Merit of Solar: The impact and future of solar photovoltaic generation in restructured electricity markets

Merit of Solar: The impact and future of solar photovoltaic generation in restructured electricity markets

Thursday, 13 November 2014 - 11:00am to 11:30am

Abstract:

Renewable energy capacity has rapidly expanded in recent years, as part of the global efforts to dramatically reduce carbon emissions and avoid catastrophic climate change. The addition of renewable energy capacity into restructured electricity market has been shown to markedly reduce wholesale spot prices around the world. This phenomenon, known as the “merit order effect”, has been argued to offset the cost of schemes supporting renewable energy by some, while others suggest it will necessarily increase prices in the long term, and is not welfare enhancing. These debates aside, the long-term implications of the merit order effect, for both renewable generators and liberalised electricity markets are not well understood. This research aims to investigate this issues in relation to distributed solar generation. Firstly, inversion modelling will be used to assess and characterise the contributions of rooftop solar generation to Australia’s electricity supply. Results from this analysis will then allow econometric techniques to be used to determine, estimates of the merit order effect, the impact on incumbent generator output and bidding behaviour and effect on emissions. Finally, this will allow potential short and long-term effects of renewable energy to be explore, using market modelling techniques.

PhD Project: Merit of Solar - Impact and Future of Solar Photovoltaics in the Australian Market 

Renewable energy capacity has rapidly expanded in recent years as part of global efforts to dramatically reduce carbon emissions and avoid catastrophic climate change. The addition of generation capacity been shown to markedly reduce wholesale spot prices in restructured electricity markets around the world. This phenomenon, known as the 'merit order effect', is demonstrably impacting electricity wholesale prices in Australia and abroad. On the one had, the effect has been argued to offset the cost of schemes supporting renewable energy. On the other hand, others suggest it is a wealth transfer and not welfare enhancing, leading to higher prices. Tthe long-term implications of the merit order effect, for both renewable generators and liberalised electricity markets, are poorly understood, while be critical to these debates, and renewable energy policy. This research aims to investigate this issues in relation to distributed solar generation. Firstly, inversion modelling will be used to assess and characterise the contributions of rooftop solar generation to Australia’s electricity supply. Results from this analysis will then allow econometric techniques to be used to determine, estimates of the merit order effect, the impact on incumbent generator output and bidding behaviour and effect on emissions. Finally, this will allow potential short and long-term effects of renewable energy to be explored, using market modelling techniques.
