ItemRenewable Energy Technology Cost Review(Melbourne Energy Institute, 2011-05-01)This paper undertakes a review of current and future costs of three forms of renewable energy technology by comparing data from a range of international and Australian-specific studies, taking care to compare data on the same basis of financial assumptions (discount rates) and resource quality. The purpose was to compare the absolute costs and the rate of decrease in costs, and to understand the reason for differences between the studies. The Australian-specific datasets are the ‘Australian Energy Generation Technology Costs’ report by the Electric Power Research Institute (EPRI), and the 2010 dataset used by the Australian Energy Market Operator (AEMO), largely based on the EPRI data with a review from ACIL Tasman. The assessment reviewed technical and economic parameters of wind, photovoltaic (PV) and concentrating solar thermal (CST) energy generation technologies, considering technology specific learning rates and cost reduction potentials. It includes a detailed exploration of the factors contributing to the learning rates and cost reductions. Levelised Cost of Energy (LCOE) calculations were used to develop cost outlooks and compare the outlooks to other projections. Where relevant, LCOE is calculated from capital and operating cost data at a common renewable resource level, exclusive of subsidies or carbon costs. Common financial assumptions (in particular discounting rates) are used to provide a consistent basis of comparisons and analysis.

ItemRegulation in the NEM(Melbourne Energy Institute, 2012-03-01)This briefing paper aims to explore the regulatory frameworks and institutions relevant to the development of the photovoltaic (PV) industry today. This covers both the institutions involved in the current electricity market arrangements as well as regulatory bodies specifically relevant to PV and renewable technologies in general.

ItemImpact of Renewable Generation on the Philippine Wholesale Electricity Spot Market(Melbourne Energy Institute, 2013-06-08)Renewable generation has been shown to depress wholesale electricity prices in liberalized or deregulated electricity markets, through an effect known as the “merit order effect”. This study aimed to quantify the “merit order effect” for renewable generation in the inter-connected Luzon and Visayas electricity markets.

ItemOpportunities for Pumped Hydro Energy Storage in Australia(Melbourne Energy Institue, 2014-02-27)Pumped hydroelectricity energy storage (PHES) is by far the most significant form of large-‐scale energy storage in use around the world today with approximately 130 GW of generation capacity installed. PHES facility construction is resurging globally as evolving electricity supply systems place greater value on stored energy. Australia has approximately 1.5 GW of PHES capacity; however, no large-‐scale facilities have been installed in the last 30 years. This paper examines opportunities for the construction of additional large-‐scale PHES facilities in Australia.
