BHP Billiton has opened its $1.5bn Macedon domestic gas project in Onslow, in Western Australia.

The BHP Billiton-operated facility, which commercialises natural gas from offshore production lease WA-42-L, situated in the Exmouth Sub-Basin, commenced first gas on target in August 2013.

BHP Billiton conventional asset president, Steve Pastor, said the company is playing a vital role in securing a diverse energy supply for Western Australia.

"Macedon is BHP Billiton’s largest operated Australian domestic gas project and is expected to supply domestic gas for the wholesale market in Western Australia until at least 2033," Pastor added.

According to the company, the operation is said to supply 20% of the state’s daily domestic gas supply for consumers and industry.

The facility is also expected to build on the company’s oil and gas operations in Western Australia, which include interests in the North West Shelf as well as the Exmouth Sub-Basin.

"According to the company, the operation is said to supply 20% of the state’s daily domestic gas supply."

With a production capacity of up to 200 terrajoules of gas per day, the plant has operations, including four offshore production wells and an onshore gas treatment plant, at the Ashburton North Strategic Industrial Area in Onslow.

Gas produced at the Macedon plant will be exported to the Dampier to Bunbury Natural Gas Pipeline for sale to the markets of Western Australia.

The company said it has plans to invest in the future growth of the area through its State Development Agreement, during the productive life of the asset.
