The Puerto Rican grid is already partly segmented - Mayagüez was on a minigrid even before Hurricane Maria. The fact that Mayagüez was the only city on the island that retained power after the hurricane was not lost even on PREPA. (An aside: I first made it over to Mayagüez in the second week after the storm, hoping to find a cell phone I could use for Internet access - National Hardware not only had power but working telecommunications, so I could actually buy a few supplies on my Visa card. And their air conditioning was working. It was literally like walking through another world.) Adjuntas is working on getting their downtown on a separate solar minigrid. Everybody thought this was a particularly good idea this week, as the power was out downtown on Wednesday.
