Abstract
These are interesting times for the eastern Australian gas market with Liquefied Natural Gas (LNG) projects coming online. The previously steady and long-term contract market for domestic gas supply on the east coast will be subject to market forces that are in part determined on the global stage. How will the market respond to these changes? The answer requires a comprehensive analysis of several scenarios and sensitivities around market models, as well as sophisticated modelling to capture these possibilities. This requires a tool that allows detailed modelling of the physical delivery of gas from producing fields, through pipelines and storages (including linepack) to demand points, with the capability to model any physical/financial constraint along the supply chain. The future lies in these scenarios and sensitivities. Employing a model developed through PLEXOS® gas module, this extended abstract analyses the effect of LNG on the domestic gas prices and supply in the short-to-medium and long-term. To establish any potential risk of gas shortage or particularly high prices, an analysis of the market was carried out from 2014-2023. Running several sensitivities on the demand forecast in this period, LNG effects on the market operations are examined.
