But once those lines are completed, we think we’ll have a good transmission loop and have some stabilization. There’s two lines coming out of the south, to the north, that we’re still working on right now. You see most of the transmission lines were damaged. Lloyd: From the plant, those transmission lines carry power, and then it goes to substations along the way and continues to step it down until it’s brought to your house. Lizzie O’Leary: And for people who are new to thinking about this, transmission lines are what moves the power from from plant to . And now you have a category 5 hurricane that comes through and rips through the island and causes extreme damage on the transmission lines.
John Lloyd: The infrastructure was unstable before Irma and Maria, so you had a very unstable grid - lot of power outages before the storm. The following is an edited transcript of their interview. Lloyd spoke with Marketplace Weekend’s Lizzie O’Leary about what it takes to turn the lights back on in Puerto Rico, what has been accomplished so far and what is to come. John Lloyd, the Pittsburgh district commander for the Army Corps, is the man on the ground in Puerto Rico leading the effort.
To date, the Army Corps has ordered nearly 40,000 poles, 7,248 miles of cable and thousands of other items to rebuild the power grid decimated in September. Army Corps of Engineers is handling approximately 60 percent of power restoration efforts until March, when its mission is slated to end. Roadside debris, downed trees and fallen power lines mark the damage Puerto Ricans live with on a daily basis. Almost three months have passed since Hurricane Maria made landfall, and much of the island of Puerto Rico is still without power.
