EPSA wins Australia’s biggest mining construction The Roy Hill project

Aiming to produce 55 million tonnes a year, its first ore was mined at the end of April, with exports expected this year. 

The project includes a new mine, a mine process plant, a heavy haul railway system from mine to port and new port facilities. EPSA’s initial role is to supply temporary power generation to the purpose-built port facility, which requires continuous and reliable power up to a maximum demand of 35 megawatts.

“We are designing, constructing, connecting, commissioning, owning, operating and maintaining a temporary power generation facility for an initial two-year agreement, with options to extend thereafter up to 10 years. It is temporary because the long-term intention is to connect the port
facility with the NWIS grid,” says Bill Thomson.

“Our ability to understand Roy Hill’s unique requirements and customise a purpose-designed facility for their demanding environment differentiated us from the competition. It was a very complex brief, but our bespoke approach ensured our success.

“We received notice to proceed at the end of March last year, moved to site in July and already have around 20 staff involved, along with sub-contractors and trades. 

“We supplied Cat® 3516B diesel engines and alternators in a XQ2000 Cat rental configuration power module installed in a 40-foot container. There will be 30 generators, 15 transformers, two 33 kv switchrooms and associated diesel power supply and reticulation systems.

The generators will be built in the US, then shipped to Fremantle and on-transported to site over 1,200 kilometres away. We are currently in the construction phase, with the first eight generators and four transformers installed in October. We will complete commissioning in April.”

The mine site is being concurrently built and, at the time of writing, civil works are being finalised and deployment of primary equipment has begun.

“The mine site power station design is almost identical to the port facility, so leveraging our relationship and replicating cost synergies helped us generate this additional business,” adds Bill.

"THIS TENDER HELPED US TO DEVELOP AND REFINE OUR EPC CONTRACT TENDER PROCESS, AND IS OUR FIRST MAJOR CONTRACT AWARDED UNDER THE REVISED PROCESSES".

“Construction of our infrastructure to support the 80 megawatt standby power station began in September. Core design is now complete for both projects and we have had overwhelmingly positive feedback.

“The Roy Hill project is a triple success for our wider business, with Caterpillar awarded a major mobile mine equipment supply contract for mining trucks and other equipment at the site.”
