Single Choice Set

Q: Switzerland has a unique geographical location and associated challenges arising from this in regards to the power system. Which of the following statement is true?
- Batteries cannot be used to shift energy over the duration of weeks (correct)
- Batteries can also be used to shift energy over the duration of weeks
- Only large power plants such as hydro dams are a viable source of flexibility in Switzerland

Q: Seasonal storages: Which of the following statements is true?
- Batteries cannot be used in economically viable scenarios to shift energy over the duration of weeks (correct)
- Batteries are too small in capacity and consequently they do not provide flexibility to the overall system
- One can readily use the available batteries in existing devices (and new EVs, for that matter) in order to storage electricity also over
