Fluor Corp. says it has completed work on two 115kv transmission lines between substations in Sabana Llana and Canóvanas in Puerto Rico.

The work is being done under a contract with the U.S. Army Corps of Engineers in support of recovery work managed by the Federal Emergency Management Agency (FEMA) in the aftermath of Hurricane Maria, which destroyed much of the island's electric infrastructure in September.

As of January 4, around 58 percent of the island's electric power customers had service restored to them, according to the Puerto Rico Electric Power Authority.

In early December, Fluor was awarded a task order worth as much as $831 million under its contract with the U.S. Army Corps of Engineers Huntsville (Alabama) Engineering Center to help with the restoration and rebuilding of transmission and distribution lines in Puerto Rico.

The competitively awarded contract includes evaluation, restoration, repair and replacement of structures and equipment supporting the island's electrical infrastructure.

The three-month single award task order was funded at $495 million with a ceiling of $831 million and is the second awarded to Fluor for power restoration work in Puerto Rico.

A previous task order for $240 million was awarded on Oct. 16, with an additional $261 million added to the original task order on December 4. Both task orders represent work assigned to the Corps by FEMA as part of its recovery work. The contracts were competitively bid and awarded to Fluor under a Basic Ordering Agreement contract.

Fluor has previously completed work on multiple distribution lines on the island, which connect to the transmission system and are part of the last stage in getting power to Puerto Rico's homes and businesses.

The completion allows the Puerto Rico Electric Power Authority (PREPA) to re-energize lines in a major urban center that will carry electricity to large neighborhoods, churches, pharmacies, a retirement home and a retail center in Canóvanas.

Fluor has more than 1,800 people on the island working to restore power.
