Is Net Metering Available in Every State?

Availability of Net Metering by State

Net metering is available in 47 out of 50 states in the US, with the remaining three states being Louisiana, Alabama, and Mississippi. However, even in states where net metering is available, the policies can vary significantly. For example, in Texas, the Public Utility Commission (PUC) sets the rules for net metering, while in California, the utilities are required to offer net metering.

Net Metering Laws and Regulations

Net metering is typically offered to customers by their utility companies under a net metering law or regulation. These laws and regulations require utilities to allow customers to generate their own electricity and sell the excess back to the grid. The specific rules and requirements can vary by state, but typically include requirements such as a maximum system size, interconnection requirements, and net metering rates. For example, in Arizona, the maximum system size is 10 kW, while in New York, it is 25 kW.

Interconnection and Grid Tie Systems

Interconnecting a solar grid tie system to the grid requires careful planning and execution. The system must be designed and installed to meet the utility’s requirements, which can include requirements such as frequency and voltage matching, and anti-islanding protection. The interconnection process typically involves submitting an application to the utility, followed by an inspection and testing of the system to ensure it meets the utility’s requirements. In some states, the utility may also require a certificate of completion from a certified electrician.
