The Entire Island of Puerto Rico Just Lost Power [Update: Power's Coming Back]

Authored by earther.com and submitted by raysmo

Darkness has fallen on the island of Puerto Rico. All 1.5 million customers of the Puerto Rican Electric Power Authority are currently without power.

This is according to the authority itself, which informed the public via Twitter Wednesday. As far as we know, power isn’t expected to return for another 24 to 36 hours. The power authority is prioritizing power to hospitals, the Luis Muñoz Marín International Airport, gas stations, banks, and emergency units (like firefighters) but is still investigating the cause, according to The Associated Press.

Hurricane Maria struck Puerto Rico nearly seven months ago to the date, and this shit is still happening.

It’s the second major power outage this month, and it comes on the heels of the island’s overall blackout being dubbed the second-longest ever. This most recent slap in the face to the remaining U.S. citizens who live on the island (and haven’t fled to the mainland) is a stark reminder of the island’s fragile electric grid, which is in need of some serious updating.

And we’re less than two months out from the 2018 hurricane season.

Meanwhile, a baseball game at the Hiram Bithorn Stadium in San Juan has resorted to using its emergency system. “The game will go on,” wrote San Juan Mayor Carmen Yulín Cruz on Twitter.

Update 1:15 p.m.: Politicians (former and current) have begun to weigh on on this blackout, as seen from Twitter. Notably, this doesn’t include President Donald Trump—yet.

Update 2:22 p.m.: Justo González, the executive subdirector of PREPA said, in a presser with reporters, that the power outage resulted from subcontractor Cobra Energy excavating a fallen electrical tower to prevent any further damage. “These are high voltages that the excavator should not get too close to,” he said in Spanish. Well, the excavator did, and the power loss was the result. This is the same subcontractor responsible for last week’s power outage when a tree fell on a power line.

González said the authority will not continue to work with Cobra, according to reporter Walter Soto León, who shared footage of the official speaking.

In better news, power has begun to return to municipalities like Toa Baja and Cataño, according to Telemundo. Arecibo, Maunabo, Naguabo, Mayagüez, Vieques, and Culebra also have service, according to PREPA.

Update 5:23 p.m.: Clients in Santurce and Guaynabo now have power, reports the power authority. The Central Unit in San Juan, in the meantime, is generating enough power to “normalize the electric system,” PREPA said on Twitter.

This is a developing story and Earther will update this post as more information is released.

Electrical transmission engineer here, I’ll try to ELI5 this. When stuff hits the live power lines, large circuit breakers exist somewhere that should open up to stop the flow of electricity into that thing that shouldn’t be touching the line. In this case that thing was very close to a generator. The generator tripped offline and now the rest of the island must be carried by the other generators. If the generators cannot output enough to serve that load they will slow down. If they slow too much (which isn’t very much at all) they must shed load (turn off people’s and business’ Power). If they don’t do this quick enough all the generators will stop. The process should be automated but anything can happen. Anyway, generators (power plants) take days to stop and start up. They are huge spinning machines. So that’s why it will take a day or 2 to get it back on. Removing the thing that touched the line is easy. Restarting the generators is very difficult. There was a major breakdown in their automated systems or the event was so bad there was no possibility for a contingency. Some plants or lines in a region can be critical to the stability of the system. If you lose them you lose the system.

we are only 59 min in and there are 20min lines in gas stations, no phone signal or internet so most banks can't give cash again and there are lines in the ice distributing stores.

life's good.

Anyone know what happened?

Edit: After 100+ replies I'm close to understanding
