• ​150 terajoules per day to flow to WA customers
• Secure energy supplies fundamental to economic growth and creating jobs

Western Australia's energy supply has been further secured, with the first natural gas flowing into the State's integrated domestic system from the Chevron-operated Gorgon Project.

State Development Minister Bill Marmion said the Government was committed to the domestic reservation policy, with the gas to be supplied to Synergy and customers.

"Gas is fundamental to our lives, providing energy to industries which support thousands of West Australian jobs.  That is why this first 150 terajoule per day tranche of domestic gas from Gorgon is such an important milestone," Mr Marmion said.

"As the project becomes fully operational, domestic supplies from Gorgon could increase to 300 terajoules per day.

"This gas is another economic benefit from this immense project, with $34 billion invested to date within Australia, and 455 contracts awarded to Western Australian companies."

Energy Minister Mike Nahan said the Gorgon Project would supply foundation customer Synergy with 125 terajoules per day of gas over the next 20 years.

"This significant long-term contract with Synergy ensures supply into the future for the State's industrial, commercial and household use," Dr Nahan said.

"Natural gas continues to be an essential energy source as a reliable and cost-effective way to generate electricity.

"It plays a key role in ensuring we are able to meet our energy needs of the future and in providing a clean energy future."
