The shovel according to the embodiment of the present invention includes a lower running body 1, an upper rotating body 3, a work attachment, an engine 11, an electric generator 12 connected to the engine 11, and an electric motor. A hydraulic pump 14 connected to the generator 12 to supply hydraulic oil to the working attachment, a swinging motor 21 mounted on the upper swing body 3, a capacitor 19, and a capacitor 19 and swinging A DC bus 110 electrically connecting the electric motor 21 and a control device 30 are provided, and the control device 30 reduces the charge/discharge limit value of the capacitor 19 as the temperature of the capacitor decreases. In addition, the discharge demand value, which is the maximum value of the electric power supplied by the capacitor 19 to the turning motor 21, is changed.
