This paper examines the transmission of spot electricity prices and price volatility among the five Australian electricity markets in the National Electricity Market (NEM): namely, New South Wales (NSW), Queensland (QLD), South Australia (SA), Snowy Mountains Hydroelectric Scheme (SNO) and Victoria...
The export-import values do have some impact on the data presented here, but not enough that the trend of price vs percent wind and solar electricity generation is changed much. An OLS regression of these price data on percent wind+solar indicates a fairly strong cross-sectional tren...
or of radioactive waste. It is rather that costs have escalated wildly, making nuclear plants too expensive to build. State commissions that regulate them require that utilities provide electric power to their customers at the lowest possible price. In the early 1970s this...
While for NSW, the introduction of the CPM corresponded to a decrease in the occurrences of high price volatility periods, in QLD and VIC the likelihood of the high state has steadily increased over time. However, unambiguously for all regions, the likelihood of having high electricity price ...

Through visual comparison, the NCGHW model can fit the original sequence well, indicating that the NCGHW model is a practical technique to predict the total electricity consumption in quarterly form combined with the merit of each component. Compared with the NCGHW model, the NOFGHW model has ...
4. Life Cycle GHG Emissions Comparison Using the emissions intensity estimates developed above, GHG emissions of various energy sources were compared in the Australian context for export to China. The base case comparison is between conventional LNG, CSG-LNG and black coal when exported from ...
