In 2013, for instance, a power failure in San Francisco’s San Jose Electric Service District caused a total loss of 24 megawatts and an estimated $4 billion in damage.
Power outages happen in nearly half of the nation’s major metropolises, according to a study by the California Public Utilities Commission. In San Francisco, for instance, more than 1,000 power outages have occurred over the last바카라사이트 10 years, resulting in more than 6,800 lost hours of service.
In many cases, the power failure isn’t caused by any fault with the electric system itself, but by problems caused by faulty or dangerous wiring.
A system failure in a San Francisco utility
The situation is so common that an employee with the San Francisco Public Utilities Commission’s energy department says there is no other service in the world that could potentially go to hell so quickly and dramatically.
To test out the power of such a backup system, the utility sent electrical engineers and their colleagues to a power plant in the California desert.
The team went up to work at 6,000-year-old Mesquite, located some 35 miles west of San Francisco, during the late-summer heatwave of 2013.
Here’s what their test power looked like at the time of the outage, according to the commission.
As you can see, Mesquite was suffering the effects of massive electrical supply failures, which included power loss.
The utility’s scientists used some sort of computer model to predict what would happen if a system failure occurred at 6,000-year-old Mesquite power plant in Southern California, California. In the top right corner of the chart, the utility predicted, for example, that on Jan. 24, 2013, a failure at one of the nearby substations would cause the entire system to be out for a full week, and that some parts would not be repaired for 18-24 hours.

The test model — called a grid-scale network simulation — helped determine if the system could be restored to normal status within 72 hours of the failed power line.
At no point, however, did the grid-scale grid-scale simulations show anything that suggested the outage at Mesquite was a failure of the power syste
