I am totally in agreement, that nuclear plants shouldn't be shut down before fossil ones.
A decentralized grid sound way more resilient, then one with a few nuclear plants, which often have long unexpected downtimes (see France). I agree with you on the potential logistical dependencies, however that sadly applies to nearly everything right now.
- mulmen 1y agoBy definition the grid is decentralized. That’s what makes it a grid. Resiliency of the grid is a function of excess capacity but not the number of nodes.
- V__ 1y agoI am no expert but remembering the grid outage in Spain this year, which was caused by a substation or node failure and not by a capacity problem. Wouldn't it be fair to describe resiliency as a combination of both capacity and nodes?
- StopDisinfo910 1y agoYes, interconnectedness is critical if you want reliability. Spain has far too little transnational capacities. That was a significant contributing factor in the grid outage.
- mulmen 1y agoIf you want to change the topic of this conversation to distribution resiliency instead of production resiliency then sure.
- V__ 1y agoI had both of these as a single concept in my head, thus the confusion.
- mpweiher 1y agoThe Spainout was caused by having too little rotating mass in the grid that stabilizes the frequency. There was a trigger in some of the PV systems, but that wasn't the underlying cause.
- StopDisinfo910 1y agoThe French grid has been extremely resilient with only a minor setback a couple years ago when multiple plants were in maintenance at the same time and that’s despite not significantly investing in it for decades. Technically, a grid based on nuclear production is also a distributed grid. You have multiple plants and it’s easy to add overcapacity to the grid because nuclear is easy to modulate.
- V__ 1y agoThis year again multiple nuclear plants in France had to reduce their output due to heatwaves and water levels, and ongoing cooling concerns. This is becoming a yearly occurrence. Though, I am not saying you can't have a nuclear grid, or you shouldn't use it at all, it's just that renewables seem to be a much better solution for most cases.
