It’s essentially a gravity-powered battery that can generate 12MW for up to 8 hours. Bonus points: locals call it "the waterfall that flows backward." Malabo’s engineers are experimenting with storage solutions that’ll make your smartphone jealous:
[pdf] The project, owned and operated by AES Distributed Energy, consists of a 28 MW solar photovoltaic (PV) and a 100 MWh five-hour duration energy storage system. AES designed the unique DC-coupled solution, dubbed “the PV Peaker Plant,” to fully integrate PV and storage as a power plant.
[pdf] The project encompasses the construction of a solar and battery energy storage system (BESS) minigrid to be built on the island of Buka, within the autonomous region of Bougainville in Papua New Guinea. It will address the electricity needs of the region, which relies heavily on diesel generators.
