As of 11/30/17 status.pr is reporting that generation is at 65% http://status.pr/Maps/Map/AEE
This stat is not clear as to whether it is how much is being generated and as a percentage of what, Nominal capacity? or whether it is a percentage of customers or area with service.
I note that the offshore islands of Vieeques and Culebra still have no power at all. PREPA used to have plants on each island. Are they still there and inoperable? Been removed?

Humacao and Ceiba generator status
Yesterday, 11/29/17, I visited the Humacao plant. This consists of 2 25 MW (I think) gas turbines. One of them was running, though judging by the heat plume at somewhat less than full capacity. The other was not. I had always understood these to be 25MW but talking to someone at the site I was told that they were only 20MW each and that they were diesels. They are obviously not diesels and the guy first tried to tell me they were "20 megabyte" capacity so I am not sure I got the straight story.
They were also in the process of installing a new generator. That was also "20 megabytes" I am guessing from appearance that
it is a gas turbine.
The Ceiba plant is just down the road from me and I understand it to be 2 25MW gas turbines running on diesel fuel. It took about a month after the hurricane to fire up the first unit. The second one, I am informed, was inoperable. It was finally repaired and placed in service last week. When I drove by yesterday, both were running
3 weeks ago I was speaking with someone from Manati who told me at that time that the gas turbines (2 @25MW each) were not running. They did not know if they were inoperable or what the reason for being off was.

PREPA Generating capacity
Does anyone have information about PREPA generating facilities? Based on my personal knowledge and experience as well as Wikipedia, I know about the following:
South Coast
AES Puerto Rico 454 MW Guayama (Coal, Privately owned)
Aguirre Combined Cycle 592 MW Salinas
Aguirre Thermoelectric 900 MW Salinas
Costa Sur 990 MW Guayanilla
EcoEléctrica[15] 510 MW Peñuelas (Natural gas, privately owned)
Total capacity south coast 3,446 MW
North Coast
Palo Seco 602 MW Cataño
San Juan Combined Cycle 464 MW San Juan
San Juan Thermoelectric 400 MW San Juan
Cambalache 247 MW Arecibo
Total capacity north coast 1,713MW
The above capacities are from Wikipedia. All plants are owned by PREPA and are oil fired except as noted.
I have shown them as north and south coast since the big problem right now is that the plants in the north are not operating and/or capable of providing sufficient power. The big problem is transmitting power from south to north.
Additionally, there are a number of gas turbines around the island for load balancing and peaking power. The ones I know about are:
Ceiba 50 MW
Humacao 50 MW
Vega Baja 50MW
Mayaguez 220MW
I believe that there are several others, including at least one station in the Metro area. If anyone has additional info about locations and capacities, please let me know and I will revise the list.
What I would really like, and can't find, is a map showing all generating stations and capacities. PREPA does have a site https://www2.aeepr.com/Investors/OperationalProfile.aspx showing major facilities but it does not show the smaller facilities.
PR Energy Commission's site at http://energia.pr.gov has some maps of distribution lines but not of transmission lines or generating stations.
Capacities above are nominal, not actual. For example, Palo Seco is non-operational. The San Juan plant is operating at reduced capacity (as I understand it and observed from the stacks 2 weeks ago)
There are several solar and wind facilities. These provide minimal power, probably less than 50-75MW total. That is usable power, not nominal power. For example, the Humacao solar plant, now destroyed, was rated at about 40MW but that assumes constant sunshine 24 hours a day. Actual capacity was probably more equivalent to a 10MW conventional plant. I do not consider Solar and wind significant to Puerto Rico's power supply.
PREPA also has a number of hydro plants rated at 156MW. I am not very familiar with these but my understanding is that they operate at significantly less output than this.

Welcome to Dark Island PR
Puerto Rico has been the dark island since September. We cannot get reliable information about our utility, Puerto Rico Electric Power Authority (PREPA) in Spanish Autoridad de Energia Electrica (AEE). Not from the newspapers, not from the government, not from the media.
I have lived in Puerto Rico since 1971 and have some familiarity with the PREPA system. I will share my knowledge here along with what information I can find from various sources.
My knowledge is far from complete or up to date. I also cannot guarantee accuracy. There are many people out there who have knowledge of various pieces and practices of the system. I am hoping that this blog can become a site for collecting this information to give a better picture of what is going on, what has been done and what should be done.
The blog language is English so that those in the upper 50 can take part. I am bilingual and Spanish posts or comments are welcome.
