This is an excellent piece because it does the one thing the “wind and solar are cheapest” story cannot survive. It itemizes reliability. Your 1 GW, 10-day calculation makes the cost visible.

The central dodge in renewable economics has always been the use of LCOE as if unreliable and reliable electricity were interchangeable. Lazard’s own description says LCOE “does not take into account reliability-related considerations.” Those considerations are the whole story when a dunkelflaute arrives. Your essay prices exactly what the headline metric excludes. LCOE is cheap because it deletes the dark doldrums. You put them back on the bill.

I also think your “four systems” point is the right structural insight. Calling wind and solar a power system already grants too much. They are an intermittent fuel-saver attached to a real power system. Since they can fall toward zero during the very periods when people still need electricity, they cannot meaningfully reduce the need for reliable capacity. The gas fleet still has to exist, the grid still has to be built, and the capital still has to be paid for. The honest comparison is the reliable grid we need anyway, plus an optional weather-dependent layer that sometimes saves fuel and never eliminates the underlying system.

Your line that “the storage problem isn’t waiting for a breakthrough. It’s waiting for people to do the multiplication” is exactly right. I would add that the multiplication has been actively avoided. An entire policy and finance apparatus depends on treating intermittency as someone else’s problem and reliability as an external detail.

The most important fact in your piece may be that the backup fleet is the indispensable power source when the weather system fails. That is the fact the “cheaper than fossil fuels” narrative is built to avoid.
