Electric Power Grid Disruptions : A Time Series Examination
2000 . Since Form OE-417 is our principle source of data , we describe relevant reporting requirements ( DOE 2020 ). A sample page of OE-417 reporting in January 2020 is shown in Table 1 .
Table 1 . OE-417 Electric Emergency and Disturbance Report Format
There are three main reporting criteria for electrical outages and incidents for Form OE-417 : 1 ) reporting under normal circumstances ; 2 ) reporting emergency incidents ; and 3 ) system operations . In normal reporting , all routine incidents must be submitted within six hours of the incident ’ s occurrence ( DOE 2020 ). In emergency situations , electrical incidents , or those incidents with the potential of causing major electrical disruptions or damage , incidents must be reported within one hour of the occurrence . System operation incidents resulting in damage or failure , not categorized as emergency situations , are required to be reported within 24 hours of the event , but no later than the next business day .
The following occurrences constitute an emergency as defined by DOE :
• Physical attack that causes major interruptions or impacts to critical infrastructure facilities or to operations
• Cyber event that causes interruptions of electrical system operations
• Complete operational failure or shut down of the transmission and / or distribution electrical system
• Electrical System Separation ( Islanding ) where part or parts of a power grid 201
