It is actually very interesting to look at different power plants' startup price thresholds. Nukes and wind are always on, as they cost littleöto keep "on". Hydro depends on time of year, reservoir size etc. Coal is kind of in the middle. If you use the waste heat for district heating in the winter, the logic changes. Natural gas is the last thing turned on. The plants are really cheap to build but gas costs a lot. Depends if you have a deal with Russia. It is an interesting and multifaceted field.
