There are two general steps involved:
1) You need to make sure you have executed an Interconnection Agreement with your local Transmission & Distribution Utility (TDU). Once your TDU confirms your system is ready, your excess generation will automatically be sent to Infuse by your TDU.
2) You need to be enrolled into one of Infuse Energy's standard green energy plans, like the Lean Green Infusion or Loyalty Green Infusion plans.
