In September of 2020, Bergen Engines and it‘s agent Penske Australia signed a commitment with Contract Power to deliver 15 medium-speed gas gensets to power the Iron Bridge Magnetite Project (IBMP).

These gensets are based on Bergen‘s 20-cylinder B36:45 gas engine, which was introduced to the global market at the end of 2018 when it set a new standard in power and efficiency, with exceptionally low fuel consumption and emissions. Through the Pilbara Generation Project, the gas gensets are integrated with a 150MW solar photovoltaic farm and battery storage. The hybrid energy system is connected to a new transmission network Fortescue has built in the Pilbara, ensuring that the right amount of electricity is supplied in a reliable, efficient and environmentally-friendly manner.

Jamie Cullen, Chief Executive of Pacific Energy, parent company of Contract Power said: “The Bergen B36:45 gensets are low-emission units with market-leading fuel efficiency, which delivers low-cost clean energy to support Fortescue’s growing penetration of renewable energy in the Pilbara Energy Connect program.”
