1. A method for providing control power, the method comprising:

  • delivering the control power based on a frequency deviation from a setpoint value of a network frequency to discharge or change an energy store for supplying energy to an electricity network or taking up energy from the electricity network respectively, a charging state of the energy store being in one of (i) an upper charging state, (ii) a medium charging state, and (iii) a low charging state, amount of the charge in the medium charging state being less than amount of charge in the upper charging state and the amount of charge in the medium charging state being more than amount of charge in the low charging state, whereinthe delivered control power is varied within a tolerance with respect to the frequency deviation to discharge or charge the energy store to move the charging state toward the medium charging state.
