Potential arbitrage revenue of energy storage systems in PJM during 2014

The price of electricity in the Mid-Atlantic (PJM) region of the United States increased during the “Polar Vortex” at the beginning of 2014. Transmission lines were congested because of high demand during the extreme cold weather. The natural gas price for electricity generation increased more than 35% at the end of 2013. Energy Storage Systems (ESS) would have helped the system to overcome many difficulties during that period. Other opportunities in energy arbitrage define the greatest scale for storage applications. Real-time and Day-ahead markets in PJM provide alternative arbitrage opportunities. Considering the prices in 2014 for 7,395 locations in PJM, results show the potential revenue for ESS for normal arbitrage and for extreme cold weather events.
