We would like to thank many contributors who have made designs and measurements for this HTS-SMES project. This work was supported by the New Energy and Industrial Technology Development organization (NEDO), under the Research and Development of Superconducting Magnetic Energy Storage System project sponsored by the Agency of Natural Resources and Energy, Ministry of International Trade and Industry (MITI).

N2 - HTS-SMES has high potential to increase efficiency and future cost reduction. Therefore, MITI started new national project on feasibility study of HTS-SMES in FY 1999 for five-year project, as a sub-program of LTS-SMES cost reduction project, that is a succeeding project of 100 kWh SMES key technology development to FY 1998. In FY 1999, parameter survey has shown that 15 kWh class HTS-SMES can be realized by both of Bi-2212 and Bi-2223 wire operated at around 20 K with reasonable sizes by conduction cooling. As for Y-system wires, operating temperature around 77 K is rather high to have magnetic field to store enough energy. Lower temperature operation was suggested. Mechanical strength tests on Bi-2212 Rutherford cable revealed that they could withstand tensile strain up to 0.6% without Ic degradation. This allows high flexibility in mechanical design of HTS-SMES.
