The article, and their sources for cost analysis, don’t appear to say, but how long is the lifespan of the production infrastructure? This detail is often left off these kinds of graphics and I have found that many articles pick 20 years as the lifespan, since that is the typical lifespan of common solar panels (not saying that can’t last longer, but 20 years is a nice easy number). This becomes problematic when leveling cost against nuclear, where the plants a built to run 50 years and often run longer. Fossil fuels to a similar extent with many running long past 50 years. Nuclear takes a long time to become profitable, around 15 years typically. Not a problem in a 50-65 year cost analysis, but certainly a problem in a 20 year scenario. Unfortunately, 20 year cost analysis are common and if the article doesn’t say what their timeline is, that is usually the case.
