Updated through February 2022.

Utility companies and grid operators are required to submit reports on electric disturbance events to the Department of Energy (DOE) on a form known as an OE-417. The publicly available information from these reports is difficult to find, incomplete and confusing. For a detailed description of OE-417s and the reporting criteria, CLICK HERE.
I did an analysis of all the publicly available OE-417 data from January 1, 2010 through the present. (I started in 2010 because that is when the NERC CIP Coverup began.) First of all, there were 166 different “event types” reported many of which were either duplicates or related. For example, there were at least 24 different “event types” that denoted a physical attack. There were at least 50 “event types” that denoted a disturbance caused by weather. I grouped these 166 “event types” into 15 categories (actually “causes”) so that we could get a sense of what has actually threatened the electric grid in the past 10 years.
Unfortunately, the public OE-417 data is so bad that there were 562 electric disturbance events where I was unable to identify a cause. These are highlighted in yellow in the chart. I was able to identify a cause in 2127 electric disturbance events, or 80% of the OE-417 reports filed. Moreover, some data such as the number of “customers affected” does not appear accurate in some cases. Many OE-417’s do not appear to be updated. Reports from years ago show “unknown” under the number of customers affected, or show “0” when we know there were blackouts associated with those events.
Note: After the Texas Grid Collapse of 2021, I started breaking out separate charts for the TRE Region (Texas Reliability Entity a.k.a. Texas RE) in order to give the public better access to what has caused electric disturbances in Texas.
Here is another view of the data by year. Electric disturbance events where I was unable to identify a cause are highlighted in yellow in the chart:

In the below OE-417 Quick Reference Database and CSV file, I added the column “Category” in order to consolidate “Event Types” for statistical purposes. All other data is from Department of Energy (DOE) OE-417 annual summaries.
