This research presents a preliminary cost analysis and estimation for superconductor used in superconducting magnetic energy storage (SMES) systems, targeting energy capacities ranging from 1 MJ to 1 GJ, relevant for power grid and industrial applications. Utilizing high-temperature superconductor (HTS) rare-earth barium copper oxide (REBCO) coils in SMES can help compensate for power quality degradation and enhance power stability. However, the high capital costs of SMES remain significant challenges, with costs varying across different energy capacities. First, SMES designs in solenoidal configurations are presented and compared, considering design parameters such as total conductor length, operating current, and magnetic field at the coil center. Then, preliminary cost estimates of these designs are provided based on the price of superconductor. This analysis offers insights into the economic considerations for superconductor in SMES designs and highlights the potential benefits of implementing HTS REBCObased SMES systems across various applications.
