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.
