If the price is -5$ in France, but still $7 in Germany, why not dump all that excess energy to Germany?
Not enough interconnect capacity https://montelnews.com/news/1525872/france-to-miss-2030-inte...
Electricity prices in France turn negative as renewable energy floods the grid

French reactors are built to load follow [1]. It is harder on the valves, but they do it ("maneuvering capabilities"). Regardless, it would be better if they could run flat out to push out fossil generation in adjacent grids (Germany, the UK, and Northern Italy) with sufficient interconnector capacity. France also still has a bit of coal and fossil gas generation to retire [2] [3]. TLDR More interconnector capacity,…
Which theyve actually used very very rarely. Nuclear reactors are already very cost ineffective when used as baseload. Theyre ridiculously cost ineffective when used for load following since it's basically curtailment. This is why most countries tend to use gas or hydro/pumped storage for load following (or, increasingly, batteries as theyve been plummeting in price).
It's untrue, it is used everyday on all our Gen3/Gen3+ reactors (our Gen2 are able to do it too, but it does cost a lot as core monitoring is more costly for them)
I've found this https://www.oecd-nea.org/nea-news/2011/29-2/aen-infos-suivi-... even if it isn't really clear, you have a graph that show you a typical year on a french reactor, and load followinf the german reactors used to do over a day.

There isn't enough transmission line capacity to transfer all of it.

#24They ought to flood something towards Denmark. Right now, in this moment, I pay roughly 0.49€ (3.66 DKK) per kWh.
Let’s run a crowdfunding campaign for the cable. I’m midway and will want a piece of that as well.

Negative prices make storage very practical
And de-incentivizes supply. A real solution need to be available to balance the supply and demand of power such that the rates on both ends are predictable. A market where a good fluctuates between profitable and not is not one very attractive to investment. Playing the video game Victoria 3 has taught me a lot about healthy markets. You have to play both sides of supply and demand to get to the prices you need
Negative prices do incentivize storage, because storage will alliw sellers to sell at a time with higher prices (i.e. when demand is greater relative to supply).

#26What I never understood was how France gets 70-75% of their electricity from Nuclear, yet their energy prices aren't "too cheap to meter", and while cheaper than their neighbors, don't really raise any eyebrows. Wouldn't this be a major example of why Nuclear is NOT the future?

#28Potentially ignorant question. How does this impact the consumer? Do they actually get paid/credited for electricity used?
Re: Electricity prices in France turn negative as renewable energy floods the grid
#29This happens frequently in the UK too, if you have a compatible supplier you can set it up to charge your EV or some batteries during negative spikes. Ultimately if enough people were set up that way then prices would not get negative I suppose.

I'm confused. The way you've phrased this certainly doesn't sound like it couldn't be the future.
