Electric utility reliability performance has hit the news recently due to weather and other natural disaster events. We thought it useful to compare the performance of different regions around the world, although we note these graphs exclude outages caused by major events. Europe has consistently improved across most nations, and Australia has had very variable performance. The USA has not seen much change over the 10-year period to 2010.
