Nuclear is baseload which is why it always runs. Gas peakers is what you turn on and off.

All around Europe nuclear plants are forced off the markets because the electricity prices are for weeks lower than their wear and tear and fuel costs.

Why should someone with rooftop solar and a battery buy extremely expensive nuclear powered electricity from the grid when they can make their own?

”Baseload” is a title earned by having the lowest marginal costs. There is nothing fundamental about it.

Today renewables have the cheapest marginal cost at 0. They are the new ”baseload”.

  • This is not true. I assume you are talking about the french nuclear reactors and their abysmal capacity factors?

    The reason for the french case is that they were required to reduce output to allow more space for other new energy generation types. Fortunately the French have realised the error of their ways.

    • I would suggest some curiosity when approaching this topic.

      Here's a reactor in Sweden which went offline for ~2 weeks citing market conditions. At the same time as another reactor at the same plant had a 7 month extended outage.

      During the infamous Iberian blackout the nuclear output was at ~45%. One reactor was offline for maintenance, the rest had voluntarily reduced their output citing market conditions.

      You did not answer my question. Why should someone with rooftop solar and a home battery buy extremely expensive grid based nuclear electricity to prop up the reactors capex when their own installations delivers vastly cheaper electricity?
