• Main research question: What are the benefits of a new pumped-storage power plant from an overall system perspective, especially for the integration of photovoltaics?
• Potential use cases: close the winter gap, integrate solare PV (normal and alpine), support the ES2050+ goals for RES, relieve the network during redispatch
• How can pump storages support these use cases?
• When should the pump storage be available?
  

• Pumpstorage power plants store electricity for the duration of hours to a few weeks.
• The winter gap of Switzerland is distributed at intermittent intervals with the duration of hours to a few weeks.
• The future import capacities from other European market zones to Switzerland are uncertain and could be reduced.
• Several initiatives for alpine photovoltaics aim at closing the winter gap but can not operate during night.

• Create future reference scenarios (prices, system demand, PV-generation) for different use cases.
• Quantify benefit of pump storage for different system levels (local, Swiss, European).
• Redispatch and congestion management with pump storage.
• Economic cost-benefit analysis.
