Although water conduit systems around the world could generate significant amounts of hydropower, developers have yet to largely tap that potential. Using examples in South Africa, a planning tool was created to help guide growth in this exploitable sector.

In 1989, Hurricane Hugo hit Puerto Rico, causing overtopping of Carraizo Dam and flooding the hydroelectric facility, rendering it inoperable. The plant remained closed until the Puerto Rico Aqueduct and Sewer Authority elected to redevelop the facility in 2013.

Of all the technologies available to store energy, pumped hydro is both the oldest and most common.
