The 16 pages that link to Power outage, each with the reason it gives.

• Load balancingCompared with: Severe, unmanaged imbalances can contribute to outages and cascading failures.

• Electrical gridRelated: Failures or imbalances can interrupt service across connected parts of the grid.

• Overhead power lineRelated: Storms, equipment failures, and vegetation contact can interrupt overhead circuits.

• Uninterruptible power supplyRelated: An outage is the interruption a UPS is designed to bridge, not a disturbance it can prevent.

• Freezing rainRelated: Ice loading can break branches and power lines, interrupting electricity service.

• Electricity demandRelated: Demand exceeding available supply or network capability can contribute to outages.

• Protective relayRelated: Incorrect or overly broad relay trips can turn a local fault into a wider outage.

• Transmission lineRelated: Line faults and cascading network effects can cause outages across connected regions.

• Winter storm warningRelated: Heavy snow, ice, and wind can damage power lines during warned storms.

• Hurricane IrmaRelated: Irma disrupted electricity for millions of people across the Caribbean and Florida.

• Ice stormRelated: Ice-laden branches and lines can break, interrupting electricity across wide areas.

• Winter stormRelated: Ice and heavy snow can damage power lines and leave communities without heat.

• Electrical faultRelated: Protective isolation or fault damage can interrupt service beyond the faulted component.

• Electric power qualityCompared with: An outage is a complete interruption, unlike many quality disturbances that occur while supply continues.

• Electricity (electric power)Related: Outages reveal how strongly homes and essential services depend on continuous supply.

• Underground power lineRelated: A buried cable fault can interrupt service while crews locate and repair the damaged section.
