In December 2005 the Colorado Public Utilities Commission (PUC) adopted standards for net metering and interconnection, as required by Amendment 37, a renewable energy ballot initiative approved by Colorado voters in November 2004. The interconnection rules were overhauled in July 2021.

The PUC standards generally apply to investor-owned utilities (IOUs) with 40,000 or more customers and all electric cooperatives. Municipal utilities with 5,000 customers or more are required to adopt interconnection rules that are functionally similar to the PUC's standards (see H.B. 08-1160). Electric cooperatives and municipal utilities may reduce or waive any insurance requirements that apply to IOUs.

Golden Valley Electric Association's (GVEA) SNAP program encourages members to install renewable energy generators and connect them to the utility's electrical distribution system by offering an incentive payment based on the system's production on a dollar per kilowatt-hour ($/kWh) basis. The amount paid to participating renewable energy producers depends on the total amount contributed by GVEA supporters.

“Qualified alternative energy resources" includes electricity produced from generation facilities that are fueled by: (a) wind; or (b) solar energy and other renewable energy resources. GVEA limits these resources to 25 kilowatts of capacity or less per system.

The Solar Rights Act (CA Civil Code 714), enacted in 1978, bars restrictions by homeowners associations (HOAs) on the installation of solar-energy systems, but originally did not specifically apply to cities, counties, municipalities or other public entities. Subsequent legislation extended these restrictions to all public entities and common interest developments.  These entities are allowed to impose reasonable restrictions on a solar energy system that do not significantly increase the cost of the system or significantly decrease its efficiency or specified performance. 

"Significantly" was not originally defined, but later legislation adopted a specific dollar amount and system efficiency impact that the
