Our results demonstrate that arbitrage opportunities exist in less integrated markets, characterized by significant reliance on energy imports and lower level of market competitiveness. We show that, among all strategies tested, arbitrage value maximizes for the weekly back to back energy trade strategy. Moreover we estimate the optimum size of energy storage systems in terms of arbitrage value for each different electricity market and evaluate the potential of arbitrage to support investment in the sector. Finally, it is argued that energy storage can take over multiple roles as a necessary positioning to facilitate financial profitability. (C) 2016 Elsevier Ltd. All rights reserved. 收起
