Queensland-based gas producer Westside today announced gas sale agreements (GSAs) with Alinta Energy and CleanCo Queensland, totalling 5.84 petajoules (PJ) over three years.

Under the GSA with Alinta Energy, Westside and its joint venture partner, Mitsui E&P Australia Pty Ltd, will deliver a total of 3.65 PJ in calendar years 2022 and 2023.

CleanCo Queensland will purchase a total of 2.19 PJ of gas over 2023 and 2024 to fuel Swanbank E, CleanCo’s highly efficient 385 MW gas-fired power station near Ipswich in south-east Queensland. Swanbank E plays a key role in ensuring the ongoing reliability and stability of Queensland’s electricity network and allows CleanCo to offer low-emissions, reliable power to customers.

The gas will be sourced from Westside-operated Greater Meridian fields in Queensland’s Bowen Basin, which currently support average daily production of 39 terajoules (TJ) on a gross basis.

Westside has secured separate gas transportation agreements with Jemena to deliver the purchased gas to Queensland’s central gas hub at Wallumbilla.

Westside CEO Matt Wallach welcomed the new GSAs, saying they would diversify the company’s customer base and pricing mix.

“With a strong record of production growth and reliable delivery, Westside has emerged as a significant gas producer.

“Through these GSAs we’re pleased to be contributing to increased supply to the domestic east coast market, in line with government policy objectives,” Mr Wallach said.
