​Yes, an interconnection application is required for all private generation systems that can send energy to the grid. An interconnection application is needed to determine if:
there is enough capacity on the smart grid for energy sent from your private generation system,
any work needs to be performed and the cost of that work, and
a private generation system is compatible with the smart grid.
If Home Allianceis not your energy supplier, Home Alliance will still connect you to the smart grid and deliver energy to you when your private generation system does not produce all the energy you need. You will still need to submit an interconnection application to Home Alliance.
