. Due to shortage of a controllable capacity during night, a secondary battery is strongly expected to a newly installed grid-connected wind farms in some areas of Japan. However, the battery is nowadays too expensive for a wind farm developer to keep their generation cost competitive. It is therefore strictly needed to establish an optimal battery strategy to satisfy both of stability of output and cost-effective installation. In this reports, a fundamental case study is discussed to estimate the cost for battery installation to a wind farm with output power limit operation. Using real wind condition data from a typical meteorological observatory, an annual electric energy generated from wind farms with various battery capacities is estimated regarding with a nighttime wind condition. As the result of the annual production estimation, it became clear the relationship between the battery capacity and the energy production cos
