This paper presents an economic analysis of the LEM-GESS and existing energy storage systems used in primary response. A 10 MWh storage capacity is analysed for all systems. The levelised cost of storage (LCOS) method has been used to evaluate the cost of stored electrical energy.
The application analysis reveals that battery energy storage is the most cost-effective choice for durations of <2 h, while thermal energy storage is competitive for durations of 2.3–8 h. Pumped hydro storage and compressed-air energy storage emerges as the superior options for durations exceeding 8 h.
Sensitivity analysis reveals the possible impact on economic performance under conditions of near-future technological progress. The application analysis reveals that battery energy storage is the most cost-effective choice for durations of <2 h, while thermal energy storage is competitive for durations of 2.3–8 h.
The rated energy ER is used to represent the storage capacity of battery energy storage, while non-battery technologies assume a denominator of 1 for full charge and discharge cycles. The Levelized Cost of Storage (LCOS) represents the normalized cost, with a discount rate (r) set uniformly at 6 % based on China's energy storage sector.
