More than 360 temporary power generators were in place on Puerto Rico as of October 31, according to the U.S. Army Corps of Engieers. The number surpasses the 310 generators installed by the corps during Hurricane Katrina recovery efforts in 2005.

Sgt. Mike Greenwalt of the 249th Engineer Battalion ensures all power is discharged from the generator before continuing work on the generator. The generator was installed at the Barceloneta Water Treatment Plant which provides water to a large number of factories in the area. With power restored, factory workers will be able to return to work. Credit: USACE photo by Mike A. Glasch Sgt.

Generators are being installed at the rate of 20 a day.

The 366 generators currently installed across Puerto Rico are providing more than 122 megawatts of generating capacity to 48 hospitals, 44 waste water facilities, 190 water pumps, 30 emergency services facilities, 10 airports and other critical facilities. Puerto Rico’s power grid is operating at approximately 30% of pre-storm capacity.

After being hit by two hurricanes, the second a category four, within 12 days, the U.S. territory’s power grid was largely destroyed under the force of Hurricane Maria’s 155 mile per hour winds.

The Emergency Power PRT, one of seven in the Ccrps, teams with the U.S. Army 249th Engineer Battalion “Prime Power,” and partners with contractors to provide power generation to the island.
