PREMIER Alan Carpenter’s plan to reserve up to 20 per cent of gas reserves for the state’s domestic economy has met with opposition from Woodside and the premier’s own deputy, Eric Ripper. In announcing his decision, Mr Carpenter said it was unacceptable that WA consumers should pay international prices. Woodside CEO Don Voelte refused to agree to the proposal, likening the move to a tax that would make projects uneconomic. Woodside still plans to go ahead with its development of the Pluto gas field on the North-West Shelf. A discussion paper released by the Department of Treasury caused further headaches for the premier when it suggested the gas reservation policy may be incapable of delivering a low-cost, secure gas supply.
