When they come to Europe (CH at least), Tesla's gonna eat up the lunch (in the ancillary services field at least) of everyone. Even more so with the new renewable capacity added every day.
I dunno, it seems like the function of these Megapacks is to replace natural gas driven peaker plants? Europe doesn't have nearly as many of those as the US does.
AFAIK Switzerland in particular has exactly zero, thanks to all that lovely hydropower that can be turned on and off to match solar/wind fluctuations.
In fact, Switzerland alone has hydropower equivalent to 10 000 Megapacks. This basically means you can install all the renewables you want.
The coal and nuclear phase outs across Europe will lead to a need for new flexible capacity. That should at least partly be covered by battery peakers.
Nuclear isn't flexible capacity; plants are always run at max output. If it is to be phased out the replacement needs to have more long-term output than a battery, unless the renewables become incredibly overprovisioned.

In France and Germany, nuclear reactors are configured and permitted to run in load following mode. It's harder on the valves and similar equipment, but it can and is done. [1]

Which is the likely outcome, as solar and wind are still declining in cost and in some places the cost is as low as 2 cents/kwh. The generation will be cheap (what's the old saying? "too cheap to meter"?), and it'll be the storage that'll cost a bit more.
US companies are not permitted to eat the lunch of European state-owned companies in Europe. If it's not illegal now, it will be before it's profitable.
