Gas Diesel Hybrid Project
Case Studies
Information
In February 2019 Zenith commissioned our 63 MW gas fired power generation facilities at Newmont Gold Corp's Tanami mine.
The Zenith station replaced an existing diesel station, reducing carbon emissions and the cost of electricity dramatically. With two stations, Dead Bullock Soak (DBS) and Granites (GTS)
Zenith commissioned two stations at Newmont’s Tanami mine
Through our internal knowledge of various power station components, Zenith’s proposed an innovative solution to build two stations. One at the processing plant (GTS), and one at the mine itself (DBS), connected by a 45km transmission line. Zenith designed the stations combining three different genset types, each from different genset manufacturers. These being Wartsila, Jenbacher and MTU.
The integration of these three genset types enabled Zenith to reduce the LCOE, whilst maintaining security of supply for the miner. The solution provided an LCOE far lower than using a single genset type.
We use three 20V34DF Wartsila gensets to provide both high efficiency gas generation and also the ability to switch to diesel where the gas quality is poor. The diesel option can also be used when the customer requires a large load to start quickly.
Zenith can move power using the transmission line to minimise spinning reserve across both stations. This allows us to load-share generation and cover off any unforeseen outages at either station.
The transmission line also provides connection points along its route for future solar and wind renewable generation facilities.
