Many businesses can now perform the traditional functions of an electric utility — provide affordable, reliable, resilient power to homes and businesses. The barriers to entry in the business have fallen. For instance, a home with rooftop solar panels, batteries, and gas-based generators may choose to be grid-independent. Even when homes decide to remain grid-tied, utilities face falling demand and revenue, and the possibility of future grid-defection. Further, competing electricity solutions can emerge quickly, and not one-home-at-a-time — microgrids can offer community, village, or campus-level solutions.
