Clarke Energy Executes Performance Based EPC Project at Werribee Utilising Jenbacher Gas Generators

Clarke Energy designed, constructed and commissioned a new biogas to energy power station, known as Werribee Power Station B, located in Werribee, Victoria. The EPC project was a mixture of greenfield and brownfield sites located at Melbourne Water Corporation’s (MWC) Western Treatment Plant, with the main power generation plant being located adjacent to the existing Werribee power station. The power station was designed to operate in parallel to the wider grid, whilst having potential to operate in island/off-grid mode. Clarke Energy’s internal expert engineering team skilfully designed the performance-based project to meet MWC strict requirements.


This Clarke Energy project provided a complete EPC power station solution featuring two Jenbacher J620 engines surrounded by drop over enclosures, with gas conditioning and 22kV export to an adjacent switch room. The design allows for a third gas generator set and gas scrubber system to be installed in the future as gas supplies increase.

The Jenbacher J620 is a V20-cylinder power generation solution, with a power output of 3,360KW and industry leading efficiencies. The J620 is a great choice for medium and large power plants such as the stage four project at Werribee.

The Werribee project involved brownfield works, including 6 kilometres of biogas pipelines, process water and effluent for H2S wet scrubbing. Process water pumps and a new switch room were installed at an existing pump station located at pond 4.

MOLEC, a Clarke Energy subcontractor, recently received the prestigious NECA Excellence Award 2020/21 (Victoria) for this project, recognising outstanding achievement across the electrical and communications industry in Australia.

Tom Kelly, Director at MOLEC says,
“MOLEC has worked closely alongside Clarke Energy on numerous projects since 2005, this project is no different. Our team prides itself on delivering high quality outcomes on time and on budget while maintaining stringent OHS, Environmental and quality standards, and it is with this commitment to our customers and partners which allowed us to Win this NECA Victoria award for this project in 2020/21.”

Jeff Stevens, Site Construction Superintendent at Clarke Energy says
“Projects such as the stage four power plant installation at Werribee show Clarke Energy’s ability to carry out medium to large scale, fully integrated EPC projects working together with our contractors for our customers.”

The NECA Awards give members and their apprentices the opportunity to achieve the highest accolades available, and to demonstrate their top projects to their peers, the wider industry and the community.
