Current trends in the modern grid are leading to the integration of energy storage technologies (ESSs), such as pumped thermal energy storage to help incorporate more variable renewable energy sources into the grid. This paper analyzes the operation of a pumped thermal energy storage (PTES) system under the grid services of energy arbitrage, regulation services, spinning and non-spinning reserve, resource adequacy, and a combination of them all. Each revenue stream is setup into an optimization problem and solved to find which revenue generating technique would generate the most revenue. The combined revenue stream was found to produce the most revenue and was subjected to a sensitivity analysis to determine if the power transfer limit or energy capacity of the PTES system had a greater effected on its revenue generating capability. The power transfer limit was found to have the greatest effect on the system’s revenue generation capability.
