost of power outages in the U.S. (direct and indirect impacts) in a study by a major reliability research organization (value depends on outage definition).
- $22.6 billion in insurance losses was reported for U.S. weather-related catastrophes in 2023 (subset relevant to grid disruption events).
- 3.6 hours was the average U.S. customer outage duration (SAIDI) for electricity in 2022, representing typical outage time experienced per customer.
- $135 per megawatt-hour (MWh) was the estimated average value of lost load (VOLL) used in many U.S. reliability planning applications, representing the cost of involuntary outage in resource adequacy analyses.
- 4.5 million customer accounts were affected by major electricity system disruptions tied to severe weather in 2022 in U.S. utility incident summaries compiled by federal emergency management data.
- $2.2 billion in reported U.S. utility cyber incidents (attempts/validated incidents) occurred in 2023 in the energy sector, per incident accounting compiled by a major risk intelligence provider.
- 68% of energy sector organizations reported at least one successful phishing attempt in 2023 in a global survey of cyber incidents affecting critical infrastructure.
- 35% of U.S. utilities prioritized grid cybersecurity spending increases in 2024 in a survey of utility technology decision-makers.
- 14% of U.S. electricity customers had access to advanced metering infrastructure (AMI) meters in 2022, per EIA smart meter adoption estimates.
- 79% of utilities reported that at least part of their service territory has AMI meters installed in a 2023 utilities technology survey.
- 1.2 million demand response (DR) participants existed in the U.S. in 2023 as measured by program participation counts across major aggregators and regions.
- $1.6 billion in U.S. smart meter and metering infrastructure investment was forecast for 2024–2026 combined in industry projections.
