In CA it's the same these days with the advent of community choice aggregators (CCA) [1]. If a CCA is available in your area, and you choose to use it, you pay the main utility for transmission/distribution, but the CCA for energy, both on per kWh basis. It all gets aggregated on the same (confusing) bill. Because they control the energy sourcing, CCAs can offer things like 100% carbon-free or 100% renewable plans. Some even subsidize batteries to add to homes in exchange for a portion of the stored energy capacity. 1. https://en.wikipedia.org/wiki/Community_Choice_Aggregation https://en.wikipedia.org/wiki/Community_Choice_Aggregation
