The carbon tax and the crisis in Australia’s National Electricity Market
研究2010-2016年澳大利亚国家电力市场半小时数据，发现2012-2014年实施的碳税显著影响批发价格并改变发电结构，若持续将改变2022年危机前的发电容量构成。
Australia faced a severe energy crisis in 2022, which prompted the Australian Energy Market Operator to halt in National Electricity Market operations from June 15 to June 24. In this study, which examines half-hourly data from Australia’s National Electricity Market between 2010 and 2016, we aim to demonstrate the notable and intended consequences of the carbon tax, which was enacted in 2012 and repealed in 2014. Our findings show that this tax had a significant impact on wholesale prices. It also induced substitution effects in the generation mix. If these effects had persisted, the electricity generation landscape in 2022 would have been different. Specifically, the economic feasibility of coal would have decreased and that of gas would have increased. As a result, the composition of electricity generating capacity leading up to the 2022 crisis would have been altered.
