Relatively, Michigan continues to be the worst state in the Midwest for reliability performance, and ranked 50th out of 50 states plus DC for SAIDI including major event days (outage duration per customer served) and 51st for CAIDI including major event days (average restoration time). For example, Ohio residential customers pay 15.38 cents per kWh and Indiana residential customers pay 14.94 cents per kWh, while utilities in those states also perform better on reliability metrics. The second-worst state in the country was Maine, averaging over nine hours to restore power. On average, in Michigan it took about 12 hours to restore power following an outage in 2023, over twice as long as any other neighboring state. Since acquiring C Space and Hall & Partners in 2023, we’re a team of 1,600 market research consultants turning complex data into strategic insights that empower businesses with actionable intelligence.
While we should take steps to mitigate against these impacts, our work shows that a more robust option is to also support the buildout of a diverse set of technologies that make catastrophic, cascading reliability issues an extremely low probability event. Work at the Center on Energy Policy indicates that the most robust pathway to an affordable, reliable, and clean electricity sector includes a mix of technologies. The broader economic impact of the storms of February 2021 has been estimated at upwards of $300 billion. But this number hides the significant variability between states and customer types, as well as the difference between loss of transmission or distribution lines or outages caused by loss of generation.
Utilities must submit reports on system performance, and failing to meet benchmarks may lead to regulatory penalties or mandated corrective actions. Reliability data helps utilities address these concerns and ensure better service quality. Reliability metrics help pinpoint weaknesses, allowing utilities to prioritize infrastructure upgrades and maintenance efforts. Without proper reliability measurement, utilities would struggle to identify areas that need improvement.
Measuring power system reliability is essential for electric utilities because it provides valuable insights into the overall health of the electrical grid. Standard IEEE 1366–2022 provides guidelines for defining and calculating reliability indices, helping utilities assess system performance and implement improvements. The chart below shows S&C’s interpretation of the key reliability metrics, the present relative level of utility use of the metrics, and our view of how this should change so there’s a greater focus on customers. The inclusion of more customer-centric metrics as part of a suite of reporting can provide a more complete picture that includes reliability experienced by worst-served customers. Simultaneously, consumers and businesses have become more reliant on electricity for digital services and transportation, and they have come to expect uninterrupted service. However, the most used reliability metrics, such as the System Average Interruption Frequency Index (SAIFI), the System Average Interruption Duration Index (SAIDI), and the Momentary Average Interruption Frequency Index (MAIFI), don’t tell the whole story.

- Historically, FPL’s reliability and outage communication scores have improved based on how well it manages extreme weather events, and we have measured improvements for other utilities that performed well during weather events.
It regularly communicates details and stats about these reliability improvements on its website and through frequent social media posts, building trust with its customers. The utility, which has seen intensifying hurricane seasons in the past few years, has been making significant grid improvements since 2006. This demonstrates the importance of educating consumers about the connection between reliability and resilience, and https://commonpost.info/evaluating-capital-expenditures-in-global-mining-infrastructure/ how they ultimately benefit.
However, while reliability is consistently the strongest driver of customer satisfaction, very few consumers support a rate increase to strengthen that reliability. After an outage, 77% of consumers expect their utility service to be restored in fewer than 2 days. Increasing in number and frequency, these major events are shaking consumers’ confidence in utilities, driving the need for these companies to clearly demonstrate the value they provide, especially as rates increase. As a result of the assessment, EPRI recommended the establishment https://heplerbroom.com/blog/wotus-and-pm-naaqs-and-pfas-oh-my-environmental-highlights-in-first-quarter-2023 of a Reliability Engineering Group (REG) to make impartial reviews and recommendations on the prioritization of capital and maintenance programs.

Customers do https://dnews7.com/kiev-shipping-ltd-has-been-the-best-break-bulk-cargo-brokers-since-2000.html not get to exclude major event days from their lives – they must live with the long power outages that result. Before joining Escalent, she was director of customer engagement and insights at Chartwell, where she led a team of analysts in the development and delivery of utility research to address pressing industry needs. Historically, FPL’s reliability and outage communication scores have improved based on how well it manages extreme weather events, and we have measured improvements for other utilities that performed well during weather events.
After reviewing the 2017 reliability reports, Staff identified significant inconsistencies in the types of information utilities were reporting as well as categories of information included in the reports that were largely unrelated to reliability. The EIA 861S is essentially a shorter version of Form EIA-861 and does not include reliability data. For this comparison, the average for the Southwest states includes data from utilities in Arizona, California, Colorado, New Mexico, Nevada, and Utah. The video can be accessed here; the presentation runs for the first 45 minutes of the video including questions from Commissioners. The February 17th, 2021, Commissioner Committee Meeting on Emerging Trends contained a presentation explaining the reliability metrics and how they are used. MEDs are defined by IEEE 1366 as days in which the daily SAIDI of an event exceeds a statistically defined threshold based on the previous 5 years of daily SAIDI data.

Every public water supply and wastewater utility should assess the likelihood and consequences of a power supply disruption, identify critical vulnerabilities, and consider alternative power or supply redundancy to mitigate service disruptions. It is imperative that these assessments of potential power disruptions include participation and input from your local electric utility. Every utility is unique with respect to its vulnerability to electric supply disruption and must undertake a critical assessment of the issue based on specific local conditions. AWWA believes that every water and wastewater utility should set uninterrupted service as a high priority operating goal and include potential service interruptions in its risk assessment and resiliency plan in compliance with the American Water Infrastructure Act (AWIA). This data-driven approach helps utilities justify investments in storm resiliency projects, improving reliability and minimizing customer impact during extreme weather events.
This metric represents the average time required to restore service when an outage does happen. The Florida Public Service Commission (PSC) ensures that Florida’s consumers receive some of their most essential services—electric, natural gas, telephone, water and wastewater—in a safe, reasonable and reliable manner. The Outage Map includes information on the size and location of an outage and estimated restoration times.
