5 Other Peak Intermediate Sources of Market Supply Type Commentary Gas Producers GSA flex has historically been the primary source of swing services to the domestic markets Reservoir and other storage expected to become a more economic alternative to swing supply in the future Reservoir Storage Current limited diversity of operating reservoir storage facilities Variable reservoir quality - some existing assets have significant storage capability but low withdrawal rates Access and haulage costs to market are an important consideration Lochard s facility at Iona has a unique blend of high storage volume/ high withdrawal rate and direct access to Victoria and South Australia LNG Storage Current facilities at Dandenong (Victoria) and Newcastle (NSW) Role limited to super peak days due to limited storage and slow refill rates (depleted in ~10 days or less) Linepack Insignificant capacity relative to underground storage and production flex Role limited to meeting super peak Interstate Imports Spot price deviations between regions will continue to incent transfers e.g. from Queensland to the Southern states on peak days Pipeline access, cost and firmness of supply are important considerations LNG Imports LNG import terminals under consideration in Southern markets Could play a role in future gas supply - particularly if shortages develop in Southern markets 5

10 Implications for Storage Developments Market Fundamental Increased demand for natural gas from LNG exports Implication Tightening of gas market drives demand for new upstream and midstream investment Reducing supplier diversity Lack of new upstream projects and diversion of gas to Queensland is reducing supply diversity and increasing system risk Loss of Producer swing Producer preference to minimise swing in Gas Supply Agreements Low oil prices Low oil prices stifle investment in the upstream and midstream Increased renewable penetration Intermittency of renewables likely to require capacity support from gas fired generation and other sources Decarbonisation Decarbonisation trend combined with Australia s aging coal generation fleet is expected to drive transition towards increased renewables and gas fired generation, which in turn drives demand for storage 10
