We’re extending Zenith’s existing power station at King of the Hills (KOTH) to support Vault Minerals’ plant expansion at Leonora.
Zenith has been powering KOTH since March 2022 with a hybrid solution integrating gas, solar PV and BESS—and the station was designed from day one to enable future renewable integration and site expansions.
That day has arrived. Zenith is now delivering a two-stage expansion of the existing KOTH power station to support Vault Minerals’ broader plant upgrade program at Leonora.
