H.B. 1342 of 2010 authorized the development of community solar gardens (CSGs) in the service territory of investor-owned utilities in Colorado. H.B. 1003, enacted in 2019 increased the maximum size of a CSG from 2 megawatts to 5 megawatts, and allowed the Public Utilities Commission (PUC) to increase the maximum size to 10 megawatts beginning July 1, 2023. The legislation also removed the requirement that a CSG subscriber's identified physical location be in the same or adjacent county as the CSG, though both locations must be within the service territory of the same investor-owned utility. 

Subscriptions must be at least 1 kW and cannot exceed 120% of the subscribers average annual electricity consumption. Subscribers are credited at the total aggregate retail rate.
