If you pump the water back into the existing reserviors you will have less flooding?

I suggested a pump-water extension to existing hydro power reservoirs.

Like your EV recharges when you release the pedal.

Right shouldn't talk about EVs with a Finn, that analogy will not fly. Ok, like if you plan carefully where you throw up your koskenkorva you can re-use it.

The reservoirs in Finland aren't quite at the scale your Explorer Vodka-fuelled Swedish mind believe them to be. Most are small generators hooked up to the local rivers, and are required to prioritize keeping the water from flooding residential areas.

There's a reason we're looking at using old mines for pumped hydro rather than trying to pump water upriver during a spring flood because other power sources have surplus generation.
