I'm wondering what kinds of reliability we actually need. Residential: it seems like we often accept less reliability? It's common for bad weather like thunderstorms to cause power outages, particularly in rural areas. Lots of places in California will get cut off during high winds. If you need reliability, a battery backup protects you from more outages, including those that take out the grid. In some cases a generator makes sense (such as for a data center), but it's higher maintenance.
