90% capacity factor is possible but quite generous, France is below 70%. As nuclear penetration goes up it becomes impossible to sustain high capacity because demand itself is variable, so you either need to overbuild nuclear and run nuclear at low capacity factors, or you need to build storage.
I'm very shocked to see that China's utility scale solar project is $600 per kwp. I almost want to say something must be wrong with that number. It's higher than retail rooftop PV costs which is $450 per kwp.
- amenhotep 2y agoPresumably for rooftop costing you regard the roof itself and the land it sits on as being "free", whereas for a power plant you have to account for everything? Still seems a bit of a stretch for it to make that much difference but... possible?
- philipkglass 2y agoIt's higher than retail rooftop PV costs which is $450 per kwp. Which country is that in? I don't know of any country where you can get e.g. a 5 kilowatt rooftop system installed for $2250 (except perhaps with special government tax credits/incentives). The costs for this Chinese project include not just the PV modules but the land, racking, inverters, transformers, grid connection, and installation labor.
- hackerlight 2y agoAny developing country that has cheap labor costs and no tariffs. The retail cost for panels is $205 per kW, inverter $115 per kW, then add another 30-40% for labor, cables and mounts.
