It's rare in Germany since we have a quite large population and heavy industry compared to the renewables production. We had days with 100% renewable coverage in the past, but negative energy prices are still a rarity.
We never have been 100% renewable in the UK. It's more that we go into surplus and shutting generators down is more expensive than the price going negative. Hence we won't get huge negative prices. Connectors to other countries can only export so much.
It also only happens when:
The population of Germany is only 25% bigger than the UK, so I think the two are comparable. A larger manufacturing base will make the demand-side curve more predictable though. Still, we're largely talking about the effect of supply unpredictability.
