Understanding Puerto Rico's Infrastructure
Puerto Rico's infrastructure — power grid, water systems, roads, bridges, ports, and public facilities — was severely damaged by Hurricane María in September 2017 and had already suffered years of deferred maintenance tied to the island's fiscal crisis. On the power side, PREPA (Puerto Rico Electric Power Authority / AEE) owns the generation assets and has been in federal bankruptcy since 2017; LUMA Energy took over transmission and distribution in 2021 under a public-private partnership, with frequent outages remaining a persistent public debate. Drinking water and wastewater services are operated by PRASA (Puerto Rico Aqueduct and Sewer Authority / AAA). Federal recovery funds from FEMA and HUD CDBG-DR have allocated tens of billions for rebuilding roads, bridges, the grid, and water systems, though disbursement has been slow.
Key points
- PREPA/AEE is the public power authority; it owns generation plants and has been in federal bankruptcy (Title III under PROMESA) since 2017.
- LUMA Energy took over transmission and distribution in June 2021 under a 15-year contract — outages and its performance remain a major public debate.
- PRASA/AAA operates the island's drinking water and wastewater systems, serving all 78 municipalities.
- The Puerto Rico Highways and Transportation Authority (PRHTA/ACT) manages roads and highways; Hurricane María caused an estimated $90 billion+ in total island-wide damages.
- FEMA and HUD CDBG-DR have allocated tens of billions for rebuilding, though complex federal requirements have slowed actual construction progress.
