What is an Interconnection Agreement?
Interconnection agreements between solar customers and the utility company are the approval process to allow a homeowner to operate a power generation system (solar energy system) in parallel with the utility grid.
The utility company will conduct an engineering analysis to see if equipment upgrades are needed to the utility infrastructure. These costs may be given notice to the customer prior to construction and are typically billed to the customer upon approval of the work to be completed.
Who takes care of this process?
A reputable solar contractor such as Sandbox Solar will coordinate these agreements between the customer and the utility by providing the necessary information, documentation, and permitted construction to ensure your power generation system runs smoothly.
Why do I need an Interconnection Agreement?
The grid company is concerned with the overall safety of its transformers, lineman, and other assets that allow it to operate. These agreements ensure that the power generation system is safely connected to the grid so that the utility is aware of the power being generated and that its workers and assets are safe at all times. These agreements define liability so that the homeowner maintains ownership of the power generation system and is solely responsible for the operation and maintenance.
