Small private solar stations are vastly better than centralized power plants because their decentralized nature generally help with grid stability and are ultimately also add redundancy in possible events of failures (including possible attacks). But in either case, you need to update your grid to become smarter and distribute loads better, as well as having storage solutions, big and small (small decentralized storage should not be snuffed at because it eventually accumulates too). If you just sit on your ass and do nothing then yeah, your grid will suffer and eventually your whole electricity supply. We have NIMBY states like this in Germany too and at this point I'm all for cutting power to them if they want neither power generation nor distribution being build in their area. I don't see why we should power those fucks when they're blocking the whole progression so hard.
