Energy arbitrage means that ESSs charge electricity during valley hours and discharge it during peak hours, thus making profits via the peak-valley electricity tariff gap [14]. Zafirakis et al. [15] explored the arbitrage value of long-term ESSs in various electricity markets.
According to the U.S. Department of Energy, the United States had almost 25 gigawatts of electrical energy storage capacity in 2014. Of that total, 95 percent was in the form of pumped hydroelectric storage, and most of that pumped hydroelectric capacity was installed in the 1970s. The bulk of the newer installed capacity is in the form of
