1 week ago, Spain was plunged into darkness, and in the days that followed a traditional / social media firestorm cynically exploited the catastrophe: blaming it on Spain's solar power and calling for more fossil fuels and nuclear to 'save' the grid.

So: I decided to look at the longer-term data, and I found that nuclear power in Spain was operating at its lowest levels of generation in at least ten years (if not longer). We have almost no information on why, but one operator blamed power prices being too cheap to run nuclear.

I have been pretty bloody stunned at the total absence of media questions around Spain's nuclear fleet, why so much capcacity was being intentionally withheld at the time of the blackout, and what their stated rationalisations mean for the future of grid stability, power prices and variable renewable energy.

So - here's a hefty, data-driven write-up for you. Enjoy! :)
