Puerto Rico’s energy strategy is undergoing a quiet but meaningful shift, with liquefied natural gas (LNG) playing a more central role in stabilizing the island’s grid. The first year of operations for the U.S.-flagged LNG carrier American Energy, operated by Crowley, signals a step toward a more structured and reliable fuel supply model.
Since launching service in March 2025, the vessel has delivered more than 2 million cubic meters of U.S.-sourced LNG to the island. That equates to roughly 549 million gallons—enough energy to power an estimated 1.2 million homes annually. For a grid long challenged by outages and fuel constraints, that level of consistency matters.
The shift also reflects a broader move away from diesel-heavy generation. LNG use has cut associated emissions by close to 30% compared to traditional fuels, positioning natural gas as a practical, if interim, option in Puerto Rico’s longer-term energy transition. While not a zero-carbon solution, LNG is increasingly being treated as a bridge between legacy systems and future renewables.
