In Switzerland today, a pumped hydro facility started operation

One would need to be a stupid as an anti-nuke to not understand how hydrostorage works. I certainly don't need it described. I only note that since the energy stored is generated using dangerous fossil fuels in Germany, the filling of hydrostorage facilities is destructive, not only to the vast river basin that can store as much energy as a kg of plutonium, but to the atmosphere as well.

The Swiss have mainly hydro, nuclear and solar as their electricity producers. They have no coal and very little gas and oil.

The article plainly states that they are pumping the water from one reservoir to another. Nothing about getting supply from a river.

They also state that it is 80% efficient.

The number missing in all this is the cost to keep a power plant that uses steam to drive turbines on the ready to balance loads on the grid. If you are using steam for this then the boilers have to be kept at temp and ready to use, waiting for the need to arise - talk about wasted energy. That is the one function that the pumped hydro system in Bath County emphasized. It's also what battery storage does so well because they can respond instantaneously - no delay.
