Two different sorts of things, then, need to be integrated into our accounting. First, all the electricity made, no matter who is making it. And second, all the electricity not used, no matter who is saving it. If we can work out how to do this, systemically, it will start to matter when a couple of big-box stores, a cement factory, or a subdivision or two are energy-efficient enough that a utility, or anyone else, can avoid building a new power plant.
