Younicos is to replace a lead-acid battery storage system at one of the largest wind farms in Hawaii with Samsung SDI lithium-ion technology.
Younicos, a subsidiary of Scotland-based Aggreko, said it has signed a deal with US renewable power operator, TerraForm Power, to install a 10MW lithium battery system that marries with its Y.Q Younicos’ control software, to upgrade energy storage at the Kaheawa wind farm, on the island of Maui.
The battery installation is expected to be completed in the second half of 2018.
Younicos claimed the move will allow “significantly higher usable energy capacity potential” and increase the operational lifetime of the Maui system. The replacement system is fully automated, the battery firm said.
Last December, Younicos won a contract to supply a 1MW/1.3MWh battery storage system connected to “the world’s first floating wind farm“, Hywind Scotland.
Aggreko acquired Younicos last year for GBP40 million ($51.8m).
