What is a power outage database?

This database records detailed information for every power outage, such as the start and end times, addresses and areas affected, and causes of power outages. The high-resolution data makes it possible to link the variation of power outages to other important outcomes in the energy systems such as EV adoption.

How long does a power outage last?

Half of U.S. outages caused by major events last longer than 12 hours, and more than a third last longer than a day, according to the National Renewable Energy Laboratory. That translates to more days when outdoor air is affected by people firing up their generators.

How many power outages a day?

Some districts experienced >1500 counts of power outages and >14,000 h during the 669 days, which is equal to an average of 2.24 power outages and 21 h with no power per day.

How will a power outage affect the electric grid?

With elevated electricity demand and the associated uncertain impact on the electric grid from electrification, together with increased natural disasters and extreme weather events, as well as increased penetration of renewable energy in the electricity generation mix, power outages could cause more challenges in the near future.

What causes power outages?

Countries such as China and the U.S. have experienced increasing pressure from power outages due to extreme weather events such as winter storms, heat waves, hurricanes, and wildfires.

Why is energy storage oversupply a problem?

The expansion is driven mainly by local governments and lacks coordination with new energy stations and the power grid. In some regions, a considerable storage oversupply could lead to conflicts in power-dispatch strategies across timescales and jurisdictions, increasing the risk of system instability and large-scale blackouts.
