This thesis focuses on demand side developments and on the regulated aswell as the economic framework conditions those storage technologieshave to compete in and draws a clear picture of the economicfeasibility of large scale storage options in Central Europe for thecoming decades. The potential contribution of power storage to dealwith upcoming technological and economical challenges in various areasof the electricity sector is finally assessed and a recommendationconcerning future investments in one or more of the examined storagetechnology options is given.
