Larkspur’s electric utility
The state’s utility-territory map places Larkspur in CORE Electric Cooperative territory. As a electric cooperative, it banks exported solar as kWh credits that offset later use one-for-one.
We still confirm the utility from your bill, since service territories are drawn along lines and substations rather than street grids.
