SAN JUAN, Puerto Rico - At the request of Puerto Rico Governor Ricardo Rosselló, the Federal Emergency Management Agency (FEMA) tasked the U.S. Army Corps of Engineers to maintain and repair non-federally installed generators. The U.S. Army Corps of Engineers deployed their Honolulu District Temporary Emergency Power Planning and Response Team and contracted with Louis Berger to take on this unprecedented mission.

The significant damage caused by Hurricane Maria to the island's power infrastructure resulted in long-term power service disruptions. Jackie Conant, mission liaison said the additional PRT was deployed to supplement the work being performed under the traditional temporary emergency power mission which is responsible for providing temporary emergency power to critical public facilities with Government owned or leased generators.

"The goal for the supplementary temporary power mission is to repair and maintain the facility owned, permanently installed generator to prevent the requirement for a FEMA provided generator to be installed at the facility or to allow an already installed FEMA provided generator to be de-installed from the facility and used for other critical needs," Conant said.

Unlike the traditional Temporary Emergency Power mission, which installs FEMA provided generators from a pre-determined list of manufacturers, the "Non-Fed" team has to be prepared to service, maintain and repair generators from all makes, models, sizes, and ages.

"This is a unique, never been done before, mission with a variety of challenges," said Recovery Field Office Commander Col. James DeLapp. "There are generators in use that are no longer being made, one generator that we recently repaired is almost 60 years old."

To date FEMA has tasked the "Non-Fed" team with assessing 148 facilities containing approximately 180 generators. They have completed 85 assessments with 29 still in progress. The "Non-Fed" generators are providing power to hospitals and clinics, waste water treatment plants, water pumps, telecommunications hubs, and other facilities deemed critical by FEMA.

"At the moment about 40 percent of the generators are fully working," Conant said. "As we continue to receive parts and help from technical experts more generators will be working at full capacity."

"Similar to the upkeep of a car, a generator requires maintenance and repair due to usage," said Darin Aihara, mission manager. "Once a facility is approved by FEMA to be included under the maintenance and repair of non-federal generator mission, the facility is assessed by an assessment team and the team determines if the generators require repair, maintenance, or both."

Typically, for emergency or stand-by generators, most manufacturers recommend servicing every 240 hours of runtime. The 240-hour servicing includes the replacement of the oil and fuel filters, and the visual inspection of the air filters, belts, and radiator coolant quality and levels. "Like a car, regular maintenance of the generator will keep the generator at optimal performance and prolong the life of the generator," Aihara said.

If an assessment reveals that repairs are required, as soon as the parts are available, a team of electricians and mechanics will be sent to the generator and perform the repairs. According to Conant, if the assessment determines the generator is irreparable or if the repair exceeds the allowances of the mission, the facility will be able to request the traditional temporary Emergency Power mission to install a FEMA provided generator until commercial power is restored.

"The devastation caused by Hurricane Maria continues to provide different and changing environmental challenges to missions like the "Non-Fed" generator maintenance and repair mission," said DeLapp. Hurricane Maria's damage to Puerto Rico's ports, airfields, roads, bridges, electric grid and communications has slowed some recovery efforts but conditions and the pace of recovery continues to improve daily."
