East Spar wins contract to supply new cogeneration unit

Santos Ltd announces that the Apache operated East Spar Joint Venture has signed a new sales gas contract with Alinta Ltd to supply up to 90 petajoules of gas from the East Spar Gas Field in the Carnarvon Basin, offshore Western Australia.The gas will be supplied to fuel Alinta’s new gas-fired co-generation unit, in Pinjarra, south-west Western Australia which is expected to be commissioned in 2005. The co-generation unit will supply steam to Alcoa Australias Pinjarra Alumina Refinery as well as electricity to other customers.

Alcoa has announced that it will invest $A440 million on an efficiency upgrade of the Pinjarra refinery.

The full contract daily volume when the plant is commissioned will be 23 terajoules per day.

The East Spar field, which commenced production in 1996, delivers approximately 125 terajoules per day for sale to various customers in and around Perth and in the Western Australian Goldfields.

In addition Alinta has already commenced taking small additional volumes of gas under the contract. This increased gas production will result in increased condensate production from East Spar.

East Spar gas is processed on the nearby Varanus Island in the Carnarvon Basin and then transported to Compressor Station 1 at the junction of Dampier-Bunbury and Goldfields transmission pipelines.

It is particularly pleasing to sign a new contract in the highly competitive Western Australian gas market and to be building our gas franchise, said Santos’ Managing Director, John Ellice-Flint.

The co-generation unit is an exciting and important project for Western Australia and Santos is delighted to be a part of the development, said Mr Ellice-Flint.

Interests in the East Spar Joint Venture are:

  • Apache Oil Australia Pty Ltd (operator) 55%
  • Santos (BOL) Pty Ltd 45%
