Turning the nuclear plant back on would have been even better. And then putting a battery next to it would have been even better then that.

With batteries one could argue building them in a more distributed way might make more sense for overall resiliancy.

A fleet of like 70 nuclear plants at maybe 50 location could likely power all of Germany. For batteries you would likely go to 100 to 1000s of locations.

But that said, using the existing connections in some places does make sense.

No. the battery storage will deliver more power than the plant.

But, there are other issues: Atomic power keeps rising in cost. The plant was decomissioned and to turn it back on, you would basically have to rebuild it from the ground up - with people and knowledge that does not exist. Also, you would need the fuel from some place - as with oil and gas, you are depended on that place, since you can't easily switch uranium.

We would need about 55 power plants in Germany. At its height, Germany had 38 plants, all of that trash is still not solved. And we are not even thinking about the lawsuits that the reactivation or building of new plants would entail. People are suing against solar farms, what do you think a Nimby would be triggered by a nuclear plant?

In addition, none of these plants can be insured, all the risk is with the tax payer. As russia currently shows, you are also creating about 50 targets that to destroy a country. You don't even have to send a rocket, a few drones with grenades will make sure the plant has to shut down.

Personally, I do not want them. I remember Tchernobyl and the fallout afterwards. We have alternatives, like these battery storages, and can use water, wind, solar and hydrogen to not create potential nuclear issues, i am fine with that.

< For batteries you would likely go to 100 to 1000s of locations.

Yes, ideally de-centralized and build where power is generated. A battery park can be set up almost anywhere, a power plant not so much.

Nevertheless, I like the idea of using these old plant sites for storage, they have pretty good connections to the grid, so it makes a lot of sense. Can't use that space for anything else, really.

Why do you think it would be better or even possible to turn on an old nuclear power plant that is 4 years out of service and decommissioned (10 years left until the decommission is finished)?

Even if it is possible I have no confidence that Germany is able to come up with a solution to nuclear waste. The federal states that are proponents of nuclear energy like Bavaria refuse to even examine whether a nuclear waste repository could be located in their territory.

Not that far away from the former nuclear plant in the article the "Schacht Asse" [1] is located where the problem of nuclear waste im Germany becomes painfully obvious.

Why would it have been better to turn back on the nuclear plant? What would be the specific advantages of nuclear plant back in operation versus battery project realisation? Or would battery + reactivated plant be the best overall solution?

Sure if it's the same price.

An NPP doesn't benefit that much from a battery. They're generally used to provide base load which fits their constant supply profile. Peaks and quick variations can be supplied by more flexible renewables together with a battery to buffer it.
