Key gas observations for the month ending 16 December 2018:
Gas prices in NSW, QLD, SA and VIC all increased over the last month relative to the same period in 2017. Spot gas prices are aligned relatively closely with export prices.
Gas Powered Generation (GPG) (electricity) continues to decline in terms of total output (MWh). This is a result of increased generation from new and existing renewable generation and batteries.
In South Australia, the increased penetration of renewable generation has made dispatchable generation from GPG plant more critical. GPG, whilst relatively expensive it is much more flexible in its operation and provides the added benefit of inertia to the NEM.
The Northern Territory’s offshore Bonaparte Basin will become a supplier to the eastern gas market with the connection of the 90 TJ/day Northern Gas Pipeline.
