Corvus Energy is proud to announce that the battery energy storage system (ESS) powering the largest battery electric ferry has been successfully delivered, installed, commissioned, and has entered commercial operation in South America.

The vessel, China Zorrilla, built by Incat Tasmania for Buquebus, has arrived in Argentina and has been undergoing final testing before entering service between Argentina and Uruguay. Powered by more than 41 MWh of Corvus Energy battery systems, China Zorrilla features the largest battery installation ever deployed onboard a ship and represents a landmark achievement for maritime electrification.
