The National Electricity Market was established in 1998 as a response to the overall deregulation and restructuring of the Australian electricity sector. The wholesale market integration effects of this establishment, however, remain to be examined. We use pairwise unit root tests, cointegration analyses and a time varying coefficient model to determine the level and study the development of market integration in the regionally separate but interconnected markets in Australia. The results from the pairwise unit root tests provide a mixed evidence of price convergence while cointegration analyses does not clearly reject the absence of persistence price differences across the physically interconnected regions. The results from the time-varying coefficient model suggest an integrating market for electricity in Australia although full market integration has not been achieved yet. The results suggest the presence of significant transmission bottlenecks across the inter-regional interconnectors. Our results from cointegration analysis also supports the findings by Gonzalo and Lee (1998) that a proper use of the Johansen cointegration analysis requires a deeper data analysis than just the standard unit root tests.
