Pumped storage is now increasing its importance as the most powerful and reliable tool for stabilizing the electrical network, especially under the increase of intermittent power sources like wind-power and solar-power. However, pumped storage power plants have generally more machinery troubles than the conventional hydropower plants and sometimes they encountered unexpected severe incidents having long-term outage and a considerable restoration cost. The present paper provides some study results about general tendencies of machinery troubles in pumped storage, some examples of severe incidents mainly about the electro-mechanical troubles but also about the flood and fire, and possible scenarios which may lead into a severe result. Finally, it provides lessons learned and some recommendations to avoid severe incidents based on experiences.
