How Much Does a Utility Interconnect Cost?

Utility Interconnect Fees: What You Need to Know

The utility interconnect fee is a payment made by the homeowner to connect their solar grid tie system to the electrical grid. This fee is set by the utility company and can vary depending on the location and type of interconnect. In some cases, the fee is waived, especially for small systems.

Factors Affecting Interconnect Fees

Several factors can affect the interconnect fee, including the size of the solar system, the type of interconnect required, and the utility company’s policies. For example, systems under 10 kW may qualify for a waived or reduced interconnect fee, while larger systems may incur a higher fee. Additionally, some utility companies may require a different type of interconnect, such as a single-phase or three-phase interconnect, which can also affect the fee.

Interconnect Process and Costs

The interconnect process typically involves a site assessment, installation of the interconnect equipment, and testing to ensure safe and proper operation. The cost of the interconnect process can range from $500 to $2,000, depending on the complexity of the installation and the type of equipment required. In some cases, the utility company may require additional inspections or tests, which can add to the overall cost. It’s essential for homeowners to work with a qualified solar installer to navigate the interconnect process and ensure compliance with utility company requirements.
